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.

Details of a new cap-and-floor scheme to support long-duration energy storage (LDES) in the United Kingdom have been revealed, including significant decisions on eligibility criteria.
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.
