At a glance

Colorado has 1,214 electric substation records in the HIFLD dataset, 400 of them with a station name (the other 814 are unnamed tap points, risers and line ends). 20 named substations operate at 345 kV or above. The highest recorded voltage is 345 kV and the median is 115 kV.

How is Colorado's substation network split by voltage?

By maximum voltage, the named substations break down as 20 at 345–499 kV; 128 at 230–344 kV; 206 at 115–229 kV; 38 at 69–114 kV; 3 below 69 kV; 5 withvoltage not recorded. 5% of Colorado's named substations operate at 345 kV or above, against 8% across all 16,654 named US substations. The state median of 115 kV is level with the national median of 115 kV.

How does Colorado compare with other states?

Colorado ranks 12th of 50 states and DC by number of named substations and 24th by named substations at 345 kV or above. It also has 3,428 scored datacenter candidate sites with an average DC Readiness score of 50.6 (national average 53), and an average power sub-score of 37.5 against 37.4 nationally. Most of those sites (2,039) are in the SPP market.
