RWE gives the green light for 220-megawatt battery storage in North Rhine-Westphalia – Batteries News | CarTailz

RWE gives the green light for 220-megawatt battery storage in North Rhine-Westphalia.

RWE continues to expand its battery storage technology business. The company has completed its investment decision for a 220 megawatt (MW) battery storage project in Germany. A total of 690 lithium-ion battery blocks are to be installed at the RWE power plant sites in Neurath and Hamm in North Rhine-Westphalia.

The total investment is around 140 million euros. Subject to the pending building permit, construction is scheduled to begin in 2023, with commissioning scheduled for 2024.

The new system is designed to respond within seconds and deliver the power you need for over an hour. As a result, the system can contribute to efficient grid stabilization with a reliable power supply. What is unique about the system is that the new battery is virtually networked with RWE’s German power plants.

This enables optimal management of which unit, individually or as a group, efficiently provides control energy and when. RWE leverages its engineering capabilities in energy storage by providing detailed project design, modelling, system integration and commissioning.

Roger MiesenCEO of the RWE Generation:

This investment decision paves the way for a forward-looking project that will set new standards in terms of size and intelligent networking.

“Our new battery storage system will optimize the utilization of our German power plant park and jointly provide control energy.”

Lars KulikMember of the Executive Board of RWE Power:

Against the background of structural change, this group-wide joint project enables traditional power plant locations with the latest storage technology and innovative networking systems to make their contribution to the energy supply of the future.

RWE plans to implement this storage project in existing power plants in order to maximize the synergy effects across the technologies. The batteries can be installed in the existing areas, using the existing grid infrastructure for feed-in and feed-out.

In Neurath, batteries with a total output of 80 MW are to be installed on an area of ​​around 7,000 m², which roughly corresponds to a soccer field. And in Hamm, batteries with a total output of 140 MW are to be installed in the Westfalen power plant on an area of ​​14,000 m². The company plans to use brand-new lithium-ion batteries that are built into cabinets and delivered as prefabricated modules.

Battery storage @ RWE

Battery storage systems are an essential part of the energy transition because they store the residual electricity from overproduction in the grid and make it available again when needed. As one of the pioneers of the energy transition, RWE develops, builds and operates battery storage systems in Europe, Australia and America.

RWE currently operates a total installed battery storage capacity of around 150 MW (160 MWh) and carries out battery storage projects of more than 800 MW (1,800 MWh) worldwide. RWE aims to build three gigawatt batteries by 2030.

This year, RWE commissioned a 60MW battery storage system in Ireland and a 40MW battery storage system in connection with a solar PV plant in Georgia, USA. In Germany, RWE is currently commissioning a 117 MW project that is virtually connected to the run-of-river power plants on the Moselle.

In its other projects, RWE uses storage systems from used electric car batteries (“second life” batteries) or liquid batteries, so-called redox flow systems. In addition, RWE offers industrial customers tailor-made, forward-looking solutions, drawing on its know-how in energy trading and innovative storage systems.


  • Storage systems are to be installed at the locations of the RWE power plants in Neurath and Hamm
  • The total investment is around 140 million euros
  • RWE is planning innovative coupling with other technologies
