Djúpadalsvirkjun small hydropower plant
The Djúpadalsvirkjun small hydropower plant is located in Eyjafjörður in North Iceland.
The project includes a 1.8 MW hydroelectric power plant in the Djúpadalsá river in NE Iceland. The project is a run-of-a-river scheme. The dam/spillway is a 5 m high concrete structure, with bottom outlet, associated gate and control mechanism and the intake canal, excavated in rock, is 280 m long and up to 10 m deep. Penstock is 900 m long, made of fiber reinforced plastic pipes, 1400 mm in diameter. The powerhouse will have two turbines, each capable of producing 0.9 MW.
