UK minister outlines support for long-duration electricity storage

The UK Minister for Energy, Michael Shanks, has issued an open letter explaining how the government is supporting the roll-out of long duration electricity storage (LDES) via Ofgem’s cap and floor scheme.

• The letter states that Ofgem’s cap and floor regulatory framework will be used to support delivery of the next generation of LDES projects, providing revenue certainty by setting minimum and maximum income levels for qualifying storage assets.
• It positions this approach as part of the UK government’s broader energy policy and system planning, with Ofgem implementing the scheme to enable investment in long-duration storage, though specific timelines, project sizes, or funding volumes are not detailed in the provided text.
