The city of Aspen’s Ruedi Hydroelectric Facility is anticipated to lose hydroelectric power in early August due to current U.S. Bureau of Reclamation reservoir forecasts and operating conditions. The updated reservoir data indicate that the timing has shifted later than previously anticipated, which the city’s Utilities Resource & Portfolio Manager Joshua Mattson confirmed to The Aspen Times. According to him, earlier planning projections that were provided by the U.S. Bureau of Reclamation indicated the reservoir could drop below the hydroelectric power pool threshold in mid- to late July.
“Updated reservoir elevations, inflow and outflow conditions, and U.S. Bureau of Reclamation operational forecasts now indicate the threshold is more likely to be reached in early to mid-August,” Mattson wrote in an email. “The shift reflects actual reservoir conditions improving relative to earlier projections and ongoing changes in reservoir operations and water demand. This remains a forecast and will continue to be evaluated as conditions evolve.”
The hydroelectric power pool represents the minimum reservoir elevation that is required in order to safely operate the hydroelectric turbine and associated equipment, according to an information update provided to Aspen City Council on Monday. When reservoir levels fall below this threshold, city staff will consequently take the Ruedi Hydroelectric Facility offline in order to protect equipment.
“This outage is not related to dam safety; rather, it is the result of hydrologic limitations associated with drought conditions,” the information update states. “The facility is expected to remain offline until reservoir levels recover above the minimum power pool elevation, which is anticipated to occur in spring 2027 as seasonal inflows increase.”
