CoalKentuckyUnited States of AmericaCO₂ reported

A B Brown is a 707 MW coal power station in Kentucky, United States of America. It is operated by Southern Indiana Gas & Elec Co. Based on reported annual generation of 2,470 GWh, it can supply roughly 705,714 homes. It ranks #493 of 9,833 United States of America power plants by installed capacity. Commissioned in 1985, it is around 41 years old — long-established. Its measured emissions of 1,982,201 t CO₂/yr (US EPA GHGRP) are equivalent to about 462,052 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).

Local climate & thermal context

This coal plant burns coal to raise high-pressure steam that spins a turbine-generator. It sits in a humid subtropical climate (Köppen Cfa) — Northern Hemisphere, latitude 37.9°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 7% 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: 48/100 — this site sits in the mid 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.
