Public Service submits CPCN applications for three wind projects in Colorado

Public Service Company of Colorado is moving forward with plans for three significant wind energy projects after a recent government meeting where the commission approved their applications for certificates of public convenience and necessity (CPCNs). These projects, part of the company's 2021 electric resource plan, aim to enhance the state's clean energy capacity.

The Cheyenne Ridge 2 project will feature a 450-megawatt facility, while the Singing Grass project will have a capacity of 603 megawatts. Both will connect to the Goose Creek substation. Additionally, the Towner project, a 500-megawatt facility, will interconnect at the May Valley substation. Public Service is seeking to increase the cost baselines for these projects due to supply chain issues and geopolitical uncertainties, with adjustments ranging from 5.6% to 23.3%.

The commission's approval is crucial as it allows the company to proceed with construction while addressing concerns raised by the Northern Cheyenne tribe regarding potential impacts on the Sand Creek Massacre National Historic Site. Should the Towner project not receive a CPCN, the company has proposed a backup project, Hart Strong, which would also contribute to the state's renewable energy goals.

In addition to the CPCNs, Public Service is requesting modifications to its electric commodity adjustment tariff to manage transaction costs related to production tax credits. The commission has previously recognized the need for these facilities, and the current discussions will further evaluate the proposed cost increases and project management strategies.

Various stakeholders, including the Colorado Office of the Utility Consumer Advocate and the Colorado Energy Consumers, have intervened in the case, seeking a hearing to examine the proposed cost adjustments and the overall public interest of the projects. The commission is expected to refer the matter to an administrative law judge for further review, ensuring that all concerns are addressed before moving forward.

This decision marks a significant step in Colorado's transition to renewable energy, with the potential to create jobs and support local economies while addressing environmental concerns. The commission's ongoing oversight will be vital in balancing the interests of the utility, consumers, and affected communities as these projects progress.
