Carbón II

Coal power plant in Coahuila, Mexico. Approximate location 28.4682, -100.7003.

CoalCoahuilaMexicosubcriticalCO₂ modelled

Carbón II is a 1,400 MW coal power station in Coahuila, Mexico. It is operated by CFE. Based on its capacity (estimated), it can supply roughly 1.8 million homes (estimated). It ranks #10 of 366 Mexico power plants by installed capacity. Commissioned in 1993, it is around 33 years old — long-established. Its modelled annual emissions are 4,448,700 t CO₂/yr (Climate TRACE), equivalent to about 1.0 million cars driven for a year. In context, coal supplies about 3.0% of Mexico's electricity; the national grid averages 474 gCO₂/kWh (25.9% low-carbon) (2025).

In context: how this plant compares

Technically it is described as subcritical. 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.

~4,448,700 t CO₂/yr (modelled) — in everyday terms

This facility's annual emissions are roughly equivalent to:

1.0 millionpassenger cars driven for a year
580khomes' yearly energy use
74 milliontree seedlings grown 10 years to absorb it

Equivalencies via US EPA Greenhouse Gas Equivalencies; modelled emissions from 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 hot semi-arid steppe climate (Köppen BSh) — Northern Hemisphere, latitude 28.5°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 76% 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: 22/100 — this site sits in the bottom 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.
