After the Z’Mutt pumping station, Arolla is the most powerful station at the Grande Dixence site. It receives the water already pumped via Ferpècle, supplementing it with water from the Tsidjiore Nouve and Bertol glaciers. The Arolla facility collects and discharges around 90 million m3 of water every year. Three 16.2 MW dual-inlet pumps each transfer 4.2 m3 of water per second a height of 312 metres.
