Building 3 is estimated to be operational. We estimate the operational date by analogy to the time that Building 1 took to go from a foundation to being operational. The power capacity is based on the number of generators reported in an air quality permit application (p.92-93). The dry cooler array is more than double the size of the Building 1 array, which suggests an even larger power capacity than we estimate, but we believe the generator-based estimate is more reliable here.

Building 3 has a partially complete shell, electrical and mechanical equipment. Building 4 foundation is underway.

Building 3 foundation is underway. Building 2 exterior looks totally clean/landscaped.

Building 2 is operational. Based on a Google Earth image showing complete building shell, mechanical equipment and generators, plus cars parked at the front.

Building 2 now has generators in place, but there is still a crane and construction work present.

Building 1, which was first operational in 2021, has increased power capacity by about 75%. This is based on the expansion of the dry cooling array from 4 to 7 columns (seen on Google Earth). Its backup generators also grew from 18 to 33, an 83% increase. Around this time (2023 Q3) the quarterly PUE of the campus is 1.24, down from the initial 1.29 in 2022 Q3. Since no other buildings have been added, these changes indicate an increase in power density, which may entail a new generation of hardware getting installed.

Land clearing begins.
