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.
The company has around 1.2GWh of battery projects construction ready in the UK. Peter Kavanagh, CEO of Harmony Energy, said: “The completion of the Contego site is a significant milestone in the continued deployment of battery energy storage in the UK, representing our largest development to date and a significant contribution to the network.
The project is located next to a substation operated by UK transmission system operator (TSO) National Grid in the village of Monk Fryston. SSE Renewables has started building a 320MW/640MWh battery energy storage system (BESS), the largest under-construction in the UK.
SSE has officially launched construction on its largest battery storage project to date, a 320MW battery energy storage system (BESS) located at Monk Fryston in North Yorkshire. This facility is among the largest of its kind in the UK and is expected to power over 533,000 homes for up to two hours during periods of peak demand.
Ferrybridge is SSE Renewables’ second battery storage project under construction, with a 50MW BESS site at Salisbury due to be fully operational before the end of 2023. The business has also received planning consent for battery storage projects at Fiddler’s Ferry (150MW) and Monk Fryston (320MW).
Field is to break ground at its Newport battery storage site in South Wales in the coming weeks. The renewable energy infrastructure company has signed contracts with two key partners to construct the 40 MWh site, which will contribute to the UK’s efforts to decarbonise energy supply.
