New study shows almost 7GW of battery storage in U.K. pipeline


The UK’s nascent energy storage sector is surpassing all expectations and is set to deliver close to 7GW of capacity in the next few years, over a decade earlier than previously thought. That is the conclusion of a new analysis by trade bodies RenewableUK and the Solar Trade Association (STA) published ahead of the groups’ first energy storage conference in London today.

It shows that planning applications for new battery storage projects have soared from just 2MW of capacity in 2012 to a cumulative total of 6,874MW today. Crucially, the bulk of the pipeline of proposed projects has a good likelihood of being built. Currently 92 per cent of storage projects secure planning permission from their first application, while investors are increasingly attracted to projects that promise to tap into a range of new revenue streams through the grid balancing services they can offer.

The analysis forms part of a new database, which will allow RenewableUK members to access comprehensive information on nearly 400 UK energy storage projects. It will show where operational projects are located on an interactive map, and highlight those projects in planning or under construction, including those sited alongside solar, wind and tidal energy projects.

The study also shows that improvements in battery technology mean the size of battery projects is increasing. The average capacity of applications for new battery storage projects has risen from 10MW in 2016 to 27MW today.

RenewableUK said that there is already 3.3GW of storage capacity, including hydro projects, operational in the UK and a further 5.4GW has planning consent, including 4.8GW of battery storage.

The data provides further evidence of the speed at which the UK power sector is transforming. Writing on Twitter, Green Alliance’s Chaitanya Kumar noted that 7GW of energy storage capacity would be higher than most National Grid projections for the sector in 2030.
