Owner: Xcel Energy
Project Summary: RMS Energy was hired to inspect for deficiencies on all reachable components of the Isolated phase bus system, including insulators, seal off bushings, expansions, equipment terminations, grounds, gaskets, access covers, terminal silver plating, conductor and enclosure condition.
About the Client: Cabin Creek is a pumped storage hydroelectric plant located high in the Rocky Mountains at 10,018 feet above sea level near Georgetown, Colo. Water is supplied from two reservoirs totaling almost 2,000 acre-feet, enough for full load operation for both units for four hours. During periods of peak electricity demand on Xcel Energy’s Colorado system, electricity is generated by releasing water from the upper reservoir through a tunnel, which turns the turbine generators. The water is then stored in the lower reservoir. In the early hours of the morning when electricity use by the company’s customers is low, water is pumped back to the upper reservoir. Cabin Creek has the ability to respond to increases in customer demand quicker than any other plant on our system. It is classified as a facility required for reliable operation of the grid.
Inspect for deficiencies all reachable components of the Isolated phase bus system, including but not limited to insulators, seal off bushings, expansions, equipment terminations, grounds, gaskets, access covers, terminal silver plating, conductor and enclosure condition
If present, inspect drains to be free and clear and in working order
