Sungrow has announced the commercial operation of a 70 MW/160 MWh battery energy storage system (BESS) in Ånge, Sweden, marking the largest battery energy storage project currently in operation in the Nordic region. The project was developed by Delta Capacity and features Sungrow’s PowerTitan 2.0 utility-scale battery energy storage solution.

Designed to operate under the Nordic region’s harsh weather conditions and significant temperature variations, the battery system is expected to strengthen Sweden’s electricity grid by providing rapid-response balancing services, including frequency regulation and energy arbitrage across the Nordic power market.

The Ånge BESS is owned by a joint venture between WOOD & Company Renewables Sub-Fund and Delta Capacity, which managed the project from design through construction and commissioning. According to the companies, the project reached commercial operation within 15 months from the start of procurement and is located in Sweden’s SE2 bidding zone, where it will support grid stability and renewable energy integration.

Samer Nameer, Country Manager for Sweden at Sungrow, said the project demonstrates how utility-scale battery storage can be deployed rapidly through strong industry collaboration while supporting Sweden’s growing renewable energy capacity.

Patrik Hes, CEO of Delta Capacity, said the project addresses the increasing need for grid flexibility as Sweden accelerates its energy transition. He noted that the 160 MWh storage facility was delivered within 15 months, highlighting the importance of fast deployment to support renewable energy expansion.

The project was acquired from RES in February 2025. Other companies involved in the project include Stenger & Ibsen Construction, Rejlers, Green Power Monitor, Solvina, and Ellevio, while Centrica Energy has been appointed to manage electricity trading and optimization for the facility.

According to Sungrow, Sweden’s battery energy storage market continues to expand as regulatory reforms enable storage systems to participate in balancing markets and generate additional revenue. The company noted that Sweden and Finland collectively installed more than 1 GWh of new battery storage capacity in 2025, reflecting growing demand for grid flexibility across the Nordic region.

Sungrow added that it continues to strengthen its presence across Europe through its network of local offices, research and development centres, and warehouses, while expanding its renewable energy portfolio across the Nordic market.
