Alight, a leading European solar energy developer and independent power producer, is planning a 90 MWp solar farm on a 100 hectare site in Vihti, Finland. The project also includes a 15-30 MW/60-120 MWh battery storage facility.
Located about 1.5 km from the village of Seli, the solar park is estimated to produce around 90 gigawatt hours of electricity per year, equivalent to the electricity consumption of around 18 000 households¹. When completed, it will be one of the largest solar parks in Finland.
A community event was held on 25 August to hear the views of local residents to support the design of the solar park. The project is still in the early stages of development, but if the permitting process proceeds as planned, construction could start in 2026 and the park could be operational in 2028.
"Vihti offers good conditions for the use of solar energy thanks to its good radiation levels and sufficient grid capacity. This project will contribute to Finland's renewable energy targets and strengthen the country's energy self-sufficiency. We look forward to working closely with the local community and stakeholders as the project progresses," says Alexander Rudberg, Alight's Development Director.
Alight develops and operates solar parks in Finland, Sweden and Denmark and sells the clean electricity they produce to energy-intensive companies through Power Purchase Agreements (PPAs). The model guarantees the buyer a low and predictable electricity price and ensures the financial sustainability of the solar farm. Alight is in regular discussions with companies interested in renewable energy and will intensify negotiations on the Vihti solar park as the project approaches the construction phase.
