- RWE AG completes the construction of a battery system with a total capacity of 117 MW/128 MWh at the sites of two of its power plants in Germany
- Total investment in the project is EUR 50 million
RWE AG, the popular German power group, has now finished the construction of a battery system with a total capacity of 117 MW/128 MWh at the sites of two of its power plants in Germany to help stabilising the power grid.
The system has 420 blocks of lithium-ion batteries that are installed at the company’s sites in Lingen, Lower Saxony, and Werne, North Rhine-Westphalia. The batteries in Lingen have a capacity of 49 MWh and those in Werne — 79 MWh.
According to RWE, the total investment in the project is EUR 50 million.
Plans are that the batteries at both sites will be virtually connected to RWE’s run-of-river hydropower plants located along the Moselle River, raising the total capacity of power available grid stabilisation in the system by up to 15%. The battery storage system is now being tested with commercial operation planned to begin in the next few days.
The project was completed shortly after RWE took an investment decision for a new virtually networked 220 MW/235 MWh battery storage system in Neurath and Hamm, North Rhine-Westphalia. In December, the company also powered up a 14.4-MWp solar plant with integrated battery storage of 9.6 MWh at the site of the Inden opencast lignite mine and two similar sites are currently under construction at the Garzweiler mine.
Overall, the Essen-based power major seeks to install 3 GW of storage capacity globally by 2030.
