Pathways to Developing Transmission in Colorado and the Role of the Colorado Electric Transmission Authority

The document outlines the complex regulatory and permitting landscape for transmission in Colorado, contrasting the processes for public utilities and independent developers. It highlights the role of the Colorado Electric Transmission Authority (CETA) in addressing transmission gaps identified in a 2024 study, specifically through its ability to issue revenue bonds, exercise eminent domain, and facilitate public-private partnerships to advance complex projects that traditional utility planning might overlook.

• A 2024 Transmission Capacity Expansion Study conducted by CETA concluded that Colorado's current transmission planning may be insufficient to meet generation needs and load growth forecasts. The study identified critical transmission gaps in Northeast Colorado, San Luis Valley, and Southeast/South Central Colorado, noting that 550 miles of new lines are essential over a 20-year period, though 80% of needs could be met by upgrading existing infrastructure.
• Public utilities in Colorado must follow a regulated planning process overseen by the Colorado Public Utilities Commission (PUC), which includes submitting ten-year transmission plans every two years and obtaining a Certificate of Public Convenience and Necessity (CPCN) for significant projects. In contrast, independent transmission developers generally operate outside these formal regulatory cycles and may not require a CPCN unless they are classified as public utilities.
• Transmission permitting in Colorado is a fragmented process involving multiple jurisdictions. Local county and municipal governments hold primary permitting authority and may use "1041 powers" to regulate activities of state interest. Projects crossing federal lands must undergo environmental reviews under the National Environmental Policy Act (NEPA), and developers must consult with federally recognized Tribes if projects affect Tribal interests.
• CETA can reduce financial risks for transmission projects, particularly for independent developers who lack the secured revenue streams of regulated utilities. CETA is authorized to issue revenue bonds with terms up to 30 years that are exempt from state taxes, providing lower-cost capital than conventional commercial debt.
• CETA possesses the authority to use eminent domain as a last resort to acquire rights-of-way, which helps mitigate the risk of project delays caused by unresolved land acquisition issues. This authority is available to CETA regardless of whether a private developer has obtained a CPCN.
• CETA is positioned to advance complex, high-impact projects that face significant hurdles. A project shortlist includes the Craig-Coyote line, the Poncha-Midway line, the Montrose-Curecanti-Poncha line, the Montrose-Maverick-Lost Canyon-Shiprock line, the San Luis Valley Alternatives, and the Ault-Archer and Ault-Terry Ranch Reconductors.
