HydroOregonUnited States of America

Juniper Ridge Hydroelectric Project is a 5 MW hydro power plant in Oregon, United States of America. It is operated by Central Oregon Irrigation Dist. Based on reported annual generation of 12 GWh, it can supply roughly 3,400 homes. It ranks #5805 of 9,833 United States of America power plants by installed capacity. Commissioned in 2010, it is around 16 years old — relatively modern. 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 warm-summer Mediterranean climate (Köppen Csb) — Northern Hemisphere, latitude 44.1°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 80% above 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: 90/100 — this site sits in the top 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.
