Tesla partners with Panasonic for its gigafactory
Tesla and Panasonic have shook hands and formed a partnership for an eventual gigafactory. We still don't know where the factory will be built, but Panasonic has agreed to invest $300 million in the plant.
The gigafactory is to be built and ready by 2017. By 2020 Tesla says that the plant will be producing enough batteries to handle up to 500,000 electric vehicles each year. The factory will start small and build up as demand increases.
As far as the location of the factory, the lead candidate is the Tahoe-Reno Industrial Center near Reno, Nevada. There is also a former Naval weapons station northeast of San Francisco is apparently still in the running.
