Mitie Power & Grid and Elements Green have commenced construction on a £71.5 million battery energy storage system (BESS) in Staythorpe, Nottinghamshire, marking a significant step in the UK’s renewable energy infrastructure.
Once operational in mid-2027, the 360MW/720MWh facility is expected to store enough electricity to power more than 95,000 homes for a full day. The project is among the largest of its kind in Europe and is designed to support the UK’s renewable energy ambitions.
Mitie, through its G2 Energy subsidiary, is responsible for the design and construction of both the battery system and an associated 400kV grid substation. Elements Green is managing the environmental aspects of the project, aiming to deliver a 25.7% biodiversity net gain by establishing new woodland areas, wildflower meadows, and tree planting initiatives.
Approximately 60 jobs are expected to be created during the construction phase, with the project designed to operate for at least 40 years.
“Staythorpe BESS is a perfect example of how we apply our infrastructure expertise to accelerate the UK’s transition to clean energy,” said Mark Caskey, managing director of Mitie Technical Services. “This project will create real value for local communities.”
Elements Green chief executive Rasmus Friis noted the importance of community collaboration, stating, “This development is about more than storing clean energy – it’s about working hand in hand with our neighbours to deliver lasting value.”
UK Energy Minister Miatta Fahnbulleh welcomed the initiative, saying, “Battery storage will help protect homes and businesses from price shocks by unlocking our renewable power potential.”
The Staythorpe site is part of broader national efforts to increase energy security and grid flexibility amid rising demand for low-carbon power sources.
