Renewal of 110 kV Transmission Line in Finnish Lapland

Totalentreprise for linjefornyelse

Omexom has been commissioned by Kittilän Alueverkko Oy to execute a turnkey project for the renewal of approximately 16 kilometers of the 110 kV overhead transmission line between Kittilä and Putkijänkä in Finnish Lapland. Omexom’s involvement began early in the project, overseeing the detailed engineering and design phases to ensure a smooth transition from planning to construction.

Bygging med robuste stålmaster

The project involves replacing aging infrastructure that has reached the end of its operational life to secure long-term grid reliability. The new transmission line will be built primarily within the existing right-of-way to minimize additional land use and protect the region’s sensitive natural environment. To ensure durability in northern Finland’s challenging conditions, the line will use steel tubular poles supported by guy wires throughout the route. Construction is set to begin with foundation work in November and is expected to be completed by the end of summer 2027.

Økt pålitelighet og kapasitet

Upon completion, the upgraded transmission line will significantly improve the reliability and efficiency of electricity transmission in the area by reducing transmission losses and ensuring uninterrupted power delivery. This renewal comes at a critical time, as Finland’s electricity consumption is projected to quintuple by 2040 due to increased demand from data centers and hydrogen production. Projects like this also contribute to Finland’s larger grid reinforcement efforts, with Fingrid planning to invest EUR 5.2 billion through 2035.

Bærekraftig oppgradering i Lappland

Beyond reliability improvements, the project highlights a sustainable approach to modernizing energy infrastructure in environmentally sensitive locations by reusing existing corridors and implementing robust, future-proof technology. Lapland is poised to become a key player in Finland’s energy transition, potentially generating up to 45 TWh of wind power annually by 2050, further underscoring the importance of resilient and efficient grid infrastructure.
