Terna (ISIN IT0003242622) was trading at EUR 9.47 at Lang & Schwarz on October 22, 2026 at 9:17 a.m. CEST, up 1.07 percent versus the Xetra close of October 21, 2026 at EUR 9.37. The latest operating signal is a 6.5 percent annual increase in Italian electricity demand to 27.8 TWh in September, according to MarketScreener on October 21, 2026.

Demand reaches a 12-year high

The September figure was the highest for that month since 2014. Demand increased for the thirteenth consecutive month, while the temperature-adjusted increase was 4.6 percent, the same report said.

Renewable sources covered 39 percent of national electricity demand in September, with renewable generation at 10.9 TWh. Photovoltaic output rose 27 percent, while hydroelectric generation fell 29 percent. For investors, the data point to sustained grid usage, but the mix also shows that weather-sensitive generation can move in opposite directions.

Three dated operating milestones

On May 11, 2026, Terna's first-quarter results showed revenue of EUR 988.70 million, up 9.60 percent from the first quarter of 2025, according to Simply Wall St. On July 30, 2026, second-quarter revenue reached EUR 1.12 billion, up 13.00 percent year over year, while net income was EUR 314.70 million.

On October 21, 2026, the September demand report added a current operating marker with 27.8 TWh of consumption and 39 percent renewable coverage. The sequence shows faster revenue growth in the first half of 2026 alongside stronger electricity use later in the year.

What does demand mean for Terna?

The data matter because Terna operates Italy's electricity transmission and dispatching system. Its regulated network remains the core business, while demand growth and renewable generation increase the need for transmission capacity and system balancing. The September renewable share of 39 percent provides a concrete measure of that changing system mix.

Next reporting date

Terna's next listed reporting date is November 12, 2026, for third-quarter results, according to MarketScreener. That release will provide the next reported test of whether the first-half revenue trend continued into the third quarter.
