TransAlta adds 123MW of wind power ahead of schedule

Dec 6, 2010

Calgary, Alberta, December 6, 2010 – TransAlta Corporation (TSX:TA) (NYSE:TAC) today announced the company has commissioned 123 megawatts (MW) from two new wind facilities – one in Alberta, the other in New Brunswick – both ahead of schedule and on budget.

“TransAlta is committed to growing and diversifying our generation fleet.  With the successful completion of these two facilities our wind portfolio is now 1,073 MW, which is the largest in Canada,” said Steve Snyder, President and CEO. “We continue to deliver our wind projects on time and on budget despite challenges like extreme weather.”

The $135-million Ardenville Wind Facility, located about eight kilometres south of Fort Macleod, Alberta, involved the installation of 23 Vestas V90-3.0 MW wind turbines.  The facility has an installed capacity of 69 MW and is expected to generate enough power for about 11,500 average homes.

The $102-million expansion to the Kent Hills Wind Facility, located about 33 kilometres southwest of Moncton, New Brunswick, has increased the existing generation capacity by 54 MW with the installation of 18 Vestas V90-3.0 MW wind turbines.  The expansion will generate enough electricity to meet the needs of about 9,000 homes.

With facilities from Alberta to New Brunswick, TransAlta is Canada’s largest producer of wind power, operating more than a third of Canada’s installed 3,549 MW wind capacity.  Over the last two years TransAlta has successfully constructed three new wind facilities and completed expansions of two existing facilities.

TransAlta’s renewable generation portfolio now totals 2,155 MW; including 1,073 MW of wind, 893 MW of hydroelectric, 25 MW of biomass and 164 MW of geothermal energy in California through a partnership with CE Generation LLC.
