Coal power plant in Indiana, United States of America. Approximate location 41.7208, -86.9086.
CoalIndianaUnited States of AmericaCO₂ reported
Michigan City is a 540 MW coal power station in Indiana, United States of America. It is operated by Northern Indiana Pub Serv Co. Based on reported annual generation of 1,073 GWh, it can supply roughly 306,571 homes. It ranks #693 of 9,833 United States of America power plants by installed capacity. Commissioned in 1974, it is around 52 years old — an older, legacy facility. Its measured emissions of 1,477,536 t CO₂/yr (US EPA GHGRP) are equivalent to about 344,414 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 hot-summer humid continental climate (Köppen Dfa) — Northern Hemisphere, latitude 41.7°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 38% 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: 73/100 — 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.
