Cleco Corporation

          We are a regional energy services company operating principally through Cleco Power LLC, our subsidiary that conducts our traditional electric utility business, and Cleco Midstream Resources LLC, our subsidiary that conducts our merchant energy business.

Cleco Power

          Cleco Power is an electric utility regulated by the Louisiana Public Service Commission and the Federal Energy Regulatory Commission, among other regulators. Cleco Power provides electric utility services, including generation, transmission and distribution, to approximately 265,000 retail and wholesale customers in 103 communities in central and southeastern Louisiana.

Cleco Midstream

          Cleco Midstream is a subsidiary with operations in Louisiana and Texas that are not regulated by the Louisiana Public Service Commission or the Public Utility Commission of Texas. Cleco Midstream owns and operates two wholesale electric generation stations and invests in joint ventures that own and operate merchant generation stations. As of March 31, 2005, Cleco Midstream owned approximately 2,100 megawatts, or MW of electric generating capacity, including a 718-MW plant the sale of which is pending.

          On January 28, 2004, Perryville Energy Partners, L.L.C., an indirect wholly owned subsidiary of Cleco Midstream, entered into an agreement to sell its 718 MW power plant located near Perryville, Louisiana, which we refer to as the Perryville power station, to Entergy Louisiana, Inc., a subsidiary of Entergy Corp., for $170.0 million, subject to certain adjustments. The sale agreement was amended by Perryville Energy Partners and Entergy Louisiana in October 2004 to exclude certain jurisdictional assets in order to eliminate the need to obtain Federal Energy Regulatory Commission approval of the transaction under Section 203 of the Federal Power Act and to extend the closing date to a date no later than December 31, 2005. As part of the transaction, Perryville Energy Partners and Perryville Energy Holdings LLC, a subsidiary of Cleco Midstream and the parent company of Perryville Energy Partners, filed voluntary petitions in the U.S. Bankruptcy Court for the Western District of Louisiana in Alexandria for protection under Chapter 11 of the U.S. Bankruptcy Code. The bankruptcy court approved the amended sale agreement utilizing the alternative structure on December 8, 2004. On April 20, 2005, the Louisiana Public Service Commission approved the amended sale agreement and issued a final order on May 3, 2005. The sale of the Perryville power station pursuant to the amended sale agreement is subject to various approvals and conditions, including regulatory approvals and conditions and approvals by Entergy Louisiana in its sole discretion, and is expected to be completed by the third quarter of 2005.

          In July 2001, Perryville Energy Partners and Mirant Americas Energy Marketing, LP, a subsidiary of Mirant Corporation, entered into a 21-year capacity and energy sale agreement providing for Mirant Americas Energy Marketing’s use of the entire capacity of the Perryville power station. In July 2003, Mirant, Mirant Americas Energy Marketing and other subsidiaries of Mirant filed for protection under Chapter 11 of the U.S. Bankruptcy Code and subsequently rejected the Mirant Americas Energy Marketing tolling agreement. In May 2005, Perryville Energy Partners and the Mirant companies who filed for bankruptcy protection entered into an agreement to settle all claims against each other. The settlement is subject to, and conditioned upon approval of the settlement by the bankruptcy courts which are presiding over the Mirant companies’ and Perryville Energy Partners’ Chapter 11 cases and the approval orders becoming final.

Risk Factors

          There are many risks that may affect your investment in our securities. You should carefully consider these risks as well as the other information we have provided in this prospectus, the accompanying prospectus supplement and the documents we incorporate by reference, before reaching a decision regarding an investment in our securities.

          If the pending sale of the Perryville power station to Entergy Louisiana were not to be consummated, we would likely seek another purchaser of the facility or its generation or Perryville Energy Partners’ obligations would be resolved in its ongoing bankruptcy proceedings, any of which could result in Perryville Energy Partners receiving significantly less value than anticipated for the facility and additional losses.

          On January 28, 2004, Perryville Energy Partners reached an agreement to sell the Perryville power station to Entergy Louisiana for $170.0 million, subject to certain adjustments. The sale agreement was amended by Perryville Energy Partners and Entergy Louisiana in October 2004 to exclude certain jurisdictional assets in order to eliminate the need to obtain Federal Energy Regulatory Commission approval of the transaction under Section 203 of the Federal Power Act and to extend the closing date to no later than December 31, 2005. As part of the transaction, Perryville Energy Partners entered into a power purchase agreement with Entergy Services, Inc., which has since been amended and approved by the Louisiana Public Service Commission, under which Entergy Services makes certain payments to Perryville Energy Partners and supplies natural gas to the Perryville power station in exchange for which Entergy Services is exclusively entitled to all of the electric generation capacity of the facility until the earlier of the closing or termination of the sale of the facility or December 31, 2005. Also on January 28, 2004 and in connection with the sale, Perryville Energy Partners and Perryville Energy Holdings filed voluntary petitions for protection under Chapter 11 of the U.S. Bankruptcy Code. The bankruptcy court approved the amended sale agreement utilizing the alternative structure that excludes certain jurisdictional assets on December 8, 2004. On April 20, 2005, the Louisiana Public Service Commission approved the amended sale agreement and issued a final order on May 3, 2005. Consummation of the sale utilizing the alternative structure is contingent upon Entergy Louisiana confirming to its satisfaction its ability to recover through regulatory mechanisms all of its costs in acquiring the Perryville power station, obtaining necessary approvals from the Louisiana Public Service Commission and the Securities and Exchange Commission, final inspection by Entergy Louisiana and other customary closing conditions. The sale is expected to be completed by the third quarter of 2005.

          The outstanding amounts due under the Construction and Term Loan Agreement, dated as of June 7, 2001, between Perryville Energy Partners and KBC Bank N.V., as Agent Bank, which we refer to as the senior loan agreement, were deemed accelerated upon the bankruptcy filings of Perryville Energy Partners and Perryville Energy Holdings. As of March 31, 2005, there was $126.2 million of outstanding principal and accrued interest payable under the senior loan agreement. Cleco Corporation has provided a guarantee to pay interest and principal under the senior loan agreement should Perryville Energy Partners be unable to pay its debt service for amounts up to $0.5 million (as of March 31, 2005). As a result of the commencement of such bankruptcy cases and by virtue of the automatic stay under the U.S. Bankruptcy Code, the lenders’ ability to exercise their remedies under the senior loan agreement, including, but not limited to, their ability to foreclose on the mortgage or assume ownership of the Perryville power station, are significantly limited and would require approval of the bankruptcy court.

          In July 2003, Mirant Corporation and certain of its subsidiaries filed for protection under Chapter 11 of the U.S. Bankruptcy Code and subsequently rejected the Mirant Americas Energy Marketing tolling agreement. In May 2005, Perryville Energy Partners and the Mirant companies entered into an agreement to settle all claims against each other in their respective Chapter 11 cases. The settlement is subject to, and conditioned upon approval of the settlement by the bankruptcy courts which are presiding over the Mirant companies’ and Perryville Energy Partners’ Chapter 11 cases and the approval orders becoming final.

          During 2003, the carrying value of the Perryville power station was reduced resulting in Cleco recording impairment charges of $148.0 million ($91.0 million after tax).

          If the sale of the Perryville power station to Entergy Louisiana were not to be consummated, the power purchase agreement with Entergy Services would terminate automatically. If this were to occur, we would need to seek an alternative purchaser of the Perryville power station or its generation, or allow Perryville Energy Partners’ senior loan agreement and other obligations to be resolved in Perryville Energy Partners’ and Perryville Energy Holdings’ bankruptcy proceedings. Any of these alternatives could result in us receiving significantly less value for the Perryville power station and its generation than anticipated, as well as possibly causing us to record additional losses on our investment and under certain circumstances requiring us to pay $10.0 million in liquidated damages to Entergy Louisiana if the sale is not consummated.

          The ability of our counterparties to satisfy their payment obligations under key agreements relating to our merchant power plant operations has become less certain, placing a significant source of our revenue and other income at risk; failure by our counterparties to perform their obligations under these key agreements would likely have a material adverse impact on our results of operations, financial condition and cash flow.

          Our Cleco Midstream energy business derives a substantial portion of its earnings from tolling agreements relating to its power plants. These tolling agreements give the counterparties the right to own, dispatch and market all of the electric generation capacity of the respective facility in exchange for fixed and variable fees. Currently, Cleco Midstream’s equity earnings from investees are derived primarily from a tolling agreement with Williams Power Company, Inc. (formerly Williams Energy Marketing & Trading Company), a subsidiary of The Williams Companies, Inc., and from its 50% interest in Acadia Power Partners LLC, which derives its revenues from two tolling agreements with Calpine Energy Services, L.P., one of which relates to Power Block 1 of the Acadia Power Partners electric generation facility and the other of which relates to Power Block 2 of the Acadia Power Partners electric generation facility. Perryville Energy Partners previously was party to a tolling agreement with a subsidiary of Mirant Corporation, which agreement was terminated in September 2003 in connection with Mirant’s Chapter 11 bankruptcy filing.

