Anticipated acquisition of 100MW project, part of the new project pipeline

Gresham House Energy Storage Fund plc (LSE: GRID), the UK's largest fund investing in utility-scale battery energy storage systems (BESS), is pleased to announce the signing of a Sale and Purchase Agreement for the conditional acquisition of a 100MW battery project in Elland in West Yorkshire ("Elland 2").

Elland 2, which is being designed to a 2-hour duration and is extendable to a longer duration in due course, is one of the projects detailed in the new project pipeline set out in the Company's Three-Year Plan and 2025 Interim Report. The project is adjacent to the operational Elland 1 site already owned by the Company, which offers efficiencies across the two sites.

The acquisition is conditional on, among other things, the Company confirming it is satisfied that the project will receive or has received an acceptable Gate 2 connection offer, which is expected to occur by the end of March 2026 at the latest. The confirmation and grid connection offer will be received through the ongoing Queue Reform process which is being managed by the National Energy System Operator (NESO).

Ben Guest, Fund Manager of Gresham House Energy Storage Fund plc & Managing Director of Gresham House Energy Transition, said: 

"The acquisition of Elland 2 is a major step in the Three-Year Plan. Elland 2 is an area we know well, having built the neighbouring Elland 1 project which energised in November 2024. We aim to begin construction of Elland 2 within the next few months and will be procuring long lead items in the meantime. Once finished, this project, with a capacity of 100MW/200MWh, will be larger than any other in the current operational portfolio."

Definition of utility-scale battery energy storage systems (BESS)

Utility-scale battery energy storage systems (BESS) are the enabling infrastructure that will support the continued growth of renewable energy sources such as wind and solar, essential to the UK's stated target to reduce carbon emissions. They store excess energy generated by renewable energy sources and then release that stored energy back into the grid during peak hours when there is increased demand.
