Energy Corridor Basics

Basic information on energy corridors.

What Is an Energy Corridor?

For purposes of preparing the West-wide Energy Corridor Programmatic EIS, an energy corridor is defined as a parcel of land (often linear in character) that has been identified through the land use planning process as being a preferred location for existing and future utility rights-of-way, and that is suitable to accommodate one or more rights-of-way which are similar, identical or compatible.

What Are the Components of an Energy Corridor?

Energy corridors may accommodate multiple pipelines (such as for oil, gas, or hydrogen), electricity transmission lines, and related infrastructure, such as access and maintenance roads, compressors, pumping stations, and other structures. Photographs of equipment and facilities found in energy corridors, and associated construction activities are available on the Photos page.

More detailed information on energy corridor components is also available in the following technical reports:

What Benefits Will Energy Corridor Designation Bring?

Expected benefits of energy corridor designation under the Energy Corridor PEIS include the following:

  • Streamlining and expediting the processing of energy-related permits and projects;
  • Providing applicants for individual rights-of-way within designated corridors with a clear set of actions required by each of the Agencies to implement projects in designated corridors;
  • Reducing duplicative assessment of generic environmental impacts by focusing further impact assessment on site-specific (on-the-ground) environmental studies to determine route suitability and appropriate mitigation;
  • Ensuring needed inter-agency coordination as part of the application process; and
  • Encouraging new and innovative technologies to increase corridor capacity.
