First proposed in 2007, the turbines started operation in early 2011. The investment in the plant was C$355 million by the San Francisco-based Pattern Energy Group, with a part loan from Manitoba Hydro. The project had been initially planned at 300 MW capacity but was downsized due to economic conditions in 2008.
