CoalTexasUnited States of AmericaCO₂ reported
Pirkey is a 721 MW coal power station in Texas, United States of America. It is operated by Southwestern Electric Power Co. Based on reported annual generation of 3,071 GWh, it can supply roughly 877,485 homes. It ranks #477 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 931,067 t CO₂/yr (US EPA GHGRP) are equivalent to about 217,032 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 humid subtropical climate (Köppen Cfa) — Northern Hemisphere, latitude 32.5°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 52% 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: 28/100 — this site sits in the bottom 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.
