- Sungrow has commissioned a 70MW/160MWh battery energy storage system in Sweden, the largest operational BESS in the Nordic region.
- The project will strengthen grid stability, support renewable energy integration and provide balancing services across the Nordic electricity market.
Sungrow has announced the commercial operation of a 70MW/160MWh battery energy storage system (BESS) in Ånge, Sweden, making it the largest operating battery energy storage project in the Nordic region.
Delta Capacity developed the project using Sungrow’s PowerTitan 2.0 utility-scale battery energy storage solution.
The battery system is designed to operate under the Nordic region’s harsh weather conditions and significant temperature variations. It will strengthen Sweden’s electricity grid by providing rapid-response balancing services, including frequency regulation and energy arbitrage across the Nordic power market.
A joint venture between WOOD & Company Renewables Sub-Fund and Delta Capacity owns the facility, while Delta Capacity managed the project from design through construction and commissioning.
The companies completed the project and achieved commercial operation within 15 months of procurement. Located in Sweden’s SE2 bidding zone, the facility will improve grid stability and support greater integration of renewable energy into the national electricity system.
Samer Nameer, Country Manager for Sweden at Sungrow, said the project demonstrates how strong industry collaboration can accelerate the deployment of utility-scale battery storage while supporting Sweden’s expanding renewable energy capacity.
Patrik Hes, Chief Executive Officer of Delta Capacity, said the project addresses Sweden’s growing need for grid flexibility as the country accelerates its energy transition. He added that delivering the 160MWh storage facility within 15 months highlights the importance of rapid deployment in supporting renewable energy growth.
The project changed ownership in February 2025 when the joint venture acquired it from RES. Several companies contributed to the development, including Stenger & Ibsen Construction, Rejlers, Green Power Monitor, Solvina and Ellevio. In addition, Centrica Energy will manage electricity trading and optimise the facility’s market participation.
According to Sungrow, Sweden’s battery energy storage market continues to expand as regulatory reforms allow storage systems to participate in balancing markets and unlock new revenue opportunities.
The company also noted that Sweden and Finland installed more than 1GWh of new battery storage capacity in 2025, reflecting growing demand for grid flexibility across the Nordic region.
Sungrow added that it continues to expand its European operations through local offices, research and development centres, warehouses and a growing portfolio of renewable energy projects across the Nordic market.
