Wyoming Intertie is an approximately 106-mile, up-to-1,800 MW, high-voltage transmission line connecting the Eastern and Western Interconnection grids. The line extends through Carbon, Albany, and Platte Counties in Wyoming, with endpoints in Carbon County and Platte County.
By enabling power flow between the eastern and western power grids, Wyoming Intertie will improve the overall reliability and resiliency of the power grid. Wyoming Intertie will carry all sources of electrical power generation and transport power in both directions based on real-time power demand. This will allow Wyoming electricity generators to access new markets across the Eastern and Western Interconnections.
Wyoming Intertie is in the planning and development phase. Prior to initiating regulatory filings, Wyoming Intertie collaborates with stakeholders and landowners to determine a preliminary route. Construction will commence after Wyoming Intertie secures regulatory approvals. Wyoming Intertie could be operational in the early 2030s.
Approximately 106 miles, Wyoming Intertie will stretch across Carbon, Albany, and Platte Counties and move up to 1,800 MW of power between the eastern and western grids. Wyoming Intertie will connect substations near Medicine Bow and Wheatland.
By linking the Eastern and Western Interconnections, Wyoming Intertie will create a wide range of benefits:
By increasing the transferability of power between both grids, Wyoming Intertie will reduce the risk of outages or blackouts during extreme weather events.
Consumers will benefit from new access to low-cost energy generated in different regions. By linking geographically and meteorologically diverse regions with complementary power generation profiles (i.e., those that generate power at different times of day), Wyoming Intertie will allow both sides of the line to efficiently import at optimal (low-cost) times—which reduces the production costs of traditional power generators.
Wyoming Intertie is open to all forms of power generation. Wyoming’s power producers will gain a new outlet to export excess power during periods of low demand.
The project represents an estimated $2 billion investment in Wyoming and will serve as a long-term asset for the state. Communities and the state will benefit from additional property tax revenue, temporary and permanent jobs, and direct community investments.
Building strong and lasting relationships with landowners and communities is how Wyoming Intertie approaches development. Wyoming Intertie commits to a collaborative development process, and to conduct easement negotiations in a manner that is respectful of private property rights.
The Eastern Interconnection, Western Interconnection, and the Electric Reliability Council of Texas (ERCOT) comprise the national power grid. These three parts operate largely independent of one another with insufficient connections between them. With energy demand increasing, the fractured grid is a bottleneck to ensuring energy reliability and security nationwide.
