Wedoany.com Report-Sept. 24, Ofgem, the UK’s energy regulator, announced that 77 long duration electricity storage projects have progressed to the final assessment stage of its cap-and-floor support scheme, launched in April. The initiative aims to drive significant investment in technologies that store excess renewable energy and release it during peak demand, reducing reliance on gas plants and minimizing wind power curtailment.

The selected projects encompass a variety of storage technologies, including lithium-ion batteries, flow batteries, and pumped hydro. Ofgem emphasized that this diverse mix supports the development of a secure, efficient, and adaptable energy system. The projects are expected to enhance the UK’s ability to utilize renewable energy effectively, contributing to a more sustainable energy landscape.

Beatrice Filkin, director of major projects infrastructure at Ofgem, stated: “Renewable power is the key to seizing control of our own energy system and end the costly reliance on the turbulent wholesale gas market, so we don’t want to see a single watt go to waste. Through Ofgem’s cap and floor process we are beginning to identify the projects that we think are best placed to capture and make the most of our precious natural resources.”

Energy Minister Michael Shanks added: “This is another huge step forward in reversing the legacy that has seen no new long duration storage built for 40 years – a technology that will see Britain take back control of its energy supply and protect billpayers for good.”

From an initial pool of 171 applications, the 77 projects now advancing will undergo detailed evaluations, with successful projects to be announced in summer 2026. The cap-and-floor scheme is designed to provide financial stability, encouraging investment in innovative storage solutions that support the integration of renewable energy into the grid.

By fostering the development of long duration energy storage, Ofgem aims to enhance energy security and efficiency, ensuring that surplus renewable power is effectively utilized. The initiative reflects a commitment to building a resilient energy infrastructure that meets growing demand while advancing sustainability goals across the UK.
