Walk into Tesla's Gigafactory in Sparks, Nevada, and the first thing that stands out is the size of the battery plant. It's enormous. So big that you could fit 33 football fields — and it's only getting larger.
"The Gigafactory is critical to Tesla. There is more batteries produced here for electric vehicles than in the rest of the planet combined. We would not be able to make all the vehicles we are making now if we didn't have the Gigafactory," said Jerome Guillen, president of Tesla Automotive.
The Gigafactory's expansion since opening in July 2016 has been critical to Tesla's growth. This year, the automaker is on track to sell 236,000 vehicles. Much of that growth is due to its latest vehicle, the Model 3, a sedan targeted to a broader audience than Tesla's previous cars. All of the Model 3's batteries are built at the Gigafactory.
Last quarter, as Tesla hit its target of producing more than 5,000 Model 3 cars per week, the company posted a profit. CEO Elon Musk says his company has turned the corner after years of mounting losses.
