GeothermalCalabarzonPhilippines
MAKBAN-Binary is a 16 MW geothermal power plant in Calabarzon, Philippines. Based on its capacity (estimated), it can supply roughly 29k homes (estimated). It ranks #153 of 186 Philippines power plants by installed capacity. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, geothermal supplies about 8.2% of Philippines's electricity; the national grid averages 588 gCO₂/kWh (23.3% low-carbon) (2025).

At 16 MW, MAKBAN-Binary is below the median geothermal plant in Philippines (130 MW). Geothermal plants tap underground heat to raise steam for a turbine; they provide steady, low-carbon baseload but are limited to geologically active regions.

This geothermal plant taps underground heat to raise steam that drives a turbine. It sits in a tropical monsoon climate (Köppen Am) — Northern Hemisphere, latitude 14.1°N — 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.
