Riam Kanan/pangeran Muhamad Nur is a 30 MW hydro power plant in South Kalimantan, Indonesia. It is operated by PLN. Based on its capacity (estimated), it can supply roughly 30k homes (estimated). It ranks #356 of 401 Indonesia power plants by installed capacity. Commissioned in 1973, it is around 53 years old — an older, legacy facility. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, hydro supplies about 7.3% of Indonesia's electricity; the national grid averages 680 gCO₂/kWh (18.1% low-carbon) (2024).

At 30 MW, Riam Kanan/pangeran Muhamad Nur is around the median hydro plant in Indonesia (30 MW). Technically it is described as unknown. Hydropower converts the energy of falling or flowing water into electricity; output depends on rainfall and reservoir level, and large dams also provide grid balancing and storage.

This hydro plant converts the energy of falling or flowing water through hydro turbines. It sits in a tropical rainforest climate (Köppen Af) — Southern Hemisphere, latitude 3.5°S — 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 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.
