Largentière is a 10.9 MW solar power plant in Rhone-Alpes, France. Based on its capacity (estimated), it can supply roughly 4.6k homes (estimated). It ranks #761 of 2,216 France power plants by installed capacity. Commissioned in 2014, it is around 12 years old — relatively modern. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, solar supplies about 5.6% of France's electricity; the national grid averages 41 gCO₂/kWh (94.9% low-carbon) (2025).

In context: how this plant compares
At 10.9 MW, Largentière is well above the median solar plant in France (2.7 MW). Technically it is described as PV. Solar PV converts sunlight directly into electricity with no moving parts or fuel; output varies by time of day and weather, so it pairs with storage or flexible backup.
Capacity comparison computed from the WRI Global Power Plant Database; fuel-type context is general engineering background.

Local climate & thermal context
This solar plant converts sunlight directly into electricity with photovoltaic panels. It sits in a temperate oceanic climate (Köppen Cfb) — Northern Hemisphere, latitude 44.5°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 10% 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: 46/100 — this site sits in the mid third of the power plants we cover by heating degree-days.
Solar PV loses ~0.35%/°C above 25°C cell temperature — roughly 0.0% at warm-season highs here (estimate).
Climate normals: WorldClim 2.1 (1970–2000 monthly normals, 10 arc-min, CC BY 4.0); zone: Köppen-Geiger world climate classification (Kottek et al. 2006, 0.5° grid). Degree-days & heat-demand index computed by PowerAtlas — a modelled heat-demand proxy, not a measured site figure.
Site climate & environmental severity
This site sits in a moderately corrosive environment (estimated ISO 9223 class C3 — Medium), with humidity / wetness the leading environmental stress.
Indicative estimate via the ISO 9223:2012 informative method (atmospheric corrosivity from temperature, time-of-wetness and airborne salinity), using WorldClim climate normals, the Köppen-Geiger class and coast distance. Indicative, not a measured corrosion rate.
How it compares & nearby plants
The #116 largest solar power plant of 817 in France by capacity.
