Arizona Vapor — Guatemala

Arizona Vapor is a 170 MW oil power station in Escuintla, Guatemala. It is operated by Nautilus Inkia Holdings LLC [100%]. Based on reported annual generation of 4 GWh, it can supply roughly 1.2k homes. It ranks #4 of 77 Guatemala power plants by installed capacity. Commissioned in 2008, it is around 18 years old — relatively modern. In context, oil supplies about 15.8% of Guatemala's electricity; the national grid averages 301 gCO₂/kWh (68.3% low-carbon) (2024).

In context: how this plant compares

At 170 MW, Arizona Vapor is well above the median oil plant in Guatemala (44 MW). Technically it is described as Engine. Oil-fired plants burn heavy fuel oil or diesel, usually as peaking or backup capacity on islands and grids without gas pipelines; high fuel cost keeps their utilisation low.

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

Local climate & thermal context

This oil plant burns oil or diesel to drive turbines or reciprocating engines. It sits in a tropical savanna climate (Köppen Aw) — Northern Hemisphere, latitude 14.0°N — which shapes how much energy it can produce and how its output varies through the year.

Monthly mean temperature

This site has effectively no heating season (tropical/equatorial climate), so winter heat loss is not the driver here. The thermal concern shifts to year-round process heat and humidity/heat-driven corrosion of hot equipment.

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 an aggressive, high-corrosion environment (estimated ISO 9223 class C5 — Very high), with marine salt corrosion 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.
