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.
