As the UK works towards a cleaner and more reliable energy system, one thing has become very clear: energy storage systems are essential. They allow the country to store surplus power, support the grid during peak demand and make full use of renewable energy.
This rapid expansion is creating new career pathways and a growing need for trained professionals. At SERT, we help people and employers build the skills needed to thrive in this fast-growing sector.
What Is an Energy Storage System?
An energy storage system captures electricity and stores it for use at a later time. This can involve batteries, mechanical storage such as pumped hydro or newer technologies like liquid air storage.
One of the fastest growing technologies is the battery energy storage system, often shortened to BESS. These systems use high capacity batteries to absorb energy when supply is high and release it when demand rises. This makes battery energy storage systems a vital part of a modern and flexible electricity network.
These systems support the UK by:
- storing excess renewable electricity
- delivering power quickly during peak periods
- helping maintain grid stability
- providing emergency back up
Why Energy Storage Systems Matter in the UK
1. Supporting the UK's Renewable Energy Targets
Experts state that energy storage is the only effective way for the UK to meet its renewable energy goals while dealing with the variability of wind and solar generation.
As the country increases its renewable generation, employers will need more workers who can install and maintain a wide range of energy storage systems.
2. Keeping the National Grid Stable
A battery energy storage system can react in milliseconds and help keep the National Grid stable. These systems absorb energy when wind and solar output rises and release it when demand increases.
This creates strong demand for:
- BESS installers
- grid support operatives
- monitoring specialists
- technicians supporting EV charging
The growth of electric vehicles is increasing the need for battery energy storage systems UK wide, especially at sites with limited grid capacity.
3. Long Duration Storage Projects Across the UK
The UK already operates major long-duration storage sites, including Dinorwig, Cruachan, Ffestiniog and Foyers. Together, these provide around 2.8 GW of storage capacity and are undergoing large refurbishment programmes.
New projects such as Coire Glas and Glen Earrach are in progress to expand long-duration capacity. These developments require skilled workers across electrical engineering, civil works, mechanical maintenance and safety.
4. Supportive Government Policy
Government legislation now defines electricity storage as a specific part of electricity generation, which helps simplify planning and supports faster deployment.
This creates confidence for investors and employers and increases demand for workers trained to operate and maintain battery energy storage systems along with other storage technologies.
