Terna: core business model

Terna operates and develops Italy's high-voltage electricity transmission grid, managing over 74,000 km of lines. As the sole transmission system operator (TSO), it ensures reliable power flow across the national network, independent from generation and distribution activities. This monopoly position stems from its 1999 founding following the unbundling of Enel, positioning Terna as a key enabler of Italy's energy transition toward renewables.

The company's business model centers on regulated asset base returns, where investments in grid upgrades yield stable revenues approved by regulators. Terna also provides ancillary services like frequency control and grid planning, supporting the integration of solar and wind power into the system, Terna website as of May 2026.
