Summerview 1

The Summerview 1 wind facility is located adjacent to the Summerview 2 wind facility, in the northeast portion of the municipal district of Pincher Creek, Alberta, north of the Oldman River and adjacent to the west boundary of the Peigan Reserve.

The facility began with the commissioning of one of the largest wind turbines in Western Canada at that time. It produced 1.8 megawatts of power and was commissioned in January 2002.

Phase I of this project was completed in 2004. The facility currently includes 38 Vestas V80 wind turbines with 65-metre towers for a total of 68 megawatts of installed capacity. It produces more than 209,000 megawatt-hours annually.

The second phase came online in 2010 and brought the wind facility to a total of 136.2 megawatts built over 6,000 acres.

Environmental highlights
