CALGARY, Alberta (May 22, 2002) ­ TransAlta Corporation (TSX: TA; NYSE: TAC) today responded to the U.S. Federal Energy Regulatory Commission (FERC) May 8, 2002 data request. It requested that 150 sellers of wholesale electricity and/or ancillary services to the California electricity market respond to questions around their trading strategies in California during 2000 and 2001.

In response to FERC's request, TransAlta officials reviewed over 45,000 transactions conducted in 2000 and 2001. The company concluded it operated in accordance with all applicable laws, rules, regulations and tariffs.

"TransAlta is dedicated to the highest standards of ethical business conduct," said Steve Snyder, TransAlta President and CEO. "Our participation in the California market has complied with TransAlta's strict internal trading guidelines and in keeping with our practice of energy trading supporting our assets."
