Korkeajänniteverkosto

Korkeajänniteverkosto refers to the high-voltage electricity transmission network in Finland. This network is essential for transporting electricity efficiently from power generation sources, such as power plants, to areas where it is consumed. The network operates at very high voltages, typically ranging from tens of thousands of volts to hundreds of thousands of volts, which minimizes energy loss during long-distance transmission.

The Finnish high-voltage grid is managed and operated by Fingrid Oyj, a state-owned company. Fingrid is responsible for maintaining the reliability and security of the electricity supply across the country. The network comprises transmission lines, substations, and other associated infrastructure. These transmission lines are often characterized by tall pylons carrying multiple conductors. Substations play a crucial role in stepping down the voltage to lower levels suitable for distribution to industrial users, commercial centers, and eventually residential areas through lower voltage distribution networks.

The development and maintenance of the korkeajänniteverkosto are vital for Finland's energy security and economic activity. Investments are continuously made to upgrade and expand the network, ensuring its capacity to meet future energy demands and to integrate renewable energy sources, such as wind and solar power, which are often located far from consumption centers. The grid also plays a role in international electricity connections, allowing for trade of electricity with neighboring countries.
