Wind Power Introduction
Like hydropower, wind power has been used for centuries, to lift water, propel boats, grind grain. It is an attractive and non-polluting source for electricity. It has only been since the mid 1980s, however, that wind power has contributed appreciably to our supply of electricity. The largest generating capacity in the world at present is in Germany, although Denmark is targeting wind as the source of half of its electricity in the near future, if public opposition to their visual intrusion can be overcome.
Some of the largest "wind farms" in the world area in California. One, that in San Gorgonio Pass, is about 100 miles west of Arizona, near Palm Springs, California, where about 4000 wind turbines convert wind power into electricity power. The other major installations in the US are similarly located in passes where the winds are concentrated. Without such concentration, the density of wind power is usually too low to generate electricity commercially.
Like many other states, Arizona has long used wind power to pump water on ranches. Nowadays, this is not a major use in Arizona. Indeed, few sites in Arizona are consistently windy enough for commercial development. Only northern Arizona (for example, near Winslow) might be commercially attractive. As yet, no projects of this sort are yet in place.

Almost Too Much Wind Power in Europe
It’s Been So Windy in Europe (June 2017) That Electricity Prices Have Turned Negative. See the article Almost Too Much Wind Power in Europe
APS and sPower, a Utah-based company, have proposed the 477-megawatt Chevelon Butte Wind Farm. (2/2020)
The Arizona Daily Sun - The Utah-based company’s proposal was unanimously approved by Navajo County, the Coconino County Planning and Zoning Commission and the Arizona Corporation Commission. This project could build turbines that will be some of the largest structures in the state. Click here for full news story.
APS Wind Integration Study (September 2007)
The final report of the APS Wind Integration Cost Impact Study was produced by Northern Arizona University (NAU), with contributions from EnerNex Corporation, 3TIER, and Arizona Public Service Company (APS). The report is a result of an eight month study to characterize the impacts and costs due to the variability and uncertainty of wind energy associated with integrating wind energy into APS’ utility resources and practices.
