Gas power plant in Missouri, United States of America. Approximate location 36.8682, -89.8402.

GasMissouriUnited States of AmericaCO₂ reported

Essex is a 121 MW gas power station in Missouri, United States of America. It is operated by Associated Electric Coop Inc. Based on reported annual generation of 37 GWh, it can supply roughly 10,657 homes. It ranks #1723 of 9,833 United States of America power plants by installed capacity. Commissioned in 1999, it is around 27 years old — long-established. Its measured emissions of 49,053 t CO₂/yr (US EPA GHGRP) are equivalent to about 11,434 cars driven for a year. In context, gas supplies about 40.0% of United States of America's electricity; the national grid averages 384 gCO₂/kWh (43.0% low-carbon) (2025).

Local climate & thermal context

This gas plant burns natural gas in a turbine — often in a combined-cycle setup — to generate electricity. It sits in a humid subtropical climate (Köppen Cfa) — Northern Hemisphere, latitude 36.9°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 12% 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: 45/100 — 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.

A gas turbine here also runs ~0% below its ISO (15°C) rating at this annual mean (typical CCGT curve, estimate).
