Last night, the city of Fremont approved important expansion plans submitted by Tesla, which the automaker refers to as ‘Tesla Master Plan’, back in October. The plan includes the addition of several new buildings that will almost double the size of the already giant electric vehicle factory – 5.3 million square feet to 9.9 million square feet. The expansion is, of course, to support the planned production increase at the factory due to the upcoming Tesla Model 3. After receiving around 400,000 reservations for the Model 3 earlier this year, Tesla announced its plans to achieve a production rate of 500,000 cars per year at the factory by 2018 and that a path to 1 million cars per year could be possible by 2020. After an environmental review, the city approved the plans Monday and yesterday, Mayor Harrison signed the resolution so that Tesla can move forward with the expansion.
