Battery storage systems are an essential component of the energy transition because they store energy during an overproduction of electricity in the grid and then release it again when it is needed. RWE is currently operating battery storage projects with a capacity of around 300 MW (380 MWh), as well as realising worldwide battery storage projects with a total output of more than 900 MW (2,300 MWh). The large-scale 220 MW project in North Rhine-Westphalia, which was officially presented in November 2022, is to break new ground for the use of storage technologies at RWE’s power plant fleet in Germany. A total of 690 blocks of lithium-ion batteries will be installed at sites in Neurath and Hamm. By opting for the sites of its existing power plants, RWE is able to take advantage of the synergy of combined technologies. The prefabricated batteries will be installed in cabinet form, utilising surfaces that are already available, and will be connected to existing grid infrastructure.

New energy storage system contributes to the power supply of the future
Intelligent networks to optimise utilisation of the power plant fleet
The planned system reacts within seconds and can provide its power over the duration of one hour. Thereby the system contributes to the stabilisation of the grid and to a reliable power supply. The new battery storage is virtually networked with RWE's German power plants. This allows an optimised control of when which power plant provides balancing energy.
RWE benefits from its many years of expertise in the field of energy storage - project planning, modeling, system integration and commissioning of the project are all handled by RWE autonomously. The group-wide joint project is a successful example of structural change. With this project, traditional power plant locations can contribute to the German and European energy supply with an innovative network.
