Hydroelectric plant of Vilaller Monument · Vilaller, Alta Ribagorça, Lleida Image of Vilaller, not of the place itself. The Vilaller hydroelectric power station, in the basin of the Noguera Ribagorçana and part of ENHER's system of hydroelectric plants in the Alta Ribagorça, was built in 1952. It draws water through a 6.3-kilometre channel with a flow of 7 cubic metres per second and generates 4,200 kilowatts of power. It was part of the network of hydroelectric works built in the area between 1940 and 1960, which also included the plants of Senet, Bono and Pont de Suert, harnessing the valley's differences in elevation to produce electricity.
