Will energy storage help UK meet net zero by 2050?

Energy storage will be a significant enabler of the renewable energy adoption required for the UK to meet net zero by 2050, National Grid ESO said. Image: National Grid.

How big is battery energy storage in the UK?

Currently in the UK, there is 1.6 GW of operational battery storage capacity mostly with 1-hour discharge duration, i.e. 1:1 ratio of energy to power, GWh to GW. The maximum installed volume of PHS is 25.8 GWh with 2.74 GW of capacity, a much higher ratio. In recent years, there has been a surge in the pipeline of battery energy storage projects.

What is long-duration energy storage?

Long-duration energy storage technologies store excess power for long periods to even out the supply. In March 2024, the House of Lords Science and Technology Committee said increasing the UK’s long-duration energy storage capacity would support the UK’s net zero plans and energy security.

Why does the UK need long-term energy storage?

In May, the predecessor Environmental Audit Committee (EAC) warned that the lack of long-term energy storage in the UK was driving the importation of gas so as to balance the nation’s energy needs. Market, policy and regulatory barriers were all holding back the development of long-term energy storage.

How many GW of prequalified battery energy storage systems are there?

Out of 6.9 GW of prequalified battery energy storage systems (BESS), equal to 1.9 GW derated capacity, about 1.8 GW of derated BESS secured 15-year contracts in the UK’s T-4 auction – nearly double last year’s volume. Just a week earlier, the T-1 auction also set a record for BESS procurement. From ESS News

What role does energy storage play in the energy landscape?

Kelly Loukatou, one of the ESO’s energy insight leads, considers the role energy storage plays in the current energy landscape and how this is likely to develop. Energy systems need to continuously match supply and demand to ensure that electricity is delivered securely to UK houses and businesses.
