Pipeline: active generation and storage requests in the ISO queue, or EIA planned plants where larger (outside the ISOs). Top kV: highest substation voltage. Power price: the state's industrial average. DCs: GPU colocation, mining sites and AI campuses.
What the data shows
The strongest Colorado counties for a large AI load are Weld County (64), Pueblo County (62) and El Paso County (61) on the site score. Colorado sits in utility territory; its ISO queues hold 12 GW of active generation and storage requests, 4.2 GW of them with a signed interconnection agreement, and it has 23 substations at 345 kV and up.
Industrial power averaged 9.6¢/kWh (EIA, July 2026 YTD), against 9.0¢/kWh a year earlier, the 32nd lowest of the 50 states and DC. Colorado has no data center-specific sales tax exemption. We track 1 AI campus and 27 GPU-ready colocation facilities here.

Data center tax exemption in Colorado
No data center-specific sales tax exemption found. HB26-1030, which would have offered 20- to 30-year sales and use tax exemptions for data centers investing $250M, was postponed indefinitely in committee on May 7, 2026.
Recent change: HB26-1030 (data center incentives) died in the House Energy and Environment Committee on May 7, 2026; a similar 2025 bill (SB25-280) also failed.
