Invenergy has filed a notice of intent with the Oregon Energy Facilities Siting Council for the Heppner Wind Energy project, which would spread across some 60,000 acres (243sq km) of private land in Morrow County, a hotbed of wind development between the Columbia River and Blue Mountains in eastern Oregon.

"With an excellent wind resource, the area is an optimal location for a successful wind project," Invenergy says in a statement.