          The credit ratings of the senior unsecured debt of The Williams Companies, Inc. (Moody’s Investors Service — B1; Standard & Poor’s Ratings Services — B+) and Calpine Corp. (Moody’s — Caa1; Standard & Poor’s — CCC+), the respective parent companies of the counterparties under these tolling agreements, have been downgraded and/or put on negative watch by one or more credit rating agencies at least once in recent years and remain below “investment grade.” These downgrades indicate that our counterparties’ ability to perform their payment obligations under the tolling agreements may be impaired.

          Since May 2004, Calpine Energy Services has made various allegations regarding its tolling agreements with Acadia Power Partners. In connection with these allegations, Calpine Energy Services has notified Acadia Power Partners that it may withhold up to one-half of the monthly payments due Acadia Power Partners under the tolling agreements and may take other action, including, without limitation, (i) unwinding Calpine’s interest in Acadia Power Partners, (ii) terminating the tolling agreements, (iii) asserting claims against Cleco Power for allegedly flawed interconnection studies and/or (iv) seeking reimbursement for the alleged overpayment of capacity fees from August 2003. Calpine Energy Services has indicated that the dispute is primarily based upon transmission constraints that, according to its allegations, limit its ability to deliver Acadia Power Partners’ capacity and energy to the wholesale market. Under the tolling agreements, binding arbitration is a means of resolving the alleged dispute. On March 8, 2005, Calpine Energy Services requested a refund of approximately $2.3 million from Acadia Power Partners. Calpine Energy Services claims that natural gas metering errors caused errors in calculating the heat rate performance of Acadia Power Partners’ facility from January 2003 through July 2004. Our share of any refund that Acadia Power Partners may be required to make, and the timing of any accrual that Acadia Power Partners may be required to make in connection with this matter, cannot be estimated at this time. On April 12, 2005 and May 3, 2005, Calpine Energy Services informed Acadia Power Holdings that they intend to initiate binding arbitration proceedings pursuant to the tolling agreements due to the alleged failure to resolve transmission constraint issues. In addition, on June 1, 2005, Calpine Energy Services sent a written notice to Acadia Power Partners requesting that the scheduled June 2005 annual capacity test of the Acadia Power Partners electric generation facility be conducted as a simultaneous test of both power blocks and stating that it would deem a failure to comply with the request to be a material default under the tolling agreements. Acadia Power Partners’ position is that it is not required to conduct a simultaneous test, but it has informed Calpine Energy Services that it would conduct such a test under protest, while reserving all of its rights to contest

the validity of any test not performed in accordance with the tolling agreements. As of June 8, 2005, Calpine Energy Services has not invoked arbitration, and settlement discussions between the parties are ongoing. Through May 2005, Calpine Energy Services has continued to remit full payment (other than the periodic withholding of disputed billing amounts) of the monthly tolling fees to Acadia Power Partners. For the twelve months ended March 31, 2005, Cleco’s share of Acadia Power Partners’ net income was $27.2 million and cash distributions by Acadia Power Partners to Cleco were $35.8 million.

          If Calpine Energy Services or Williams Power Company were to fail to perform their obligations under their respective tolling agreements, it could have a material adverse impact on our results of operations, financial condition and cash flow. In addition, we may not be able to enter into agreements in replacement of our existing tolling agreements on terms as favorable as our existing agreements or at all. If any of the foregoing were to occur, our credit ratings could be downgraded. Our senior unsecured debt is currently rated Baa3 by Moody’s and BBB- by Standard & Poor’s, with a negative outlook in each case. The occurrence of any of the foregoing would likely be considered by the board of directors in determining the payment of future dividends on shares of our common stock.

          Periodic Louisiana Public Service Commission audits could result in Cleco Power making substantial refunds of previously recorded revenue.

          Although the July 2004 settlement of the Louisiana Public Service Commission’s audit of Cleco Power’s recovery of fuel and purchased power expenses resolved the payment of these expenses for 2001 and 2002, the Louisiana Public Service Commission is required by order to conduct such audits every other year. Any such audit could include periods prior or subsequent to the 2001-2002 period, and Cleco Power could be required to make a substantial refund of previously recorded revenue as a result of such an audit.

          A significant portion of Cleco Power’s power supply comes from sources other than the facilities Cleco Power currently owns, and future long-term sources of such additional power are uncertain.

          Cleco Power does not supply all of its customers’ power requirements from the generation facilities it owns and must purchase additional power from the wholesale power market. During 2004, Cleco Power met 53.7% of its capacity and energy needs with purchased power. Three long-term power purchase agreements with Williams Power Company and Dynegy Power Marketing, Inc., a subsidiary of Dynegy Inc., provided approximately 35% of Cleco Power’s capacity needs in 2004. All but 100 MW of Williams Power Company’s and Dynegy Power Marketing’s obligations to supply power to Cleco Power under these agreements expired on December 31, 2004.

          In 2003, Cleco Power initiated a solicitation to identify existing or new generation resources for 2005 and subsequent years, but no satisfactory proposals were received. In May 2004, Cleco Power signed a one-year contract to purchase 500 MW of capacity and energy from Calpine Energy Services starting in January 2005. The contract was approved by the Louisiana Public Service Commission in November 2004. In August 2004, Cleco Power issued a solicitation for proposals for up to 1,000 MW of capacity and energy to replace existing contracts and to accommodate load growth, as well as up to 800 MW to replace older, gas-fired units. A one-year alternate solicitation for up to 645 MW to meet 2006 requirements was issued in January 2005. Cleco Power has been evaluating a range of generation supply options for 2006 and beyond, including sources of long-term purchased power, acquiring additional generation facilities, self-build proposals and reconfiguring certain of its existing generation facilities. Cleco Power may not be able to obtain purchased power or generation facilities on terms comparable to those in its current power purchase agreements or at all. In addition, the Louisiana Public Service Commission may not approve any such supply option or if approved, may not allow Cleco Power to recover part or all of any additional amounts it may pay under new power purchase agreements, in obtaining new generation facilities, in reconfiguring certain of its existing generation facilities or otherwise as a result of the expiration of its existing power purchase agreements, which amounts could be substantial.

          Adverse findings or determinations in regulatory and investigatory proceedings to which we are subject could require the refunding of revenue and could result in the imposition of additional penalties and restrictions on us. Additional lawsuits could be filed relating to activities and transactions reviewed in such proceedings.

          In 2002, we identified certain energy trading activities and other transactions between Cleco Power and some of our Cleco Midstream subsidiaries. These activities consisted primarily of indirect sales of test power by Cleco Evangeline LLC to Cleco Power, other indirect acquisitions of purchased power by Cleco Power from Cleco Marketing & Trading LLC, Cleco Power’s indirect sales of power to Cleco Marketing & Trading LLC, and other transactions between Cleco Power and Cleco Marketing & Trading LLC. We determined that certain of these activities and transactions may have violated the Public Utility Holding Company Act of 1935 as well as various statutes and regulations administered by the Louisiana Public Service Commission and the Federal Energy Regulatory Commission. In July 2003, we entered into the Stipulation and Consent Agreement with the staff of the Federal Energy Regulatory Commission with respect to these activities and transactions. Under the Stipulation and Consent Agreement, we agreed to a revocation of Cleco Marketing & Trading LLC’s market-based rate authority (with the right to reapply for market-based rate authority after one year), to make refunds of $2.1 million to Cleco Power for profits obtained through various affiliate energy marketing and trading transactions between 1999 and 2002, to make payment of a $0.8 million civil penalty to the Federal Energy Regulatory Commission, and to a three-year compliance program, as well as to abide by other restrictions and mandatory plans.

          The Louisiana Public Service Commission initiated formal proceedings, which became part of Cleco Power’s fuel audit, to investigate these activities and transactions. A lawsuit was filed in the 27th Judicial District Court, Parish of St. Landry by several Cleco Power customers relating to these activities and transactions. In November 2004, the St. Landry Parish lawsuit was dismissed with prejudice and all claims related to the lawsuit were released. There can be no assurance that additional lawsuits will not be filed by Cleco Power customers relating to the activities and transactions investigated in the Federal Energy Regulatory Commission investigation and the fuel audit.

          Cleco is subject to substantial government regulation; compliance with current and future regulatory requirements may result in substantial costs; the expiration of Cleco Power’s rate stabilization plan, as extended through September 2005, could result in a reduction in Cleco Power’s regulated rate of return, which is the primary basis for its earnings and cash flows.

          We are subject to substantial regulation from federal and state regulatory agencies. We are required to comply with numerous laws and regulations and to obtain numerous authorizations, permits, approvals and certificates from governmental agencies. These agencies regulate various aspects of our business, including customer rates, service regulations, system reliability, retail service territories, generation plant operations and accounting policies and practices. We cannot predict the impact on our operating results from future regulatory activities of these agencies. Compliance with current and future regulatory requirements and procurement of necessary approvals, permits and certificates may result in substantial costs to us.

