LOS MOLINOS II — Argentina

LOS MOLINOS II is a 4.5 MW hydro power plant in Cordoba, Argentina. It is operated by EPEC. Based on its capacity (estimated), it can supply roughly 4.5k homes (estimated). It ranks #242 of 275 Argentina 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 17.1% of Argentina's electricity; the national grid averages 346 gCO₂/kWh (41.6% low-carbon) (2025).

Capacity provenance

The public capacity above is the current source-record value. A 2026 tracker candidate lists 59 MW for Los Molinos I hydroelectric plant, but it is not used as the public primary value until scope is verified (unit vs operating vs installed/project total).

In context: how this plant compares

At 4.5 MW, LOS MOLINOS II is below the median hydro plant in Argentina (42 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 humid subtropical (dry winter) climate (Köppen Cwa) — Southern Hemisphere, latitude 31.8°S — which shapes how much energy it can produce and how its output varies through the year.

Monthly mean temperature

Heating degree-days here run 53% below 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: 28/100 — this site sits in the bottom 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

This site sits in a mild atmospheric environment (estimated ISO 9223 class C2 — Low), with humidity / wetness 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.
