In context: how this plant compares

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.

Climate zone & how it works

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).

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.
