The new construction will span 245,000 sq ft and require an investment of $215.9 million. Building work is due to begin in October and be completed in Q1 of 2024.

The new site is less than two miles away from a new campus Microsoft is developing at 3545 Wiseman Blvd. The company is planning up to five buildings on the site – known as SAT14 totaling around 350,000 sq ft (32,500 sqm) at a cost of more than $200 million.

It is also developing the SAT46 facility; a $140 million, 79,385 sq ft data center at the company's existing Texas Research Park campus on 15000 Block Lambda Drive.

Microsoft opened its first South Central US Azure region in Texas in 2008, which offers three availability zones. It also opened a US Gov Texas Azure region in 2017. As well as office space, it owns 158 acres of land in the Texas Research Park, where it plans to spend $1 billion building one million square foot of data center space.

The company also owns a Chevron Corp data center at 5200 Rogers Road it bought in October 2017.

AWS is also expanding in the city; the company previously filed plans to build three data centers in San Antonio under the project name ‘Blackfish’ that were due for completion at the end of 2021.
