Therma Marine Inc (TMI) 1 power barge power station is a 100 MW oil power station in Maco, Philippines. It is operated by Therma Marine Inc [100%]. Based on its capacity (estimated), it can supply roughly 75k homes (estimated). It ranks #99 of 186 Philippines power plants by installed capacity. Commissioned in 1994, it is around 32 years old — long-established. In context, oil supplies about 0.8% of Philippines's electricity; the national grid averages 588 gCO₂/kWh (23.3% low-carbon) (2025).

At 100 MW, Therma Marine Inc (TMI) 1 power barge power station is well above the median oil plant in Philippines (59 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.

This oil plant burns oil or diesel to drive turbines or reciprocating engines. It sits in a tropical rainforest climate (Köppen Af) — Northern Hemisphere, latitude 7.4°N — which shapes how much energy it can produce and how its output varies through the year.
Climate zone & typical temperatures: Köppen-Geiger world climate classification (Kottek et al. 2006, 0.5° grid).
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 an aggressive, high-corrosion environment (estimated ISO 9223 class C5 — Very high), with marine salt corrosion 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.
The #11 largest oil power plant of 28 in Philippines by capacity.
