The Black Lake became a source of electricity production with the construction in 1933 of an 80 megawatts power station. The plant has been shut down since 2002. EDF (Electricity of France) proposed to build a new power station with a capacity of 55 megawatts. It would be capable of delivering its power to the network in a few minutes in the event of very high consumption. Being smaller and mainly underground, the new plant would also fit better into the landscape according to the firm. EDF also proposes an environmental component, alongside the energy part, related to the European natural site classified Natura 2000 located near the facility.