          Cleco Power’s retail power rates for residential, commercial and industrial customers and other retail sales are regulated by the Louisiana Public Service Commission. Under a rate stabilization plan approved by the Louisiana Public Service Commission, Cleco Power is allowed to realize a regulatory return on equity of up to 12.625%, with returns above that level being refunded to customers in the form of billing credits. In March 2004, the Louisiana Public Service Commission granted a one-year extension of the expiration of the plan, without modification, from September 2004 to September 2005. Cleco Power currently has ongoing both short- and long-term generation supply requests for proposals that will have a direct impact on Cleco Power’s decision to seek an extension of the rate stabilization plan. Based on the timeline for the request for proposals, management anticipates making such a decision by June 2005 or earlier. Possible rate stabilization plan options include seeking a short-term extension, combining an extension request with a generation certificate of public convenience and necessity application, seeking a new rate case, or allowing the current plan to expire and continue under current rates until the Louisiana Public Service Commission orders a review of Cleco Power’s rates. Upon expiration of the current rate stabilization plan, the Louisiana Public Service Commission could

reduce Cleco Power’s regulated rate of return in establishing a new plan or modifying the existing plan, which would reduce our base revenue and profitability.

          In January 2005, the Louisiana Public Service Commission opened a docket to explore and study the rate structures of all classes of electric customers after receiving complaints that Louisiana’s utility rates are too high to attract new business to the state. A class-by-class review of rates paid by residential, commercial, and industrial customers may be conducted in an effort to determine if one class of customers is subsidizing rates for another. The timing of this review by the Louisiana Public Service Commission has not been determined and its exploratory nature makes the potential impact from such a review unknown at this time.

          On May 25, 2005, the Federal Energy Regulatory Commission issued an order stating that it will institute a proceeding under section 206 of the Federal Power Act to determine whether Cleco Power, Cleco Evangeline LLC, Perryville Energy Partners and Acadia Power Partners may continue to charge market-based rates for wholesale power in specified geographic areas. The Federal Energy Regulatory Commission authorizes wholesale power sales at market-based rates if, among other things, the seller and its affiliates do not have, or have adequately mitigated, market power in generation. The agency states in its order that the section 206 proceeding will be instituted because a market power analysis filed by us indicates that certain “screens” implemented by the agency were not satisfied in specified geographic markets, creating a rebuttable presumption that Cleco Power, Cleco Evangeline LLC, Perryville Energy Partners and Acadia Power Partners may possess market power. The order, among other things, directs that within 60 days we must (i) file a delivered price test analysis, which is a detailed economic evaluation of market power, (ii) file a mitigation proposal to eliminate our ability to exercise market power or (iii) inform the agency that we will adopt cost-based rates for power sales within Cleco Power’s control area. As a result of the section 206 proceeding, we could be subject to refunds on wholesale sales as of 60 days following the publishing of the agency’s order in the Federal Register, which could be material. Moreover, the implementation of cost-based rates or operational changes in connection with any mitigation proposal could cause a material reduction in our revenues from wholesale power sales, although we believe that the application of cost-based rates may only be ordered on a prospective basis.

          The nonperformance by counterparties under agreements by which Cleco Power obtains a significant portion of its purchased power could result in an increase in the price at which we provide that power, and the Louisiana Public Service Commission may not allow Cleco Power to recover part or all of any additional amounts it may pay to obtain replacement power.

          If either Calpine Energy Services or Williams Power Company fails to provide power to Cleco Power in accordance with their power purchase agreements, Cleco Power would likely have to obtain replacement power at then-prevailing market prices to meet its customers’ demands. The power market can be volatile, and the prices at which Cleco Power would obtain replacement power could be higher than the prices it currently pays under the power purchase agreements. The Louisiana Public Service Commission may not allow Cleco Power to recover, through an increase in rates or through its fuel adjustment clause, part or all of any additional amounts it may pay in order to obtain replacement power.

          Our costs of compliance with environmental laws, regulations and permits are significant and the cost of compliance with new environmental laws, regulations and permits could be significant and reduce our profitability.

          Our businesses are subject to extensive environmental regulation by federal, state and local authorities. We are required to comply with numerous environmental laws and regulations, and to obtain and to comply with numerous governmental permits, in operating our facilities. In addition, existing environmental laws, regulations and permits could be revised or reinterpreted, new laws and regulations could be adopted or become applicable to us or our facilities, and future changes in environmental laws and regulations could occur, including potential regulatory and enforcement developments related to air emissions. We may incur significant additional costs to comply with these revisions, reinterpretations and requirements. If we fail to comply with these revisions, reinterpretations and requirements, we could be subject to civil or criminal liabilities and fines.

          In October 2003, the Texas Commission on Environmental Quality notified Cleco Power that it had been identified as a potentially responsible party for the San Angelo Electric Service Company facility in San

Angelo, Texas. The facility operated as a transformer repair and scrapping facility from the 1930s until 2003, and both soil and groundwater contamination exist at the site and in surrounding areas. Based on initial available information, Cleco Power accrued a minimal amount for its potential liability for the site in November 2003. In September 2004, Cleco Power received documentation indicating that Cleco Power may have sent a greater number of transformers to San Angelo Electric Service Company for repair, refurbishing and/or recycling than previously believed. The investigation of San Angelo Electric Service Company’s historical records is still ongoing. The results of the continued investigation could show that Cleco Power’s dealings with San Angelo Electric Service Company were more extensive than current documentation indicates. Additional work is being conducted by a group of potentially responsible parties, including Cleco Power, at the direction of the Texas Commission on Environmental Quality, to maintain the site and to identify additional potentially responsible parties. It is likely that Cleco Power together with other potentially responsible parties will be required to contribute to the past and future cost of the investigation and remediation of the site. The ultimate cost of remediation of the site, Cleco Power’s share of such cost and the timing of any accrual that Cleco Power may be required to make in connection with this matter cannot be estimated at this time. It is possible, however, that Cleco’s share of such cost could be significant and could have a material adverse impact on its results of operations, financial condition and cash flow.

          In February 2005, Cleco Power received notices that the Environmental Protection Agency is requesting certain information relating to the Rodemacher and Dolet Hills power plants as authorized by Section 114 of the Clean Air Act. The apparent purpose of the investigation is to determine whether Cleco Power has complied with applicable new source review regulations of the Environmental Protection Agency and in connection with capital expenditures, modifications, or operational changes Cleco Power has made at these facilities. These regulations, require electric utilities to undergo pre-construction review for environmental controls if new generating units are built and also apply if existing units are modified by making “non-routine” physical or operational changes that result in a significant increase in emissions of a regulated pollutant. In addition, they regulate air emissions by many types of industrial facilities. Cleco Power has completed its response to the initial data request. It is unknown at this time when the Environmental Protection Agency will take further action, if any, as a result of the information to be provided by Cleco Power and if any such action would have a material adverse impact on Cleco’s financial condition, results of operations, or cash flows.

          We may incur additional costs or delays in power plant construction and may not be able to recover their investment.

          Cleco Power currently has an ongoing long-term generation supply request for proposals that includes, among other proposals, various self-build proposals. It is possible that one or more of the self-build options is chosen in the request for proposals process. If selected in the request for proposals process, the completion of any of these options without delays or cost overruns is subject to substantial risks, including:

If any of the self-build options are selected and not completed on schedule, Cleco Power may need to obtain replacement power at then-prevailing market prices to meet its customers’ demands. The Louisiana Public Service Commission may not allow Cleco Power to recover, through an increase in rates or through its fuel adjustment clause, part or all of any amounts it may pay in order to obtain this replacement power.

          If Cleco Power is unable to complete the development or construction of one of the self-build options if selected in the request for proposals process, or if it decides to delay or cancel construction of one of the self-build options, it may not be able to recover its investment in that facility. In addition, construction delays and contractor performance shortfalls can result in the loss of revenues and may, in turn, adversely affect the results of operations and financial position of Cleco Power and us. Furthermore, if construction projects are not completed according to specification, Cleco Power may incur liabilities and suffer reduced plant efficiency, higher operating costs and reduced earnings.

          Our generation facilities are subject to unplanned outages and significant maintenance requirements.

          The operation of power generation facilities involves many risks, including the risk of breakdown or failure of equipment, fuel interruption and performance below expected levels of output or efficiency. If our facilities, or the facilities of other parties upon which we depend, operate below expectations, we may lose revenues, have increased expenses or fail to receive the amount of power for which we have contracted.

          Some of our facilities were originally constructed many years ago. Older equipment, even if maintained in accordance with good engineering practices, may require significant capital expenditures to operate at peak efficiency or availability. If we underestimate required maintenance expenditures, or are unable to make required capital expenditures due to liquidity constraints, we risk incurring more frequent unplanned outages, higher than anticipated maintenance expenditures, increased operation at higher cost of some of our less efficient generation facilities and the need to purchase power from third parties to meet our supply obligations.

          We are a holding company, and our ability to meet our debt obligations and pay dividends on our common stock is dependent on the earnings of our subsidiaries and the distribution of such earnings to us in the form of dividends or distributions.

          We are a holding company and we conduct our operations primarily through our subsidiaries. Substantially all of our consolidated assets are held by our subsidiaries. Accordingly, our ability to meet our debt obligations and pay dividends on our common stock is largely dependent upon the earnings of these subsidiaries and the distribution or other payment of such earnings to us. The subsidiaries are separate and distinct legal entities and have no obligation to pay any amounts due on our debt or to make any funds available for such payment. In addition, our subsidiaries’ ability to make dividend payments or other distributions to us may be restricted by their obligations to holders of their outstanding securities and to creditors, the availability of earnings and the needs of their businesses. Moreover, Cleco Power, our largest subsidiary, is subject to regulation by the Louisiana Public Service Commission, which may impose limits on the amount of dividends that Cleco Power may pay us.

