Technical FAQs 4

Could a battery storage system save the UK energy system?

The UK government estimates technologies like battery storage systems – supporting the integration of more low-carbon power, heat and transport technologies – could save the UK energy system up to £40 billion ($48 billion) by 2050, ultimately reducing people’s energy bills.

How big is battery energy storage in the UK?

The UK had a total of 4.4GW of battery energy storage system (BESS) capacity as of June 2024. And the sector is braced for further significant growth, with the total capacity of projects in the pipeline rising from 50.3GW to 95.6GW between 2023 and 2024.

What are the UK's largest energy storage projects?

Bramley BESS (Hampshire): 100 MW / 331 MWh, currently the UK’s largest energy storage project. Fidra Energy (Thorpe Marsh): A 1.4 GW / 3.1 GWh BESS being built on a former coal site. Copenhagen Infrastructure Partners (CIP): Two 500 MW / 3 GWh systems planned in Scotland.

What technologies are behind UK energy storage?
