Sungrow Powers the Nordics' Largest Commissioned BESS Project in Sweden with PowerTitan 2

STOCKHOLM, July 27, 2026 /PRNewswire/ -- The largest battery energy storage system (BESS) project in the Nordics in Ånge, Sweden has now been taken into commercial operation. Sungrow, a global leader in battery storage and PV inverters, delivered its utility BESS PowerTitan 2.0 for the 70 MW / 160 MWh battery system developed by Delta Capacity. Designed to deliver high reliability and efficiency, the system is built to operate under challenging Nordic weather conditions and extreme temperature variations.

The Ånge BESS will contribute to balancing Sweden's power system, offering rapid response capabilities and capacity for both frequency regulation and arbitrage across the volatile Nordic power market. Sweden's battery storage market is expanding rapidly as the country's energy transition accelerates. The regulatory framework has enabled battery storage to participate in balancing markets, turning it into a revenue-generating asset, according to a report from SolarPower Europe. Sweden and Finland together installed more than 1 GWh of new battery capacity in 2025^[1].

"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," says Samer Nameer, Country Manager Sweden at Sungrow.

Fast deployment for the Nordic energy transition

The Ånge project is owned by a joint venture between WOOD & Company Renewables Sub-Fund and Delta Capacity, which has led the project from design to completion. From procurement start to commercial operation took 15 months. The facility is located in bidding zone SE2 and contributes to balancing the Swedish power system.

Patrik Hes, CEO of Delta Capacity: "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 a greater scale. The energy transition cannot wait."

The project was acquired from RES in February 2025. Other suppliers in the project are Stenger & Ibsen Construction, Rejlers, Green Power Monitor, Solvina and Ellevio. Centrica Energy manages the buying and selling of electricity for the facility around the clock.

Local presence with a global footprint

Sungrow Europe currently has 25 local offices, two research and development centres and 26 warehouses across Europe. The Swedish team with dedicated experts for Services, and energy solutions is based in Stockholm, with other Scandinavian offices in Malmö, Copenhagen and Helsinki. Among its most recent projects in the Nordic region are the Nordic region's largest solar roof in Sweden^[2] (14 MW) and the northernmost solar project in Finland^[3] (70 MW)."
