Located in the Eastern Pyrenees, the eLLO solar plant main features are :

  • 9 MWe power output with a thermal energy storage capacity, i.e. the electricity consumption of more than 6,000 households
  • Built on a 36-hectare site
  • 95,200 mirrors fitted to 23,800 collector panels covering a total surface area of 153,000 m2
  • 9 energy accumulators, providing 4 hours of full-charge storage capacity.

The project was developed by SUNCNIM which specially secured :

  • Municipal Land
  • Power Purchase Agreement (PPA) signed with EDF in the framework of a french state call of tender awarded in 2012
  • All necessary permits
  • Financing
  • Grid connection