          A downgrade in our credit rating could result in an increase in our borrowing costs and a decrease in our pool of potential investors and funding sources.

          While the senior unsecured debt ratings of Cleco Corporation and Cleco Power are “investment grade,” such ratings have been downgraded or put on negative watch by Standard & Poor’s and Moody’s as recently as March 2003. We cannot assure you that our debt ratings will remain in effect for any given period of time or that one or more of our debt ratings will not be lowered or withdrawn entirely by a rating agency. We note that our credit ratings are not recommendations to buy, sell or hold securities. Each rating should be evaluated independently of any other rating. If Moody’s or Standard & Poor’s were to downgrade Cleco Corporation’s long-term rating or Cleco Power’s long-term rating, particularly below investment grade, the value of any of our debt securities would likely be adversely affected and our borrowing costs would increase, which would diminish our financial results. In addition, we would likely be required to pay higher interest rates in future debt financings, and our pool of potential investors and funding sources could decrease.

          You assume the risk that the market value of our common stock may decline.

          The stock market has experienced significant price and trading volume fluctuations, and the market prices of companies in our industry have been particularly volatile. It is impossible to predict whether the price of our common stock will rise or fall. Trading prices of our common stock will be influenced by our operating results and prospects and by economic, financial and other factors. In addition, general market conditions, including the level of, and fluctuations in, the trading prices of stocks generally, and sales of substantial amounts of common stock by us in the market after any offering of common stock offered by this prospectus, or the perception that such sales could occur, could affect the price of our common stock.

          Provisions of Louisiana law and of our amended and restated articles of incorporation and bylaws could restrict the acquisition of us, the acquisition of control or the removal of our incumbent officers and directors and could affect the market price of our common stock.

          Some provisions of Louisiana law and our amended and restated articles of incorporation and bylaws could make an acquisition of us by means of a tender offer, an acquisition of control of us by means of a proxy contest or otherwise or removal of our incumbent officers and directors more difficult. In addition, we have a classified board of directors, our articles of incorporation require a supermajority vote for the sale, lease or disposition of all or any or our assets and Louisiana law and our bylaws require board and supermajority shareholder approval of mergers, consolidations or share exchanges with an interested shareholder. These provisions could delay or prevent an acquisition of us that an investor might consider to be in his or her best interest, including attempts that might result in a premium over the market price for our common stock. Please read “Description of Capital Stock — Anti-Takeover Provisions” beginning on page 30 for a more detailed discussion of these provisions.

Use of Proceeds

          Unless we inform you otherwise in the prospectus supplement, we anticipate using net proceeds from the sale of the securities offered by this prospectus for general corporate purposes. These purposes may include, but are not limited to:

Description of Our Debt Securities

          The debt securities offered by this prospectus will be either senior debt securities or subordinated debt securities. We will issue senior debt securities under a senior indenture dated as of May 1, 2000, as amended or supplemented from time to time, between us and J.P. Morgan Trust Company, National Association, as trustee. We will issue subordinated debt securities under an indenture we will enter into with the trustee named in the applicable prospectus supplement. We refer to the senior indenture and the subordinated indenture in this prospectus collectively as the “indentures.” We have filed the forms of the indentures with the Securities and Exchange Commission as exhibits to the registration statement covering the debt securities offered by this prospectus. We have summarized selected provisions of the indentures and the debt securities below. This summary is qualified in its entirety by reference to the indentures.

          We may issue debt securities from time to time in one or more series under the indentures. Our debt securities may be convertible into or exchangeable for shares of our common stock or preferred stock. We will describe the particular terms of each series of debt securities we offer in a supplement to this prospectus. You should carefully read the summary below, the applicable prospectus supplement and the provisions of the relevant indenture that may be important to you before investing in our debt securities.

          The provisions of each of the indentures are substantially identical in substance, except that the subordinated indenture provides for the subordination of the subordinated debt securities. We describe the subordination provisions of the subordinated indenture in the “Subordination Under the Subordinated Indenture” section of this prospectus. We have included cross-references in the summary below to refer you to the section numbers of the indentures we are describing. The section numbers are the same for both of the indentures, unless we state otherwise.

          We may issue debt securities in separate series from time to time under each of the indentures. The total principal amount of debt securities that may be issued under the indentures is unlimited. We may limit the maximum total principal amount for the debt securities of any series. However, any limit may be increased by resolution of our board of directors. (Section 301) We will establish the terms of each series of debt securities, which may not be inconsistent with the related indenture, in a supplemental indenture or a board resolution.

Ranking

          The senior debt securities will rank equally with all of our other unsecured and unsubordinated indebtedness. As of March 31, 2005, Cleco Corporation had an aggregate of $200.0 million of unsecured and unsubordinated indebtedness that would rank equal with the senior debt securities. The subordinated debt securities will rank junior and be subordinate to all of our senior indebtedness as we describe in the “Subordination Under the Subordinated Indenture” section of this prospectus. As of March 31, 2005, Cleco Corporation had an aggregate of $200.0 million of senior indebtedness to which the subordinated debt securities

would rank junior and be subordinated. Both the senior debt securities and the subordinated debt securities will be effectively subordinated to creditors of our subsidiaries. As of March 31, 2005, Cleco Corporation and its subsidiaries had an aggregate of $1.02 billion of indebtedness (including $420.0 million of indebtedness of Perryville Energy Partners and Cleco Evangeline LLC, which subsidiaries have been deconsolidated from Cleco Corporation’s consolidated financial statements in accordance with generally accepted accounting principles), of which $820.2 million is owed by subsidiaries (including $420.0 million of indebtedness of Perryville Energy Partners and Cleco Evangeline LLC) and therefore effectively senior to both the senior debt securities and the subordinated debt securities. Neither indenture restricts the amount of additional indebtedness that we or our subsidiaries may incur.

          Since we are a holding company, our ability to pay debt service on our debt securities is dependent upon the cash flows of our subsidiaries and the ability of our subsidiaries to pay dividends and make debt service payments to us. Certain of our subsidiaries have contractual restrictions on the amount of dividends that they may pay us. In addition, Cleco Power, our largest subsidiary, is subject to regulation by the Louisiana Public Service Commission, which may impose limits on the amount of dividends that Cleco Power may pay us.

The Terms of the Debt Securities

          We will describe the specific terms of the series of debt securities being offered in a supplement to this prospectus. These terms will include some or all of the following:

          We may sell the debt securities, including original issue discount securities, at a substantial discount below their stated principal amount. If there are any special United States federal income tax considerations applicable to debt securities we sell at an original discount, we will describe them in the prospectus supplement. In addition, we will describe in the prospectus supplement any special United States federal income tax considerations and any other special considerations for any debt securities we sell which are denominated in a currency or currency unit other than $US.

Form, Exchange and Transfer of the Debt Securities

          We will issue the debt securities in registered form, without coupons. Unless we inform you otherwise in the prospectus supplement, we will only issue debt securities in denominations of integral multiples of $1,000. (Section 302)

          Holders will generally be able to exchange debt securities for other debt securities of the same series with the same total principal amount and the same terms but in different authorized denominations. (Section 305)

          Holders may present debt securities for exchange or for registration of transfer at the office of the security registrar or at the office of any transfer agent we designate for that purpose. The security registrar or designated transfer agent will exchange or transfer the debt securities if it is satisfied with the documents of title and identity of the person making the request. We will not charge a service charge for any exchange or registration of transfer of debt securities. However, we may require payment of a sum sufficient to cover any tax or other governmental charge payable for the registration of transfer or exchange. Unless we inform you otherwise in the prospectus supplement, we will appoint the trustee as security registrar. We will identify any transfer agent in addition to the security registrar in the prospectus supplement. (Section 305) At any time we may:

However, we are required to maintain a transfer agent in each place of payment for the debt securities at all times. (Sections 305 and 1002)

          In the event we elect to redeem a series of debt securities, neither we nor the applicable trustee will be required to register the transfer or exchange of any debt security of that series:

Global Securities

          Unless we inform you otherwise in the prospectus supplement, some or all of the debt securities of any series may be represented, in whole or in part, by one or more global securities. The global securities will have a total principal amount equal to the debt securities they represent. Unless we inform you otherwise in the prospectus supplement, each global security representing debt securities will be deposited with, or on behalf of, The Depository Trust Company, referred to as “DTC,” or any other successor depository we may appoint. We refer to DTC or the other depository in this prospectus as the “depositary.” Each global security will be registered in the name of the depositary or its nominee. Each global security will bear a legend referring to the restrictions on exchange and registration of transfer of global securities that we describe below and any other matters required by the relevant indenture. Unless we inform you otherwise in the prospectus supplement, we will not issue debt securities in definitive form.

          Global securities may not be exchanged, in whole or in part, for debt securities registered, and no transfer of a global security, in whole or in part, may be registered in the name of any person other than the depositary for the global security or any nominee of the depositary unless:

All debt securities issued in exchange for a global security or any portion of a global security will be registered in the names directed by the depositary. (Sections 204 and 305)

Regarding DTC

          DTC is:

DTC holds securities that its participants deposit with DTC. DTC also facilitates the settlement among participants of securities transactions, such as transfers and pledges, in deposited securities through electronic computerized book-entry changes in participants’ accounts, thereby eliminating the need for physical movement of securities certificates. Direct participants include:

DTC is owned by a number of direct participants and by The New York Stock Exchange, Inc., the American Stock Exchange LLC, and the National Association of Securities Dealers, Inc. Access to DTC’s book-entry system is also available to others, such as securities brokers and dealers, banks and trust companies that clear through or maintain a custodial relationship with a direct participant, either directly or indirectly, referred to as indirect participants. The rules applicable to DTC and its participants are on file with the Securities and Exchange Commission.

