Construction has got underway for Renewables developer Fotowatio Renewable Ventures’s (FRV) second battery storage project in the UK, together with partner Harmony Energy. FRV, owned by Saudi Arabian industry group Abdul Latif Jameel, has deployed hundreds of megawatts of wind and solar projects around the world since 2006, when it built what was then the world’s largest solar plant, a 23MWdc project in Spain. However, the company only began its involvement in battery storage in 2019 with the announcement of its first grid-scale battery project, the 7.5MW / 15MWh Holes Bay project in England.
