Vallon-Pont-d'Arc is a 1 MW hydro power plant in Rhone-Alpes, France. Based on its capacity (estimated), it can supply roughly 1,201 homes (estimated). It ranks #2067 of 2,217 France power plants by installed capacity. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, hydro supplies about 10.4% of France's electricity; the national grid averages 41 gCO₂/kWh (94.9% low-carbon) (2025).

At 1 MW, Vallon-Pont-d'Arc is below the median hydro plant in France (5 MW). Hydropower converts the energy of falling or flowing water into electricity; output depends on rainfall and reservoir level, and large dams also provide grid balancing and storage.

This hydro plant converts the energy of falling or flowing water through hydro turbines. It sits in a warm-summer Mediterranean climate (Köppen Csb) — Northern Hemisphere, latitude 44.4°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 13% 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: 45/100 — 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.

Plants like this lose energy through hot valves, flanges, steam lines and heat exchangers. Inzonex makes removable, reusable valve, flange & pipe insulation that cuts that loss by up to 90% and holds surface temperatures under 45°C, unclipping in seconds for maintenance.
