The contracts secured in December alone represent a total capacity of 20 MW and 40 MWh and are all now in the detailed planning phase.\n\nThis press release features multimedia.

These newly signed projects reflect the trust that energy utilities are placing in us. These businesses increasingly value companies with long-standing experience, proven references and strong technical execution capabilities, and, across the entire value chain, this is where we are well positioned,” said Thomas Speidel, CEO of ADS-TEC Energy.\n\n\nThe new contracts build on a growing customer reference base in the battery energy storage market from large-scale systems operating successfully since 2016 to the recently announced project for Stadtwerke Ludwigsburg-Kornwestheim (SWLB) in Germany. SWLB selected a BESS5000 system with a capacity of five megawatt-hours (MWh) for integration with its biomass power plant to enhance grid stability while enabling participation in energy and ancillary service markets.\n\n\nIn early December, ADS-TEC Energy realized its first large-scale battery storage project in Austria at AAE Naturstrom. A BESS5000 system with a capacity of 5 MWh has been installed and commissioned on schedule. Its integration with a photovoltaic (PV) system demonstrates how locally generated solar power can be stored, flexibly marketed, and fed into the grid as required.\n\n\nAnother flagship ADS-TEC Energy large-scale battery storage project is a unique project in Germany that features a 1 GW grid connection and 2 GWh of storage capacity with a potential expansion to 4 GWh. “We are very sati...
