Cogeneration power plant in Louisiana, United States of America. Approximate location 30.0386, -90.8283.

CogenerationLouisianaUnited States of AmericaCO₂ reported

Mosaic Phosphates Uncle Sam is a 26 MW cogeneration power plant in Louisiana, United States of America. It is operated by Mosaic Phosphates Co.. Based on reported annual generation of -36 GWh, it can supply roughly -10,228 homes. It ranks #3419 of 9,833 United States of America power plants by installed capacity. Commissioned in 1995, it is around 31 years old — long-established. Its measured emissions of 24,900 t CO₂/yr (Climate TRACE) are equivalent to about 5,804 cars driven for a year. In context, the national grid averages 384 gCO₂/kWh (43.0% low-carbon) (2025).

Local climate & thermal context

This cogeneration plant produces electricity and useful heat together for higher fuel efficiency. It sits in a humid subtropical climate (Köppen Cfa) — Northern Hemisphere, latitude 30.0°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 74% 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: 22/100 — this site sits in the bottom 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.
