Battery energy storage systems are a proven low-cost technology which uses groups of batteries to store excess electricity from renewable energy sources. This electricity is released to homes and businesses when needed.
Thorpe Marsh Green Energy Hub is currently the largest battery storage project in the UK.
Once complete it will have capacity to power 800,000 homes helping to make the electricity network in the UK and Yorkshire more secure, self-sufficient and resilient.
