Project Description:

The proponent proposes to construct and operate two hydroelectric power generating facilities on the lower section of the Churchill River at Gull Island and Muskrat Falls in Labrador . Gull Island is located approximately 100 kilometres and Muskrat Falls 30 kilometres to the southwest of the Town of Happy Valley-Goose Bay , respectively. The two facilities will have a combined power generation capacity of approximately 2,800 megawatts (MW). The Gull Island facility will have a capacity of 2,000 MW, including a dam 99 metres high by 1,315 metres long with a reservoir 225 kilometres long, flooding an additional 85 square kilometre area. The Muskrat Falls facility will have a capacity of 800 MW, including a dam at the north section 32 metres high by 180 metres long, and, south section 29 metres high by 370 metres long with a reservoir 60 kilometres long, flooding an additional 36 square kilometre area. The project will also include interconnecting transmission lines to the existing Labrador grid at Churchill Falls Generating Station. Construction is scheduled to begin in mid-2009 at Gull Island with first power generation in mid-2014, and construction of Muskrat Falls is proposed to start three years following the start of construction at Gull Island.
