Construction of Gigafactory 2 is very much underway, and the company still hopes to start churning out products before year's end.

Gigafactory 1, the site in Nevada, is a joint venture with $4.5 billion behind it to date. Panasonic builds the cylindrical battery cells themselves, while Tesla arranges those cells into battery packs before installing them in cars at its Fremont facility in California. The expansion, which was supposed to be completed by 2020 according to Nikkei, would have bumped annual battery capacity from 35 gigawatt-hours to 54. The two companies first signed an agreement in 2009.
