Three Corners Connector is an approximately 300-mile, 525 kilovolt high voltage direct current (HVDC) transmission line connecting the existing electric systems near Pueblo, Colorado, and the Oklahoma Panhandle, providing a valuable link between the U.S. eastern and western electric grids. Three Corners Connector will be open to all sources of electrical power generation and will be able to transport power in either direction along the line.
Three Corners Connector is in the planning and development phase. We identified a preliminary corridor for the proposed HVDC transmission line and continue to gather input from stakeholders as we further evaluate the potential location for the line. Using that input, we will finalize our route analysis and initiate regulatory filings, with final approvals expected in 2025. Construction will commence after the project secures land rights and obtains the necessary regulatory approvals. Three Corners Connector could be operational as early as 2028.
The ultimate route will be determined through a process that includes resource data evaluation, a suitability analysis, and landowner feedback and is currently anticipated to be approximately 300 miles long, extending from an existing substation in Pueblo, Colorado, to a proposed substation near Guymon, Oklahoma. Converter stations will be constructed near each endpoint to convert between AC and DC energy, allowing for more efficient and reliable transmission. The route is still being developed and will not be finalized until input has been received from landowners, communities, and local, state and federal government officials.
Our relationship with landowners and communities is at the core of everything we do. We believe that building strong and lasting relationships is key to the success of Three Corners Connector. We are committed to developing the project using a collaborative process and will conduct easement negotiations in a manner that is fair to landowners and respectful of their private property rights.
Three Corners Connector is currently in the planning and development phase. We identified a preliminary corridor for the proposed HVDC transmission line and continue to gather input from stakeholders as we further evaluate the potential location for the line. We have also begun meeting with key stakeholders to introduce the project and gather input, which we will use to finalize our route analysis and initiate regulatory filings.
