In context: how this plant compares
At 1,492 MW, Aguirre power station is well above the median oil plant in Puerto Rico (752 MW). Technically it is described as CCGT; combined-cycle with a heat-recovery steam generator (HRSG). 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 17.9°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.
