France — Energy Infrastructure

OverWatts maps 304 energy assets in France across 12 layers — the 30th-largest mapped base of 157 countries. They include 173 power plants, 52 cement plants and 18 LNG terminals. Operating generation capacity is 97.3 GW, led by nuclear at 68%. Refining capacity is about 772 kb/d.

The companies named on the most assets are Electricité de France SA (55), EDF Energy Ltd (50) and Holcim AG (14), counting both ownership and operatorship. Half of France's mapped assets in service predate 1980 (median commissioning year of the 179 with a known date), 24 came online in the past decade and the oldest still listed is Novasco Hagondange steel plant, dating from 1912. 40+ projects are under construction or proposed, led by France – United Kingdom interconnection (planned) (4.9 GW).
