DIFFERENT TYPES OF BATTERY STORAGE UK
UK energy storage battery applications
Depending on the number of applications submitted in December, 2024 could be set to be the first year since 2018 where the number of applications has not surpassed the previous year; there would need to be more than 100 projects submitted to eclipse the total of 2023. 2024 is also set to see a small decrease in the average capacity of the projects being submitted, currently a 5MW decrease from 71MW in 2023 to 68MW in 2024 year-to-date.

What is a battery energy storage system?
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.
How many battery energy storage systems are there 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.
Why is battery storage so important in the UK?
The capability of these technologies to support renewables, support grid stability, and help deliver flexible energy storage is especially pertinent. By early 2025, there will be phenomenal growth in battery storage capacity taking place in the UK: Operational capacity: Around 5 GW of battery storage capacity is operational.
Why is battery energy storage important?
Battery energy storage is becoming increasingly important to the functioning of a stable electricity grid. As of 2023, the UK had installed 4.7 GW / 5.8 GWh of battery energy storage systems,1 with significant additional capacity in the pipeline. Lithium-ion batteries are the technology of choice for short duration energy storage.
Which batteries are used in energy storage?
Although recent deployments of BESS have been dominated by lithium-ion batteries, legacy battery technologies such as lead-acid, flow batteries and high-temperature batteries continue to be used in energy storage.
What is a battery energy storage system (BESS)?
Batteries are installed as battery energy storage systems (BESS), where individual battery cells are connected together to create a large energy storage device (Box 1). The size of a BESS is defined by its power capacity and its stored energy capacity (Box 2).
Mainstream battery types for energy storage
Electrochemical energy storage involves various types of battery energy storage systems. Batteries convert chemical energy into electrical energy. The two most common types are rechargeable batteries and flow batteries. [pdf]
