Hawaii Electric Light Co.reports that about 21,000 customers in various areas of the island experienced a brief power interruption this afternoon due to a sudden loss of generation when a combustion turbine unit at its Keahole Power Plant tripped offline.
Protective devices automatically disconnected some customers temporarily to re-balance the available supply of power generation with the demand for power, stabilizing the grid and maintaining service for the majority of customers. Those affected experienced a temporary power interruption lasting about 10 minutes while backup generators were started.
The unit has since been returned to service. Customers who remain without service may call 969-6666. HELCO also posts outage information on its Twitter account @HIElectricLight with the hashtag #BigIslandOutage.
