Delta Capacity has announced commercial operation of a 70MW/160MWh Sungrow PowerTitan 2 BESS in Sweden — which the partners say marks the launch of the largest individual such project in the Nordics to date.

Swiss-based Delta said on July 20 the Ånge BESS will contribute to balancing Sweden’s power system while offering rapid response capabilities and capacity for both frequency regulation and arbitrage across the volatile Nordic power market.

Ånge is owned by a joint venture between Delta and sustainable investment fund WOOD & Company Renewables Sub-Fund — which has led the project from design to completion.

The project was acquired from Renewable Energy Systems in February 2025 and has taken 15 months from procurement through to commercial operation. Financial details were not disclosed.

Delta said 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 industry data.

Sweden and Finland together installed more than 1GWh of new battery capacity last year, according to Solar Power Europe’s EU Battery Storage Market Review 2025.

Sungrow country manager for Sweden, Samer Nameer, said: “Ånge is a great example of how large-scale energy storage is built in practice. Our role is to be a long-term partner and contribute to expanding renewable energy capacity in Sweden.”

Delta CEO Patrik Hes 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.”

As of December 2025, Sungrow has installed over 1,000GW of power electronic converters worldwide.  

Delta already has nearly 800MWh under construction and targets the build-out, commissioning, and operation of more than 6GWh of flexible assets by 2030.
