Ingrid Capacity initiates the design phase for the Nordics’ largest battery energy storage system in Horsaryd, with a capacity of 100MW/200MWh

Ingrid Capacity is initiating the design phase of the Nordics' largest energy storage project, equivalent to 100MW/200MWh. The energy storage facility will connect to E.ON’s regional grid in Horsaryd, located in Karlshamn Municipality, with the aim of stabilizing the power grid and increasing the utilization of the existing system. This will facilitate electrification and contribute to the green transition. The project is set to begin construction in 2026 and be commissioned in 2027. 

The Role of Energy Storage in the Transition 

Flexibility solutions through large-scale energy storage store electricity during production surpluses and then feed it back into the system during shortages. Our energy storage facility will thus increase the utilization of the existing grid by releasing capacity when electricity consumption is high, without incurring costs for electricity consumers in Blekinge. As intermittent energy sources such as solar and wind increase in the system, energy storage becomes essential for achieving the acceleration of electrification and the green transition in a stable, secure, and cost-effective way. With lead times of 1–3 years, battery energy storage also demonstrates that the green transition is possible here and now, which is essential to maintaining attractiveness and competitiveness as an industrial nation. 

Connecting the Energy Storage Project to E.ON's Regional Grid 

Ingrid Capacity and E.ON initiated the project in 2022 following the opportunity to connect a battery energy storage system to E.ON's regional grid. We are now together entering a design phase with the aim of starting construction in 2026 and commissioning in 2027. This system, with a capacity of 100MW/200MWh, will be both the largest battery energy storage project built in the Nordics and the first two-hour system developed by Ingrid Capacity. 

"The initaitve in Karlshamn reinforces Ingrid Capacity’s ambition to become Europe’s leading player in flexibility solutions. We are building the tech and energy company of the future by adding flexibility on large scale in a smart, sustainable, and cost-effective way to optimize the power grid. This helps reduce bottlenecks, increases grid utilization, and enables a faster and more affordable transition for industry and our economy as a whole. Households will also benefit from our energy storage facilities as we help to mitigate rising fixed grid costs. We are therefore very proud of this initiative,” says Axel Holmberg, CEO at Ingrid Capacity 

The Benefits of the Energy Storage Project 

The energy storage initiative strengthens electricity supply in the SE4 area in southern Sweden. It will benefit the residents of Karlshamn and the region by helping to stabilize electricity prices and lower grid fees in the long term. In this way, the initiative will make Blekinge more attractive for business establishments. 

"We are very pleased that Ingrid Capacity continues to invest in Karlshamn municipality. Karlshamn is a central hub for the development and expansion of new energy sources in harmony with the green transition. This investment clearly enhances Karlshamn’s attractiveness and growth potential,” says Magnus Gärdebring, Mayor of Karlshamn Municiality.  

The energy storage facility in Karlshamn is the third project developed by Ingrid Capacity in the county of Blekinge, following a 16MW/16MWh storage facility in Karlskrona municipality and a 3MW/3MWh storage facility in Karlshamn, which we established together with Karlshamn Energi in 2022. 

The Karlshamn energy storage project will be a system with a capacity of 100MW. Karlshamn's oil-fired power plant, at maximum output, has a capacity of 662MW. This means that the energy storage system could potentially replace nearly one-sixth of the oil combustion at maximum capacity with fossil-free energy. 

The expansion of the Karlshamn energy storage system is part of Ingrid Capacity's ambitious growth plan to become the leading independent flexibility provider in Europe, with 8GW under management by 2030. By 2025, Ingrid Capacity expects to have nearly 30 projects operational across Sweden.
