France’s grid operator will test storing excess wind and solar power in batteries to reduce the need to build new transmission lines that involve heavy construction work and take longer to complete.
Network operators across Europe are seeking ways to both minimise the cost and environmental impact of the energy transition. Reseau de Transport d’Electricite estimates that France will need to spend $37 billion by 2035 to renovate the network, build new interconnectors and make the grid more flexible to accommodate an influx of wind and solar farms as the country reduces its reliance on nuclear power.
“There’s no strong appetite from the society for planting more pylons and for building more electric transformers,†Francois Brottes, chairman of RTE, said at a presentation of the pilot project. The project consists of installing three batteries near wind farms, far enough apart so they can each store enough power to supply a city of 10,000 inhabitants for a few hours, said Oliver Grabette, RTE’s head of solutions.
