2025 overview
Following a 5.2% decrease in 2024, gas consumption in France experienced a modest further decline of 3% in 2025, reaching a total of 350 TWh. This overall reduction masks significant sectoral differences, with industrial consumption notably falling by 7%. Meanwhile, biomethane production saw a marked increase of 17%, climbing from 11.6 TWh in 2024 to 13.5 TWh in 2025.
The results by sector
Public distribution consumption
Consumption through public distribution networks (residential, tertiary sector and small industry) reached 231 TWh in 2025, continuing its downward trend, with a 3.1% decrease on a climate-adjusted basis. This decline reflects the advances made in energy efficiency, including improved building insulation and the adoption of less energy-intensive equipment, alongside ongoing sobriety efforts.
Consommation des industriels raccordés aux réseaux de transport de gaz
Meanwhile, consumption among industrial users connected to the gas transmission networks fell by 7% following a modest rise of 0.8% in 2024. This decline reflects both enhanced energy efficiency and ongoing pressure from international competition, particularly within the chemicals sector.
Consumption by combined cycle power plants
Consumption by combined cycle power plants increased by 6.8% in 2025, reaching 16.9 TWh. After a considerable decrease in 2024, driven by the resurgence of nuclear production and the gradual expansion of renewable electrical energies, the 2025 increase is primarily attributed to reduced hydropower production and higher electricity exports to neighbouring countries. Gas plays a significant role in the balancing of the electricity network.
Production of biomethane
Biomethane production experienced a significant rise of 17%, climbing from 11.6 TWh in 2024 to 13.5 TWh in 2025, with 802 methanisation plants in operation, up from 731 in 2024.
By the end of 2025, total installed biomethane capacity had reached 15.5 TWh, cementing France’s leading position in Europe.
Summary of transport and supply
In 2025, the French transmission network carried a total of 659 TWh of gas, reaching a consumption peak of 122 GW in January 2025. Gas inflows amounted to 510.7 TWh, marking a 4.9% increase compared to 2024, with LNG terminals accounting for 64% of these inflows.
Injections into underground storage facilities reached 127 TWh, while net exports to neighbouring countries amounted to 157 TWh, underscoring France’s pivotal role in ensuring European energy supply.
