GREAT BRITAIN — Ofgem, Great Britain's energy regulator, has provisionally approved 16 long-duration electricity storage projects. These projects are defined as facilities capable of storing and releasing electricity for eight hours or longer.

The approved projects are located across England, Scotland, and Wales, and aim to balance the supply and demand of electricity. Three of the 16 projects are pumped storage hydroelectric power stations in Northern Scotland, marking the first new facilities of their kind in Great Britain since 1984. The Dinorwig hydropower plant in north Wales was constructed in 1984.

One of the Scottish pumped storage projects, Statera Energy’s Loch Kemp project, will draw water from Loch Ness. SSE’s Coire Glas project is situated at Loch Lochy, between Fort William and Inverness. Gilkes Energy’s Earba project is expected to be the largest pumped storage hydro facility in the UK.

Energy Minister Michael Shanks stated these projects demonstrate the government's commitment to building new infrastructure, forty years after the country’s previous pumped storage facility. Akshay Kaul, the director general for infrastructure at Ofgem, noted the variety of technologies proposed.

Thirteen of the 16 projects utilize energy storage technologies other than pumped storage hydro. These include compressed air, lithium-ion batteries, and vanadium redox flow batteries. Kaul stated that Ofgem is establishing the necessary infrastructure for renewable energy to flourish, enhancing energy security, and reducing dependence on global gas markets. He added that this development brings Great Britain closer to achieving the long-duration energy storage required in a clean power system to maintain a secure supply.

Why It Matters

The provisional approval of 16 long-duration electricity storage projects addresses Great Britain's energy security and supports renewable power integration. The projects, which include the first new pumped storage hydroelectric facilities since 1984, are designed to stabilize electricity grids by ensuring consistent power supply when renewable sources like solar or wind are not generating at full capacity.

These initiatives aim to reduce reliance on volatile fossil fuel markets and integrate a diverse range of energy storage technologies, from traditional pumped hydro to advanced battery systems. This development could reshape the national energy infrastructure and contribute to a more resilient and sustainable power system across England, Scotland, and Wales.
