The Menihek Lakes form a flow-regulated body of water in the central east of the Labrador Peninsula in the Canadian province of Newfoundland and Labrador . The reservoir and hydroelectric power station were built between 1951 and 1954. The plant was operated by the Iron Ore Company of Canada (IOC) until 2007 . Since then, the plant has been operated by Nalcor Energy .
Barrier structure and reservoir
The Menihek Lakes are traversed by the Ashuanipi River . At the site of the Menihek Rapids , a 228.6 m long concrete barrier was erected. The mean discharge at this point is 395 m³ / s. The upstream catchment area has an area of 19,166 km². The main tributaries of the Menihek Lakes are the Ashuanipi River and the McPhadyen River . The reservoir covers an area of 277 km². It measures 112 km in north-south direction. The maximum width is 6.7 km. The target is 485 m . The usable storage volume is 423.8 million cubic meters. The flood relief is designed for a discharge of 4248 m³ / s. Downstream is the Smallwood Reservoir, built between 1967 and 1971 .
power plant
The power station building ( ⊙ ) is designed for four turbine sets. In 1954, two turbines, each with an output of 4.4 MW and a head of 10.4 m, went into operation. In 1960 a third turbine was added with an output of 9.9 MW and a head of 12.2 m. The power plant thus has a total installed capacity of 18.7 MW. The annual energy production in 2013 was 45 GWh. Nalcor signed a 40-year contract with Hydro-Québec , which regulates the purchase of the electricity produced for their customers in the Schefferville region.
