Located deep in the Hérens valley (alt. 1896 m), the Ferpècle pumpingstation collects the water from the Ferpècle and Mont Miné glaciers.Every year, 3 pumps transfer around 60 million m3 of water up the 212-metre gulley to the Arolla pumping station via the Maya reservoir.The total output from the facility is 8.4 m3 / second.
The power station is hidden inside the mountain. Only a dam, two sandtraps and a gravel trap are visible. To prevent floodwater entering the installations, the Ferpècle water intake is equipped with an access limiter to the sand trap.
