San Antonio III – VII

Stream’s third San Antonio campus is scheduled to support 1.5 million square feet of data center space with a $400M investment, supporting 200 MWc at full build.

This first facility on the new campus, San Antonio III, is currently under construction for 300,000 initial square feet of turnkey data center space and an on-site 334 MW CPS substation, scheduled for occupancy in 2Q 2025.

The Market

Why San Antonio

We invest in your success through speculative development in markets where we see future demand and in locations where TCO can be optimized, risk is low, network connectivity is robust, and sustainability is easily achievable. San Antonio certainly fits the bill.

Relatively low-cost power keeps TCO low
Electricity prices in San Antonio are among the lowest in the U.S. Power is provided by the nation’s largest municipal utility, CPS Energy.

Renewable energy options ­and incentives abound
There are more financial incentives and regulatory policies promoting renewable energy in Texas than any other state except California and Minnesota. By far the largest single renewable energy source in the state is wind. About 28% of all the U.S. wind-powered electricity was produced in Texas.

Natural disaster risk is relatively low
Compared to other cities in Texas and across the U.S., when it comes to natural disasters, San Antonio is relatively low risk.
