What is a battery energy storage system?

Battery Energy Storage Systems (BESS) are crucial for the energy transition, providing flexibility and stability to the grid. They store energy from renewable sources like solar and wind, and release it when needed, helping to balance supply and demand. In the UK we are due to energise our first two UK batteries, based in Scotland, in spring 2025.

Where is the UK's largest battery energy storage system?

The UK's largest battery energy storage system has gone live in North Yorkshire. Lakeside Energy Park is a 100MW facility in Drax, near Selby, which can provide power to about 30,000 homes a day across England and Wales.

What is Swansea north battery storage?

The project showcases a powerful network that combines rapid EV charging, hybrid battery storage, low carbon heating and smart energy management. The project provides a blueprint for towns and cities to cut carbon emissions and improve air quality. EDF Renewables UK is seeking local people’s views on the proposed Swansea North battery storage

Should I add battery storage to my site?

If you have space available for battery installations, and if you have more than 10 MW of spare capacity on your grid connection, you could benefit from adding battery storage to your site. Battery Energy Storage Systems (BESS) can offer several environmental advantages and therefore significantly impact the energy transition. A few of them are:

How much battery storage capacity is there in the UK?

Fig 1: There is over 440 GWh of battery storage capacity in the UK pipeline including 274 GWh (61%) at the pre-planning stage. Most of the projects are in the early stages: either announced by developers, included in the TEC register, or have screening/scoping applications submitted.

How much battery storage do the UK and Ireland need?

The UK and Ireland need over 25GW of battery storage by 2050. Our battery storage sites will provide up to 2GW of flexible capacity to accelerate the transition to a net zero future.
