Sähkönkantaverkko

Sähkönkantaverkko, also known as the Finnish national grid, is the high-voltage electricity transmission network in Finland. It is owned and operated by Fingrid Oyj, a state-owned company. The sähkönkantaverkko's primary role is to transmit electricity reliably and efficiently from power generation sites to the distribution networks, which then deliver electricity to consumers. It also plays a crucial role in maintaining the balance between electricity supply and demand across the country and ensuring the stability of the entire power system.

The network consists of high-voltage power lines, substations, and control centers. These components are essential for transporting large amounts of electricity over long distances with minimal energy loss. The sähkönkantaverkko is interconnected with the electricity grids of neighboring countries, such as Sweden and Estonia, facilitating electricity trade and enhancing the security of supply. This international connectivity allows Finland to import electricity when domestic production is insufficient and export surplus power.

Key responsibilities of Fingrid and the sähkönkantaverkko include ensuring the continuous operation of the grid, managing electricity flow, and planning for future network development to meet growing energy demands and integrate renewable energy sources. The grid's reliability is paramount, as interruptions can have significant economic and societal consequences. Therefore, continuous monitoring, maintenance, and investment in modern technology are ongoing priorities for Fingrid to maintain a secure and robust sähkönkantaverkko.
