Ads-Tec Energy Partners with Stadtwerke Muhlacker for 10 MW Battery Storage System
Ads-Tec Energy announced that it is partnering with the public utility Stadtwerke Muhlacker for the installation of a large-scale battery storage system at its substation in Muhlacker providing 10 MW of power and a storage capacity of 20 MWh. Ads-Tec Energy is managing the planning, implementation and integration of the system, which is part of a long-term strategy to enhance the area's energy infrastructure. "This project in Muhlacker clearly illustrates the many requirements battery storage systems have to meet today," said Michael Rudloff, CEO of Ads-Tec Energy. "They must stabilize grids, be safe and reliable to operate, and at the same time be economically viable. Flexibility is increasingly important given rising electricity demand driven by electric mobility, heat pumps, and IT and digital infrastructures."
