A total of 68 data centers are currently operating or in the planning stage within a 50-mile radius of San Antonio, according to a database recently collated by the Texas Tribune.

More than half of the San Antonio-area facilities listed in the database haven't reported the amount of energy they require to operate.

However, those that did release that information will require a combined 2,896 megawatts, or enough energy to power 2 million to 3 million homes.
