Two carriers on the Interstate 90 corridor
Range / Advanced Communications Technology and Visionary Broadband both operate along Interstate 90, three and a half miles north of the Energy Park.
Range / Advanced Communications Technology (AS30110) operates carrier-neutral facilities in Gillette, Buffalo and Sheridan, the three Interstate 90 towns bracketing the site, plus Casper, Douglas, Cheyenne and Colstrip, Montana.
Visionary Broadband, headquartered in Gillette, operates two 100G rings in a figure-eight: Gillette to Billings, then Casper, Cheyenne, Denver and back to Gillette. That geometry gives east and south route diversity out of the corridor.
Pronghorn also owns and operates 10.4 miles of fiber on the position, in service today for field telemetry and control. It is not a long-haul route. What it establishes is that fiber construction inside the field is routine work under existing easements.
| Corridor distance from site | 3.5 mi |
| Carriers on the corridor | 2 |
| Carrier-neutral facilities within 70 mi | 3 |
| Operator fiber on the position | 10.4 mi |
| Route diversity | East (Billings) and south (Denver) |
The item that needs a build
Wyoming long-haul routes commonly top out near 144 strands. Hyperscale campuses are built against 864 to 1,728. Closing that gap takes a purpose-built lateral from the Interstate 90 corridor into the site and a high-strand-count build along the corridor itself.
This is a construction and funding question, and the mechanism already exists. Wyoming’s statutory Broadband Development Program (W.S. §9-12-1501 et seq.) and the Wyoming Broadband Office are the route for a public-private build. The Connect Wyoming grant rounds run through the same office, though their current funding is federal and time-limited rather than a standing state appropriation.
Pronghorn will engage the Broadband Office and the carriers jointly on a build sized to a counterparty’s requirement. That conversation needs a strand count, a diversity requirement and a latency target.
- Latency to Denver and Salt Lake is competitive for training and batch inference
- Interactive, latency-critical edge workloads are a poorer fit for this location
Three inputs produce a build plan
Strand count
The requirement at full build and at first energization. These are usually different numbers, and the difference drives the funding case.
Diversity
How many physically separate paths are required, and whether the second path has to leave the state in a different direction. The figure-eight ring geometry helps here.
Latency target
To which peering points. That decides whether the answer is a lateral to the corridor, or a lateral plus a new long-haul segment.
Carrier facility locations and autonomous system numbers are from PeeringDB. The figure-eight ring architecture and 100G capacity are as publicly reported by the operator in 2023 and should be re-confirmed against a current network diagram before being relied on. No public route-level geometry exists for either carrier, so the corridor drawn on the maps is an indicative alignment along Interstate 90 rather than a surveyed cable route.
A load profile is enough to begin.
Send target megawatts at first energization, a ramp schedule and a cooling approach. Pronghorn returns a generation block plan, a field development sequence, a water allocation and a term sheet across power, land and fuel. Capital and structure inquiries reach the same team.
