Utility-Scale BESS Construction Accelerates Across the EU
The European utility-scale battery storage sector is witnessing a wave of massive project developments. In Germany, Trianel, Luxcara, and BKW held the symbolic groundbreaking ceremony on September 21, 2026, for a colossal 900 MW and at least 1,800 MWh battery storage project in Waltrop, North Rhine-Westphalia. Built on a former construction site near the Trianel Lünen coal-fired power plant, the facility has secured grid connection confirmation from transmission system operator Amprion.
Strategic Partnerships and Capacity Allocation
The Waltrop project features a robust partnership structure. Independent asset manager Luxcara holds the largest single share at 520 MW, Swiss energy company BKW holds 300 MW, and Trianel subsidiary T-BESS holds 80 MW.
Dutch and Belgian Mega-Projects
In the Netherlands, RWE has taken a final investment decision to develop a 400 MW/1,100 MWh lithium-ion BESS at its Moerdijk power station. Scheduled for commissioning in Q2 2028, the project will utilize 208 battery containers and operate under capacity steering agreements with Dutch TSO TenneT, supporting the integration of the 795 MW OranjeWind offshore wind project.
Meanwhile, in Belgium, Giga Storage has commenced construction on the 'Green Turtle' project. This 700 MW / 2.8 GWh system will be one of Europe's largest, utilizing 640 Tesla Megapack 3 units. Backed by secured financing, it is expected to be commissioned in March 2028 and will connect to a new 380-kV substation built by grid operator Elia.
These mega-projects highlight the critical role of large-scale BESS in relieving grid congestion and integrating offshore and onshore renewable generation across the EU.
