Data center siting snapshot: Clark County, Nevada

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 displays approximately 2013.0 miles of 230 kV-and-above transmission line within Clark County, Nevada, including 715.3 miles at 500 kV or more ^[1]. This high-voltage infrastructure is accompanied by about 358.2 miles of 115–161 kV line ^[2]. The owners of record holding the most mapped 115 kV+ line miles are Nevada Power, Intermountain Power Agency, and Los Angeles Department of Water and Power ^[3]. Additionally, 24 named line endpoints touching 230 kV+ lines are mapped inside the county ^[4]. Retail electric utilities with mapped service territories covering part of the county include Southern California Edison, Colorado River Commission of Nevada, Western Area Power Administration, Nevada Power, and Overton Power District No 5 ^[5].

At the local level, a November 3, 2026 ballot measure in Boulder City was enacted, rejecting the allowance of data centers in the Eldorado Valley Transfer Area ^[6]. In Clark County, a moratorium push failed on July 8, 2026, when commissioners took no formal action and directed staff to research uniform standards ^[7]. State legislation enacted in 2025 includes AB458, which excludes certain data center equipment from public utility definitions ^[8], and SB69, which requires defray agreements and local notice steps for projects in economic diversification districts ^[9]. AB509 was also enacted, addressing broadband and right-of-way issues with data center language ^[10]. Conversely, AB226 was vetoed, while SB403 and AB77 failed to pass ^[11][12][13].
