About Colorado’s Power Pathway:
Colorado’s Power Pathway is a proposed $1.7 to $2 billion investment to improve the electric grid and enable future renewable energy interconnections around the state. Colorado’s Power Pathway includes approximately 560 to 650 miles of new 345-kilovolt electric transmission line and several new and expanded substations. If approved, segments of Colorado’s Power Pathway could be operating as early as 2025. It will increase electric reliability, connect new energy resources in eastern Colorado, boost the regional economy and create jobs during construction.
