Musk's companies have significant chip requirements of their own. The Terafab website says the factory will have about 100 million square feet of manufacturing space, a scale that could make it the largest building in the world. Texas officials have welcomed the investment as Musk's companies expand their presence in the state. Greg Abbott said the first phase of the Terafab project represents an investment of more than $16.8 billion and will create 3,000 new jobs. According to the Terafab website, the facility plans to use water from a nearby reservoir rather than relying on local groundwater.
