Noveria Energy GmbH and TenneT TSO GmbH signed a grid construction agreement to connect a large-scale battery energy storage system to Germany’s transmission network. The project, located in Mecklenburg-Vorpommern near Wismar, is designed to deliver 500 MW of power capacity and 1,000 MWh of energy storage. Once operational, the installation will provide frequency regulation, load shifting and fast-response ancillary services to bolster grid stability and support greater integration of renewable generation.
Under the agreement, TenneT will lead the engineering, procurement and construction of high-voltage infrastructure, including a new 380 kV substation equipped with transformers, switchgear and connection lines. Noveria Energy will supply and install the battery modules, power conversion systems and control software required for safe and efficient operation. Construction is scheduled to begin in mid-2026, with commercial operation targeted for late 2027.
Dr. Matthias Bauer, CEO of Noveria Energy, said the partnership advances the company’s goal of expanding grid-scale storage solutions that balance renewable output and strengthen network resilience. “Collaboration with TenneT enables us to deploy critical infrastructure that supports Germany’s energy transition,” he remarked.
Dr. Simone Sturn, TenneT’s board member for asset management and engineering, highlighted the growing need for large-scale storage as wind and solar capacities rise. “Grid-scale batteries are essential for maintaining reliable supply and optimizing transmission assets during the phase-out of conventional power plants,” she noted.
This agreement builds on a memorandum of understanding signed in 2024, under which both companies committed to jointly develop energy storage projects. Their continued cooperation underscores a shared vision to expand clean-energy infrastructure and ensure security of supply in Europe’s evolving power landscape.
