Dubai Electricity and Water Authority (DEWA) has signed a cooperation agreement with the renewables arm of major French utility EDF to share expertise and experience in areas including energy storage, renewables, EV chargers and energy system integration.

Around 90 companies, including EDF, Enel and Engie, have expressed interest in financing and implementing research and development (R&D) projects relating to energy storage integration in Brazil, according the country’s energy regulator ANEEL.

Reports that a grid operator in France has found battery-based energy storage “too costly” to be used to integrate renewable energy have been criticised by a spokesman for energy storage developer Younicos.
