The facility is also the first large-scale battery storage project in the country that has received re-financing.

“Energy storage facilities such as this will play an essential part of the transition to a low carbon environment in the coming years.”

BSR EPC was selected by SMA Sunbelt Energy (SMA), a fully owned subsidiary of SMA Solar Technology, specialised in large-scale battery storage projects.

Located near Bishop’s Stortford, the Stocking Pelham battery storage facility has been designed to deliver more than 60MVA of power.

It was originally planned by Statera Energy, a developer of flexible electricity generation and storage capacity and also the owner and operator of the site.

BSR EPC head Tim Humpage said: “We are delighted to have worked closely with SMA to deliver this landmark project.

“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 play an essential part of the transition to a low carbon environment in the coming years.”

Spread across 4,500m², the facility features seven E-houses, 27 inverters, 12km of cable and 150,000 lithium-ion battery cells and is connected to a nearby 400kV substation via a 132kV grid connection.

The project uses SMA’s proprietary E-house design, which has been designed to accommodate batteries and other equipment in custom-built prefabricated buildings in order to reduce the site’s footprint by nearly 50% in comparison to the designs using shipping containers.
