Data center siting snapshot: Laramie County, Wyoming

Line miles are measured from the archived HIFLD Transmission Lines layer inside the Census county boundary. Mapped lines are not available capacity.

What the public record shows

The archived HIFLD map indicates approximately 323.9 miles of 230 kV-and-above transmission line within Laramie County, comprising 95.0 miles at 345 kV and 228.9 miles at 230 kV ^[1]. An additional 142.8 miles of 115–161 kV line are mapped in the area ^[2]. Western Area Power Administration, Tri-State G&T Association, and High West Energy hold the most mapped 115 kV+ line miles ^[3]. Two named line endpoints touching 230 kV+ lines are located inside the county ^[4]. Retail electric utilities with mapped service territories covering part of the county include Western Area Power Administration, High West Energy, Black Hills Power, Cheyenne Light Fuel & Power, and Wheatland Rural Electric Association ^[5].

As of 2026-11-09, records show no county- or city-level data center moratorium or ordinance for Laramie County ^[6]. State-level legislation includes HB0064 (2013), which extended eligibility for co-located data center structures ^[7]. HB0117 (2011) expanded the data processing services center exemption framework ^[8]. HB0067 (2010) created sales and use tax exemptions for qualifying data processing centers ^[9]. HB0155 (2026), which would have created reporting requirements and possible fees for exemption claims, failed ^[10]. HB0088 (2021), which would have repealed data center sales and use tax exemptions, also failed ^[11].
