Cogeneration power plant in Louisiana, United States of America. Approximate location 29.6846, -91.4706.
CogenerationLouisianaUnited States of AmericaCO₂ reported
St. Mary Clean Energy Center is a 58 MW cogeneration power plant in Louisiana, United States of America. It is operated by Cleco Power LLC. Based on reported annual generation of 85 GWh, it can supply roughly 24,200 homes. It ranks #2574 of 9,833 United States of America power plants by installed capacity. Commissioned in 2019, it is around 7 years old — recently built. Its measured emissions of 48,747 t CO₂/yr (Climate TRACE) are equivalent to about 11,363 cars driven for a year. In context, the national grid averages 384 gCO₂/kWh (43.0% low-carbon) (2025).

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 29.7°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 76% 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.
