överföringsnätsoperatören

An överföringsnätsoperatör, commonly referred to as a transmission system operator (TSO) in English, is a key player in the management and operation of an electricity grid within a specific region. In Sweden, the role is regulated by the Energy Markets Inspectorate (Energimarknadsinspektionen, EI) and is responsible for ensuring the secure, reliable, and efficient transmission of electricity across high-voltage power lines. The primary objective of an överföringsnätsoperatör is to maintain grid stability, balance supply and demand, and facilitate the integration of renewable energy sources into the grid.

In Sweden, there are two main överföringsnätsoperatörer: Svenska Kraftnät and E.ON Sverige. Svenska Kraftnät operates the national high-voltage grid, connecting all regions of the country and managing cross-border electricity flows. E.ON Sverige, on the other hand, manages the regional high-voltage grid in parts of southern Sweden. Both operators are subject to strict regulations to ensure fair competition, grid access for all market participants, and compliance with environmental and safety standards.

The responsibilities of an överföringsnätsoperatör include maintaining and expanding the transmission network, ensuring grid security by monitoring and controlling voltage and frequency levels, and coordinating with distribution system operators (DSOs) and other TSOs in neighboring countries. They also play a crucial role in planning for future energy needs, including the integration of new renewable energy projects and the development of smart grid technologies. Through transparent pricing and non-discriminatory access policies, överföringsnätsoperatörer ensure that electricity can flow freely across the grid, supporting both economic growth and environmental sustainability.
