Biomass power plant in Louisiana, United States of America. Approximate location 32.4868, -92.1496.
BiomassLouisianaUnited States of AmericaCO₂ modelled
Plant 31 Paper Mill is a 84.2 MW biomass power plant in Louisiana, United States of America. It is operated by Graphic Packaging International. Based on reported annual generation of 614 GWh, it can supply roughly 175k homes. It ranks #2988 of 10,884 United States of America power plants by installed capacity. Commissioned in 1991, it is around 35 years old — long-established. Its modelled annual emissions are 56,962 t CO₂/yr (Climate TRACE), equivalent to about 13k cars driven for a year. In context, biomass supplies about 1.0% of United States of America's electricity; the national grid averages 384 gCO₂/kWh (43.0% low-carbon) (2025).

Local climate & thermal context
This biomass plant burns organic material (wood, residues) to raise steam for a turbine. It sits in a humid subtropical climate (Köppen Cfa) — Northern Hemisphere, latitude 32.5°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 54% 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: 28/100 — this site sits in the bottom third of the power plants we cover by heating degree-days.
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.
