Despite a sharp share price fall of late, investor interest in Battery Energy Storage Systems (BESS) technology continues to grow, as it addresses many of the intermittency problems caused by rising renewable energy generation. The UK’s two leading BESS players, which supply power grid-related technical services, are Gresham House Energy Storage (GRID) and Gore Street Energy Storage (GSF); they are capitalised at £869m and £500m, respectively. Other Renewable Energy Infrastructure Funds (REIF), 22 of which are now quoted, are moving into the BESS space. Most recently, the turmoil in the UK gas market provides further opportunities for funds with BESS operations.
