Siirtoverkon

Siirtoverkon is a Finnish term that translates to "transfer network" or "transmission network." It most commonly refers to the physical infrastructure used for transmitting electricity over long distances. This network consists of high-voltage power lines, substations, and transformers that are essential for moving electricity from power generation plants to where it is consumed, such as cities and industrial areas.

The operation of the siirtoverkko is crucial for maintaining a stable and reliable electricity supply. It is designed to minimize energy loss during transmission, although some loss is inevitable due to the resistance of the wires. The voltage is stepped up to very high levels for long-distance transmission to reduce current and thus reduce resistive losses. Near consumption points, the voltage is then stepped down in stages to safer and more usable levels for homes and businesses.

In Finland, the national siirtoverkko is managed by Fingrid Oyj, a state-owned company. Fingrid is responsible for the planning, construction, maintenance, and operation of the high-voltage transmission grid. They also ensure the balance between electricity production and consumption in real-time, which is a complex task involving managing various sources of power and responding to fluctuations in demand. The term can also sometimes be used in a broader sense to describe other types of transmission networks, such as those for gas or telecommunications, but its primary association is with the electricity grid.
