Tesla had originally planned a production capacity of 35 GWh of battery cells and battery pack production of 50 GWh at the Gigafactory 1. Tesla now plans that capacity for 2018 and will triple that production level to 105 GWh worth of cells and 150 GWh for battery packs for full production around 2020.

Tesla Motors Gigafactory 1 (GF1) is the world's leading battery production facility, maintaining high efficiency and output while achieving the lowest capital investment per gigawatt hour (GWh) and the lowest production cost per kilowatt hour (kWh). The factory will produce cells, battery packs, energy storage products and vehicle components. Phase 2 construction, currently underway, will support annualized cell production capacity of 35 GWh and battery pack production of 50 GWh. The cell capacity represents more than the 2013 total global production of lithium-ion battery cells of all other manufacturers combined and supports the production of about 500,000 cars. Pack production capacity supports both our vehicle and energy product lines (Powerwall 2 and Powerpack 2).
