KUTTIYADI Add ext is a 100 MW hydro power station in Kerala, India. Based on reported annual generation of 269 GWh, it can supply roughly 77k homes. It ranks #858 of 2,225 India power plants by installed capacity. Commissioned in 2010, it is around 16 years old — relatively modern. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, hydro supplies about 8.6% of India's electricity; the national grid averages 670 gCO₂/kWh (26.7% low-carbon) (2025).

In context: how this plant compares
At 100 MW, KUTTIYADI Add ext is well above the median hydro plant in India (80 MW). 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.
Capacity comparison computed from the WRI Global Power Plant Database; fuel-type context is general engineering background.

Local climate & thermal context
This hydro plant converts the energy of falling or flowing water through hydro turbines. It sits in a tropical monsoon climate (Köppen Am) — Northern Hemisphere, latitude 11.5°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.
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.
