Samalayuca II

Gas power plant in Texas, Mexico. Approximate location 31.3276, -106.4841.

GasTexasMexicoCO₂ reported

Samalayuca II is a 522 MW gas power station in Texas, Mexico. It is operated by CFE. Based on its capacity (estimated), it can supply roughly 587,695 homes (estimated). It ranks #43 of 335 Mexico power plants by installed capacity. Its measured emissions of 2,767,600 t CO₂/yr (Climate TRACE) are equivalent to about 645,128 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).

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 cold semi-arid steppe climate (Köppen BSk) — Northern Hemisphere, latitude 31.3°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 38% 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: 34/100 — this site sits in the mid third of the power plants we cover by heating degree-days.

In colder climates, uninsulated hot equipment (boilers, turbines, valves, steam lines) loses proportionally more heat to ambient air — exactly the loss Inzonex modular insulation is designed to cut.

A gas turbine here also runs ~1% below its ISO (15°C) rating at this annual mean (typical CCGT curve, estimate).