          Upon our issuance of debt securities represented by a global security, purchases of debt securities under the DTC system must be made by or through direct participants, which will receive a credit for the debt securities on DTC’s records. The ownership interest of each actual purchaser of each debt security, referred to as a beneficial owner, is in turn to be recorded on the direct and indirect participants’ records. Beneficial owners will not receive written confirmation from DTC of their purchase. However, beneficial owners are expected to receive written confirmations providing details of the transaction, as well as periodic statements of their holdings, from the direct or indirect participant through which the beneficial owner entered into the transaction. Transfers of ownership interests in the debt securities are to be accomplished by entries made on the books of participants acting on behalf of beneficial owners. Beneficial owners will not receive certificates representing their ownership interests in debt securities, except in the event that use of the book-entry system for the debt securities is discontinued. The laws of some states require that certain purchasers of securities take physical delivery of such securities in definitive form. Such laws may impair the ability to transfer beneficial interests in a global security.

          So long as the depositary for the global security, or its nominee, is the registered owner of the global security, the depositary or its nominee, as the case may be, will be considered the sole owner or holder of the debt securities represented by the global security for all purposes under the indentures. Except as described above, beneficial owners will not:

          To facilitate subsequent transfers, all debt securities deposited by participants with DTC are registered in the name of DTC’s partnership nominee, Cede & Co. The deposit of debt securities with DTC and their registration in the name of Cede & Co. effect no change in beneficial ownership. DTC has no knowledge of the actual beneficial owners of the debt securities. DTC’s records reflect only the identity of the direct participants to whose accounts the debt securities are credited, which may or may not be the beneficial owners. The participants will remain responsible for keeping account of their holdings on behalf of their customers. Conveyance of notices and other communications by DTC to direct participants, by direct participants to indirect participants, and by direct participants and indirect participants to beneficial owners will be governed by arrangements among them, subject to any statutory or regulatory requirements as may be in effect from time to time.

          Neither DTC nor Cede & Co. will consent or vote with respect to debt securities. Under its usual procedures, DTC mails an omnibus proxy to us as soon as possible after the record date. The omnibus proxy assigns Cede & Co.’s consenting or voting rights to those direct participants to whose accounts the debt securities are credited on the record date, identified in a listing attached to the omnibus proxy.

          We will make payments of principal, premium, if any, and interest on the debt securities represented by the global security registered in the name of the depositary or its nominee through the trustee under the relevant indenture or a paying agent, which may also be the trustee under the relevant indenture, to the depositary or its nominee, as the case may be, as the registered owner of the global security. Neither we, the trustees, nor the paying agent will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests of the global security or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests.

          We have been advised that DTC will credit direct participants’ accounts on the payable date in accordance with their respective holdings shown on DTC’s records unless DTC has reason to believe that it will not receive payment on the payable date. Payments by participants to beneficial owners will be governed by standing instructions and customary practices, as in the case with securities held for the accounts of customers in bearer form or registered in “street name,” and will be the responsibility of such participant and not of DTC, the paying agent, or us, subject to any statutory or regulatory requirements as may be in effect from time to time. Payment of principal, premium, if any, and interest to DTC is either our responsibility or the responsibility of the paying agent. Disbursement of these payments to direct participants is the responsibility of DTC. Disbursement of these payments to the beneficial owners is the responsibility of direct and indirect participants.

          We cannot assure you that DTC will distribute payments on the debt securities made to DTC or its nominee as the registered owner or any redemption or other notices to the participants, or that the participants or others will distribute the payments or notices to the beneficial owners, or that they will do so on a timely basis, or that DTC will serve and act in the manner described in this prospectus. Beneficial owners should make appropriate arrangements with their broker or dealer regarding distribution of information regarding the debt securities that may be transmitted by or through DTC.

          According to DTC, the foregoing information with respect to DTC has been provided to the industry for informational purposes only and is not intended to serve as a representation, warranty, or contract modification of any kind.

          We have obtained the information in this section concerning DTC and the DTC’s book-entry system from sources that we believe are reliable.

Payment and Paying Agents

          Unless we inform you otherwise in the prospectus supplement, we will pay interest on the debt securities to the persons in whose names the debt securities are registered at the close of business on the regular record date for each interest payment. However, unless we inform you otherwise in the prospectus supplement, we will pay the interest payable on the debt securities at their stated maturity to the persons we pay the principal amount of the debt securities. The initial payment of interest on any series of debt securities issued between a regular record date and the related interest payment date will be payable in the manner provided by the terms of the series, which we will describe in the prospectus supplement. (Section 307)

          Unless we inform you otherwise in the prospectus supplement, we will pay principal, premium, if any, and interest on the debt securities at the offices of the paying agents we designate. However, except in the case of a global security, we may pay interest by:

We will designate the applicable trustee as the sole paying agent for the debt securities issued under the relevant indenture unless we inform you otherwise in the prospectus supplement. If we initially designate any other paying agents for a series of debt securities, we will identify them in the prospectus supplement. At any time, we may designate additional paying agents or rescind the designation of any paying agents. However, we are required to maintain a paying agent in each place of payment for the debt securities at all times. (Sections 307 and 1002)

          Any money deposited with the applicable trustee or any paying agent for the payment of principal, premium, if any, and interest on the debt securities that remains unclaimed for two years after the date the payments became due, may be repaid to us upon our request. After we have been repaid, holders entitled to those payments may only look to us for payment as our unsecured general creditors. The trustees and any paying agents will not be liable for those payments after we have been repaid. (Section 1003)

Covenants

          We will describe any restrictive covenants for any series of debt securities in the prospectus supplement.

Consolidation, Merger and Sale of Assets

          Unless we inform you otherwise in the prospectus supplement, we may not consolidate with or merge into, or convey, transfer or lease our properties and assets substantially as an entirety, to any person, referred to as a “successor person,” unless:

Absence of Event Risk Protections

          Unless we inform you otherwise in the prospectus supplement, the indenture for a series of debt securities will not contain provisions permitting the holders of our debt securities to require prepayment in the event of a change in control of us, or in the event we enter into one or more highly leveraged transactions, regardless of whether a rating decline results therefrom, or in the event we dispose of one or more of our business units, nor are any such events deemed to be Events of Default under the terms of the indentures.

Events of Default

          Unless the context clearly indicates otherwise, we use the terms “indenture” and “trustee” in this subsection to mean the relevant indenture and the applicable trustee with respect to any series of debt securities we may offer.

          Unless we inform you otherwise in the prospectus supplement, each of the following will be an event of default under the indenture for a series of debt securities:

provided, however, that no event described in number four and number six above will be an event of default until an officer of the trustee, assigned to and working in the trustee’s corporate trust department, has actual knowledge of the event or until the trustee receives written notice of the event at its corporate trust office, and the notice refers to the debt securities generally, us or the indenture. (Section 501)

          If the principal, premium, if any, or interest on any series of debt securities is payable in a currency other than $US and the currency is not available to us for making payments due to the imposition of exchange controls or other circumstances beyond our control, we may satisfy our obligations to holders of the debt securities by making payment in $US in an amount equal to the $US equivalent of the amount payable in the other currency. This amount will be determined by the trustee by reference to the noon buying rate in The City of New York for cable transfers for the other currency, referred to as the “exchange rate,” as reported or otherwise made available by the Federal Reserve Bank of New York on the date of the payment, or, if the exchange rate is not then available, on the basis of the most recently available exchange rate. Any payment made in $US under these circumstances will not be an event of default under the indenture. (Section 501)

          If an event of default for a series of debt securities occurs and is continuing, either the trustee or the holders of at least 33% in principal amount of the outstanding debt securities of that series may declare the principal amount of the debt securities of that series due and immediately payable. In order to declare the principal amount of the series of debt securities due and immediately payable, the trustee or the holders must deliver a notice that satisfies the requirements of the indenture. Upon a declaration by the trustee or the holders, we will be obligated to pay the principal amount of the series of debt securities.

          This right does not apply if:

If any of these events of default occur and is continuing, either the trustee or holders of at least 33% in principal amount of all of the debt securities then outstanding, treated as one class, may declare the principal amount of all of the debt securities then outstanding to be due and payable immediately. In order to declare the principal amount of the debt securities due and immediately payable, the trustee or the holders must deliver a notice that satisfies the requirements of the indenture. Upon a declaration by the trustee or the holders, we will be obligated to pay the principal amount of the debt securities.

          After any declaration of acceleration of a series of debt securities, but before a judgment or decree for payment, the holders of a majority in principal amount of the outstanding debt securities of that series may, under certain circumstances, rescind and annul the declaration of acceleration if all events of default, other than the non-payment of principal have been cured or waived as provided in the indenture. (Section 502) For information as to waiver of defaults, please refer to the “Modification and Waiver” section below.

