SSE has purchased the project development rights for its first 50MW battery storage asset on a consented site in Wiltshire, from Harmony Energy Limited.

SSE plans to bring the project to financial close and construct the battery storage facility at Salisbury over the next 18 months. The project will help deliver essential balancing services to the energy system.

SSE’s distributed energy division has a team of developers, engineers, and energy service professionals actively growing its battery storage pipeline.

Harmony Energy Limited is a developer of utility-scale battery energy storage projects. It has developed two projects in the UK, with a pipeline of over 600MW of project rights.

As we put more renewable energy on the grid and phase out fossil fuels, battery storage has a key role to play in helping the UK decarbonise. “Our distributed energy division has ambitions to build a significant portfolio of batteries – we’re looking at around 500MW of early stage opportunities – and we hope today’s announcement signals the seriousness of our intent in this market.” Peter Kavanagh, CEO of Harmony Energy, said: “The site has been four years development work in the making, demonstrating our expertise in bringing forward complex battery storage developments to construction-ready stage.

It’s great for SSE to have shown their confidence and enable our divestment. We share their vision and passion to help accelerate the deployment of energy storage which is fundamental to the UK’s energy mix and enabling the reduction of carbon emissions.
