NatPower UK has announced plans to invest more than £10 billion in a national portfolio of battery energy storage systems and grid infrastructure, as part of a strategy to support the UK’s energy transition and address long-term grid constraints.
The company said it is currently developing 13 battery projects with a combined capacity of 12.5 gigawatts (GW) and 100 gigawatt-hours (GWh) of storage. Ten of the assets are being assessed under Ofgem’s Long Duration Energy Storage (LDES) Cap & Floor Window 1 process.
Among the largest projects is the proposed 1GW Teesside GigaPark, to be located at Sembcorp’s Wilton International site. NatPower said the facility will be the UK’s “largest and most advanced” battery energy storage project, designed to provide grid balancing services and support the electrification of nearby port operations.
Other developments are planned across strategic locations in Yorkshire, Wales, the Midlands, and the south east of England.
The company also plans to invest in new 400kV substations and supporting transmission infrastructure aimed at relieving grid bottlenecks, reducing system costs, and easing pressure on existing network assets.
“With 12.5GW and 100GWh of battery storage in development, NatPower UK is delivering the infrastructure Britain needs to decarbonise at pace,” said Stefano Sommadossi, chief executive of NatPower UK.
“Our storage fleet is future-proofed as, contrary to the vast majority of current developments, it allows long duration storage and full augmentation,” he added. “It doesn’t just cut carbon, it reduces energy costs, eliminates inflation, strengthens the grid and ensures consumers and communities benefit from the clean energy transition.”
The investment forms part of a broader push to accelerate low-carbon energy deployment in the UK and meet national net zero targets by 2050.
