Simplot Phosphates is a 12 MW other power plant in Wyoming, United States of America. It is operated by Simplot Phosphates LLC. Based on reported annual generation of 81 GWh, it can supply roughly 23k homes. It ranks #5504 of 10,938 United States of America power plants by installed capacity. Commissioned in 1986, it is around 40 years old — long-established. In context, the national grid averages 384 gCO₂/kWh (43.0% low-carbon) (2025).

At 12 MW, Simplot Phosphates is below the median other plant in United States of America (22 MW). This facility converts its energy source into electricity for the grid; its capacity, fuel type and location determine its role in the national power mix.
Capacity comparison computed from the WRI Global Power Plant Database; fuel-type context is general engineering background.

This other plant generates electricity for the grid. It sits in a cold semi-arid steppe climate (Köppen BSk) — Northern Hemisphere, latitude 41.5°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 98% 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: 93/100 — this site sits in the top third of the power plants we cover by heating degree-days.
Climate normals: WorldClim 2.1 (1970–2000 monthly normals, 10 arc-min, CC BY 4.0); zone: Köppen-Geiger world climate classification (Kottek et al. 2006, 0.5° grid). Degree-days & heat-demand index computed by PowerAtlas — a modelled heat-demand proxy, not a measured site figure.
For a plant’s outdoor hardware — heat-recovery steam generators (HRSG), expansion joints, valves, flanges and their insulation — the local climate sets how fast unprotected steel and coatings degrade. This site sits in a benign, low-corrosion environment (estimated ISO 9223 class C1 — Very low), with dust abrasion the leading environmental stress.
Higher environmental severity is exactly where protective removable insulation pays back most: a sheltered micro-climate slows corrosion, UV and thermal-cycling damage and extends outdoor hardware service life. This is an indicative site-climate context — not a condition assessment of any specific plant or operator.
Indicative estimate via the ISO 9223:2012 informative method (atmospheric corrosivity from temperature, time-of-wetness and airborne salinity), using WorldClim climate normals, the Köppen-Geiger class and coast distance. Indicative, not a measured corrosion rate.
