Oil power plant in Guayas, Ecuador. Approximate location -2.2519, -79.91.
OilGuayasEcuadorOCGTMothballed
Central Termica Trinitaria is a 133 MW oil power station in Guayas, Ecuador. It is operated by Electroguayas. Based on reported annual generation of 630 GWh, it can supply roughly 180k homes. It ranks #10 of 34 Ecuador power plants by installed capacity. Commissioned in 1994, it is around 32 years old — long-established. In context, oil supplies about 17.9% of Ecuador's electricity; the national grid averages 159 gCO₂/kWh (79.4% low-carbon) (2025).

At 133 MW, Central Termica Trinitaria is well above the median oil plant in Ecuador (96 MW). Technically it is described as OCGT. Its current lifecycle status is “mothballed” — so it is not yet, or no longer, generating at full output. 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.

This oil plant burns oil or diesel to drive turbines or reciprocating engines. It sits in a tropical savanna climate (Köppen Aw) — Southern Hemisphere, latitude 2.3°S — 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.
For a plant’s outdoor hardware — heat-recovery steam generators (HRSG), expansion joints, valves, flanges and their insulation — the local climate sets how fast unprotected steel and coatings degrade. This site sits in a corrosive environment (estimated ISO 9223 class C4 — High), with humidity / wetness the leading environmental stress.
Higher environmental severity is exactly where protective removable insulation pays back most: a sheltered micro-climate slows corrosion, UV and thermal-cycling damage and extends outdoor hardware service life. This is an indicative site-climate context — not a condition assessment of any specific plant or operator.
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.
