Oil power plant in Catano, United States of America. Approximate location 18.427, -66.1045.
OilCatanoUnited States of America
San Juan CC is a 864 MW oil power station in Catano, United States of America. It is operated by PREPA. Based on its capacity (estimated), it can supply roughly 648,740 homes (estimated). It ranks #382 of 9,833 United States of America power plants by installed capacity. Commissioned in 2009, it is around 17 years old — relatively modern. In context, oil supplies about 0.7% of United States of America's electricity; the national grid averages 384 gCO₂/kWh (43.0% low-carbon) (2025).

This facility's annual emissions are roughly equivalent to:
Estimated, not measured: from installed capacity at a typical 30% load factor × a typical oil emission factor (~750 g CO₂/kWh, IPCC AR5 / US EIA). Actual emissions depend on plant efficiency and running hours.Equivalencies via US EPA Greenhouse Gas Equivalencies.

This oil plant burns oil or diesel to drive turbines or reciprocating engines. It sits in a tropical monsoon climate (Köppen Am) — Northern Hemisphere, latitude 18.4°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 100% 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: 13/100 — this site sits in the bottom 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.
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.
The #8 largest oil power plant of 876 in United States of America by capacity.
United States of America has 876 oil power plants in this dataset, together about 37,143 MW of capacity.
