Petcoke power plant in Michigan, United States of America. Approximate location 45.0699, -83.4082.
PetcokeMichiganUnited States of America
Alpena Cement Plant is a 47 MW petcoke power plant in Michigan, United States of America. It is operated by Lafarge Corp. Based on reported annual generation of 171 GWh, it can supply roughly 48,800 homes. It ranks #2840 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. In context, the national grid averages 384 gCO₂/kWh (43.0% low-carbon) (2025).

This facility's annual emissions are roughly equivalent to:
Estimated, not measured: from reported annual generation × a typical petcoke emission factor (~1050 g CO₂/kWh, IPCC AR5 / US EIA). Actual emissions depend on plant efficiency and running hours.Equivalencies via US EPA Greenhouse Gas Equivalencies.

This petcoke plant generates electricity for the grid. It sits in a warm-summer humid continental climate (Köppen Dfb) — Northern Hemisphere, latitude 45.1°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 62% 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.
