Industry executives from owner-operators BW ESS, Eku Energy, Gore Street, Field and NEOM answered questions from the audience on Day One of last month’s Energy Storage Summit EU 2025.

Independent power producer (IPP) RWE has commissioned a 35MW/41MWh BESS in the Netherlands, while commissioning is progressing on a smaller system with grid-forming capabilities.

February 2025 saw around 4.5GW/10.5GWh of grid-scale BESS deployments globally, with China continuing to account for the majority but Europe increasing its share from January.

MW Storage has enlisted optimiser Entrix to commercialise 50MW/100MWh of the capacity of a project twice that size in the town of Arzberg, Germany.

We hear from startup Volklec which, like another European battery company Elinor, will build its batteries with a Chinese technology and manufacturing partner. They both say this will get around the challenges that ultimately doomed Europe’s first wave of battery startups, with Northvolt today declaring bankruptcy in Sweden.

We caught up with a partner at insurance broker Lockton about recent developments in the space, including the ramifications – or lack thereof – of the recent Moss Landing fire on insuring BESS projects going forward.

Renewco Power and Atlantica Sustainable Infrastructure will develop and build a pipeline of BESS projects in Spain.

Sweden-headquartered BESS developer-operator Ingrid Capacity will build a 70MW/140MWh project in Finland, which it claimed will be the largest in the country.

ESN Premium speaks with Anna Darmani, energy storage analyst at Wood Mackenzie, about Europe’s sector evolution.

The UK now has nearly 9GWh of grid-scale BESS online, with more than double that figure under construction.
