Denali National Park & Preserve (AK)
Significant Power Outages, Closures Averted
A major power failure affected numerous buildings in the park headquarters area for 48 hours beginning on Wednesday, May 21st. It occurred as inspectors were testing the condition of the lines. Park crews scrambled to install temporary lines to bypass the failed sections so that facilities and services at headquarters remained available to support activities during the park’s intense visitor season. Over the past four months, 15 percent of the underground electrical distribution system at Denali has failed. Inspections on the failed sections, which are 35 years old, have revealed that the electrical insulation has deteriorated significantly. The contractors hired to inspect and test the system have determined that the problem is systemic and predict that the distribution system will fail completely in the near future unless the power lines are replaced.
