The Aberfeldie Dam is a dam on the Bull River in the southeast of the Canadian province of British Columbia . The Scottish region of Aberfeldy gave its name to the dam . The power plant and dam are operated by BC Hydro .
dam
Aberfeldie Dam is located 30 km east of the city of Cranbrook , 11.5 km above the confluence of the Bull River and the Kootenay River . A first dam was built in 1920–1922 by British Columbia and Alberta Power Company Ltd. built. The current dam was completed in 1953 and replaced the old dam. He is a 27 m high and 134 m wide gravity dam made of concrete .
Reservoir
The reservoir has a length of 600 m and a width of about 100 m. The catchment area covers 1530 km². The mean discharge at the dam is around 31.85 m³ / s.
power plant
The first power plant was in operation between 1923 and October 2006. It had two turbines with 2.5 MW each. The new power plant ( ⊙ ) went into operation at the beginning of 2009 . The power station house houses three horizontal-axis Francis turbines of 8.3 MW each. The total expansion flow of the three units is 38.5 m³ / s. The average annual energy production is 105 GWh. Previously it was 35 GWh. The cost of construction was 95 million Canadian dollars .
The water enters a 850 m long underground pipeline with a diameter of 3.35 m via two inlets with a capacity of 20 m³ / s each. This is followed by a 150 m long overhead pipe with a diameter of 2.9 m. A water lock (15 m high and 13 m diameter) is located at the transition to the high pressure line. This has a length of 150 m and a diameter of 2.74 m and leads the water directly to the power plant. The net height of fall is 84 m.
