RWE approves 1.1 GWh Dutch battery for grid congestion relief

The project will use 208 lithium-ion battery containers and connect through the site's existing high-voltage substation. Commissioning is planned for the second quarter of 2028, with enough output to cover the evening peak demand of about 500,000 households for almost three hours. Capacity-steering agreements will make congestion relief an explicit operating function, while the battery will also support the 795 MW OranjeWind offshore wind project's system-integration strategy.
