Gas consumption for power generation hits decade high in Greece

Natural gas consumption in Greece has significantly increased this year. According to Green Tank data, the first nine months of 2025 recorded the second-highest historical natural gas consumption (51.3 TWh) since 2021. Demand specifically for electricity generation reached a decade-high, hitting 36.5 TWh, or 71% of the market. Overall natural gas consumption rose by 7.7% year-on-year, driven primarily by power producers (+10%) as well as households and businesses (+18%). In contrast, industrial consumption dropped by 18.4%. Unsurprisingly, gas imports rose by 1.9%. Liquefied natural gas (LNG) dominated the market, accounting for 44.1% of supply—a yearly increase of 81.1%. Meanwhile, Russian gas imports via Sidirokastro fell by 20.1%, dropping to second place with a 40.1% share. However, in September 2025, pipeline imports of Russian gas regained the lead with 2.51 TWh—up 53% from August. The last time Russian gas imports surpassed LNG was during April–May 2025.
