CoalMontanaUnited States of AmericaCO₂ reported
Colstrip Energy LP is a 46 MW coal power plant in Montana, United States of America. It is operated by Colstrip Energy LP. Based on reported annual generation of 301 GWh, it can supply roughly 86,000 homes. It ranks #2867 of 9,833 United States of America power plants by installed capacity. Commissioned in 1990, it is around 36 years old — long-established. Its measured emissions of 145,970 t CO₂/yr (Climate TRACE) are equivalent to about 34,026 cars driven for a year. In context, coal supplies about 16.3% of United States of America's electricity; the national grid averages 384 gCO₂/kWh (43.0% low-carbon) (2025).

This coal plant burns coal to raise high-pressure steam that spins a turbine-generator. It sits in a cold semi-arid steppe climate (Köppen BSk) — Northern Hemisphere, latitude 46.0°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 61% above 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: 84/100 — this site sits in the top 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.
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.
The #255 largest coal power plant of 286 in United States of America by capacity.
United States of America has 286 coal power plants in this dataset, together about 249,149 MW of capacity.
