The acquisition marks Monsson’s first implementation of its own BESS solution in Sweden.
The Eskilstuna BESS project has obtained all necessary permits and is scheduled to begin construction in June 2025. Monsson’s CEO, Joanna Lilliequist, stated: “Monsson has been active in Sweden for over a decade, mainly through wind farm operation and maintenance services. With this acquisition, we are now positioning ourselves as a developer, service provider and investor, committed to acquiring, building and operating advanced energy storage systems across the Scandinavian market.” The project’s energy storage systems are engineered to ensure high efficiency and reliability for grid services and electricity trading.
Monsson aims to expand its presence in Sweden, targeting over 200 MWh of storage capacity in the future to support further investments and partnerships in the region. Sebastian Enache, Monsson Group’s head of mergers and acquisitions, commented: “We currently operate 72MWh of energy storage and have another 348MWh under construction. With the additional 60MWh project in Eskilstuna, we’re aiming for a European storage portfolio of over 1,000MWh, including projects in Germany, Finland, Italy and Croatia.” This acquisition strengthens Monsson’s growing portfolio of energy storage solutions across Europe.
In a separate transaction in April 2025, Monsson sold a 272-megawatt wind project in Cara?-Severin County, Romania, to Verbund Wind Power Romania, a subsidiary of the Austrian energy group Verbund. The fully developed wind project, which has secured all permits and grid connection points, is expected to produce approximately 569 gigawatt-hours annually, with construction set to start in 2026. These developments highlight Monsson’s commitment to advancing renewable energy infrastructure across multiple markets, contributing to sustainable energy production and regional economic growth.
