Centrica Energy has signed an optimisation agreement with Ånge Storage Solutions AB, a project company jointly established by Delta Capacity, a Swiss-based developer of utility-scale battery storage systems, and Wood & Co., a leading European investment bank and asset manager, for a 70 MW / 160 MWh battery project in Ånge, Sweden, scheduled to be commissioned in Q2 2026.

Once operational, the Ånge project will be the largest BESS currently in operation in the Nordics, underlining the strong partnership between the companies and the project’s clear strategic significance and market impact. The project represents a major step forward for grid flexibility in Sweden, supporting the country’s rapidly growing renewable energy capacity while strengthening system stability in the SE2 bidding zone.

 

Under the agreement, Centrica Energy will act as optimiser for the project, providing 24/7 in-house trading and optimisation services. Leveraging advanced forecasting, real-time market benchmarking and AI-enhanced trading algorithms, Centrica Energy will optimise the battery across wholesale electricity markets and ancillary services, dynamically capturing value across multiple revenue streams.

 

The agreement on the Ånge project kicks off the partnership between Centrica Energy and Delta Capacity, underlining the companies’ shared ambition to accelerate flexible energy solutions across the Nordics.

Our partnership with Delta Capacity strengthens our growing footprint in the Nordics and highlights the vital role that flexibility assets play in delivering a stable, renewable-led energy system. With the 160 MWh Ånge BESS project, we’re applying our full optimisation capabilities in Sweden - helping unlock value for our partners while supporting the development of a more resilient and decarbonised power market.
