(Honolulu) This is an update to the island-wide power outage on Oahu that began yesterday evening when most customers lost power starting at about 6:30 p.m. Hawaiian Electric Company has restarted several generating units at the Waiau and Kahe Power Plants and one unit at its Honolulu Power Plant. Additionally, a unit at an independent power producer, Kalaeloa Energy Partners, is currently online.
Approximately 156,000 customers, primarily in the following areas, have been restored as of 7:05 a.m.: Major portions of Leeward and Central Oahu, including Pearl City, Aiea, Waianae, Nanakuli, Makaha, Waipahu, Kapolei, Makakilo, Ewa Beach, Kunia and Wahiawa. In addition, portions of other areas have been restored including parts of Waiakamilo, Waialua, Kailua, Waimanalo, Makiki, Kapiolani, Aina Haina and portions of Waikiki. Power has been restored to the Honolulu International Airport and all major hospitals.
Hawaiian Electric asks customers who do have power to help by practicing energy conservation while the restoration process continues. This will help maintain stability on the grid.
Restoration started on the west side of the island. Those who live near the leeward power plants were generally restored first because their electrical load can be added to the grid faster once power generation is started up, more quickly reestablishing the stabilizing balance between power supply and demand. Once this part of the grid was re-energized and as power plant generators were restarted to produce more power, Hawaiian Electric has been able to continue the process of restoring power to other customers.
The restoration progress is moving gradually from the West side of the island to the East. In addition, pockets of customers in other areas may be restored as well, depending on the configuration of the transmission system serving their area.
“We appreciate our customers’ continued patience,” said Lynne Unemori, Hawaiian Electric Vice President of Corporate Relations. “We do ask for their understanding that full restoration may take many more hours and they should plan accordingly. Restoring power safely is our first priority. We are working around the clock until all customers have power.”
