Weighing Colorado against another state or a Canadian province with a different rate and interconnection picture entirely? Run both sides of the comparison through our licensed AI data center cost configurator — it applies each jurisdiction's actual power rate, tax treatment and large-load tariff rules to the same seven build configurations.
Every figure above comes from the same power-cost and tariff dataset behind the SCR AI Build Configurator — a licensed, embeddable widget that models seven data center build configurations against all nine Canadian provinces and all 50 US states plus DC, returning capital expenditure by line item, energy cost, revenue by commercial structure, EBITDA and payback.
| Licence | Price (CAD) | Who it suits |
|---|---|---|
| Standard | $4,000 / domain / year | Advisors who need three lease-model configurations and a clipboard summary |
| Pro | $10,000 / domain / year | Consultants who send CSV deliverables to clients and want all seven configurations |
| Enterprise | From $25,000 / year, up to 3 domains | Developers and EPC firms who want the model on their own cost basis with attribution removed |
Not ready for an annual licence? A one-time Site Screening Report ($950, one site) runs the same model for a single build without embedding anything.

No. Xcel Energy's Proposed 50 MW Large-Load Tariff sits above Public Service Company of Colorado (Xcel Energy)'s standard commercial and industrial rate schedules and applies specifically to customers that meet or exceed the large-load threshold described above. Smaller commercial and industrial loads continue to be billed under existing rate schedules.
The SCR AI Build Configurator applies Colorado's power cost, tax treatment and large-load tariff rules alongside all other US states and Canadian provinces, so a Colorado scenario can be compared line-by-line against any alternative site.
