<br wp="br1">
<p>CALGARY, Alberta (May 31, 2002) &#173; 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.

<p>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".

<p>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.

<p>"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."

<p>The filing is on TransAlta's website at www.transalta.com<font color="#00aa00">

 under "Investor Information".

<p><em>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.</em>
