Despite higher supply prices, domestic natural gas consumption recovered in October 2026, reaching 4.86 TWh, up from 4.35 TWh in September, as temperatures dropped. Total consumption from January to October came to 54.8 TWh, the third highest on record for the period, after 2025 and 2021.

The figures come from Green Tank’s Gas Observatory (Gaswatch) for last month.

According to the same data:

  • Industrial consumption continues to fall: The downward trend that began in July continued in October. Overall, industrial consumption over the 10 months was down 16.8% compared with 2025. Refineries and the fertilizer industry recorded their lowest consumption of the year in October. In refineries specifically, gas use over the 10 months fell by 20.8% at Motor Oil and by 26.9% at the Elefsina refineries.
  • Power generation remains high: Despite a 4.3% drop compared with the first 10 months of 2025, gas consumption for power generation was the third highest on record for the period and accounted for 70.7% of total consumption. The Agios Nikolaos II plant remained the largest consumer at 5.7 TWh, followed by Megalopoli V at 4.85 TWh, while the Komotini Thermal Power Plant, the newest unit in the system, rose to third place after increasing its consumption by 51.8% year-on-year.
  • Distribution networks hit a record: Unlike industry and power generation, consumption through distribution networks rose by 5.9% compared with the same period in 2025, reaching a record high of 10.8 TWh. This reflects, among other things, an increase in new connections. The Athens (3.1 TWh), Thessaloniki (2.6 TWh) and Oinofyta (1.47 TWh) networks topped the rankings.
  • LNG leads imports, but Russian gas keeps a significant share: LNG was the main source of gas imports over the 10 months of 2026, at 32.5 TWh. However, Russian gas still covers 31% of net imports (17 TWh), meaning imports intended to meet domestic demand.
  • Exports nearly tripled: Gas exports almost tripled compared with 2025, reaching 15.3 TWh versus 5.7 TWh. Despite this increase, Greece’s net spending (the value of imports minus the value of exports) in the first eight months of 2026 approached 2 billion euros. However, the gap between the value of imports and exports was the lowest for the period in the past five years.
