Davis Dam — United States of America

Hydro power plant in Nevada, United States of America. Approximate location 35.197, -114.5707.

HydroNevadaUnited States of America

Davis Dam is a 254.8 MW hydro power station in Nevada, United States of America. It is operated by U S Bureau of Reclamation. Based on reported annual generation of 1,034 GWh, it can supply roughly 295k homes. It ranks #1723 of 10,884 United States of America power plants by installed capacity. Commissioned in 1951, it is around 75 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).

In context: how this plant compares

At 254.8 MW, Davis Dam is well above the median hydro plant in United States of America (8 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 hot desert climate (Köppen BWh) — Northern Hemisphere, latitude 35.2°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 60% 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: 26/100 — this site sits in the bottom third of the power plants we cover by heating degree-days.
