Altos Hornos de México — Mexico

Altos Hornos de México is a 180.3 MW gas power station in Coahuila, Mexico. It is operated by Altos Hornos De México S. A. De C. V.. Based on its capacity (estimated), it can supply roughly 203k homes (estimated). It ranks #143 of 366 Mexico power plants by installed capacity. In context, gas supplies about 61.6% of Mexico's electricity; the national grid averages 474 gCO₂/kWh (25.9% low-carbon) (2025).

In context: how this plant compares

At 180.3 MW, Altos Hornos de México is below the median gas plant in Mexico (368 MW). Gas plants burn natural gas either in open-cycle turbines for fast peaking, or in combined-cycle units that recover exhaust heat in an HRSG to reach roughly 55–62% efficiency — the cleanest-burning fossil option.

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

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 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.

Monthly mean temperature

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.

A gas turbine here also runs ~4% below its ISO (15°C) rating at this annual mean (typical CCGT curve, estimate).

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

This site sits in a benign, low-corrosion environment (estimated ISO 9223 class C1 — Very low), with dust abrasion the leading environmental stress.

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.
