Swissgrid

Swissgrid is the Swiss national transmission system operator (TSO) responsible for the operation, planning, and development of Switzerland’s high-voltage electricity grid. Its core mandate is to ensure a reliable and secure supply for households, businesses, and public services by coordinating the real-time operation of the grid, maintaining voltage and frequency stability, and organizing maintenance outages with grid users.

Beyond day-to-day operations, Swissgrid conducts long-term grid planning to accommodate changing demand, evolving generation mix, and increasing cross-border power flows. It focuses on grid reliability, security against cyber and physical threats, and compliance with European grid codes and standards.

Cross-border cooperation is a central aspect of Swissgrid’s role. The company coordinates interconnections with neighboring transmission system operators to facilitate electricity trade and grid reliability across Switzerland’s borders with Germany, Austria, France, and Italy. Through its participation in European-wide structures such as the European Network of Transmission System Operators for Electricity (ENTSO-E), Swissgrid contributes to regional grid planning and market integration while aligning with Swiss energy policy and regulatory oversight.

The organization operates as a corporate entity within the Swiss energy landscape and collaborates with cantons, utilities, and market participants on grid modernization, new interconnections, and efficiency initiatives. Its work supports Switzerland’s energy transition goals, the decarbonization of power generation, and the ongoing assurance of security of supply in a changing energy system.
