UK regulator reveals criteria for long-duration storage

UK regulator reveals criteria for long-duration storage Long duration energy storage (LDES) support scheme will have eight-hour minimum. First application round opens to well-established technologies, such as lithium-ion battery technology, with at least 100 MW capacity in April 2025. Flow batteries, compressed air, and liquid air likely to progress in second round, says regulator.

Ofgem has confirmed that the cap-and-floor scheme will be open to LDES assets that can provide power for eight hours or more, up from a six-hour duration put forward in earlier proposals. The energy sector regulator has also committed to a 100 MW minimum capacity for its “stream 1” application round, followed by a 50 MW minimum for “stream 2”. The stream 1 round will be open to well-established storage technologies that meet Ofgem’s technology readiness nine (TRL9) criteria. The second will be open to TRL 8 technologies.
