Scandinavia's largest battery storage project has entered commercial operation in Ånge, Sweden, with Sungrow supplying its PowerTitan 2.0 platform at 70 MW of power and 160 MWh of capacity. Developed by Delta Capacity, the installation is designed to stabilise the local grid and bring flexibility to the volatile Nordic power market through fast response times, frequency regulation and arbitrage. The unit is also built to perform reliably in the extreme conditions typical of the region in the winter months.

The Ånge facility is owned by a joint venture between the WOOD & Company Renewables Sub-Fund and Delta Capacity, which led the project from planning to completion in just 15 months. "Sweden has excellent renewable resources, but it lacks flexibility, and that is exactly what Ånge provides," said CEO Patrik Hes. RES took over the project in February 2025, while Centrica Energy markets the plant, buying and selling its power around the clock.
Sweden's storage boom
The project lands in a Swedish storage market that is expanding rapidly alongside the country's energy transition. According to SolarPower Europe, the regulatory framework allows batteries to participate in balancing markets with little friction, making them an attractive asset class. Sweden and Finland together installed more than 1 GWh of new battery capacity in 2025.
Founded in 2022 and headquartered in Switzerland, Delta Capacity currently has almost 800 MWh under construction, with a 1 GWh pipeline planned for 2026 and a long-term target of more than 6 GWh of flexible storage capacity by 2030.

Sungrow Europe operates more than 25 local subsidiaries, two research and development centres and 26 warehouse locations across the continent, serving Sweden from Stockholm with further Nordic offices in Malmö, Copenhagen and Helsinki. Recent projects in the region include Scandinavia's largest rooftop PV installation in Sweden (14 MW) and Europe's northernmost solar project in Finland (70 MW). (TF)
