Power was restored on Kauai Thursday after an island-wide outage.

The Kauai Island Utility Cooperative said its second largest generator went offline when a fuel valve failed. Power was restored to all customers within two hours.

The John Brown Gas Turbine (GT-2) generator at the Port Allen Generating Station, which generates 22 megawatts of electricity, shut down at 9:53 a.m. Other generators, unable to cover the system load with the loss of GT-2, then tripped off and circuits on the utility’s grid shut down until additional power generation could be brought online, the cooperative said.

The outage affected all of the cooperative’s 30,000 customers.

KIUC restored approximately half its customers at 10:40 a.m., and by 11:20 a.m., 85 percent of power had been restored. Power was fully restored at 11:51 a.m.

Repairs on the generator are being made and the cause of the fuel valve failure is being assessed.

A Kauai County spokesperson said the emergency dispatch center briefly switched to a backup generator but has since regained power and is operating as normal. The district manager’s office at Lihue Airport also confirmed power had been restored.
