The Arizona Corporation Commission at a Nov. 6 meeting approved Arizona Public Service's application for a certificate of environmental compatibility authorizing a new, 1.45-mile, 230-kV transmission line to serve data-center projects underway in the town of Goodyear, west of Phoenix [L-00000D-19-0196-00183].
The line is planned to run from the existing 230-kV Palm Valley-to-Rudd transmission line located about a third of a mile south of the Wildcat and Cyclone data-center sites, two separate but adjacent projects being built by Microsoft and Stream Data Centers, respectively.
Microsoft plans as many as three data-center buildings to be built in phases at the site, according to local media reports. Stream plans 2 million square feet of data-center facilities in Goodyear. Vantage Data Centers is also planning a 50-acre campus in the town, and Compass Data Centers began construction last summer on the first two of eight buildings for a 225-acre campus there, according to APS.
Mike Gardner, representing Microsoft, told commissioners the company serves more than a billion customers worldwide through its cloud servers and needs additional capacity to meet growing demand. He said Microsoft selected Arizona for this data-center site because of its pro-business environment, available land and favorable energy prices. As demand grows, Gardner said, the company anticipates expanding in the area.
