Reported facts

Structured facts sourced from citations already on this record. Each fact traces to a source in the References section below.

Operator
xAI
Primary workload
Grok training expansion of the Memphis-area Colossus complex
Announced capacity
~1.2 GW; combined with Colossus 1 targets ~2 GW
Lifecycle
Partially energized (2026)
On-site gas turbines
46 turbines (~495 MW) reported operating without air permits; 41 additional turbines permitted March 2026
Cooling water source
Drinking water, ~1.3M gallons/day early 2026 (site sits too far from wastewater plant)
Planned wastewater treatment
~$80M plant to reuse ~13M gallons/day of wastewater
State investment claim
Reported multi-billion; described as largest private-sector investment in Mississippi history
Regulatory scrutiny
SELC and state regulators flagged unpermitted gas turbines operating on-site
GPU mix + Q4 GB300 ramp (Musk-stated Sep 2026)
Musk-stated (company-stated): Colossus 2 = 110k GB200 + 440k GB300, with another 220k GB300 fully operational the following week, another 220k in November, and maybe another 220k GB300 by late December. Cap: founder X ramp plan; not an independent energization confirmation
Tesla Megapacks 3.3 GWh (company-stated Sep 2026)
Company-stated (company-stated; browser-confirmed Sep 25 2026): Colossus II grid-connected battery pack will provide 3.3 GWh, described as enough to power Memphis for about two hours and as America's largest grid-connected battery pack. Cap: SpaceX Mid-South primary. Sawyer Merritt separately paraphrased these as Tesla Megapacks; that Megapack/Tesla brand wording is not on the SpaceX Mid-South page and is recorded only as a secondary paraphrase, not as company-stated
Regional investment / jobs / tax (company-stated Sep 2026)
Company-stated (company-stated; Sawyer extract Sep 25 2026): since joining the community in 2024, SpaceXAI is investing more than $90 billion in the region; estimated 2026 tax revenue $60M+; 7,500 local jobs supported. Cap: company community page; independent economic-impact audit not reviewed
Clean water recycling plant $360M (company-stated Sep 2026)
Company-stated (company-stated; Sawyer extract Sep 25 2026): SpaceXAI is investing $360 million at no cost to the city in a clean water recycling plant designed to process up to 10 million gallons of wastewater a day and offset ~3.64 billion gallons a year from the Memphis Aquifer. NOTE: existing DC fact 'Planned wastewater treatment' still lists a prior ~$80M / ~13M gallons/day figure from earlier reporting; this $360M claim is a newer dated company-stated update, not a silent overwrite of the older reported figure. Cap: company Mid-South page; plant status and final capacity not independently verified here
Memphis substations $35M + $20M (company-stated Sep 2026)
Company-stated (company-stated; Sawyer extract Sep 25 2026): in Memphis, SpaceXAI is investing $35 million in a 150 MW substation to support MLGW and another $20 million in a second substation, both at no cost to MLGW or homeowners. Cap: company community page claim
Temporary turbines remove-by July 2027 (company-stated Sep 2026)
Company-stated (company-stated; Sawyer extract Sep 25 2026): under an agreed order with the Mississippi Department of Environmental Quality, all remaining temporary turbines must be removed by July 2027; SpaceXAI says it is already taking units offline and expects to complete removal well ahead of that deadline. Cap: company Mid-South page summarizing the DEQ agreed order; DEQ primary order text not attached this pass
Campus scale (Mid-South company-stated Sep 2026)
Company-stated (company-stated; browser-confirmed Sep 25 2026): campus described as over 2.5 million feet, millions of GPUs, and over two gigawatts of compute. Cap: SpaceX Mid-South community page campus framing; distinct from Musk-stated GPU mix/ramp facts
GPUs planned 1M+ (Mid-South company-stated Sep 2026)
Company-stated (company-stated; browser-confirmed Sep 25 2026): Colossus II page figure lists GPUs planned: 1M+. Cap: SpaceX Mid-South page figure; distinct from Musk-stated Colossus 2 mix + Q4 GB300 ramp detail already on this record

Water
Sits too far from the wastewater plant and draws millions of gallons/day of drinking water (about 1.3M gal/day as of early 2026); xAI has announced an ~$80M treatment plant to reuse ~13M gal/day of wastewater. Powered by on-site natural gas turbines.
