A 70MW/160MWh battery energy storage system in Ånge, Sweden, has entered commercial operation after a 15-month procurement and construction programme.
Sungrow supplied its PowerTitan 2 utility-scale LFP battery system for the project, which developer Delta Capacity described as the largest commissioned BESS in the Nordic region.
Located in Sweden’s SE2 electricity bidding zone, the facility will participate in frequency regulation and energy arbitrage while providing flexibility to the country’s power system.
Samer Nameer, country manager Sweden at Sungrow, said: “Ånge is a great example of how large-scale energy storage is built in practice. Fast, at the right scale and with the right partners like Delta Capacity. Our role is to be a long-term partner and contribute to expanding renewable energy capacity in Sweden.”
The BESS is owned by a joint venture between WOOD & Company Renewables Sub-Fund and Delta Capacity. The latter led the project from design through to completion, with the period from the start of procurement to commercial operation taking 15 months.
Delta Capacity acquired the project from renewable energy company RES in February 2025.
Sweden has great renewable resources but lacks flexibility
Patrik Hes, CEO of Delta Capacity, said: “The Nordic energy transition is moving fast and requires infrastructure that keeps the same pace. Sweden has great renewable resources, but flexibility is missing and that is exactly what Ånge provides. 160 MWh of storage, delivered in 15 months. Delta Capacity’s goal is to keep building, faster and at greater scale. The energy transition cannot wait.”
Other companies involved in the development included Stenger & Ibsen Construction, Rejlers, Green Power Monitor, Solvina and Swedish distribution network operator Ellevio. Centrica Energy will manage the round-the-clock buying and selling of electricity for the facility.
Sweden’s battery storage market is growing as storage assets gain access to the country’s balancing markets. Sungrow cited figures from SolarPower Europe showing Sweden and Finland installed more than 1GWh of new battery capacity between them during 2025.
Founded in 2022 and based in Switzerland, Delta Capacity develops, acquires, owns and operates utility-scale battery storage projects across Europe. The company said it currently has almost 800MWh under construction and is targeting a portfolio of more than 6GWh of operational flexible assets by 2030.
