Italgas distributed 7.45 billion cubic meters of gas domestically in Italy and also in Greece in H1, a 32.2% increase from a year earlier, according to its H1 results on Monday.
The figures came in higher despite a 2.2% shrinkage of the gas distribution network to about 153,000 kilometers, data showed.
The company said its technical investments rose to 765.2 million euros ($871.05 million) in H1, up 54.6% from the same period of 2025, as allocations toward the distribution network increased with the acquisition of 2i Rete Gas.
During the period, Italgas's energy consumption at a constant perimeter decreased year over year by 14.4% to 206.3 terajoules, driven by lower fossil fuel energy use by industry.
"The reduction is the result of the continuation of efficiency interventions on the Group's plants: replacement of natural gas preheating boilers, installation of gas preheating section optimization systems, management of pressure let-down energy recovery plants and digitalization of monitoring and control processes," the company said.
Meanwhile, electricity consumption steadied year over year at around 33 TJ, according to Italgas.
