Transmission & Pipeline

As one the second-largest net energy suppliers in the United States, Wyoming relies heavily on a network of transmission and pipeline to distribute the energy it makes to consumers across the nation.

Pipelines

Wyoming has approximately 100 companies that operate over 25,000 miles of pipelines, excluding all gathering systems and inactive or abandoned pipelines. These pipelines can be found throughout all 23 counties of Wyoming and transport various substances, including natural gas and petroleum products.

Notably, Wyoming participates in the Western Interstate Energy Board, an organization of eleven states and two Canadian Provinces that collaborate on topics including transmission for the betterment of regional operations.

Transmission Efforts in Wyoming and Beyond

PacifiCorp's Energy Gateway Transmission Expansion Program

PacifiCorp plans to build 2,300 miles of transmission lines for $8 billion. The Energy Gateway transmission lines aim to address customer load growth, improve system reliability, reduce transmission constraints, provide access to diverse generation resources, and enhance electricity flow across PacifiCorp’s six-state service area.

Wyoming-Specific Transmission Lines

The 140-mile, 500-kV transmission line between the Aeolus substation near Medicine Bow in Wyoming and the Jim Bridger generating facility was placed in service in 2020. The high-voltage transmission line spanning 59 miles between the Windstar substation close to Glenrock, Wyoming, and the Aeolus substation will be operational by 2024.

Black Hill’s Energy Ready Wyoming Project

Black Hills Energy’s Ready Wyoming project is a 260-mile transmission line expansion project in southeastern Wyoming. The project will improve the resilience of the larger electric system and support economic growth and increasing energy demands in the region.

The Joint Federal-State Task Force on Electric Transmission

To accommodate an increasing demand for electricity, new transmission infrastructure must be efficiently developed. Federal and state regulators must address issues such as planning and financing, and cooperation between the federal and state levels is needed. The National Association of Regulatory Utility Commissioners and the Federal Energy Regulatory Commission have formed a Task Force to collaborate on electric transmission-related issues to accomplish this goal.
