Swissgrid

What Swissgrid does

Swissgrid AG, headquartered in Aarau with a secondary grid control room in Prilly, is the statutory national transmission system operator (TSO) of Switzerland, established in 2005 and operating the country's extra-high-voltage grid at 380 and 220 kilovolts. The regulated infrastructure comprises more than 6,700 kilometres of transmission lines, 147 substations, 12,000 pylons, and 41 cross-border interconnections linking Switzerland with Germany, France, Austria, and Italy. Around-the-clock operations are delivered from two control centres that monitor and balance the grid using 40,000 metering points processing roughly 10,000 measured values per second, an N-1 security protocol re-calculated every five minutes, and a Wide Area Monitoring platform synchronized across Europe.

Swissgrid's service portfolio is built on this physical asset base. Core products include grid control room operations, a public Grid Data Portal with real-time and historical metrics, balancing markets for primary, secondary, and tertiary frequency reserves, cross-border congestion management via explicit and implicit auctions, and a pipeline of grid development projects under Strategic Grid 2040 and the Grid Express acceleration programme. Customers are mandatory transmission-grid users: Swiss distribution system operators, large power plant operators (≥150 MVA capacity), balance groups trading electricity and balancing energy, railway operators (notably SBB), and emerging large-scale battery storage and hyperscale data-centre operators.

Swissgrid is a privately held Swiss Aktiengesellschaft under regulatory oversight of the Swiss Federal Electricity Commission (ElCom). Revenue is generated through regulated grid usage charges incorporated into end-consumer electricity bills, balancing energy and capacity services remunerating flexibility providers, and revenues from cross-border capacity auctions conducted via JAO S.A. and joint platforms with EPEX SPOT, GME, and Terna. The December 2024 Switzerland-EU Electricity Agreement provides the legal basis for full integration into the European internal electricity market and ENTSO-E coordination mechanisms.

Revenue model

1. Transmission Grid Usage Charges: Swissgrid charges for the use of the transmission grid. These regulated network charges are incorporated into electricity bills for consumers. The costs for national redispatching are incorporated into the charge for use of the grid. The revenue from auctions to allocate cross-border line capacities is used to pay for costs arising from cross-border redispatching.
2. Balancing Energy Services: Swissgrid procures frequency control products (primary, secondary, and tertiary control reserves) through balancing markets. Power plants and other flexibility providers receive financial remuneration for reserving their flexibility in advance and for activating it in real time when imbalances in the grid need to be corrected.
3. Cross-border Capacity Auctions: Swissgrid awards available capacities on international interconnection lines to traders through explicit auctions held one year, one month and one day (day ahead) before the actual exchange of electricity. Revenue from these auctions covers costs of cross-border redispatching when foreign transmission system operators request support from Swiss power plants.

Partnerships

Ten partnerships are on record, tiered core.

• European Union (Electricity Agreement)coreStrategic or Co-development Partner · 1 December 2024Switzerland and the EU concluded a comprehensive Electricity Agreement in December 2024, providing the legal framework for Switzerland's integration into the European power grid. Swissgrid will join European coordination processes, the agreement prevents import capacity drops of up to 70% in extreme scenarios, and fully opens Switzerland's electricity market to all consumers while aligning with EU energy rules.
• ENTSO-E (European Network of Transmission System Operators for Electricity)coreTechnology or IntegrationSwissgrid participates in ENTSO-E, the European Network of Transmission System Operators for Electricity. ENTSO-E coordinates cross-border electricity grid operations, develops grid development plans, and establishes European market rules. Swissgrid's participation is essential for grid security in Europe and allows coordination on European grid standards and practices.
• European Interconnected Grid Partners (Germany, France, Austria, Italy)coreTechnology or IntegrationSwitzerland is closely networked with neighbouring countries via 41 lines. Swissgrid works with German, French, Austrian, and Italian transmission system operators for cross-border electricity exchange, grid stability coordination, and balancing energy cooperation. On behalf of ENTSO-E, Swissgrid assumes a key role as the coordination centre for Southern Europe to keep the European grid in balance.
• Joint Allocation Office (JAO S.A.)coreChannel Partner/ Reseller/ DistributorSwissgrid participates in the Joint Allocation Office (JAO S.A.), in which Swissgrid and several other transmission system operators hold participating interests. JAO holds explicit auctions for awarding cross-border transmission capacity at all Swiss borders for year-ahead, month-ahead, and day-ahead trading timeframes.
• Capacity Calculation Regions CORE and Italy NorthcoreTechnology or IntegrationSwissgrid cooperates with the CORE and Italy North capacity calculation regions through contracts under private law due to the lack of an electricity agreement. These partnerships coordinate the calculation of cross-border capacity across the entire region. An electricity agreement would allow Switzerland to be automatically included in capacity calculation methods.
• International Grid Control Cooperation (IGCC)coreTechnology or IntegrationSwissgrid participates in the International Grid Control Cooperation (IGCC), in which the imbalances between generation and consumption in different regions are balanced. This international cooperation arrangement helps maintain grid stability across borders.
• PRL Cooperation (Primary Control Reserves)coreTechnology or IntegrationSwissgrid procures primary balancing capacity (PRL) on a common market with other transmission system operators as part of PRL cooperation. Primary reserves are distributed throughout continental Europe and serve to stabilise grid frequency automatically and without delay.
• EPEX SPOT and GMEcoreChannel Partner/ Reseller/ DistributorAt the Switzerland-Italy border, Swissgrid and the Italian transmission system operator Terna jointly hold implicit auctions with the EPEX SPOT and GME electricity exchanges. In implicit auctions, traders buy or sell energy in their domestic market without purchasing capacity separately.
• Terna (Italian Transmission System Operator)coreTechnology or IntegrationSwissgrid works with Terna, the Italian transmission system operator, for cross-border electricity exchange at the Switzerland-Italy border. Together they manage implicit auctions and coordinate grid operations to ensure security of supply for Italy as an important transit country.
• SBB (Swiss Federal Railways)coreTechnology or IntegrationSBB's railway power system is connected to the transmission grid to ensure the supply of energy for rail transport. Combined with SBB's own railway power system, this connection guarantees a stable and reliable supply of electricity for Swiss rail transport.

