The Bålforsen plant will produce 506GWh annually upon completion.
Valued at approximately SEK 200 million ($20 million), the contract supports Uniper’s strategy to increase renewable energy production. Preparatory work at the Bålforsen facility began in late 2024, and NCC will now undertake the installation and upgrades. The project is set to be completed by late 2027, with the contract value recorded in NCC’s Infrastructure business segment in the third quarter of 2025.
Jonny Arrehag, Uniper’s Umeälven expansion project program manager, stated: “The Umeälven expansion is an important project as it is fully aligned with our strategy to expand our supply of flexible, green energy.” The initiative aims to enhance the plant’s contribution to sustainable energy in the region.
Upon completion, the Bålforsen plant is expected to generate 506 gigawatt-hours annually, sufficient to power nearly 25,000 households. The upgrades will also improve the delivery of system services, ensuring more reliable electricity supply and better river flow management.
André Persson, NCC Infrastructure area manager, said: “Thanks to NCC’s extensive experience of advanced infrastructure projects and our strong local connection, we can support Uniper in achieving its goals for the expansion of the Bålforsen hydropower plant. This work requires a high level of specialist expertise, and we will maintain a strict focus on safety during the project.”
The Bålforsen expansion underscores Uniper’s commitment to renewable energy and aligns with Sweden’s broader sustainability goals. NCC’s expertise in complex infrastructure projects positions it to deliver the specialized work required, reinforcing its role in advancing clean energy initiatives.
In addition to this project, NCC recently secured a contract to supply 200,000 tons of asphalt for the E6 Berkåk-Vindåsliene road development in Norway’s Trøndelag region, highlighting its growing portfolio in sustainable infrastructure. The Bålforsen project marks a significant step in enhancing Sweden’s renewable energy capacity, contributing to a more sustainable energy future for the region.
