Gore Street has signed a deal with Nidec ASI for the provision of engineering, procurement and construction (EPC) services for the 49.9MW Ferrymuir and 79.9MW Stony battery storage sites.

Both assets are one hour duration, beginning-of-life energy storage systems. Ferrymuir is located in county Fife, Scotland, while Stony is located close to Milton Keynes.

The contracts include the EPC arrangements and long-term service agreements for maintenance and operation, including availability and energy capacity warranties and stringent performance requirements to be demonstrated by Nidec ASI, Gore Street said.

Both assets are scheduled to be energised in Q4 2022, with both to achieve commercial operation in February 2023.

They will both operate in Dynamic Containment, firm frequency response and wholesale and balancing mechanism trading. They will also be able to participate in new services made available by National Grid and distribution network operators, according to the company.

Gore Street has recently been ramping up its international expansion plans, acquiring a 90% stake in a 28MWh operational energy storage asset in Cremzow, Germany and acquiring a portfolio of eight energy storage assets in Texas, US this month.

Meanwhile, in November it announced it would be exapanding its Kilmannock battery energy storage system in Co. Wexford, Ireland by 90MW, building on the 30MW already announced.
