What is battery storage?

A battery storage system can be charged by electricity generated from renewable energy, like wind and solar power.

The battery software then uses algorithms to coordinate energy production and the control system decides when to store energy or to release it to the grid. 

Batteries can store the increasing levels of renewable energy generated from sources like solar farms and wind turbines when they are in surplus. Batteries can then supply the stored power back to the Grid when it is needed the most, helping to manage peaks of energy demand.

This means we can balance energy supply and demand more effectively and maximise the potential of renewable technology to power the Grid, even when the sun is not shining, or the wind is not blowing.

Ferrybridge BESS

Ferrybridge is a legacy SSE coal power station which was closed in 2016. SSE Renewables are developing a 150MW / 300MWh battery energy storage system (BESS) site on the land in West Yorkshire.

Fiddler's Ferry BESS

Located on the site of a former SSE-owned coal power station, SSE Renewables have a 150MW / 300MWh battery energy storage system (BESS) project under development in the Fiddler's Ferry near Warrington, Cheshire.

Salisbury BESS

Our first battery storage project in Salisbury, Wiltshire was completed in September 2023. The 50MW / 100MWH battery energy storage system (BESS) project was developed in conjunction with Wartsila and construction began in December 2022.

Richfield Solar and BESS

SSE Renewables is proposing to develop a c.21MWp solar PV array (solar farm) on lands near the existing 18-turbine Richfield Wind Farm in, County Wexford. The Richfield Wind Farm has been in operation since 2006 and can power almost 18,000 homes and helps to abate almost 22,000 tonnes of harmful carbon dioxide per annum.
