HydroGeorgiaUnited States of America

Allatoona is a 87 MW hydro power plant in Georgia, United States of America. It is operated by USCE-Mobile District. Based on reported annual generation of 193 GWh, it can supply roughly 55,028 homes. It ranks #2134 of 9,833 United States of America power plants by installed capacity. Commissioned in 1950, it is around 76 years old — an older, legacy facility. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, hydro supplies about 5.3% of United States of America's electricity; the national grid averages 384 gCO₂/kWh (43.0% low-carbon) (2025).

Local climate & thermal context

This hydro plant converts the energy of falling or flowing water through hydro turbines. It sits in a humid subtropical climate (Köppen Cfa) — Northern Hemisphere, latitude 34.2°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 34% 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: 36/100 — this site sits in the mid 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.
