COOS BAY, Ore. — A renewable energy project that proposed installing wind turbines 15 miles off the Oregon coast appears to have stalled. Oregon Public Broadcasting reported that the federal Bureau of Ocean Management is no longer processing Principle Power’s lease application, at the company’s request. The bureau says the lease application has not formally been withdrawn. In 2013, Principle Power proposed the first offshore wind project on the West Coast in federal waters about 15 miles from Coos Bay.
