Germany – RWE has made a final investment decision for a 220 MW battery storage project in Germany.
In total, 690 lithium-ion battery blocks will be put at the locations of RWE’s power plants in North Rhine-Neurath Westphalia’s and Hamm. The overall investment is perhaps about 140 million euros. Construction is expected to begin in 2023, with commissioning planned for 2024, subject to the receipt of the required building permit.
A total of 80 MW worth of batteries will be put at Neurath over a surface area of about 7,000 m2, or roughly one football field. Additionally, Hamm’s Westfalen power station will install batteries with a combined 140 MW capacity over a 14,000 m2 area.
Unique features
The new technology is made to respond in only a few seconds while providing the necessary output for more than an hour. The system’s unique feature is the new battery’s virtual networking with RWE’s German power facilities. This permits efficient control in terms of which unit, either individually or collectively, effectively delivers balancing energy.
To optimize the benefits of technological synergy, RWE intends to deploy this storage scheme at existing power facilities. The grid infrastructure can be used to feed energy into and out of the batteries in the locations where they are currently deployed.
