Finland's national grid operator Fingrid is planning a massive new power transmission line stretching from Pyhäjärvi to Kouvola. The proposed Harju Line would potentially cross through eastern parts of Central Finland. Environmental impact assessments are currently underway for sections between new substations in Murtoperä, Pyhäjärvi and Kauppila, Kangasniemi.
The Harju Line design features two parallel 400-kilovolt and 110-kilovolt transmission lines. Construction approval decisions will come next year, with completion targeted for 2032. This infrastructure project addresses Finland's growing electricity transmission needs, particularly moving power from northern wind farm developments to southern consumption centers.
Finland faces substantial energy transmission challenges as the country accelerates its green transition. Existing power lines like the Metsä Line and Järvi Line are being reinforced alongside new construction. Fingrid aims to meet reliability requirements while maintaining uniform electricity pricing across the country.
The timing reflects Finland's rapid expansion of renewable energy capacity. Wind power generation has tripled since 2018, creating urgent transmission bottlenecks. Central Finland's strategic location between northern production areas and southern industrial centers makes it crucial for grid development.
Local municipalities along the proposed route now face important decisions about land use and community impact. Public maps allow residents to see exactly where the massive power lines might cross their regions. The project represents one of Finland's largest energy infrastructure investments this decade.
Grid reliability remains a critical concern following recent European energy market volatility. Fingrid's construction program aims to prevent price disparities between regions while supporting Finland's industrial competitiveness. The Harju Line specifically addresses capacity constraints that could otherwise limit economic growth in southern Finland.
International readers should understand that Finland's energy transition moves faster than many European counterparts. The country already generates over 50% of its electricity from renewable sources. These transmission projects enable further renewable expansion while maintaining the reliable power supply that supports Finland's technology-intensive economy.
