CHEYENNE, Wyo. (AP) — What could become the largest wind energy project in the U.S. has received approval from Wyoming regulators but still awaits completion of federal environmental reviews.

The Industrial Siting Council voted 7-0 Wednesday to approve Power Company of Wyoming's proposal to build up to 1,000 turbines in Carbon County in south-central Wyoming.

Siting council chairman Shawn Warner says that the company did a first-class job with its permit application.

The $5 billion Chokecherry and Sierra Madre project would produce enough power for 1 million homes. The Power Company is a wholly owned affiliate of Denver billionaire Phil Anschutz's The Anschutz Corp.

The project still has to get approval from the U.S. Bureau of Land Management.
