4 FAQs about UK energy storage project approval time

How many battery energy storage applications have been filed in the UK?

More than 100 planning applications for battery energy storage systems were filed in the UK between April and June 2025, covering a combined 8.4GW of capacity. That is more than twice as much as in the same quarter last year.

What is the UK's largest battery energy storage system (BESS)?

The figure comes from Solar Media Market Research's Battery Storage: UK Pipeline & Completed Assets Database report. It is the most large-scale battery energy storage system (BESS) approvals by capacity since July, when around 5GW/10GWh was given the go-ahead by either local authorities or central government.

How many GW of battery energy storage systems were proposed?

It drew 171 proposals totalling 52.6GW of discharge capacity. Li-ion battery energy storage systems (BESS) dominated the initial submissions with 112 projects, making up nearly three-fourths (38.6GW) of the total proposed capacity.

How many GWh of power has been approved in 2025?

Regarding full applications, over 1.6GWh of capacity has been submitted so far in 2025, an increase of 10% compared to the same period last year. Over 43GWh was approved in 2024, an increase of 35% from 2023 and this year has already seen over 8.9GWh of approvals, including one of the largest consented projects in the UK so far.
