Monsson announces the launch of Eskilstuna Power Reserve, its first investment in a battery energy storage facility in Sweden. The project includes a battery energy storage system (BESS) with a capacity of 60 MWh and a power rating of 30 MW, designed for a two-hour discharge duration. Commissioning activities began in September 2026, with commercial operation scheduled for November 2026.

“Eskilstuna Power Reserve represents an important step in Monsson’s expansion into the Nordic market. Through this 30 MW / 60 MWh project, we are bringing our energy storage technology and expertise to Sweden, with the aim of contributing to grid flexibility and stability. Commissioning activities are finished, and commercial operation is scheduled for November 2026. Our team in Sweden, together with our colleagues in Romania, is ready to provide these flexibility services both locally and across Europe,” said Sebastian Enache, Head of Strategy & M&A at Monsson.

“By developing Eskilstuna Power Reserve, Monsson is expanding its portfolio of storage solutions designed to support energy systems with a growing share of renewable generation in Europe. The project provides a foundation for the company’s continued development in the Nordic region, where flexibility and efficient energy management are important components of energy infrastructure,” said Joanna Lillequist, CEO of Monsson Energy AB.
