Sonzay is a 1 MW biomass power plant in Centre, France. Based on its capacity (estimated), it can supply roughly 1,789 homes (estimated). It ranks #1956 of 2,188 France power plants by installed capacity. 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 temperate oceanic climate (Köppen Cfb) — Northern Hemisphere, latitude 47.5°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 1% above 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: 50/100 — 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.
