Siirtojärjestelmänhaltija

Siirtojärjestelmänhaltija is a Finnish term that translates to "transmission system operator" in English. This entity is responsible for the operation, maintenance, and development of the electricity transmission grid within a specific geographical area. The primary role of a siirtojärjestelmänhaltija is to ensure the reliable and secure supply of electricity to consumers by managing the high-voltage network that carries power from generation sites to distribution networks.

Key responsibilities of a siirtojärjestelmänhaltija include maintaining the physical infrastructure of the transmission lines and substations, balancing electricity supply and demand in real-time, and ensuring grid stability. They also play a crucial role in planning and implementing upgrades and expansions to the transmission network to meet growing energy needs and integrate new energy sources, such as renewables.

In Finland, the electricity market is regulated, and the siirtojärjestelmänhaltija typically operates as a natural monopoly due to the high costs and complexity of building and maintaining a competing transmission network. Regulations often aim to ensure fair access to the grid for all electricity producers and suppliers, promoting competition in the generation and retail markets. The transparency and efficiency of the siirtojärjestelmänhaltija's operations are therefore subject to regulatory oversight.
