siirtojärjestelmänhaltijas

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 high-voltage electricity transmission grid within a specific geographical area. The primary role of a siirtojärjestelmänhaltija is to ensure the secure and reliable transfer of electricity from power generation plants to distribution networks, and ultimately to end consumers.

Key responsibilities of a siirtojärjestelmänhaltija include managing the flow of electricity in real-time, maintaining the physical infrastructure such as power lines and substations, and planning for future grid expansion and upgrades to meet growing demand and technological advancements. They must also ensure that the grid operates within established safety and environmental standards.

In many countries, including Finland, the electricity market is unbundled, meaning that generation, transmission, and distribution are carried out by separate companies. The siirtojärjestelmänhaltija operates as a natural monopoly, as building a competing transmission grid is economically unfeasible. Therefore, their operations are typically regulated by national authorities to prevent abuse of market power and to ensure fair access for all electricity producers and consumers. The siirtojärjestelmänhaltija plays a crucial role in the functioning of the national electricity system and the broader energy market.
