Finland’s electricity grid is set to receive a significant enhancement with the construction of the 400kV Halsua and Ullava substations, following a contract signed between domestic transmission system operator Fingrid and Caverion.

This turnkey contract, encompassing earthworks, equipment delivery, installation, and commissioning, marks a step towards bolstering Finland’s electricity transmission capacity.

The contract between Fingrid and Caverion also includes comprehensive construction and engineering works for the substations, which are set for completion between 2025 and 2027.

These substations are expected to be operational by mid-2027, contributing to the country’s transition to renewable energy sources and thereby supporting its climate objectives.

Caverion Business, Industrial Projects and Infrastructure head Kari Aalto said: “At Caverion, we are involved in all stages of the energy chain – from ensuring production, to energy transmission and consumption.

“Renewable energy projects, such as the ones we have worked in close partnership with Fingrid, play a major role in our service offering. We are happy to count on Fingrid’s continued trust and we are excited to be part of building a climate-friendly and energy-self-sufficient Finland.”
