The Isles of Scilly are to be used as a test hub for smart energy technology in a £10.8 million project backed by the EU and Hitachi. The project will see rooftop solar panels and new energy management systems installed on 100 council-owned homes, about a tenth of the islands’ housing stock, with the households receiving discounted electricity. Ten of the homes will also be fitted with batteries or other technologies to help manage lags between supply and demand. A subsequent phase of the Smart Energy Islands project is expected to see electric cars deployed on the archipelago, with their batteries also used to help manage supply and demand. By 2025, the project aims to cut electricity bills by 40 per cent, meet 40 per cent of energy demand from renewables and for 40 per cent of vehicles on the islands to be either electric or low carbon.
