Item 1.  Description of the Proposed Transaction

A.   Introduction

     By order dated June 14, 2002, the Securities and Exchange Commission (the
"Commission") authorized the acquisition of Powergen Ltd. (formerly Powergen
plc, "Powergen") by E.ON AG ("E.ON") and certain related transactions. E.ON AG,
et al., Holding Co. Act Release No. 27539 (June 14, 2002) ("2002 Order"). The
2002 Order granted the Form U-1 Application-Declaration, originally filed in
File No. 70-9961 on September 4, 2001, and subsequently amended by Amendment No.
1 filed on October 23, 2001, Amendment No. 2 filed on December 21, 2001,
Amendment No. 3 filed on June 11, 2002, and Amendment No. 4 filed on June 14,
2002. On February 21, 2003, the Commission approved the transfer of Powergen US
Investment Corp. from the Powergen chain of companies to E.ON US Holding GmbH
(the "Transfer") in Holding Co. Act Release No. 27654 (Feb. 21, 2003) ("Transfer
Order").

B.   General Request

     Applicants submit this Post-Effective Amendment No. 1 ("Amendment") to
request that the Commission release its reservation of jurisdiction and
unconditionally approve the deregistration of Powergen US Holdings Limited,
Powergen US Investments, Powergen Luxembourg Holdings sarl and Powergen
Luxembourg sarl (the "Powergen Intermediate Holding Companies") and issue an
order to such effect pursuant to Section 5(d) of the Public Utility Holding
Company Act of 1935, as amended (the "1935 Act").

C.   Discussion

     Under the 2002 Order, the SEC authorized E.ON to acquire all of the issued
and outstanding common stock of Powergen and, through the acquisition of
Powergen, LG&E Energy Corporation ("LG&E Energy") and its public utility
subsidiaries, Louisville Gas and Electric Company ("LG&E") and Kentucky
Utilities Company ("KU") (the "Acquisition"). On July 1, 2002, E.ON consummated
the Acquisition and registered as a holding company under Section 5 of the 1935
Act.1

     Under the 2002 Order, E.ON also was authorized to complete a reorganization
(following the Acquisition) whereby the ownership of E.ON US Investments Corps.
(formerly, Powergen US Investments Corps., "EUSIC"), an intermediate holding
company of Powergen and the immediate parent company of LG&E Energy, would be
transferred to E.ON U.S. Verwaltungs GmbH ("E.ON US"), a direct subsidiary of
E.ON, in exchange for cash or a note. Following the reorganization, E.ON would
hold all of the outstanding voting stock of LG&E Energy through


----------------------------
1 By order dated December 6, 2000, the Commission authorized Powergen to acquire
LG&E Energy. See --- Powergen plc, Holding Co. Act Release No. 27291 (Dec. 6,
2000). Subsequent to the issuance of this order, Powergen and the Powergen
Intermediate Holding Companies registered under the 1935 Act. Following the
Acquisition, Powergen and the Powergen Intermediate Holding Companies remained
registered pursuant to Section 5 of the 1935 Act and LG&E Energy continued to
claim exemption from registration under Section 3(a)(1).




E.ON US and EUSIC, and E.ON US would register as a holding company. EUSIC would
remain a registered holding company under the Act by virtue of its indirect
ownership interest in LG&E and KU, both public utility companies. Consequently,
the Powergen Intermediate Holding Companies would cease to hold voting interests
in LG&E Energy directly or indirectly and thereby cease to be holding companies
of any public utility company. The Commission reserved jurisdiction over the
proposed deregistration of the Powergen Intermediate Holding Companies until the
completion of the reorganization.

     Since the Acquisition, ownership of EUSIC has been transferred from
Powergen Luxembourg Holdings sarl (10%) and Powergen Luxembourg Investments sarl
(90%) to Powergen Luxembourg sarl. In addition, Powergen Luxembourg Investments
sarl has been liquidated. On March 1, 2003, Powergen Luxembourg sarl transferred
99.5% of its shareholding in EUSIC to E.ON US for cash as proposed in the
Original Financing Application and approved in the Transfer Order. It retained
one (1) voting share that constitutes 0.5% of the ownership in EUSIC in order to
preserve certain tax efficiencies under the laws of Luxembourg.

