Construction work has officially begun on SSE's largest battery storage project at Monk Fryston in North Yorkshire.

A groundbreaking ceremony for the 320MW facility was held on Tuesday, 08 October, with representatives from SSE Renewables, lead contractors Morrison Energy Services, and energy storage provider Sungrow in attendance to mark the occasion.


The project is SSE’s largest battery storage facility in construction and one of the largest of its kind in the UK. Once completed, the site could power over half a million homes for up to two hours at a time, during times of peak demand.

To mark this significant project milestone, SSE Renewables, Morrison Energy Services, and Sungrow have planted a ceremonial tree near the entrance to the site.

SSE’s first operational battery storage facility at Salisbury (50MW) entered full operations earlier this year, with a further two projects in construction at Ferrybridge (150MW) and Fiddler's Ferry (150MW).

With work at Monk Fryston now underway, construction is expected to be completed by early 2026.
