Current Status:
FERC has approved license amendment for the Ruedi hydroelectric project.
The City of Aspen has received approval from the Federal Energy Regulatory Commission (FERC) for an amendment to the license for the Ruedi hydroelectric power project. The amendment authorizes the installation of a new turbine and generator, allowing the city to install new units that will allow the project to generate up to the 5MW of hydroelectric energy, originally intended and licensed, but which the facility was unable to achieve due to equipment limitations.
Past Engagement:
On February 14,2025, the city of Aspen held a public meeting to inform stakeholders about the proposed amendments to the Ruedi hydroelectric project and to seek comments regarding additional information and study requests. The application to the Federal Energy Regulatory Commission, comment submissions, and a recording of the meeting are available on this webpage. The city of Aspen took comments until April 15, 2025.
Specifically,
Are there other necessary studies that should be performed or information provided
Your understanding of resource issues and your goals and objectives for these resources
Explanation of study requests, including methodology and whether that methodology is a generally accepted practice
Explanation of why the study results or information requested is useful for furthering your resource goals and objectives

Project Overview:
The City of Aspen is proposing to amend its Federal Energy Regulatory Commission (FERC) license for the Ruedi hydroelectric project to install a second turbine and generator within the existing powerhouse located at Ruedi dam. The purpose of the second turbine and equipment improvements is to restore the project to achieve the approved 5 MW of power generation on a more regular basis.
Project Background:
Aspen’s existing FERC license authorizes Aspen to generate 5 MW of hydroelectric energy whenever the Bureau of Reclamation releases water from Ruedi Reservoir to the Fryingpan River. The Bureau of Reclamationreleases water to the river at higher flow levels than it had in the past to provide fish flows downstream. These flow levels are different than what theexisting turbine and generator were designed for, and Aspen is less frequentlyable to produce the authorized capacity of 5 MW.
The new turbine and generator will operate at flow rates outside the range of the existing equipment, allowing the combined facilities to generate the 5 MW of hydroelectric energy. These proposed modifications will entail a small expansion to the existing powerhouse; installation of new electrical equipment; and the addition of a second tailrace (in the same location as the existing tailrace) to release water back to the river from the second generator when it is operating. Prior to seeking FERC’s authorization for these modifications, Aspen issoliciting stakeholder comments on its draft FERC license amendment application.

To me this sounds good, generate more clean energy!
