TransAlta responds to FERC's May 21, 2002 data request

CALGARY, Alberta (May 31, 2002) ­ TransAlta Corporation (TSX: TA; NYSE: TAC) today responded to the second in a series of U.S. Federal Energy Regulatory Commission (FERC) data requests. This request, issued on May 21, 2002, related to "round trip" trades.

FERC requested that all sellers of wholesale electricity and/or ancillary services in the U.S. portion of the Western Systems Coordinating Council (WSCC) to admit or deny whether during 2000 and 2001 they conducted trading that "involves the sale of an electricity product to another company together with a simultaneous purchase of the same product at the same price".

After a thorough review, TransAlta confirmed it did not participate in the types of trades outlined in this FERC request. The company concluded it operated in accordance with all applicable laws, rules, regulations and tariffs.

"TransAlta does not participate in and has nothing to gain by doing these types of trades," said Steve Snyder, TransAlta President and CEO. "Furthermore, traders would not benefit because we do not incent our traders on volumes."

The filing is on TransAlta's website at under "Investor Information".

TransAlta Corporation is Canada's largest non-regulated electric generation and marketing company, with more than $7 billion in assets and 9,000 megawatts of capacity either in operation or under construction. As one of North America's lowest-cost operators, our growth is focused on developing coal- and gas-fired generation in Canada, the U.S. and Mexico.
