Omexom Network Powers Cross-Border Collaboration in Järvilinja 1 (Lake Line) Transmission Project in Finland
Omexom in Finland, in partnership with Omexom in France, is advancing the Järvilinja 1 (Lake Line) transmission project for Fingrid, Finland’s national grid operator.
Together, the teams are building 216 new transmission towers, installing 66km of double-circuit 400–kV and 110–kV overhead lines, and dismantling 51 km of aging infrastructure, which involves removing 223 towers. Most of the towers are guyed tubular towers and rest of the towers are lattice self-supporting ones.
From Design to Integration: Advancing Finland’s High-Voltage Grid Upgrade
So far major milestones with design, procurement, foundation work, assembly and erection and stringing are achieved. The final phase of the project is ongoing, and project is proceeding according to the plan.
As Omexom’s first 400-kV project in Finland, the project demanded specific designs, unique technical specs, and new guyed tubular tower types for both 400-kV and 110-kV lines.
Charles Cocuelle, Project Manager at Omexom in France and currently based in Finland for the duration of the project, reflected on the experience:
Diversity, Inclusion, and Environmental Commitment in Action
The Järvilinja 1 project, featuring a diverse international workforce and delivered by an integrated team, requires close coordination across different cultures and working styles. The team communicates in Spanish, English, French and Finnish, underscoring the project’s multicultural nature.
The involvement of workers from four continents introduced logistical and administrative challenges, particularly with documentation, training, and site integration, but these were well managed by Omexom in Finland.
The project has also pioneered a unique HR approach by hiring and relocating a full African team to Finland, showcasing an inclusive and forward-thinking workforce strategy.
One key highlight of the project is the strong commitment to environmental sustainability. All Omexom vehicles on the project run on renewable diesel. This initiative has been well received and appreciated by Fingrid.
Located in remote, swampy terrain near Vuolijoki, making winter construction essential, the teams have been working on frozen ground. Despite ice cold conditions, progress on the Järvilinja 1 transmission project remains steady as it moves toward completion in 2026, serving as an exemplary model of Omexom’s end-to-end EPC service delivery.
