Connected Energy to Build Major Second-Life Battery Testing Facility in the UK
Connected Energy, a UK-based specialist in Second-Life Battery Energy Storage Systems (BESS), has announced plans to construct a large-scale testing facility for used EV batteries at Scottow Enterprise Park in Norfolk, UK. Backed by an investment of approximately £2 million, the site is expected to be operational by mid-2026 and is positioned to become one of Europe’s most advanced testing infrastructures for "second-life" batteries.
Connected Energy, a UK-based specialist in Second-Life Battery Energy Storage Systems (BESS), has announced plans to construct a large-scale testing facility for used EV batteries at Scottow Enterprise Park in Norfolk, UK. Backed by an investment of approximately £2 million, the site is expected to be operational by mid-2026 and is positioned to become one of Europe’s most advanced testing infrastructures for "second-life" batteries.

The facility will feature a capacity of approximately 5 MWh and is designed to test and integrate batteries from electric buses and trucks from various manufacturers into grid-scale storage systems. The project's primary focus is to evaluate the technical performance of different cell types and deployment scenarios while demonstrating the economic viability of repurposing batteries after their automotive lifespan.
Through this project, Connected Energy aims to test a wide spectrum of retired batteries while generating critical data on how "end-of-life" EV batteries can generate revenue in stationary storage applications. This includes providing essential grid services such as energy arbitrage and grid flexibility. These insights will serve as the foundation for future large-scale commercial projects.
