As part of the merger of RWEG and Audi AG, the construction of a 2nd Life 4,6 MWh battery storage facility with used car batteries was to be realized at the Herdecke site. The relevance of this project is illustrated by the rapidly growing market for stationary battery storage, since this technology is not only climate-friendly, but also sustainable.

As project lead during the execution phase, RWETI was commissioned with the completion of the technical aspects, the procurement process, project controlling, construction management and commissioning. In addition, our expert knowledge in the field of document and quality management ensured a successful project execution.
