CoalCoahuilaMexicosubcritical
GMéxico Project is a 450 MW coal power station in Coahuila, Mexico. It is operated by Grupo México SAB de CV [100%]. Based on its capacity (estimated), it can supply roughly 563k homes (estimated). It ranks #81 of 366 Mexico power plants by installed capacity. In context, coal supplies about 3.0% of Mexico's electricity; the national grid averages 474 gCO₂/kWh (25.9% low-carbon) (2025).

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.

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 27.9°N — which shapes how much energy it can produce and how its output varies through the year.
Climate zone & typical temperatures: Köppen-Geiger world climate classification (Kottek et al. 2006, 0.5° grid).
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.
The #4 largest coal power plant of 4 in Mexico by capacity.
Mexico has 4 coal power plants in this dataset, together about 5,828 MW of capacity.
