New natural gas connections in Greece rose by 28 percent in the first half of 2025 compared to the same period last year. Thessaly led the growth with a 48 percent increase, followed by Thessaloniki at 42 percent. Other regions averaged 30 percent growth, while the greater Athens area recorded a more modest 12 percent rise.
This growth continued despite the introduction of a uniform pricing framework on December 1, 2024, which eliminated regional disparities in network charges for households and businesses. Italgas, parent company of Greek gas distributor Enaon EDA, noted that the reform has not slowed the pace of new connections and aims to level costs across areas with differing infrastructure development.
Gas consumption in major industrial zones such as Thessaloniki, Thessaly, greater Athens, central Macedonia, mainland Greece, and the Peloponnese is expected to grow steadily at around 2 percent annually through 2026. Meanwhile, less developed areas are experiencing significant drops in industrial gas prices: western Greece down 8.7 percent, western Macedonia down 34.4 percent, and Epirus down 20.4 percent. These regions—along with eastern Macedonia and Thrace—are set to benefit from an additional average tariff reduction of 7.7 percent in 2026.
