Summary

In this episode of Energy Unplugged, Tom Palmer, Head of Business Development at Zenobē, discusses the growing role of large-scale battery storage in the UK’s power grid. He highlights the trend towards larger and longer-duration batteries, driven by investor confidence and technological advancements. Palmer addresses operational challenges, particularly high skip rates in the Balancing Mechanism, which prevent batteries from being utilized effectively, wasting potential savings for consumers. He advocates for improvements in the system operator’s processes and the Open Balancing Platform. The conversation also covers grid-forming technology, which allows batteries to provide stability services traditionally supplied by synchronous generators, and the commercial landscape, including investor appetite and the impact of connection reforms. Palmer emphasizes the versatility of batteries as a ‘Swiss Army knife’ for grid services and the need for regulatory and market reforms to fully realize their potential.
