Hydro power plant in Oklahoma, United States of America. Approximate location 34.1388, -94.6845.
HydroOklahomaUnited States of America
Broken Bow Dam is a 100 MW hydro power station in Oklahoma, United States of America. It is operated by USCE-Tulsa District. Based on reported annual generation of 251 GWh, it can supply roughly 71,828 homes. It ranks #1953 of 9,833 United States of America power plants by installed capacity. Commissioned in 1970, it is around 56 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).

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 34.1°N — which shapes how much energy it can produce and how its output varies through the year.
Monthly mean temperature
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.
