RWE has officially commissioned its first large-scale Battery Energy Storage System (BESS) in the Netherlands at the Eemshaven power station. With a total capacity of 35 megawatts (MW) and a storage capacity of 41 megawatt hours (MWh), the system will be crucial in balancing the power supply and demand within the Dutch electricity grid. k1p6u

The inauguration ceremony, held today at Eemshaven, was attended by RWE's Chief Operating Officer (COO) for Generation, Marinus Tabak, and Henk Emmens, Delegate of the Province of Groningen, who tly activated the battery. The system, which was connected to the grid in February, consists of 110 lithium iron phosphate battery racks and approximately 26 kilometres of cabling.

Nikolaus Valerius, CEO of RWE Generation, commented: “The activation of RWE’s first battery in the Netherlands here at Eemshaven represents a significant milestone in our ongoing commitment to strengthening the country’s energy infrastructure while expanding our green energy storage portfolio. We are excited about the progress made and remain steadfast in ing the energy transition in the Netherlands and beyond, ensuring that Eemshaven remains a powerhouse for energy now and in the future.”

Alongside the Eemshaven BESS, RWE is also making progress at its Moerdijk power station with the commissioning of an ultra-fast synthetic inertia battery energy storage system. With an installed capacity of 7.5 MW and a storage capacity of 11 MWh, this system is one of the first of its kind in mainland Europe, designed to maintain grid stability through innovative technology.

Both battery systems are part of RWE’s broader system integration solutions for the OranjeWind project, a Dutch offshore wind initiative developed in partnership with TotalEnergies. OranjeWind is aimed at finding new ways to integrate renewable energy into the Dutch grid, using technologies such as electrolysers, smart EV charging stations, e-boilers, and battery storage.
