  2. HPX Vision Jointly explore opportunities to expand the electric transmission grid in Wyoming, Colorado, New Mexico and Arizona to reliably meet the growing electricity needs by increasing access to renewable and other diverse resources within regional energy resource zones. 2

  3. High-Voltage Transmission from WY – CO – NM - AZ Provide Transmission Path to “Energy Resource Zones” Allow Access to Economic Resources Integrate with Other Projects: Tot 3 Expansion Eastern Plains Transmission Project (EPTP) Northern New Mexico Import (NNMI) SunZia TransWest HPX Project Summary 3
