The pass carries Interstate 580 , heavily congested by Central Valley Suburbanization , and a railroad route, originally owned by Western Pacific and today used for the Altamont Commuter Express with service to Pleasanton , Fremont , and San Jose . WIND FARM The pass is known for its Wind Farm , one of the earliest in the United States . The wind farm is composed of over 6000 relatively small wind Turbine s of various types, making it at one time the largest farm in the world in terms of capacity. Altamont Pass is still the largest concentration of wind turbines in the world. They were installed after the 1970s Energy Crisis in response to favorable tax policies for investors. Considered largely obsolete, these numerous small turbines are being gradually replaced with much larger and more cost-effective units. The small turbines are dangerous to various Raptor s that hunt California Ground Squirrel s in the area. The larger units turn slower and, being elevated higher, are less hazardous to the local wildlife. An advantage of this particular site is that under hot inland ( California Central Valley ) conditions a thermal low is developed that brings in cool coastal marine air through this pass, driving the turbines at a time of maximum need. Unfortunately this is not always reliable and with an inland high pressure condition the entire region can be both hot and windless. At this time additional power must be provided by Natural Gas powered gas turbine Peaker Plant s. EXTERNAL LINKS SEE ALSO
