An estimated 65,000 Hawaiian Electric customers on Maui lost power early Tuesday morning. As of 2 p.m., crews had restored power to all customers, HECO said.
The widespread outage started around 2:45 a.m. Power came back for neighborhoods throughout the morning.
Areas impacted included South Maui, West Maui, Central Maui — including areas of Kahului, Wailuku, Waiheʻe and Waiehu — Upcountry and East Maui.
The cause of the outage was a high-voltage short circuit at a substation in Mā‘alaea which triggered generating units to trip offline, HECO said in a statement.
"This is a highly unusual event – the last outage to affect a large number of Maui customers occurred after a lightning storm in 2017 – and the company is looking into the cause of the short circuit," HECO said.
Various Maui County services and traffic signals were also impacted. The following Maui schools closed Tuesday:
West Maui
- King Kamehameha III Elementary
- Princess Nahienaena Elementary
- Lahaina Intermediate
- Lahainaluna High
