CoalTexasUnited States of AmericaCO₂ reported

Harrington is a 1,080 MW coal power station in Texas, United States of America. It is operated by Southwestern Public Service Co. Based on reported annual generation of 3,735 GWh, it can supply roughly 1,067,200 homes. It ranks #285 of 9,833 United States of America power plants by installed capacity. Commissioned in 1978, it is around 48 years old — long-established. Its measured emissions of 3,465,957 t CO₂/yr (US EPA GHGRP) are equivalent to about 807,915 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 cold semi-arid steppe climate (Köppen BSk) — Northern Hemisphere, latitude 35.3°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 9% 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: 47/100 — 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.
