RWE Approves Major 400 MW Battery Project in the Netherlands

German energy major RWE has taken the final investment decision to construct a massive 400 MW/1100 MWh battery energy storage system (BESS) at the Moerdijk power station site in Noord-Brabant, Netherlands. The ambitious project is slated for commissioning in the second quarter of 2028 and represents a significant step in bolstering the Dutch power grid.

Alleviating Regional Grid Congestion

The Moerdijk BESS will connect directly to the national grid via an existing substation. Through strategic capacity steering agreements with the transmission system operator TenneT, the battery will be dispatched specifically to alleviate regional bottlenecks in Noord-Brabant. This targeted deployment will create much-needed grid space for waiting parties looking to connect new renewable assets.

TenneT and regional distribution system operator Enexis will review the impact on congestion management in December 2026 to ensure optimal grid utilization.

The physical infrastructure will consist of 208 lithium-ion battery containers, capable of delivering full output for nearly three hours. Notably, the Moerdijk site already hosts a 7.5 MW/11 MWh synthetic inertia battery, demonstrating the location's growing importance in grid stability.

Supporting Offshore Wind Integration

Beyond local congestion relief, the new Moerdijk project plays a pivotal role in supporting RWE’s 795 MW OranjeWind offshore wind project. By providing robust onshore flexibility, the battery system will effectively balance renewable power fluctuations, ensuring a smoother integration of offshore wind into the broader European energy market.

In the Netherlands, RWE currently operates two BESS facilities, including the existing Moerdijk battery and a 35 MW/41 MWh system at Eemshaven. Globally, the company operates approximately 1.7 GW of BESS capacity, with an additional 3 GW currently under construction.
