Water energy

The Entracque Power Plant, also known as The Upper Gesso Plant, is a pumped-storage hydroelectric power station located in Valle Gesso just south of Entracque, Italy. The power station contains pump-generators for two co-located but hydraulically separated power schemes; the Chiotas-Piastra Plant and Rovina-Piastra Plant. The Chiotas' upper reservoir, Lago del Chiotas, is located much higher in the valley and larger than Rovina's Lago della Rovina which affords it the ability to produce more electricity. The installed capacity of Chiotas is 1,184 megawatts (1,588,000 hp) with a hydraulic head (water drop in elevation) of 1,048 m (3,438 ft) while Rovina has an installed capacity of 133.67 megawatts (179,250 hp) and a head of 598 metres (1,962 ft).
