The 49.9 MW Pelham project was constructed in six months by British Solar Renewables EPC (BSR EPC) for SMA Sunbelt Energy, a subsidiary of SMA Solar Technology.
The project, located near Bishop’s Stortford in England, was originally developed by British storage and flexible power firm Statera Energy, which owns and operates the site. The project was recently re-financed, which was a first for UK large-scale battery storage re-financing.
The 4500 m2 facility houses batteries and other equipment in custom-built prefabricated buildings, which SMA says reduces the site’s footprint by up to 50 per cent when compared with designs the use shipping containers.
The site comprises seven of the prefabricated buildings, 27 inverters, 12 km of cable and 150,000 lithium-ion battery cells. It is connected to a nearby 400kV substation via a 132kV grid connection.
Tim Humpage, BSR’s head of engineering, procurement and construction, said: “Renewables are meeting more and more of our energy needs, and projects like this have the power to turbo-charge this trend, as batteries have the ability to balance supply and demand. Energy storage facilities such as this will an essential part of the transition to a low carbon environment in the coming years”.
