Gas power plant in Washington, United States of America. Approximate location 46.1388, -122.9855.

GasWashingtonUnited States of AmericaCO₂ reported

Mint Farm Generating Station is a 319 MW gas power station in Washington, United States of America. It is operated by Puget Sound Energy Inc. Based on reported annual generation of 1,865 GWh, it can supply roughly 532,771 homes. It ranks #916 of 9,833 United States of America power plants by installed capacity. Commissioned in 2008, it is around 18 years old — relatively modern. Its measured emissions of 798,750 t CO₂/yr (US EPA GHGRP) are equivalent to about 186,189 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 warm-summer Mediterranean climate (Köppen Csb) — Northern Hemisphere, latitude 46.1°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 9% 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: 54/100 — 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).
