Power 'quality' is why SpaceX's Terafab is going with on-site gas, analysts say

SpaceX's plan to build the world's largest facility -- 100 million square feet in Grimes County, Texas, near Houston -- to do advanced computing and also manufacture, test and package silicon chips for its own use and by other Elon Musk-owned companies, will be self-powered using a gigawatt-scale natural gas power plant and battery storage, according to the company.The operations "are not expected to use electricity from the grid," the company said in a tax abatement agreement it entered into with the county in June.