          If an event of default occurs and is continuing, the trustee will generally have no obligation to exercise any of its rights or powers under the indenture at the request or direction of any of the holders, unless the holders offer reasonable indemnity to the trustee. (Section 603) The holders of a majority in principal amount of the outstanding debt securities of any series will generally have the right to direct the time, method and place of conducting any proceeding for any remedy available to the trustee or exercising any trust or power conferred on the trustee for the debt securities of that series, provided that:

          A holder of a debt security of any series may only pursue a remedy under the indenture if:

However, these limitations do not apply to a suit by a holder of a debt security demanding payment of the principal, premium, if any, or interest on a debt security on or after the date the payment is due. (Section 508)

          We will be required to furnish to the trustee annually a statement by some of our officers regarding our performance or observance of any of the terms of the indenture and, specifying all of our known defaults, if any. (Section 1004)

Modification and Waiver

          Unless the context clearly indicates otherwise, we use the terms “indenture” and “trustee” in this subsection to mean the relevant indenture and the applicable trustee with respect to any series of debt securities we may offer.

          We may enter into one or more supplemental indentures with the trustee without the consent of the holders of the debt securities of a particular series in order to:

          We may enter into one or more supplemental indentures with the trustee in order to add to, change or eliminate provisions of the indenture or to modify the rights of the holders of one or more series of debt securities if we obtain the consent of the holders of a majority in principal amount of the outstanding debt securities of each series affected by the supplemental indenture, treated as one class. However, without the consent of the holders of each outstanding debt security affected by the supplemental indenture, we may not enter into a supplemental indenture that:

          Holders of a majority in principal amount of the outstanding debt securities of any series may waive past defaults or compliance with restrictive provisions of the indenture. However, the consent of holders of each outstanding debt security of a series is required to:

          In order to determine whether the holders of the requisite principal amount of the outstanding debt securities have taken an action under the indenture as of a specified date:

Some debt securities, including those for whose payment or redemption money has been deposited or set aside in trust for the holders and those that have been fully defeased upon the deposit of money in trust for the holders sufficient to pay the principal, premium, if any, and interest on the debt securities on their respective stated maturities, will not be deemed to be outstanding. (Section 101)

          We will generally be entitled to set any day as a record date for determining the holders of outstanding debt securities of any series entitled to give or take any direction, notice, consent, waiver or other action under the indenture. In limited circumstances, the trustee will be entitled to set a record date for action by holders of

outstanding debt securities. If a record date is set for any action to be taken by holders of a particular series, the action may be taken only by persons who are holders of outstanding debt securities of that series on the record date. To be effective, the action must be taken by holders of the requisite principal amount of the debt securities within a specified period following the record date. For any particular record date, this period will be 180 days or such shorter period as we may specify, or the trustee may specify, if it set the record date. This period may be shortened or lengthened by not more than 180 days. (Section 104)

Subordination Under the Subordinated Indenture

          We have defined some of the terms we use in this subsection at the end of this subsection.

          The subordinated debt securities issued under the subordinated indenture will be unsecured and junior in right of payment to all of our senior indebtedness. This means we will not be permitted to make a payment on the subordinated debt securities if:

          If our assets are distributed to our creditors upon our dissolution, winding-up or liquidation, whether voluntarily or involuntarily or in bankruptcy, insolvency, receivership, reorganization or other similar proceedings, all principal, premium, if any, interest and any other amounts due or to become due on all of our senior indebtedness must be paid in full before the holders of the subordinated debt securities are entitled to receive or retain any payment.

          “Debt” in the subordinated indenture means, with respect to any person at any date of determination, without duplication:

          “Senior indebtedness” in the subordinated indenture means the principal, premium, if any, and interest on and all other amounts due in connection with all of our debt, whether created, incurred or assumed before, on or after the date of the subordinated indenture. However, senior indebtedness does not include:

          The subordinated indenture does not limit our ability to incur additional indebtedness, including indebtedness that ranks senior in priority of payment to the subordinated debt securities.

Conversion

          Our debt securities may be convertible into or exchangeable for shares of our common stock or preferred stock. The terms on which any debt securities will be convertible into or exchangeable for shares of our common stock or preferred stock will be set forth in the prospectus supplement related to such debt securities.

Defeasance and Covenant Defeasance

          Unless the context clearly indicates otherwise, we use the terms “indenture” and “trustee” in this subsection to mean the relevant indenture and the applicable trustee with respect to any series of debt securities we may offer.

          Unless we inform you otherwise in the prospectus supplement, the provisions of the indenture relating to defeasance and discharge of indebtedness, or defeasance of restrictive covenants, will apply to the debt securities of any series. (Section 1401)

          Defeasance and Discharge. We will be discharged from all of our obligations with respect to the debt securities, except for certain obligations to exchange or register the transfer of debt securities, to replace stolen, lost or mutilated debt securities, to maintain paying agencies and to hold moneys for payment in trust, upon the deposit in trust for the benefit of the holders of such debt securities of money or U.S. government obligations, or both, which, through the payment of principal and interest in respect thereof in accordance with their terms, will provide money in an amount sufficient to pay the principal, premium, if any, and interest on the debt securities on the respective stated maturities in accordance with the terms of the indenture and the debt securities. Such defeasance or discharge may occur only if, among other things, we have delivered to the trustee an opinion of counsel to the effect that we have received from, or there has been published by, the United States Internal Revenue Service a ruling, or there has been a change in tax law, in either case to the effect that holders of the debt securities will not recognize gain or loss for federal income tax purposes as a result of such deposit, defeasance and discharge and will be subject to federal income tax on the same amount, in the same manner and at the same times as would have been the case if such deposit, defeasance and discharge were not to occur. (Sections 1402 and 1404)

          Defeasance of Certain Covenants. In certain circumstances, we may omit to comply with specified restrictive covenants, including those described under “Consolidation, Merger and Sale of Assets” and any that we may describe in the prospectus supplement, and in those circumstances the occurrence of certain events of default, which are described in number four above, with respect to such restrictive covenants, under “Events of Default” and any that may be described in the prospectus supplement, will be deemed not to be or result in an event of default, in each case with respect to the debt securities. We, in order to exercise such option, will be required to deposit, in trust for the benefit of the holders of the debt securities, money or U.S. government obligations, or both, which, through the payment of principal and interest in respect thereof in accordance with their terms, will provide money in an amount sufficient to pay the principal, premium, if any, and interest on the debt securities on the respective stated maturities in accordance with the terms of the indenture and the debt securities. We will also be required, among other things, to deliver to the trustee an opinion of counsel to the effect that holders of the debt securities will not recognize gain or loss for federal income tax purposes as a result of such deposit and defeasance of certain obligations and will be subject to federal income tax on the same amount, in the same manner and at the same times as would have been the case if such deposit and defeasance were not to occur. In the event we exercise this option with respect to any debt securities and the debt securities were declared due and payable because of the occurrence of any event of default, the amount of money and U.S. government obligations so deposited in trust would be sufficient to pay amounts due on the debt securities at the time of their respective stated maturities, but might not be sufficient to pay amounts due on such debt securities upon any acceleration resulting from the event of default. In such case, we would remain liable for those payments. (Sections 1403 and 1404)

Notices

          Holders will receive notices by mail at their addresses as they appear in the security register. (Sections 101 and 106)

Title

          We may treat the person in whose name a debt security is registered on the applicable record date as the owner of the debt security for all purposes, whether or not it is overdue. (Section 309)

Governing Law

          New York law will govern the indentures and the debt securities. (Section 112)

Regarding the Trustee

          J.P. Morgan Trust Company, National Association or an affiliate thereof acts as (a) trustee, collateral agent and securities intermediary under certain senior secured bonds issued by Cleco Evangeline LLC and (b) trustee under certain first mortgage bonds issued by Cleco Power. J.P. Morgan Trust Company or an affiliate thereof also is a lender and syndication agent under Cleco Corporation’s five-year revolving credit facility and Cleco Power’s five-year revolving credit facility. In addition, J.P. Morgan Trust Company and its affiliates may from time to time act as a depositary for funds of, make loans to, and perform other services for Cleco Corporation and its affiliates in the ordinary course of business.

Description of Capital Stock

          We have summarized selected aspects of our capital stock below. For a complete description, you should refer to our amended and restated articles of incorporation, bylaws and the Rights Agreement, dated as of July 28, 2000, between us and Equiserve Trust Company, as rights agent, all of which are exhibits to the registration statement of which this prospectus is part.

          Our authorized capital stock consists of:

          As of March 31, 2005, 49,816,068 shares of our common stock were outstanding, 226,870 shares of our $100 preferred stock were outstanding and no shares of our $25 preferred stock were outstanding. Our board of directors has reserved for issuance pursuant to our shareholder rights plan a total of 500,000 shares of $25 preferred stock, designated as Series A Participating Preferred Stock. Holders of common stock may purchase shares of our Series A Participating Preferred Stock if the rights associated with their common stock are exercisable and the holders exercise the rights. Please read the “— Shareholder Rights Plan” section below and “Where You Can Find More Information” beginning on page 36.

