Sitting in the French Alps, Grand'Maison is Europe’s largest pumped storage plant at 1,800 MW capacity. The plant has multiple production units including 4 Pelton turbines and 8 reversible pumps, which first went into service in 1986. During the XFLEX HYDRO project, hydraulic short circuit will be demonstrated using new turbine runners and automation techniques for advanced control and efficiency.
During the project, the flexibility technologies will be trialled at 7 demonstration sites. These are located at existing European hydropower stations. Each XFLEX HYDRO demonstration site will test a different technological configuration, installed together with the Smart Power Plant Supervisor in every case.
