- Power rate
- The single biggest running cost. Modelled rates run from US$0.065/kWh (Louisiana, New Mexico) to US$0.38 (Hawaii).
- Grid queue
- Months to energise: 24 in North Dakota, 48 in Virginia, California and Hawaii.
- Construction cost factor
- 0.86× in Arkansas and Mississippi to 1.30× in Hawaii.
- Sales tax on equipment
- 30 states offer a data center exemption; 7 have paused theirs; 10 have none; 4 have no sales tax.
- Large-load tariffs