Common Stock

          Each share of common stock entitles the holder to one vote on all matters submitted to a vote of shareholders, except in the election of directors, in which case holders of common stock have cumulative voting rights. Cumulative voting gives each shareholder the right to multiply the number of votes to which he or she is entitled by the number of directors to be elected and to cast all of those votes for one candidate or distribute them among any two or more candidates. Subject to preferences that may be applicable to any outstanding preferred stock and to restrictive covenants in certain debt instruments of ours, the holders of common stock are entitled to dividends when, as and if declared by the board of directors out of funds legally available for that purpose. If we are liquidated, dissolved or wound up, the holders of common stock will be entitled to a pro rata share in any distribution to shareholders, but only after satisfaction of all of our liabilities and of the prior rights of any outstanding class of our preferred stock.

          The common stock has no preemptive or conversion rights or other subscription rights. There are no redemption or sinking fund provisions applicable to the common stock.

          The common stock is listed on the New York Stock Exchange and trades under the symbol “CNL.”

Preferred Stock

          We have summarized below selected aspects of our $25 preferred stock and $100 preferred stock, which we collectively refer to as the “preferred stock.” We will file the form of the amendment to our articles of incorporation providing for the establishment of a series of preferred stock with the Securities and Exchange Commission before we issue any shares of that series of preferred stock, and you should read the form of amendment for provisions that may be important to you. Subject to specified restrictions in our articles of incorporation relating to our net earnings, which restrictions must be satisfied at the time of issuance, our board of directors can, without action by the shareholders, issue one or more series of the preferred stock. The board can determine for each series the number of shares, designation, dividend rates and other rights, preferences and limitations. In some cases, the issuance of preferred stock could delay or discourage a change in control of us.

          Each share of $100 preferred stock entitles the holder to one vote on all matters submitted to a vote of the shareholders, and each share of $25 preferred stock entitles the holder to one-fourth vote. All shares of preferred stock will rank equally with each other, and no class of stock ranking senior to the preferred stock can be created unless authorized by a vote of holders of two-thirds of the outstanding preferred stock, voting as a class. Cumulative voting rights do not apply to the preferred stock, but holders of preferred stock are entitled to special voting rights with respect to election of directors if we fail to make payments on the preferred stock in specified cases. By action of our board of directors, we may redeem all or any part of any series of outstanding preferred stock. Dividends on the preferred stock will be cumulative.

          The prospectus supplement relating to any series of preferred stock we are offering will include specific terms relating to the offering. These terms will include some or all of the following:

Anti-Takeover Provisions

          Some provisions of Louisiana law and our amended and restated articles of incorporation and bylaws could make the following more difficult:

          These provisions, as well as our shareholder rights plan and our ability to issue preferred stock, are designed to discourage coercive takeover practices and inadequate takeover bids. These provisions are also designed to encourage persons seeking to acquire control of us to first negotiate with our board of directors. We believe that the benefits of increased protection give us the potential ability to negotiate with the proponent of an unfriendly or unsolicited proposal to acquire or restructure us, and that the benefits of this increased protection outweigh the disadvantages of discouraging those proposals, because negotiation of those proposals could result in an improvement of their terms. These provisions could delay or prevent an acquisition of us that a shareholder might consider to be in his or her best interest, including attempts that might result in a premium over the market price for our common stock.

Classified Board of Directors

          Our board of directors is divided into three classes. The directors in each class will serve for a three-year term, with only one class being elected each year by our shareholders. This system of electing and removing directors may discourage a third party from making a tender offer or otherwise attempting to obtain control of us, because it generally makes it more difficult for shareholders to replace a majority of the directors. Subject to special provisions for cumulative voting, holders of 80% of the shares of common stock entitled to vote in the election of directors may remove a director for cause, but shareholders may not remove any director without cause.

Shareholder Meetings

          Our articles of incorporation and bylaws provide that special meetings of shareholders may be called by the chief executive officer or president, a majority of the board of directors, a majority of the executive committee of the board of directors or by shareholders holding 51% of our total voting power. In some cases, shareholders holding specified amounts of preferred stock may also call a special meeting. A majority of the outstanding shares of common stock entitled to vote is a quorum for a shareholder meeting. In general, a majority of votes cast decides a matter brought before a meeting.

Shareholder Proposals and Nominations of Directors

          Shareholders can submit proposals and nominate candidates for our board of directors if the shareholders follow advance notice procedures described in our bylaws.

          To make a proposal or nominate a candidate for our board of directors, a shareholder must submit a timely notice to our secretary. Generally, a shareholder’s proposal must be received at least 120 days prior to the meeting for which the proposal is made. If we give less than 135 days’ notice or prior public disclosure of the meeting, we must receive the proposal no later than 15 days after the day we give notice or make public the date of the meeting. A shareholder’s director nomination must be received at least 180 days before the meeting at which the person is proposed to be nominated. Shareholder proposals or nominations must give specified information about the shareholder and the proposal being made or the director being nominated, as the case may be. Shareholder proposals and director nominations that are late or that do not include the required information may be rejected. This could prevent shareholders from bringing certain matters before a meeting, including making nominations for directors.

Supermajority Vote for Certain Transactions

          Our articles of incorporation provide that we may sell, lease or otherwise dispose of all or any of our assets upon the affirmative vote of two-thirds of all directors. But if such a transaction involves the receipt of shares or securities of another corporation, we may engage in the transaction only upon receiving the affirmative vote of two-thirds of all directors and holders of a majority of our outstanding capital stock. Additionally, unless we redeem all outstanding shares of preferred stock, we may not take any of the following actions without the consent of holders of two-thirds of any outstanding preferred stock:

Interested Shareholder Transactions

          Louisiana law and our bylaws require that mergers, consolidations or share exchanges with a shareholder owning 10% or more of our voting power be recommended by the board and approved by:

          Our bylaws provide that a quorum for purposes of voting on such a transaction consists of 80% of the votes entitled to be cast, unless 80% of the “continuing directors,” as defined in our bylaws, approves the transaction prior to submission of the matter to a shareholder vote.

          Transactions that do not alter the contract rights of our stock or convert our shares and satisfy certain consideration and procedural requirements are exempt from these requirements.

Limitation of Liability of Officers and Directors

          Section 24 of the Louisiana Business Corporation Law authorizes corporations to limit or eliminate the personal liability of officers and directors to corporations and their shareholders for monetary damages for breach of officers’ and directors’ fiduciary duties, except for:

          Our articles of incorporation limit the liability of our officers and directors to us and our shareholders to the fullest extent permitted by Louisiana law. The inclusion of these provision in our articles of incorporation may reduce the likelihood of derivative litigation against our officers and directors, and may discourage or deter shareholders or management from bringing a lawsuit against our officers and directors for breach of their duty of care, even though such an action, if successful, might have otherwise benefited us and our shareholders. Our bylaws provide indemnification to our officers and directors and certain other persons.

Other Provisions

          Except for specified cases in which our board of directors may amend our articles of incorporation, amendment of our articles of incorporation requires the affirmative vote, at a meeting, of holders of the majority of our outstanding capital stock. Additionally, our bylaws provide that amendments to our articles of incorporation that affect any of the following items will not be effective until at least one year after the adoption of the amendment by the shareholders:

          Our bylaws may be amended by the affirmative vote of a majority of the board of directors, subject to the power of the shareholders to amend the bylaws upon the affirmative vote of 80% of all shares of our stock entitled to vote.

          Shareholder proposals to amend our articles of incorporation or bylaws must be received by the secretary at least 180 days before the meeting at which the proposal is to be considered and must contain specified information. These proposals may be rejected if not made in time or if they fail to include the required information.

Transfer Agent and Registrar

          EquiServe First Chicago Trust Division, Jersey City, New Jersey, is our transfer agent and registrar.

Shareholder Rights Plan

          We have a shareholder rights plan under which one preferred stock purchase right is attached to each outstanding share of our common stock. The rights become exercisable under specified circumstances, including any person or group (an “acquiring person”) becoming the beneficial owner of 15% or more of our outstanding common stock, subject to specified exceptions. Each right entitles the registered holder to purchase from us one one-hundredth of a share of Series A Participating Preferred Stock, par value $25 per share, at an exercise price of $125, subject to adjustment under specified circumstances. If events specified in the shareholder rights plan occur, each holder of rights other than the acquiring person can exercise his or her rights. When a holder exercises a right, the holder will be entitled to receive common stock valued at twice the exercise price of the right. In some cases, the holder will receive cash, property or other securities instead of common stock. We may redeem the rights for $0.01 per right at any time prior to the tenth day after a person or group becomes an acquiring person. The shareholder rights plan and the rights expire in July 2010.

Plan of Distribution

          We may sell securities:

          We will describe the terms of any offering of securities in the prospectus supplement, including:

          We may change the initial public offering price and any discount or concessions allowed or reallowed to dealers from time to time.

          If we use underwriters to sell our securities, the underwriting agreement will provide that the obligations of the underwriters are subject to certain conditions precedent and that the underwriters will be obligated to purchase all of the offered securities if any are purchased. In connection with the sale of securities, underwriters may receive compensation from us or from purchasers of securities for whom they may act as agents in the form of discounts, concessions or commissions. Underwriters may sell securities to or through dealers, and dealers may receive compensation in the form of discounts, concessions or commissions from the underwriters and/or commissions from the purchasers for whom they may act as agents.

