The commercial solutions arm of UK utility SSE will optimise a 250MW/375MWh BESS for developer-operator Pacific Green.

Under the terms of the agreement, Pacific Green will be responsible for the construction, operation and maintenance of Sheaf Energy Park, while SSE will provide optimisation services for a ten-year period from the start of commercial operations.

It is anticipated that commercial operations will commence in July 2025 and have an operating life of 35 years.

Sheaf Energy Park will be based in Kent next to Pacific Green’s first BESS development created under a framework agreed with TUPA Energy, dubbed Richborough Energy Park. Pacific Green recently secured a combined £123.5 million facility from NatWest and the UK Infrastructure Bank (UIB) for the Sheaf Energy Park at the start of November.

Scott Poulter, Pacific Green’s chief executive, said: “SSE is one of the UK’s most prominent and reliable energy providers, and we are thrilled to have them trading Sheaf Energy Park for the foreseeable future. Southeast England is an extremely dynamic part of the country’s electrical grid, so partnering with an experienced operator such as SSE will be a big asset towards Sheaf Energy Park’s success.”

Pacific Green is also active elsewhere in Europe, recently buying a 4-6 hour BESS portfolio in Italy and securing land for a potentially 1GWh project in South Australia.
