Ouessant Island

The two EMS projects on Sein island and Ouessant island are EDF Store & Forecast’s first achievements in microgrid supply/demand balance management. 

  • Context: a 100% renewable production target for this non interconnected island
  • Goal: to limit the use of genset
    to compensate intermittency of PV production
    …while ensuring quality and safety of the power system
  • Project: genset (4.3 MW) + PV (45 kWp) + Marine gen. (->250 kW) + Li-ion Battery (1 MW–0,56 MWh)
  • Status: commissioned in September 2017
