Total facility power (MW) - based on satellite + cooling157
Calculated from chiller model, 1.25 cooling overhead, 1.4 PUE
5
Total facility power (MW) - based on identified chiller158
Calculated from chiller spec, 1.15 cooling overhead, 1.35 PUE
6
Total facility power (MW) - based on GPU quantity147
Calculated from GPU parameters
7
Total facility power (MW) - based on turbines180
Title V permit application specifies 10 natural gas turbine generators, with a total of 5 * 38 MW + 5 * 34.1 MW = 360.5 MW between them. The permit pertains to the first two buildings on the site, and we assume this capacity is split equally.
8
Total facility power (MW) - based on reported IT power144
Report by Crusoe (who manage the construction of the data center) said 206 MW energized by 2025, most likely implying 103 MW IT power https://cdn.prod.website-files.com/6855c1aa175582ee23e0aa19/68710273a71bb7c11049ba28_Crusoe_Impact_Report_2024.pdf#page=19
