Laramie River Station

Coal power plant in Wyoming, United States of America. Approximate location 42.1089, -104.8825.

CoalWyomingUnited States of AmericaCO₂ measured

Laramie River Station is a 1,710 MW coal power station in Wyoming, United States of America. It is operated by Basin Electric Power Coop. Based on reported annual generation of 9,032 GWh, it can supply roughly 2.6 million homes. It ranks #307 of 10,938 United States of America power plants by installed capacity. Commissioned in 1981, it is around 45 years old — long-established. Its annual emissions of 10,979,532 t CO₂/yr (US EPA GHGRP) are equivalent to about 2.6 million 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).

In context: how this plant compares

At 1,710 MW, Laramie River Station is well above the median coal plant in United States of America (558 MW). Coal plants burn pulverised coal to raise high-pressure steam for a turbine; they run as baseload but are the most carbon-intensive mainstream source and the first targeted for retirement or efficiency retrofits.

Capacity comparison computed from the WRI Global Power Plant Database; fuel-type context is general engineering background.

10,979,532 t CO₂/yr — in everyday terms

This facility's annual emissions are roughly equivalent to:

2.6 millionpassenger cars driven for a year
1.4 millionhomes' yearly energy use
183 milliontree seedlings grown 10 years to absorb it

Equivalencies via US EPA Greenhouse Gas Equivalencies; emissions per US EPA GHGRP (measured for US EPA/EU ETS, modelled for Climate TRACE).

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 42.1°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 47% 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: 78/100 — 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.

Site climate & environmental severity

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.
