Providing bespoke support for long duration electricity storage (LDES) could distort the market, Energy UK has warned. The industry trade body was responding to the government’s latest consultation on developing a cap and floor scheme that aims to overcome barriers to LDES, such as a lack of revenue certainty, high upfront capital costs and long build times. While it describes support to get LDES off the ground as “essential”, some of the trade body’s members have concerns that the support could impact unsupported projects in shorter-duration markets.
