BattMan Energy ensures stable and clean power for Denmark with battery energy storage

Large investments and the massive integration of renewable energy sources are a key part of the solution to a fast, flexible, and safe energy transition in Denmark and the rest of the world. Renewable energy sources, including solar and wind, contribute more to the Danish power supply every day. Often, the availability of these renewables varies based on the weather. Therefore, to integrate these resources into the grid, new technologies like battery energy storage are added to ensure availability and reliability. Denmark is recognized as a leader in the energy transition by the International Energy Agency (IEA) and has the highest share of wind electricity in their energy mix of the IEA member countries, which further underlines the importance of stabilizing technologies such as battery energy storage.

The Danish cleantech company BattMan Energy, which specializes in implementing battery storage systems (BESS), has chosen Hitachi Energy as the battery energy storage system supplier for its three newest plants in Denmark. Some of the country’s largest BESS facilities, the plants will have a collective effect of 36 megawatts (MW)/72 megawatt-hours (MWh) and can supply around 6,000 Danish households with power for one day. The first two plants are expected to be ready in June 2025.

The agreement is an important milestone for both parties and supports Hitachi Energy's Purpose of advancing a sustainable energy future for all. BattMan Energy aims to facilitate and execute investments of more than €100 million in batteries to stabilize the electricity grid by the end of 2024 and strengthen Denmark's position as a global leader in sustainable energy. 

Daniel Kappelgaard, Co-founder and CEO at BattMan Energy says, "By implementing battery storage systems like these, we can ensure a stable and green power supply to Danish homes while contributing to the rapid transition toward renewable energy,” he says. “We are pleased to have chosen Hitachi Energy as a partner for these projects and look forward to working with them to achieve significant and tangible results within our vision of supporting a strong grid and a carbon neutral Denmark. Our goal is to be a pioneer in sustainable energy solutions and make a real difference in the renewable transition, and with these three projects we are well on our way."

He continues, “Together with Hitachi Energy, we have also begun the co-development of an approximately 500-MW/1.5-gigawatt-hour (GWh) BESS in Denmark, which will be a record-breaking project for us.”

Claus Madsen, Country Managing Director of Hitachi Energy in Denmark, sees great potential in the battery plants, and says, “Battery energy storage systems are absolutely central to the clean transition, the stabilization of the grid and are a large part of the future energy system. I am delighted to work with innovative and driven customers like BattMan Energy to support the widespread adoption of such advanced technologies at the edge of the grid.”

John Finney, Head of Grid Edge Solutions, adds, “Denmark is a clear leader in the energy transition, with a significant amount of generation coming from renewable sources, and storage added at the grid edge closer to where the power is consumed. As the traditional boundaries of the grid change, more energy management and optimization solutions are also needed. BattMan Energy is tapping into a unique and smart opportunity in the market, and we expect to see more of this type of model in Denmark and throughout Europe.”  

Hitachi Energy acquired eks Energy, a leading supplier of power electronics and energy management solutions for storage and renewables integration, based in Seville, Spain. The complementary advantages of Hitachi Energy’s e-mesh™ BESS system integration capabilities, combined with acquired power conversion solutions (PCS) from eks Energy, are also evident in this BattMan Energy project.
