The Kumeyaay Wind farm annually produces power sufficient for about 30,000 homes and saves approximately 110,000 tons a year in greenhouse gas emissions, compared with equivalent fossil fuel generation. It helps San Diego Gas & Electric meet its target of supplying at least 20 percent of its customers' electricity from renewable sources by 2010.

The 25 power-generating turbines located on Campo tribal lands are maintained under contract with Enxco, Inc.
