BSR EPC constructs one of the UK’s largest battery storage facilities

Flagship project, Stocking Pelham capable of delivering more than 60MVA of power

BSR EPC completed construction of the 49.99MW battery storage project in December 2017, in under six months, following selection by SMA Sunbelt Energy GmbH (SMA), a fully owned subsidiary of SMA Solar Technology AG specialised in large scale battery storage projects.

The project is located near Bishop’s Stortford and was originally conceived by Statera Energy, a developer of flexible electricity generation and storage capacity, who own and operate this site. The project was recently re-financed, making it not only the largest constructed battery storage facility in the UK but also a first for UK large-scale battery storage re-financing.

The 4,500 m2 facility uses SMA’s proprietary E-house design, which houses batteries and other equipment in custom-built prefabricated buildings. This method reduced the site’s footprint by up to 50% when compared with designs using shipping containers.

The site comprises 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.

Dr.-Ing. Enrique Garralaga, Head of Project Development at SMA, said: “We have decided to work with BSR EPC as principal contractor because of its experience of building large scale projects in tight timescales in the UK.”. BSR EPC’s project scope included both civil and electrical design, and subsequently construction and battery installation.

Tim Humpage, BSR’s Head of EPC (Engineering, Procurement and Construction), 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 an essential part of the transition to a low carbon environment in the coming years”.
