Ånge, 23 June 2026 — WOOD & Company and Delta Capacity have started the commercial operation of Ånge Storage Solutions, a 70 MW / 160 MWh (2-hour system) battery energy storage system (BESS) near Ånge, central Sweden. Completed within 15 months, it is the largest battery storage project currently in operation in the Nordics. The project provides critical grid flexibility to the SE2 bidding zone and supports Sweden's ongoing energy transition.
The project was acquired as a Ready-to-Build asset from RES in February 2025 by Ånge Storage Solutions AB, a joint venture between WOOD & Company Renewables Sub-Fund (holding a significant majority) and Delta Capacity. Delta Capacity served as co-investor and EPC manager, leading all phases from design through commissioning. Key delivery partners included Sungrow as battery system supplier, Stenger & Ibsen Construction as balance of plant contractor, Rejlers on construction management support, Green Power Monitor on energy management system and SCADA, Solvina on grid code compliance, and Ellevio as grid owner. Centrica Energy will act as optimiser for the project, providing 24/7 in-house trading and optimisation services.
"A project like this is never built by one team alone. Ånge came to life through an exceptional partnership managed by a strong team from Delta Capacity. As renewable generation accelerates across the Nordics, this is exactly how grid-scale storage needs to be delivered: at speed, at scale, and through genuine collaboration," commented Lars Björklund, Chairman of the Board of Ånge Storage Solutions AB.
"For WOOD & Company Renewables Sub-Fund, Ånge represents a high-quality asset in a strong regulatory environment, delivered by best-in-class project partners in construction, operation and electricity trading. It is a significant addition to our portfolio and a strong signal of the value battery storage brings to the Nordic energy market.", said Robert Doucha, its Investment Director.
"The Nordic energy transition is moving fast, and it needs infrastructure that can keep pace. Sweden has extraordinary renewable resources, but flexibility is the missing piece, and that is exactly what Ånge delivers. 160 MWh of grid-scale storage, brought to market in 15 months. Delta Capacity's ambition is to keep building, faster and at greater scale, because the energy transition cannot wait.”, said Patrik Hes, CEO of Delta Capacity.
The Ånge BESS will contribute to balancing Sweden’s power system as renewable penetration rises, offering rapid response capabilities and capacity for both frequency regulation and arbitrage across the volatile Nordic power market.
