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.
