Leading energy storage technology companies, developers, operators and outstanding individuals are featured on the shortlists for this year’s Energy Storage Awards (ESAs).
The Energy Storage Awards 2025, hosted by our publisher Solar Media, marks the third year of recognition and celebration of achievements across the energy storage industry in the UK, Europe, and the world. It will take place on 20 November 2025 at the Park Plaza London Riverbank.
Winners at last year’s ceremony included Developer of the Year Harmony Energy, System Integrator of the Year (for the second year in a row) Fluence, while developer-operator Zenobē’s Semih Oztreves won the Outstanding Contribution to Energy Storage Award.
As the industry has grown, so has the scale and breadth of the event. From last year’s 21 award categories, the 2025 edition has grown to 25 categories spread across five category groups: Innovation and Technology, Financial & Commercial, Individual & Leadership, Project Development and Industry Awards.