     Presently, E.ON indirectly owns LG&E Energy through E.ON US and EUSIC. The
Powergen Intermediate Holding Companies do not own any voting interest in any
U.S. public utility company except for the sole voting share held by Powergen
Luxembourg sarl in EUSIC. E.ON's indirect ownership of less than 1% of the
voting interest in EUSIC and, consequently, in LG&E Energy, is immaterial and
does not affect the U.S. utility operations of LG&E Energy.


Item 2. Fees, Commission and Expenses

     Applicants expect to pay or incur, directly or indirectly, approximately
$25,000 in connection with the request herein.

Item 3. Applicable Statutory Provisions

     Applicants request that the Commission issue an order declaring the
deregistration of the Powergen Intermediate Holding Companies pursuant to
Section 5(d) of the 1935 Act in light of the fact that the Powergen Intermediate
Holding Companies are no longer holding companies within the meaning of Section
2(a)(7) of the 1935 Act. Section 5(d) provides that

          Whenever the Commission, upon application, finds that a registered
          holding company has ceased to be a holding company, it shall so
          declare by order and upon the taking effect of such order the
          registration of such company shall, upon such terms and conditions as
          the Commission finds and in such order prescribes as necessary for the
          protection of investors, cease to be in effect.

     Section 2(a)(7) of the 1935 Act defines a "holding company" as

          (A) any company which directly or indirectly owns, controls, or holds
          with power to vote, 10 per centum or more of the outstanding voting
          securities of a public-utility company or of a company which is a
          holding company by virtue of this clause or




          clause (B), unless the Commission, as hereinafter provided, by order
          declares such company not to be a holding company; and

          (B) any person which the Commission determines, after notice and
          opportunity for hearing, directly or indirectly to exercise (either
          alone or pursuant to an arrangement or understanding with one or more
          persons) such a controlling influence over the management or policies
          of any public-utility or holding company as to make it necessary or
          appropriate in the public interest or for the protection of investors
          or consumers that such person be subject to the obligations, duties,
          and liabilities imposed in this title upon holding companies.

     Upon completion of the Transfer, the Powergen Intermediate Holding
Companies ceased ownership, direct or indirect, of any significant or material
interests in EUSIC and LG&E Energy and its public utility subsidiaries. The
Powergen Intermediate Holding Companies were formed to effect Powergen's
acquisition of LG&E Energy on a tax efficient basis and continue to serve as
financing conduits, enabling E.ON and Powergen to preserve certain efficient
financing arrangements since the Acquisition. These intermediary companies,
including Powergen Luxembourg sarl which holds a residual 0.5% in EUSIC, (i)
cannot exert any influence over the management or policies of E.ON US, which
directly holds the ownership interests of LG&E Energy and its public utility
subsidiaries, and (ii) do not have authorization to issue securities externally.
Powergen Luxembourg sarl's indirect minority interest (through EUSIC) in a U.S.
public utility company does not warrant a finding that Powergen Luxembourg sarl
is a holding company within the meaning of Section 2(a)(7) of the 1935 Act.

     Consequently, none of the Powergen Intermediate Holding Companies (i)
directly or indirectly own, control or hold with the power to vote 10% or more
of the outstanding voting securities of any public utility company or any
company that is a holding company by virtue of clause (A) or (B) of Section
2(a)(7) of the 1935 Act, or (ii) exercise any controlling influence over the
management or policies of any public utility or holding company.

Item 4. Regulatory Approvals

     No federal or state regulatory approval, other than the authorization of
the Commission, is required in connection with the deregistration of the
Powergen Intermediate Holding Companies.

Item 5. Procedure

     Applicants respectfully request that the Commission release its reservation
of jurisdiction and forthwith issue an order granting and permitting this
Amendment to become effective.

Item 6. Exhibits and Financial Statements

     Not applicable.




Item 7. Information as to Environmental Effects

     The deregistration of the Powergen Intermediate Holding Companies as
proposed herein neither involves a "major federal action" nor "significantly
affects the quality of the human environment" as those terms are used in Section
102(2)(C) of the National Environmental Policy Act. No federal agency is
preparing an environmental impact statement in connection with Applicants'
request herein.

     Pursuant to the Public Utility Holding Company Act of 1935, Applicants have
duly caused this Application-Declaration to be signed on their behalf by the
undersigned thereunto duly authorized.
