"Tesla is currently ahead of schedule on both construction and production at the Gigafactory.  To date, we have built 1.9 million square feet of manufacturing space and have started production in a portion of the facility while equipment installation continues throughout other areas.  As stated previously, we will be building in phases over time and while our original forecast was to begin production in January, 2017, we actually started battery pack production in October, 2015, over a year ahead of schedule."
