An anonymous reader quotes a report from CNET: A joint effort between Tesla and Panasonic, the Gigafactory is a $5 billion project that will create the world's premier battery manufacturing facility. The Gigafactory will not only be physically larger than any other cell-packing plant on the planet, it'll produce more batteries than the entire industry did back in 2013. That's a lot of batteries, enough to meet Tesla's 500,000-per-year manufacturing goals -- and potentially even more. When completed, the factory will cover five million square feet of the desert floor just outside of Reno, Nevada. Right now, the uncompleted but already-operational factory sits on 800,000 square feet. Over the next four years the building will grow and grow again, swelling to its full size while production dials up simultaneously. The roof will be covered in solar panels, with the goal of producing enough electricity to power the entire thing. Tesla is already assembling Powerwall units here, but the first Model 3 battery packs are expected to roll off the line by the middle of next year. From there, Tesla will have to scale quickly to meet the company's Model 3 production goals for 2018. And, once the company does, the cost savings will begin.
