HECO said the power stayed on Wednesday night after warning Oʻahu residents and businesses of possible rolling power outages.
HECO had warned that various neighborhoods could experience rolling power outages starting 10 p.m. Wednesday due to problems at the power plant operated by Kalaeloa Partners. The initial starting time of 6 p.m. was revised later in the afternoon.
However, HECO said it avoided a power shortfall by increasing power generation at the Kahe Power Plant and relying on customer conservation efforts.
If needed, the estimated 30-minute outages would have rotated through the following areas in this order:
- Waipahu, sections of Pearl City, Kunia, ʻEwa Beach
- Waiawa, Crestview, Mililani, Kunia, Waimalu, Upper Kīpapa areas
- Pearl City, Waimalu
- Majority of leeward areas
- Lower Kalihi, sections of Upper Kalihi
- Kakaʻako
- Sections of Kahala
- Sections of Kaimukī and Kapahulu
- Majority of Kaimukī, sections of Kapiʻolani Boulevard and Waikīkī
- University of Hawaiʻi Mānoa campus, Mānoa
- Nuʻuanu and School Street area
HECO said an underground pipe ruptured at the 208-megawatt plant operated by Kalaeloa Partners — the largest independently-owned power plant on Oʻahu. The incident occurred around 1 a.m. Wednesday, causing the plant to suddenly go offline, HECO said. Kalaeloa Partners expects repairs could take three days.
The utility encouraged homes and businesses to conserve energy.
HECO said that because of recent large outages, downtown Honolulu, Chinatown and Hawai‘i Kai would not be included in the outage rotation for Wednesday, July 31.
