Battery storage systems can import and store electricity from the National Grid and dispatch this stored electricity as needed to balance the network. This is particularly complementary to renewable energy sources such as solar and wind, which generate intermittent power based upon local weather conditions. Battery storage systems allow this energy to be stored for use in times of higher demand.
Introduction
Our Proposals
The proposal is for a 49.9MW battery storage project and associated infrastructure. More information will be available on the website once we have been through the full design process which is to take place over the next few months.
Changes since the last update:
- Detailed design of site access has been completed to account for level changes
- BESS compound has been raised on a platform (min. level 87.5mAOD, between 1-1.8m from current ground level depending on position within the site)
- The proposed construction compound area has been moved to the east of the site
- The welfare facilities and parking have been moved to the north of the compound
- The no. of BESS units has been reduced from 68 to 52 whilst still achieving 49.9MWac

Why is this project needed?
As fossil fuel sources of electricity (such as coal-fired power stations) are decommissioned, new renewable sources of dispatchable power need to be constructed. These will not only replace existing dispatchable power but will also help to support the optimal use of renewable energy sources such as solar farms and wind turbines which provide power intermittently based on local weather conditions.
Battery storage provides a way to store excess energy generated from renewable energy sources for use at times of higher demand but lower solar irradiation and / or wind generation. Batteries are able to import and store electricity from the National Grid network and export electricity when needed.
This 49.9 MW battery storage project could have a storage capacity of up to 199.6 Megawatt Hours (MWh) per full charge depending on the technology used. At full power output, this facility would therefore be able to generate for four hours, contributing to security of supply for our power system over the peaks in demand throughout the day.
For comparison, the average UK household uses around 3.7MWh of energy across an entire year and around 10 kWh per day, with a maximum instantaneous usage of around 0.8kW. On this basis, a single full charge could provide sufficient energy to power around 20,000 homes for a day, or provide instantaneous power to over 62,000 homes. In reality this energy storage facility will be used to provide services and balancing capability to the wider National Grid network, and operate dynamically in the GB energy market.
