The first phase of this project was completed in 2004. The second phase came online in 2010 and brought the wind facility to a total of 136.2 megawatts built over 6,000 acres.
The Summerview wind facility (phase one) currently includes 39 wind turbines for a total of 70.2 megawatts of installed capacity, and produces more than 209,000 megawatt hours annually – enough energy to reduce carbon dioxide emissions by 146,250 tonnes per year.
The second phase of the wind facility added 22 three-megawatt turbines atop 80 metre towers for an additional 66 megawatts.
The facility is located in the northeast portion of the municipal district of Pincher Creek, just north of the Oldman River and adjacent to the west boundary of the Peigan Reserve, in Alberta.
