While there are many challenges, siting and permitting concerns may be the greatest hurdle facing further growth in the transmission system. A growing understanding exists that Colorado’s permitting system may need to be more streamlined and better coordinated. Transmission siting and permitting must balance many interests, including concerns of property owners, environmental constraints, and local governments. These types of concerns must be addressed early in the development process in order to mitigate the chance of a costly delay later in the process. Colorado has already experienced protracted litigation which has stymied expansion of the state’s high-voltage transmission infrastructure and delayed transformation of the electricity sector. To address these issues, the Colorado State Legislature passed SB11-045, which established a task force to produce a report with recommendations regarding transmission siting and permitting. The report is available on the Colorado PUC website.
