The ESN Winter Conference serves as a platform for key industry players and policymakers to come together and engage in debate over what’s needed to attract the billions of investments required for this crucial asset class – from supportive policy and regulatory frameworks, shifting revenue strategies, and evolving business models. 

We now have over 3.3 GW and 4.1 GWh of battery storage operational and GWs in construction.  Grid-scale electricity storage is well-established as key to a zero-carbon energy system, a testament to the success of our 85+ Electricity Storage Network members.  

You will hear directly from ESN members and key decision-makers – from DESNZ, Ofgem and National Grid ESO on the latest changes across a range of topics critical to the storage sector, including the Balancing Mechanism, grid connections, fire safety, and long-duration energy storage policy development. 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.

This replaces the Electricity Storage Network (ESN) Annual Conference usually held every January, established as one of the most popular industry events in the calendar leading the debate on the future of grid scale electricity storage.

    • What new services and market reforms are on the horizon?
