Fos-sur-Mer is a 40 MW biomass power plant in Provence-Alpes-Cote d'Azur, France. It is operated by ArcelorMittal Méditerranée SAS. Based on its capacity (estimated), it can supply roughly 55,751 homes (estimated). It ranks #174 of 2,188 France power plants by installed capacity. Its measured emissions of 136,030 t CO₂/yr (Climate TRACE) are equivalent to about 31,709 cars driven for a year. In context, biomass supplies about 1.8% of France's electricity; the national grid averages 41 gCO₂/kWh (94.9% low-carbon) (2025).

This biomass plant burns organic material (wood, residues) to raise steam for a turbine. It sits in a hot-summer Mediterranean climate (Köppen Csa) — Northern Hemisphere, latitude 43.5°N — which shapes how much energy it can produce and how its output varies through the year.
Monthly mean temperature
Heating degree-days here run 37% below the median power plant in this dataset — a proxy for how much extra energy heated equipment must replace through its surfaces in winter.
Climate heat-demand index: 35/100 — this site sits in the mid third of the power plants we cover by heating degree-days.
In colder climates, uninsulated hot equipment (boilers, turbines, valves, steam lines) loses proportionally more heat to ambient air — exactly the loss Inzonex modular insulation is designed to cut.

The #4 largest biomass power plant of 158 in France by capacity.
France has 158 biomass power plants in this dataset, together about 1,127 MW of capacity.
