CaÑon del Pato

Hydro power plant in Ancash, Peru. Approximate location -8.813, -77.8526.

HydroAncashPerurun-of-river

CaÑon del Pato is a 247 MW hydro power station in Ancash, Peru. It is operated by Duke Energy Egenor S en C por A.. Based on reported annual generation of 1,580 GWh, it can supply roughly 451k homes. It ranks #11 of 40 Peru power plants by installed capacity. Commissioned in 1958, it is around 68 years old — an older, legacy facility. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, hydro supplies about 56.1% of Peru's electricity; the national grid averages 238 gCO₂/kWh (63.6% low-carbon) (2025).

In context: how this plant compares

At 247 MW, CaÑon del Pato is well above the median hydro plant in Peru (152 MW). Technically it is described as run-of-river. 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 polar tundra climate (Köppen ET) — Southern Hemisphere, latitude 8.8°S — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 61% above the median power plant in this dataset — a proxy for how much extra energy heated equipment must replace through its surfaces in winter.

Climate heat-demand index: 84/100 — this site sits in the top third of the power plants we cover by heating degree-days.

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

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 mild atmospheric environment (estimated ISO 9223 class C2 — Low), with heat / UV 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.
