Hatchet Ridge Wind Project — United States of America
Wind power plant in California, United States of America. Approximate location 40.8981, -121.8036.
WindCaliforniaUnited States of America
Hatchet Ridge Wind Project is a 101.2 MW wind power station in California, United States of America. It is operated by Pattern Operators LP. Based on reported annual generation of 252 GWh, it can supply roughly 72k homes. It ranks #2727 of 10,884 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, wind supplies about 10.3% 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 101.2 MW, Hatchet Ridge Wind Project is well above the median wind plant in United States of America (67.7 MW). Wind turbines convert moving air into electricity; output is variable and site-dependent, and modern turbines deliver some of the lowest-cost new generation on many grids.
Capacity comparison computed from the WRI Global Power Plant Database; fuel-type context is general engineering background.

Local climate & thermal context
This wind plant converts the kinetic energy of wind into electricity through turbine rotors. It sits in a warm-summer Mediterranean climate (Köppen Csb) — Northern Hemisphere, latitude 40.9°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 50% 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: 80/100 — this site sits in the top third of the power plants we cover by heating degree-days.
Climate normals: WorldClim 2.1 (1970–2000 monthly normals, 10 arc-min, CC BY 4.0); zone: Köppen-Geiger world climate classification (Kottek et al. 2006, 0.5° grid). Degree-days & heat-demand index computed by PowerAtlas — a modelled heat-demand proxy, not a measured site figure.
Site climate & environmental severity
This site sits in a mild atmospheric environment (estimated ISO 9223 class C2 — Low), with humidity / wetness the leading environmental stress.
Indicative estimate via the ISO 9223:2012 informative method (atmospheric corrosivity from temperature, time-of-wetness and airborne salinity), using WorldClim climate normals, the Köppen-Geiger class and coast distance. Indicative, not a measured corrosion rate.
