Mariveles Solar — Philippines

Mariveles Solar is a 16 MW solar power plant in Central Luzon, Philippines. It is operated by Next Generation Power Technology Corporation. Based on its capacity (estimated), it can supply roughly 6.8k homes (estimated). It ranks #152 of 186 Philippines power plants by installed capacity. Commissioned in 2017, it is around 9 years old — relatively modern. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, solar supplies about 2.4% of Philippines's electricity; the national grid averages 588 gCO₂/kWh (23.3% low-carbon) (2025).

In context: how this plant compares

At 16 MW, Mariveles Solar is around the median solar plant in Philippines (16 MW). Solar PV converts sunlight directly into electricity with no moving parts or fuel; output varies by time of day and weather, so it pairs with storage or flexible backup.

Capacity comparison computed from the WRI Global Power Plant Database; fuel-type context is general engineering background.

Local climate & thermal context

This solar plant converts sunlight directly into electricity with photovoltaic panels. It sits in a tropical savanna climate (Köppen Aw) — Northern Hemisphere, latitude 14.5°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.

Solar PV loses ~0.35%/°C above 25°C cell temperature — roughly 1.2% at warm-season highs here (estimate).

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.

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.
