Government launches scheme to attract renewable energy storage investment

The government has launched a new scheme to help build energy storage infrastructure.

It is hoped this will result in the first significant long duration energy storage (LDES) facilities in nearly four decades, and in turn, create back up renewable power and bolster the UK’s energy security.

The technology is like giant batteries and work by storing renewable energy and releasing it onto the grid and into homes when needed. This includes pumped storage hydro, which stores electricity by pumping water up a reservoir, to be released later.

There are high up-front costs, which have previously held back investment in this. The operating costs, however, are low.

Energy Minister, Michael Shanks, said: "We are wasting no time in unlocking Britain’s vast renewable potential by expanding wind and solar power. But we also need to increase our ability to store this energy for when the sun isn’t shining, or the wind isn’t blowing.

"We’re reversing a legacy that has seen no new long duration storage built for 40 years - and taking steps to unleash private investment in both established and new technologies.  

"With these projects storing the surplus clean, homegrown energy produced from renewable sources, we can boost our energy security by relying less on fossil fuels, protect household bills, and help deliver our key mission to make Britain a clean energy superpower."

Beatrice Filkin, director of major projects at Ofgem said: "We are pleased to see the government’s publication today on its plans for long duration electricity storage. Unlocking investment in this important technology is another significant step towards decarbonisation of the  the power system.  

"We are looking forward to continuing to work closely with government as we take on the role of regulator and investment support scheme delivery body for the sector."
