Regional players

• RTE (Réseau de Transport d'Électricité): France's national transmission system operator operates the high-voltage network and balances electricity supply and demand under a regulated framework. It is a close operating and business-model analogue to Terna's Italian concession.
• Red Eléctrica de España: Red Eléctrica operates Spain's national transmission grid and performs system-operation and electricity-market coordination. Its regulated national TSO model is closely comparable to Terna's core activities.
• TenneT: TenneT operates high-voltage transmission networks in the Netherlands and Germany and manages cross-border electricity flows. Its network scale, grid-expansion programme, and regulated TSO economics are highly comparable to Terna's.
• Elia Group: Elia Group operates national transmission systems in Belgium and Germany, including system balancing, grid investment, and offshore interconnection. Its regulated transmission business closely resembles Terna's integrated TSO model.
• Swissgrid: Swissgrid owns and operates Switzerland's extra-high-voltage transmission system and coordinates national and cross-border system security. It is a particularly direct analogue to Terna's ownership, dispatching, and grid-management role.
• 50Hertz: 50Hertz is one of Germany's four transmission system operators, responsible for high-voltage grid operation, renewable integration, and network expansion in northern and eastern Germany. Its national TSO responsibilities are directly comparable with Terna's.
• Statnett: Statnett owns and operates Norway's transmission system, develops the grid, and coordinates system and market operations. Its asset-owner and system-operator model provides a strong Terna comparison.
• Energinet: Energinet operates and develops Denmark's electricity transmission infrastructure and balances the national system. The electricity activities are closely comparable to Terna, while its additional gas-system role makes it slightly broader.
• Austrian Power Grid: Austrian Power Grid is Austria's independent transmission system operator, responsible for grid planning, operation, security, and cross-border electricity exchange. Its national TSO mandate is directly comparable to Terna's core concession.

Broad incumbents

• National Grid: National Grid operates the UK's electricity transmission system alongside broader regulated energy networks in the UK and United States. Its transmission operations overlap directly with Terna, although its overall portfolio is wider and more diversified.
