Monk Fryston is a 320MW capacity battery energy storage system (BESS) based in the Selby district of North Yorkshire. SSE Renewables took a final investment decision on the project in November 2023, with construction due to begin in spring 2024.

SSE Renewables will partner with Morrison Energy Services and Sungrow to deliver the Monk Fryston BESS project.

Once complete, the site will be one of the largest battery energy storage systems in the United Kingdom, capable of powering approximately 533,000 homes for up to two hours at a time*.

Project history and progress

Monk Fryston was selected as a suitable site for development due to its location, adjacent to National Grid’s Monk Fryston substation and less than two kilometres from Junction 42 of the A1(M).

By directly connecting the battery to the existing transmission network without the need for additional grid infrastructure, SSE Renewables can minimise the built infrastructure impact on the surrounding environment.

SSE Renewables will continue to liaise with the neighbouring community to ensure construction is completed as efficiently and safely as possible.
