CALGARY, Alberta (Sept. 26, 2002) ­ TransAlta Corporation (TSX: TA; NYSE: TAC) is removing from service the 154-megawatt Pierce Power Station located in Frederickson, Washington, as intended when commissioned in August 2001. TransAlta built the simple-cycle gas-fired power facility to help alleviate a short-term power shortage in the Pacific Northwest.
