On behalf of our members, we support the NESO proposals in the Frequency Risk and Control Report (FRCR) report 2025 that highlight the critical role fast-acting battery storage is playing in enhancing energy resilience and contributing to consumer savings of over £258 million.
The Electricity Storage Network has submitted its response to the 2025 FRCR Ofgem consultation, supporting key proposals and calling for changes to ensure storage can continue playing its vital role in energy system security. The world-leading frequency response services, managed by NESO and delivered by battery storage, continue to enable the clean energy revolution in GB and help deliver Clean Power 2030, while reducing costs for consumers. The maturity and liquidity in these critical system services provides NESO the ability to move forwards and propose further reductions in the minimum level of system inertia, while maintaining a secure energy system.
We welcome and agree with NESO’s proposals to:
