Terna consults on grid-code protections and data-centre connections
The proposal covers protection settings for synchronous machines and technical connection conditions for data centres at 36 kV and above.
Event / data period: 2026-10-13
Published: · Updated:
Italy’s transmission system operator Terna opened a consultation on 13 October on two new grid-code annexes and related chapter changes. Annex A.85 sets criteria for selecting, coordinating and setting electrical protections for rotating synchronous generators and synchronous compensators connected to networks at 36 kV or above.
Annex A.86 sets technical connection conditions for data centres on high- and extra-high-voltage networks at those voltage levels, including protection, regulation and control systems. Terna is accepting comments until 13 November. The material is a proposal under consultation, not a statement that the revised rules are already in force.
