The U.S. Interior Department awarded a lease for more than 96,400 acres of ocean off the coast of Delaware for an offshore wind farm, while NRG Energy Inc. (NRG), the project’s owner, contemplates selling it.

NRG’s Bluewater Wind unit received a commercial lease for its proposed 450-megawatt wind farm about 11 nautical miles (12.7 miles) from shore, the Interior Department said yesterday in a statement, enough to power more than 100,000 homes.
