A new report from the All-Party Parliamentary Group (APPG) on Energy Storage believes 12GW of battery storage deployment in the UK is possible by the end of 2021.

The Renewable Energy Association, the report’s authors, estimates that in 2016 only 0.06 GW of battery storage was installed and operational in the UK.

The report argues that increasing that 12GW of battery storage would have a positive impact on UK energy security, would support the creation of domestic battery manufacturing and would support the export of cutting-edge low-carbon products and services post-Brexit.

Given the current pace and nature of policy change, however, the group estimates that the “medium deployment” scenario, of 8GW of battery storage is more likely. The “low deployment” scenario, if minimal regulatory change occurs and barriers are erected to slow deployment, foresees 1.7 GW.

Improve energy security

Peter Aldous MP, Chair of the APPG on Energy Storage said:

“Significant battery storage deployment is possible if the Government keeps to the targets and timelines it has already set for encouraging electricity system flexibility.

“12 Gigawatts of battery storage would improve the UK’s energy security, would help us maximise our energy self-sufficiency, and empower consumers across the country as they are more able to manage their bills and take personal action to reduce carbon emissions.

Such a significant amount of battery storage deployment would also support the Government’s ambitions to develop the UK into a battery manufacturing powerhouse, evidenced in the Faraday Challenge funding announcements last week. Battery manufacturing would create new jobs and exportable expertise post-Brexit.

“Given the actual pace of policy change at present, however, we believe that it is more likely that a “medium” scenario of around 8GW of battery storage will be in place by the end of 2021.”

Dr Nina Skorupska CBE, Chief Executive of the Renewable Energy Association said:

“The UK Government and many in the industry significantly underestimated how cheap and popular solar PV was to become. Analysis at the start of the decade by the energy regulator, Ofgem, expected between 2GW and 7GW of solar to be deployed in the UK by 2030, instead over 12GW was deployed by the end of 2016. The technology and deployment patterns for battery storage and solar PV are similar, and this report is intended to drive big thinking and put the UK on the front foot, rather than react after-the-fact.”
