Saltillo — Mexico
Gas power plant in Coahuila, Mexico. Approximate location 25.5939, -100.9164.
GasCoahuilaMexicoCCGT · HRSGCO₂ modelled
Saltillo is a 247.5 MW gas power station in Coahuila, Mexico. It is operated by CFE/PIE. Based on its capacity (estimated), it can supply roughly 279k homes (estimated). It ranks #128 of 366 Mexico power plants by installed capacity. Commissioned in 2001, it is around 25 years old — relatively modern. Its modelled annual emissions are 600,010 t CO₂/yr (Climate TRACE), equivalent to about 140k cars driven for a year. 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 247.5 MW, Saltillo is below the median gas plant in Mexico (368 MW). Technically it is described as CCGT; combined-cycle with a heat-recovery steam generator (HRSG). 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.

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 25.6°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 69% 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: 24/100 — this site sits in the bottom third of the power plants we cover by heating degree-days.
A gas turbine here also runs ~1% 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.
