Dutch long-duration energy storage (LDES) developer Elestor has partnered with Windpark Zeewolde to deploy a 20MW/200-800MWh hydrogen-iron flow battery storage system at what is described as Europe’s largest onshore wind farm.
Tank storage company Vopak has marked its energy into the BESS sector with a final investment decision (FID) for a 200MW/800MWh BESS in the Netherlands, which recently entered into a first-of-its-kind agreement with TSO TenneT.
Octopus Energy Generation has partnered with ZE Energy to invest in and build one of Italy’s biggest BESS projects, while Eco Stor has secured financing for one of Germany’s, which it is already building. Optimiser Entrix has also won two large contracts in Germany and the Netherlands.
IPP Greenvolt has put a 99.8MW/288.6MWh BESS into commercial operation in Hungary, the largest in the country, while pipelines and projects have been progressed in Italy, France, Netherlands, Belgium and Spain.
Large-scale BESS projects have been progressed to construction, financing or operations across the EU this week, by project owners, investors and EPC firms re:cap, LONGi, Teos, Flower, Goldbeck Solar, SPP and Tavion.
How can energy storage capitalise on energy price volatility in European markets, and how do investors need to think about future opportunities and challenges? An expert panel at the Energy Storage Summit 2026 in London in February dived into the topic.
Dutch TSO TenneT has signed a contract with a developer for a large-scale BESS which will help to relieve grid congestion, possibly enabling the quicker deployment of renewables in the Netherlands.
