Solar power plant in Oregon, United States of America. Approximate location 45.1089, -123.2786.
SolarOregonUnited States of America
Yamhill Solar LLC is a 1 MW solar power plant in Oregon, United States of America. It is operated by EDF Renewable Asset Holdings Inc.. Based on reported annual generation of 1 GWh, it can supply roughly 342 homes. It ranks #9831 of 9,833 United States of America power plants by installed capacity. Commissioned in 2011, it is around 15 years old — relatively modern. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, solar supplies about 8.6% of United States of America's electricity; the national grid averages 384 gCO₂/kWh (43.0% low-carbon) (2025).

This solar plant converts sunlight directly into electricity with photovoltaic panels. It sits in a warm-summer Mediterranean climate (Köppen Csb) — Northern Hemisphere, latitude 45.1°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 2% 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: 51/100 — 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.
Solar PV loses ~0.35%/°C above 25°C cell temperature — roughly 0.0% at warm-season highs here (estimate).

The #3281 largest solar power plant of 3283 in United States of America by capacity.
United States of America has 3283 solar power plants in this dataset, together about 37,970 MW of capacity.
