The Reno Gazette-Journal reports that the delay is attributed to a change in design plans for the giant $5 billion factory that will produce lithium batteries for Tesla cars. But Tesla spokeswoman Alexis Georgeson denies there's a delay, saying the company's plans are on schedule. A representative of IBEW Local 401 declined comment, citing a non-disclosure agreement with Tesla.
Tesla CEO Elon Musk in September declared Nevada the winner of a high-stakes battle for the factory, which will mass-produce cheaper batteries for its next line of more-affordable electric cars.
