Coal power plant in Ilocos, Philippines. Approximate location 16.1243, 120.1012.
CoalIlocosPhilippines
Sual power station is a 1,218 MW coal power station in Ilocos, Philippines. It is operated by SMC Global Power Holdings Corp.. Based on its capacity (estimated), it can supply roughly 1,524,240 homes (estimated). It ranks #2 of 123 Philippines power plants by installed capacity. Commissioned in 1999, it is around 27 years old — long-established. In context, coal supplies about 58.7% of Philippines's electricity; the national grid averages 588 gCO₂/kWh (23.3% low-carbon) (2025).

This facility's annual emissions are roughly equivalent to:
Estimated, not measured: from installed capacity at a typical 50% load factor × a typical coal emission factor (~1000 g CO₂/kWh, IPCC AR5 / US EIA). Actual emissions depend on plant efficiency and running hours.Equivalencies via US EPA Greenhouse Gas Equivalencies.

This coal plant burns coal to raise high-pressure steam that spins a turbine-generator. It sits in a tropical monsoon climate (Köppen Am) — Northern Hemisphere, latitude 16.1°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.
