Independent power producer (IPP) RWE has commissioned a 35MW/41MWh BESS in the Netherlands, while commissioning is progressing on a second that will have grid-forming capabilities.
The 1.17-hour battery energy storage system (BESS) in Eemshaven is the company’s first in the Netherlands and will balance supply and demand on the Dutch grid, RWE said. It is comprised of BESS units from CATL comprising a total of 110 lithium iron phosphate (LFP) battery racks, and construction started a little over a year ago.

The firm also said that commissioning is ongoing for its second project in the Netherlands, a 7.5MW/11MWh system with ultra-fast synthetic inertia capabilities, a type of grid-forming application. RWE said it would be one of the first of its kind installed on mainland Europe. A 200MW/400MWh grid-forming BESS was commissioned by Zenobe in Scotland earlier this month.
The two BESS projects are part of a wider system integration project for the 795MW OranjeWind offshore wind project by RWE in partnership with the IPP arm of oil and gas major TotalEnergies. The OranjeWind project is establishing new ways to integrate renewables into the Dutch energy system, including with electrolysers, smart charging stations for electric vehicles (EVs), electric boilers, and BESS.
The energy storage market in the Netherlands has progressed substantially in the past 18 months. At the start of 2024, grid fees were made more flexible, significantly improving the potential business case for storage.
Following that, a swathe of large-scale projects were financed or progressed, and, most recently, last month Lion Storage reached financial close on a 350MW/1,400MWh BESS, one of the largest in Europe to do so. A few weeks before that, the first 4-hour system, at 10MW/40MWh, came online.
Held alongside the Battery Show Expo Europe in Stuttgart, Energy Storage Germany spotlights Germany’s rapid ascent in the European storage sector. Once driven by residential demand, utility-scale projects are now surging, with 184 MW added across 44 projects in 2023. With nearly 16 GWh of capacity installed in the first half of 2024, Germany is set to integrate 24 GW of utility-scale energy storage by 2037, creating substantial opportunities.
The UK & Ireland is the most mature and established energy storage market in Europe, with just over 5GW of total operational capacity at the start of 2025. With over 130GW in the pipeline for the UK and Ireland, the growth potential of this market is immense. With this in mind, everyone is asking, ‘how best to maximise battery assets?’ This event has established itself as a key industry platform, bringing together asset owners with the experts who can provide the answers – from optimisers and software providers to O&M specialists and more. The summit will equip the industry for the future, delving into the key pillars of asset management, exploring operational challenges, and spotlighting the latest developments in optimisation and software innovation.
Across two packed days, the Summit focused on three core themes: revenue & trading, the lifecycle of the battery, and optimisation tools. Attendees explored innovative strategies for enhancing asset performance and longevity, with a spotlight on key markets like Germany, Italy, and the UK. Stay tuned for details on the 2025 edition of the Battery Asset Management Summit Europe, where we’ll continue to chart the path forward for energy storage asset management.

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.