Broad incumbents

• Red Eléctrica de España: Red Eléctrica is Spain's TSO with a similar regulated utility model and ENTSO-E membership. Comparable as a national TSO across all of Swissgrid's core functions (transmission, system operation, balancing markets) though operating in a larger and more isolated (Iberian) market.
• National Grid ESO (UK): National Grid ESO operates the Great Britain transmission system and balancing mechanism. Comparable to Swissgrid in operating a national grid, running balancing markets, and managing system frequency, although the UK market is increasingly disconnected from continental Europe post-Brexit.

Direct peers

• RTE (Réseau de Transport d'Électricité): RTE is France's national transmission system operator, managing the largest European grid by capacity and operating Swiss-French cross-border lines. Comparable to Swissgrid as a regulated TSO with cross-border interconnections, balancing markets operation, and ENTSO-E participation.
• TenneT: TenneT is a major European TSO operating in the Netherlands and Germany, with cross-border interconnections and large offshore wind integration programmes. Comparable in scale and scope to Swissgrid's transmission operations and is a PRL/IGCC partner for cross-border balancing.
• 50Hertz Transmission: 50Hertz is a German TSO (Elia Group subsidiary) operating the transmission grid in northern/eastern Germany with significant renewable integration challenges. Directly comparable to Swissgrid's balancing, wind/PV integration, and ENTSO-E coordination functions, and a PRL cooperation partner for primary control reserves.
• Amprion: Amprion operates Germany's largest extra-high-voltage transmission grid (~11,000 km) as a regulated TSO. Comparable to Swissgrid in that it runs cross-border interconnection capacity, procures balancing services, and partners in PRL/IGCC cooperation; it is one of Swissgrid's principal neighbours for cross-border redispatching and balancing cooperation.
• APG (Austrian Power Grid): APG is Austria's TSO and a direct neighbour of Swissgrid at the CH-AT border with shared PRL cooperation and cross-border capacity allocation. Comparable in scope (single-country extra-high-voltage TSO) and in scope of services (transmission, balancing, market facilitation).
• TransnetBW: TransnetBW is the Baden-Württemberg TSO at the German-Swiss border and a direct operational counterpart to Swissgrid for cross-border interconnection lines and redispatching. Highly comparable in scope (single-state TSO) and value proposition (regulated transmission, balancing markets participation).
• Terna: Terna is Italy's national transmission system operator, operating the extra-high-voltage grid and participating in ENTSO-E alongside Swissgrid. As the partner at the CH-IT border (explicit/implicit auctions, redispatching), Terna is the most directly comparable peer, with an almost identical TSO business model, regulatory framework and cross-border coordination role.

Regional players

• Energinet: Energinet operates the Danish electricity and gas transmission systems. Comparable to Swissgrid in TSO function but on a smaller, regionally focused footprint with strong wind integration — making it a relevant peer for the renewable-balancing and interconnection dimensions of Swissgrid's portfolio.
