Battery energy storage system in Uk

As renewable capacity is added to the grid, the need to store and flexibly manage electricity grows with it. This is where the crucial role of battery energy storage systems (BESS) come into play, storing and releasing energy for when it's needed most. We look at what's happening with the growth of BESS in the UK.

Towards the end of 2023, the UK had 3.5GW of battery storage capacity. That's 3,500,000 watts. Although a large number, this is still very small in the grand scheme of things. At the time of writing, there are over 1,000 battery energy storage system (BESS) projects in the pipeline. These are growing in size too.

As the UK intensifies its focus on decarbonising the electricity system, timely grid access for battery storage will be essential to support renewable energy integration, grid stability and meeting emission reduction targets.

Scotland is hosting three of Europe's largest battery energy storage systems: Projects: Coalburn 2 in South Lanarkshire, Devilla in Fife and Coalburn 1 are already under construction. Capacity: Co-located total power capacity of 1.5GW and 3 GWh of energy storage capacity. Timeline: Effective by 2027-28.

Recent Additions: In the fourth quarter of 2024, 381 MW of battery capacity was connected to the grid alone, the largest quarter growth of capacity, overall. There is great potential for the growth of battery storage capacity in the UK: 2030 Targets: The UK has a target to increase battery storage capacity to 27-30 GW by 2030.

By definition, a Battery Energy Storage Systems (BESS) is a type of energy storage solution, a collection of large batteries within a container, that can store and discharge electrical energy upon request.
