Working groups

As an ESA member, you gain the opportunity to actively contribute to the development of the UK’s energy storage sector through our specialist Working Groups. These groups bring together industry leaders, innovators, and technical experts to solve shared challenges, influence UK policy, and shape the standards that will define our industry for years to come.

By joining the ESA, you don’t just stay informed — you help drive the agenda. Our Working Groups are central to forming ESA’s policy asks, producing technical guidance, and ensuring the UK energy storage industry remains safe, secure, competitive and future‑ready.

Below are the current Working Groups open to ESA members:

working group 1

Cyber Security & Interoperability

This group is dedicated to developing practical, technically robust security solutions for modern storage systems. We focus on creating approaches that manufacturers can realistically adopt, ensuring improvements are both effective and achievable.

working group 2

Safety

This group brings together industry specialists to address the most pressing safety challenges facing installers, operators and insurers across the energy storage sector. With a focus on understanding how upcoming PAS reforms will integrate with new British Standards.

working group 3

Large-Scale & Long-Duration Energy Storage

Our LDES group is dedicated to exploring technologies that will underpin the UK's future energy resilience. As the grid evolves to accommodate higher volumes of renewable generation, long-duration and large-scale storage solutions are becoming essential.

working group 4

Policy & Regulation

This group plays a central role in shaping the future of the UK energy storage sector. Bringing together technical experts to ensure the regulatory landscape enables growth, supports innovation and recognises the critical role of storage in a net-zero energy system.
