UK-based investment firm Foresight Group has commenced operations at the 277-megawatt Kolvallen wind farm in central Sweden, marking one of the largest onshore wind projects in the country to date.
Located in the Harjedalen municipality, the project features 42 Siemens Gamesa turbines, each with a capacity of 6.6 MW. Construction began in June 2022 and was completed in May 2025. A formal inauguration ceremony was held this month.
The wind farm is expected to generate 957 gigawatt hours of electricity annually, equivalent to the consumption of approximately 95,000 Swedish households, according to Foresight.
“This landmark project not only adds significant renewable capacity to Sweden’s grid, but also demonstrates our commitment to sustainable construction practices, community engagement, and supporting Europe’s transition to clean energy,” said Richard Thompson, partner and co-lead of Foresight’s Energy Infrastructure Partners (FEIP) fund.
The construction process incorporated several sustainability measures, including the use of recycled reinforced steel, locally sourced gravel, and onsite concrete batching. These practices helped reduce carbon emissions during construction by approximately 54%, the company said.
Foresight expects the wind farm to become climate neutral within four months of starting operations.
A community benefit fund will be established to support local initiatives, funded by a share of the wind farm’s annual revenues. Additionally, six local technicians have been hired to oversee operations and maintenance, contributing to the regional economy.
Foresight developed the project in partnership with Swedish renewables firm Arise, which will continue to provide project management services throughout the operational phase.
“This world-class renewable energy asset will, through its scale and efficiency, deliver real benefits for the environment and community, drive industrial growth, and strengthen the resilience of our energy system in uncertain times,” said Arise CEO Per-Erik Eriksson.
