Ingrid, a leading Nordic player in system-critical energy infrastructure, is developing two new large-scale battery systems in Vaggeryd, Småland, and Horsaryd, Blekinge. The facilities will have a total capacity of 600 MWh, doubling Ingrid’s Nordic battery storage portfolio. The projects represent the next generation of battery storage, featuring new capabilities and designed to create a stronger and more resilient power system.
Once operational, the Vaggeryd battery system will be Sweden’s largest at 100 MW/400 MWh - and the country’s first large-scale four-hour system. The Horsaryd system will provide 100 MW/200 MWh and strengthen the power system in SE4, where the need for greater flexibility is high. Together, the two systems deliver 600 MWh, increasing Ingrid’s current Nordic battery portfolio from 650 MWh to 1.2 GWh.
“The projects in Vaggeryd and Horsaryd clearly demonstrate Ingrid’s ambition, and we are proud of them. To be a significant player that strengthens our energy supply - not just at the margins - you need a long-term perspective and a deep understanding of the entire energy system. We built Ingrid to be a major infrastructure player from day one, and it’s rewarding to see the results. Being the first in Sweden to establish a large-scale four-hour system is, of course, exciting, but we’re already focused on the next milestone,” said Axel Holmberg, CEO of Ingrid.
After several years of work, the projects in Vaggeryd and Horsaryd have reached key milestones this year. Both projects have obtained building permits that have gained legal force, and the permit for Vaggeryd is now being reapplied for with updated technical specifications to increase capacity from 200 to 400 MWh. Construction of the projects is expected to begin as early as 2026, with full operation planned for 2028.
Ingrid develops, operates, and optimises its battery facilities, making the company the largest player in the Nordics focused on battery system optimisation.
Ingrid’s project pipeline totals 7.4 GW. In addition to ongoing projects in Sweden and Finland, Ingrid is also developing battery storage in Germany and France as the first step in its European expansion.
