- RWE is constructing a 400 MW battery storage system in Lingen, scheduled for operation in 2028.
- The facility will have a storage capacity of at least 800 MWh, delivering max output for 2 hours.
- The site previously produced acrylic fibers until 2021.
- Construction begins on 2 February after obtaining necessary permits.
Project Overview
RWE is developing a 400-megawatt battery storage system in Lingen, Lower Saxony, on a site previously used for acrylic fiber production until 2021. The facility is set to become the largest battery storage in the region, with operations expected to commence in 2028.
Technical Specifications
The battery storage system will deliver its maximum output for at least two hours, equating to a storage capacity of at least 800 megawatt hours. It will consist of over 200 lithium-ion battery units, more than 100 inverters, over 50 medium-voltage transformers, two high-voltage transformers, and two switch panels. The facility will connect to the electricity grid via the nearby Hilgenberg substation.
Grid Stability and Energy Transition
The battery storage will play a crucial role in stabilizing the power grid by providing balancing energy and new grid services like instantaneous reserve. It will absorb or feed in power within milliseconds, depending on demand, thus supporting the integration of renewable energy sources.
Construction Timeline
Construction is set to begin on 2 February, following the acquisition of all necessary permits. The project involves preparing an 8.5-hectare site in the southern part of the industrial area for the new battery park.
