Centrica has commissioned two battery energy storage systems in Borlänge, southern Sweden, each delivered in partnership with global energy solutions provider Omexom. The systems, which came online in early April 2026, offer a combined power capacity of 40 MW and are expected to deliver approximately 21,900 MWh annually—sufficient to power around 1,100 homes for a year.
These installations enhance grid flexibility by storing renewable energy when demand is low and discharging it during peak periods. This capability helps balance fluctuations in electricity production and consumption, supporting the integration of variable renewable sources across Sweden’s transmission network.
Centrica Energy will oversee the optimisation and operation of these assets. The company currently manages a portfolio of more than 770 MW of contracted battery storage capacity across Europe. By adjusting battery output in real time, Centrica aims to maximise the use of available green electricity, deliver cost-effective energy storage services to grid operators, and secure a stable return on investment.
The Borlänge project is part of Centrica’s wider £4 billion investment programme to accelerate the transition to a low-carbon energy system. In addition to battery storage, this programme includes investments in nuclear power, hydrogen, and solar energy. Dave Kirwan, Managing Director of Centrica Power, said: “As we continue to scale our investment in low-carbon flexibility, battery storage will play a vital role in helping us transition to a more sustainable energy system.”
From Omexom’s perspective, the project involved several months of engineering, system integration, and commissioning activities, including grid compliance and performance testing. Thibault Fauquant, Business Unit Manager of Omexom Conversion & Storage, and Kristoffer Ekman, Business Unit Manager of Omexom Göteborg Renewable Energies, noted that energisation marks the beginning of the site’s operational phase. Over the next ten years, Omexom teams will manage ongoing maintenance and performance monitoring to ensure long-term reliability and efficiency.
