Gas infrastructure: the CRE approves the revised 2026 investment programmes

On 30 July 2026, the French Energy Regulatory Commission published its review of the 2025 investment expenditure of natural gas transmission grid operators and storage operators, and approved their revised programmes for 2026.

For 2025, expenditure actually incurred amounted to €410.0 million for NaTran, against €405.6 million forecast in the revised programme approved in July 2025, and €126.9 million for Teréga in respect of its transmission activity, against €124.1 million forecast.

On the storage side, Storengy spent €223.3 million against €223.2 million forecast, Teréga €39.2 million against €39.8 million forecast, and Géométhane €26.8 million against €34.1 million anticipated.

For 2026, the CRE approves mid-year revised programmes of €528.1 million for NaTran, against €613.6 million initially forecast in March 2026, and €120.8 million for Teréga in transmission, against €120.2 million forecast in February 2026. Storengy is reduced to €195.1 million.

These decisions come against a backdrop in which the trajectory of gas demand determines the sizing of infrastructure, an issue the CRE is examining separately with a 2050 horizon.
