Our Electricity Storage Network (ESN) Annual Conference will return on 25 November 2026 at the IET, London.
The conference is a platform for key industry players and policymakers to gather and debate what’s needed to attract and maintain the billions of pounds of investment required for this crucial asset class, from supportive policy and regulatory frameworks to shifting revenue strategies and evolving business models.
This is also an opportunity to learn about the ESN’s work to ensure policy, markets and regulation are geared to enable the storage sector to flourish and grow at the pace and scale required, plus plenty of networking time with 300+ industry leaders.
What did our 2025 attendees think?
“Regen's reputation as being an independent and trusted voice of the industry means that all the key players want to be in the room - and the government officials must think the same too as they also always show up.”
“I felt like it was one of the most gender diverse events I've been to, so again I think your initiatives are working.”
“I really do think it is one of (if not the!) best industry event of the year, and I had a couple of other people come up to me yesterday and say the same thing. A lot of people also spoke highly of the working groups - that they're not just talking shops and they're also friendly, accessible groups.”

The Electricity Storage Network Annual Conference is a platform for key industry players and policymakers to gather and debate what’s needed to attract and maintain the billions of pounds of investment required for this crucial asset class – from supportive policy and regulatory frameworks to shifting revenue strategies and evolving business models.
With over 5 GW of grid-scale battery storage operational and a 3 GW pipeline of new pumped hydro storage projects, plus other technologies in development, grid-scale electricity storage is established as key to a zero-carbon energy system – a testament to the success of our 100+ members.
And with an ambitious Clean Power 2030 action plan for accelerated clean power, against the backdrop of significant grid connection and market reform, and a long duration energy storage cap and floor scheme, the role of storage and flexibility is more important than ever.
At the ESN Annual Conference you’ll hear directly from our members and key decision makers from the Department for Energy Security and Net Zero, Ofgem and the National Energy System Operator on the latest changes across a range of topics critical to the storage sector, including Clean Power 2030, the revenue environment, long duration energy storage, grid connection reform and fire safety.
This is also an opportunity to learn about the ESN’s work to ensure policy, markets and regulation are geared to enable the storage sector to flourish and grow at the pace and scale required while networking with 300+ industry leaders in central London.
