TRANSCANADA: TransCanada Begins Construction of $500 Million Facility in Coolidge

COOLIDGE, ARIZONA--(Marketwire - Aug. 10, 2009) - TransCanada (TSX:TRP) (NYSE:TRP) has begun construction of a nominal 575 megawatt power facility that will provide an economic boost to the rural community of Coolidge. Hundreds of jobs will be created during the construction phase of the project and approximately 12 permanent full time jobs will be available when completed.

The power facility is expected to be online by May 2011. The simple-cycle natural gas-fired peaking facility, with the capacity to power 575,000 homes, will provide a quick response to peak power demand. The facility will also provide reserve capacity and the ability to generate power quickly to support power reliability in the region. Arizona-based utility SRP has signed a 20-year power purchase agreement to secure 100 per cent of the output from TransCanada's Coolidge Generating Station.
