"Connected Energy is developing what it describes as the UK's most advanced second-life EV battery testing facility as part of its first wholly owned and operated battery energy storage system (BESS) site. The project marks a step change in the company's strategy, moving from delivering systems for third parties to owning and operating grid-scale storage assets. The site will be located at Scottow Enterprise Park in Norfolk, close to Connected Energy's technical centre. Alongside its role as a commercial energy storage installation, the facility will be used to test the integration and performance of batteries from multiple electric bus and truck manufacturers."
"At the core of the site will be a 5MWh BESS using second-life EV batteries. By trading energy and providing grid services, the installation will demonstrate how different battery types perform in applications such as energy arbitrage and flexibility services. The first batteries deployed at the site will be supplied by Forsee Power, as announced in May 2025, with additional partners expected to follow."
"The project is supported by the Advanced Propulsion Centre UK (APC) as part of a wider £2 million programme aimed at improving EV battery reuse and recycling. Once operational, the facility will also generate data on technical performance, grid behaviour and revenue generation to inform future, larger-scale second-life battery deployments."
Connected Energy will invest £2 million to establish a 5MWh second-life EV battery energy storage system (BESS) and testing facility at Scottow Enterprise Park in Norfolk, scheduled to open by mid-2026. The site will be the company's first wholly owned and operated grid-scale storage asset and will test batteries from multiple electric bus and truck manufacturers, with initial cells supplied by Forsee Power. The installation will trade energy and provide grid services such as energy arbitrage and flexibility, generate technical and commercial performance data, and inform future larger-scale second-life battery deployments. The programme is supported by the Advanced Propulsion Centre UK.
