The Navajo Nation, Window Rock, Ariz., says it will build a $200-million wind farm near Flagstaff, Ariz., in conjunction with San Francisco-based Foresight Wind Energy and Edison Mission Energy.

The Navajo Tribal Utility Authority, Fort Defiance, Ariz., confirmed that plans for the wind farm on the Big Boquillas Ranch were approved by the Navajo Nation Council last week.

As part of the approved plan, the Navajo Nation will construct a 48-turbine array on the targeted farm lands by December 2011. The planned 85MW wind farm is expected to produce enough electricity when at full capacity to power more than 20,200 homes.
