Statera Energy has welcomed Ofgem’s minded-to decision to include three of its projects in the Long Duration Electricity Storage (LDES) cap and floor regime, marking a major step forward for the UK’s ability to store clean power when it is abundant and release it when the system needs it most.
Loch Kemp Storage, Sundon Storage and East Claydon Storage have been selected as part of a portfolio of 16 projects that Ofgem is proposing to support. Together, they represent around 1.6GW of flexible capacity, accounting for over 20% of the total identified in the scheme. Ofgem’s announcement reflects growing recognition of the role that long-duration flexibility will play in maintaining system stability and managing demand over extended periods.
Statera’s Loch Kemp Storage, a pumped storage hydro project on the shores of Loch Ness, was ranked first overall in Ofgem’s economic assessment. Pumped storage hydro is one of the most proven and dependable forms of long-duration storage, with long operating lifetimes and the ability to provide system support over extended durations. Once built, Loch Kemp will be the first new scheme of its kind delivered in the UK in 40 years, capable of powering around one million homes.
Statera’s battery projects at Sundon and East Claydon will deliver 1GW of capacity, providing the flexibility needed to balance the electricity system. Combined, the two sites will power around 3.2 million homes, with Sundon delivering eight hours of storage and East Claydon up to 12 hours.
Beyond their direct benefits, the projects are expected to support around 2,000 jobs at peak construction and strengthen UK supply chains, helping build domestic capability in energy infrastructure.
Tom Vernon, CEO of Statera Energy, said, “We’re very pleased that Loch Kemp, Sundon and East Claydon have been selected in Ofgem’s minded-to portfolio. As more renewable generation connects to the grid, long-duration energy storage will be essential for storing surplus electricity and delivering it when it is needed most.
“Together, these projects would add 1.6GW of flexible capacity, marking a major step forward in Statera’s role in delivering the storage infrastructure the UK will need in the years ahead.
“The LDES scheme represents a significant opportunity to help build a more flexible and resilient energy system, while creating jobs, strengthening UK supply chains and supporting local communities. We look forward to working with Ofgem, DESNZ and our partners to bring these projects forward.”
