Italy Records Highest July Electricity Demand Ever

Italy's electricity demand reached an all time high for the month of July, totaling 32.5 TWh. This represents an 8.3 percent increase compared to July 2025, according to data from Terna. Exceptionally high temperatures drove this surge, which also pushed the annual demand peak to approximately 58 GW on July 15, a 4.5 percent increase over the previous year's peak.

Industrial consumption showed positive growth. The Imcei index, which monitors approximately 1,000 energy intensive companies, rose by 2.1 percent in July compared to the same period last year and grew by 4 percent between January and July 2026. National production covered 84.4 percent of the total demand, while the remaining 15.6 percent was met through foreign trade.

Solar power saw significant growth, producing 6.7 TWh in July, which is a 20.6 percent increase over July 2025. This growth was primarily driven by an increase in installed capacity, which rose by 3,791 MW from January to July 2026. Despite the solar boom, other renewable sources declined, including wind, hydroelectric, geothermal, and biomass. Overall, renewable sources covered 41.5 percent of the total electricity requirement.

While both reports focus on the record demand and the rise of solar energy, they differ in detail. The center leaning report presents the data as a straightforward record of demand and renewable growth. The center right leaning report provides a more detailed economic and climatic analysis, noting that demand grew by 5.1 percent even when adjusted for temperature and calendar effects, and highlighting that thermoelectric generation increased by 14.1 percent to meet the high demand.
