Construction will commence in the second quarter of 2009 with commercial operations expected to begin in the first quarter of 2010. Once the second phase is completed, the Summerview site will have a total installed capacity of 136MW and will provide on average a total of 395,000MWh per year.

The Summerview expansion will be located adjacent to the original site and will include twenty-two 3MW, V90 Vestas wind turbines. Delivery of the turbines and construction are scheduled to begin in the third quarter of 2009.

TransAlta will serve as its own general contractor and will continue to work with local firms during construction. The project is subject to provincial regulatory and environmental approvals as well as municipal land use permitting.

Steve Snyder, TransAlta’s president and CEO, said: We have identified the potential to develop an additional 500MW of wind generation in southern Alberta over the next five years. Our ability to execute on these future opportunities is largely dependent on the addition of new transmission capacity within the province.
