Reno, Nev. • Tesla Motors has selected Nevada for a massive, $5 billion factory that it will build to pump out batteries for a new generation of electric cars.

A person with familiar with Tesla's plans said Wednesday that Nevada beat out four other states which were vying for the project.

The person, who spoke on condition of anonymity because no official announcement has been made, said work soon will resume on a site outside Reno.

Nevada Gov. Brian Sandoval's office said only that the governor will make a "major economic development announcement" Thursday afternoon. A Tesla spokesman says company representatives will be at the Capitol for the announcement.

The other finalists were California, Texas, Arizona and New Mexico.
