Fingrid

Fingrid Oyj is Finland's national transmission system operator (TSO) responsible for the operation, maintenance, and development of the country’s high-voltage electricity transmission network. It ensures the secure and reliable transmission of electricity across Finland and coordinates cross-border power flows with neighboring Nordic and Baltic systems. The core of the grid is the high-voltage network, primarily at 400 kilovolts, supported by regional 110 and 220 kilovolt lines that enable transmission and distribution.

The company was established in 1997 as part of Finland’s liberalization of the electricity market, taking over the operation of the high-voltage grid from regional utilities and state authorities. Since then, Fingrid has been responsible for real-time system operation, electricity balancing, and the planning and construction of transmission infrastructure to meet changing demand and generation patterns.

Fingrid participates in Nordic and European grid planning and market arrangements and works to ensure transparent capacity allocation across borders. It cooperates with other transmission system operators and market operators to integrate renewable energy sources, improve grid flexibility, and support secure cross-border electricity trade. Fingrid also engages in planning long-term grid development to accommodate increasing demand, new generation capacity, and the integration of wind and other renewables.

Governance and regulation: Fingrid operates under Finnish energy legislation and is regulated by the Finnish energy regulator. Its activities are guided by national energy policy, with a focus on reliability, efficiency, and the ongoing modernization of the transmission system to sustain Finland’s electricity supply.