          If we use a dealer to sell securities, we will sell the securities to the dealer as principal. The dealer may then resell the securities to the public at varying prices to be determined by the dealer at the time of resale. These dealers may be deemed underwriters, as such term is defined in the Securities Act of 1933, of the securities they offer and sell. If we elect to use a dealer to sell securities, we will provide the name of the dealer and the terms of the transaction in the prospectus supplement.

          Debt securities may also be offered and sold in connection with a remarketing upon their purchase, in accordance with a redemption or repayment by their terms or otherwise by one or more remarketing firms acting as principals for their own accounts or as our agents. We will identify any remarketing firm, the terms of any remarketing agreement and the compensation to be paid to a remarketing firm in the prospectus supplement. Remarketing firms may be deemed underwriters under the Securities Act of 1933.

          Underwriters, agents and dealers participating in the distribution of securities may be deemed to be underwriters, and any discounts and commissions received by them and any profit realized by them on resale of securities may be deemed to be underwriting discounts and commissions under the Securities Act of 1933.

          We may enter into agreements with the underwriters, agents, dealers or remarketing firms who participate in the distribution of our securities that will require us to indemnify them against specified liabilities, including liabilities under the Securities Act of 1933, or to contribute to payments that they or any person controlling them may be required to make for those liabilities. Underwriters, agents or dealers may be our customers. They may also engage in transactions with us or perform services for us or for our affiliates in the ordinary course of business.

          Each series of preferred stock and debt securities will be a new issue with no established trading market. We may elect to list any series of preferred stock or debt securities on an exchange. However, we are not obligated to do so. It is possible that one or more underwriters may make a market in a series of securities. However, they will not be obligated to do so and may discontinue market making at any time without notice. We cannot assure you that a liquid trading market for the securities (other than our common stock) will develop.

          In connection with an offering, the underwriters or agents may purchase and sell securities in the open market. These transactions may include over-allotment and stabilizing transactions and purchases to cover syndicate short positions created in connection with the offering. Stabilizing transactions consist of bids or purchases for the purpose of preventing or retarding a decline in the market price of the securities. Syndicate short positions involve the sale by the underwriters or agents of a greater number of securities than they are required to purchase from us in the offering. The underwriters also may impose a penalty bid, in which selling concessions allowed to syndicate members or other broker dealers in respect of the securities sold in the offering for their account may be reclaimed by the syndicate if the securities are repurchased by the syndicate in stabilizing or covering transactions. These activities may stabilize, maintain or otherwise affect the market price of the securities, which may be higher than the price that might otherwise prevail in the open market, and these activities, if commenced, may be discontinued at any time. These transactions may be effected on the NYSE, in the over-the-counter market or otherwise.

PART II

INFORMATION NOT REQUIRED IN PROSPECTUS

Item 14. Other Expenses of Issuance and Distribution.

          Cleco Corporation (the “Company”) estimates that expenses in connection with the offering described in this Registration Statement will be as follows:

Item 15. Indemnification of Directors and Officers.

          Section 83 of the Business Corporation Law of the State of Louisiana (the “LBCL”) provides that a corporation may indemnify any person against whom an action, suit or proceeding is brought or threatened, by reason of the fact that he is or was a director, officer, employee or agent of the corporation or was serving at the request of the corporation as a director, officer, employee or agent of another business, corporation, partnership or other enterprise, against expenses, including attorneys’ fees, judgments, fines and amounts paid in settlement actually and reasonably incurred by him in connection with any such action, suit or proceeding if he acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the corporation and, with respect to any criminal action or proceeding, had no reasonable cause to believe his conduct was unlawful. In the case of actions by or in the right of the corporation, the indemnity is limited to expenses, including attorneys’ fees and amounts paid in settlement not exceeding, in the judgment of the board of directors, the estimated expense of litigating the action to conclusion, actually and reasonably incurred in connection with a defense or settlement; provided that no indemnity may be made in respect of any matter in which the person shall have been adjudged by a court of competent jurisdiction, after exhaustion of all appeals therefrom, to be liable for willful or intentional misconduct in performance of his duty to the corporation unless and only to the extent that the court determines upon application that such person is fairly and reasonably entitled to such indemnity. To the extent a person has been successful on the merits or otherwise in defense of any action, the statute provides that he shall be indemnified against expenses actually and reasonably incurred by him in connection therewith. Section 83 also provides for, among other things, procedures for indemnification; advancement of expenses; non-exclusivity of the provisions of Section 83 with respect to indemnification and advancement of expenses; and insurance, including self-insurance, with respect to liabilities incurred by directors, officers and others.

          Article IV of the Bylaws of the Company provides that the Company shall indemnify any person who was or is, or is threatened to be made, a party to or otherwise involved in any pending or completed action, suit, arbitration, alternate dispute resolution mechanism, investigation, administrative hearing or other proceeding, whether civil, criminal, administrative or investigative (any such threatened, pending or completed proceeding being hereinafter called a “Proceeding”) by reason of the fact that he is or was a director, officer, employee or agent of the Company or is or was serving at the request of the Company as a director, officer, employee or agent of another business, foreign or nonprofit corporation, partnership, joint venture, trust, employee benefit plan or other enterprise (whether the basis of his involvement in such Proceeding is alleged action in an official capacity or in any other capacity while serving as such), to the fullest extent permitted by applicable law, from and against expenses, including attorney’s fees, judgments, fines, amounts paid or to be paid in settlement, liability and loss,

ERISA excise taxes, actually and reasonably incurred by him or on his behalf or suffered in connection with such Proceeding or any claim, issue or matter therein; provided, however, that, subject to certain exceptions set forth therein, the Company shall indemnify any such person claiming indemnity in connection with a Proceeding initiated by such person only if such Proceeding was authorized by the board of directors.

          The Bylaws further provide that (i) the Company shall from time to time pay, in advance of final disposition, all Expenses (as therein defined) incurred by or on behalf of any person claiming indemnity thereunder in respect of any Proceeding, (ii) the right to indemnification provided therein is a contract right and no amendment, alteration or repeal of the Bylaws shall restrict the indemnification rights granted by the Bylaws as to any person claiming indemnification with respect to acts, events and circumstances that occurred, in whole or in part, before such amendment, alteration or repeal, (iii) any such indemnification may continue as to any person who has ceased to be a director, officer, employee or agent and may inure to the benefit of the heirs, executors and legal representative of such person and (iv) the right of indemnification and to receive advancement of expenses contemplated by Section 1 of Article IV of the Bylaws are not exclusive of any other rights to which any person may at any time be otherwise entitled, provided that such other indemnification may not apply to a person’s willful or intentional misconduct. The Bylaws also set forth certain procedural and evidentiary standards applicable to the enforcement of a claim thereunder.

          The Bylaws also provide that the Company (i) may procure or maintain insurance or other similar arrangement, at its expense, to protect itself and any director, officer, employee or agent of the Company or other corporation, partnership, joint venture, trust or other enterprise against any expense, liability or loss asserted against or incurred by such person, whether or not the Company would have the power to indemnify such person against such expense or liability and (ii) shall indemnify officers and directors of the Company to the extent they are not covered by the insurance, whether or not such persons would otherwise be entitled to indemnification under the Bylaws, as provided in policies covering liabilities up to $85 million incurred by directors and officers in their capacities as such, and has fiduciary and employee benefit liability insurance policies covering liabilities up to $65 million incurred by directors, officers and certain other employees of the Company in connection with the administration of the Company’s employee benefit plans.

          Section 24(C)(4) of the LBCL provides that a corporation may eliminate or limit the liability of a director or officer to the corporation or its shareholders for monetary damages for breach of fiduciary duty, except for liability (i) for any breach of the director’s or officer’s duty of loyalty to the corporation or its shareholders, (ii) for acts or omissions not in good faith or that involve intentional misconduct or a knowing violation of law, (iii) under Section 92(D) of the LBCL relating to unlawful dividends and other unlawful distributions, payments or returns of assets and (iv) for any transaction from which the director or officer derived an improper personal benefit. The Company’s Articles of Incorporation include a provision consistent with Section 24(C)(4) of the LBCL. Such provision further provides that (a) if the LBCL is subsequently amended to authorize action further eliminating or limiting a director’s or officer’s liability, such liability will be eliminated or limited to the fullest extent permitted by such law, as so amended, and (b) if such provision limiting or eliminating liability is repealed or modified, the right or protection of a director or officer of the Company existing at the time of such repeal or modification will not be affected thereby.

Item 16. Exhibits.

          See Index to Exhibits beginning on page II-6.

Item 17. Undertakings.

          (a)     The undersigned registrant hereby undertakes:

          (b)     The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant’s annual report pursuant to section 13(a) or section 15(d) of the Securities Exchange Act of 1934 that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

          (c)     Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.

          (d)     The undersigned registrant hereby undertakes to file an application for the purpose of determining the eligibility of the trustee to act under subsection (a) of section 310 of the Trust Indenture Act of 1939 (the “Act”) in accordance with the rules and regulations prescribed by the Commission under section 305(b)(2) of the Act.

SIGNATURES

          Pursuant to the requirements of the Securities Act of 1933, the Registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-3 and has duly caused this Registration Statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of Pineville, the State of Louisiana, on June 9, 2005.

          Pursuant to the requirements of the Securities Act of 1933, this Registration Statement has been signed by the following persons in the capacities and on the dates indicated.
