The EBITDA for the Segment at 31 December 2025 was €448.5 million, showing an increase of €13.1 million compared to 31 December 2024. The change is attributable to i) organic tariff growth (+€31.2 million); ii) the release of capital grants (+€10.3 million); iii) and improvement in the margin relating to Public Lighting (+€3.0 million). This change was offset by the reduction in the WACC (5.6% vs 6.0), which impacted negatively for approximately €15.0 million, and the effects from the sale of the high-voltage line to Terna (-€13.9 million), largely from the regulatory credit accounting portion returned to Terna.
As at 31 December 2025, areti had distributed 9,338 GWh of electricity to end customers, up slightly compared to the previous year.
The average number of employees fell slightly compared to the previous year by six units.
Investments amounted to €384.7 million, an increase of €68.2 million compared to last year. The investments referred for the most part to areti and were mainly attributable to the digitalisation of secondary substations and upgrading on the MV and LV networks. Ongoing projects include the replacement of 2G metering groups, work on the primary stations, secondary substations and meters, and remote control equipment as part of the grid “Adequacy and Safety” and “Innovation and Digitalisation” projects.
