Hydro power plant in Santa Fe, Argentina. Approximate location -31.2567, -61.5203.
HydroSanta FeArgentina
QUEBRADA DE ULLUM is a 45 MW hydro power plant in Santa Fe, Argentina. It is operated by EPSE - ENERGIA PROVINCIAL SOCIEDAD DEL ESTADO. Based on its capacity (estimated), it can supply roughly 45,051 homes (estimated). It ranks #80 of 236 Argentina power plants by installed capacity. Commissioned in 1981, it is around 45 years old — long-established. 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).

This hydro plant converts the energy of falling or flowing water through hydro turbines. It sits in a humid subtropical climate (Köppen Cfa) — Southern Hemisphere, latitude 31.3°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 70% 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: 24/100 — this site sits in the bottom third of the power plants we cover by heating degree-days.
In colder climates, uninsulated hot equipment (boilers, turbines, valves, steam lines) loses proportionally more heat to ambient air — exactly the loss Inzonex modular insulation is designed to cut.
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.
The #24 largest hydro power plant of 50 in Argentina by capacity.
Argentina has 50 hydro power plants in this dataset, together about 10,000 MW of capacity.
