In August, electricity demand in Italy reached the highest value ever recorded for this month, standing at 28.9 TWh, an increase of 16.5% compared to August 2025. Terna communicated this by noting that electricity demand is increasing for the fourth consecutive month which brings electricity demand to the highest levels of the last ten years.

The exceptionally high temperatures, which remained constantly higher than those of the same period last year, contributed in particular to supporting the growth in demand.

At night, temperatures, on average, were 5 degrees higher than in August 2025, resulting in greater use of cooling systems.

At a territorial level, the trend change is positive throughout the country: +13.2% in the North, +18.2% in the South and on the islands and +21.7% in the Centre.

In August, production from renewable sources amounted to 12 TWh, covering 41.4% of national electricity needs. In particular, photovoltaic reached 6.2 TWh (+20.4% compared to August 2025), also supported by the increase in installed capacity. With an installed capacity of 88.1 Gw, renewables covered 42.4% of national demand thanks above all to the contribution of photovoltaics (+19.6%).

In August, an increase of 1.1% was recorded for businesses compared to the same month in 2025. In the period January-August 2026, growth was 3.7% compared to the same period last year.
