HONOLULU, Hawaii — Hawaiian Electric customers across Oahu, Maui County and Hawaii Island are checking power-outage information Thursday, September 24, 2026, as the utility monitors local service interruptions while preparing its electrical system for possible impacts from Tropical Storm Nolo. Hawaiian Electric, commonly known as HECO, maintains separate outage maps for Oahu, Maui County and Hawaii Island. The utility cautions that customer totals and estimated restoration times shown on those maps are approximate and that updates can be delayed when multiple outages occur simultaneously. There is no indication in the latest official information reviewed of a single statewide HECO blackout. Instead, customers should check their individual island outage map because localized interruptions can develop and be restored rapidly. The situation is receiving additional attention because Hawaiian Electric is preparing crews and equipment ahead of Nolo, which is forecast to bring potentially dangerous weather to parts of the state over the coming days. Is Hawaiian Electric Experiencing a Power Outage Today? Localized power outages may occur across Hawaiian Electric’s service territory, but HECO does not publish one static statewide number that should be treated as permanent throughout the day. Instead, the utility directs customers to its live outage maps. Hawaiian Electric provides separate maps for: Oahu Maui County Hawaii Island The company’s official outage pages state that most outages appear on the maps, but customers who lose electricity should still report their specific address so crews know that location is affected. A third-party outage tracker drawing from utility data showed only a small number of HECO customers without service in a late-Wednesday/early-Thursday snapshot rather than a widespread system failure. Because outage totals can change quickly, Hawaiian Electric’s own maps remain the preferred source for current, address-level information. HECO Power Outage Status Service Detail Latest Information Utility Hawaiian Electric Date September 24, 2026 Service Areas Oahu, Maui County and Hawaii Island Statewide HECO Blackout No widespread statewide blackout confirmed Localized Outages Possible; customers should check live island maps Major Weather Concern Tropical Storm Nolo Oahu Outage Line 1-855-304-1212 Maui County Outage Line 1-855-304-8181 Hawaii Island Outage Line 1-855-304-9191 Kauai Service Operated separately by Kauai Island Utility Cooperative Restoration Times Vary by incident and may change Current Status Developing as weather conditions evolve Tropical Storm Nolo Raises Outage Concerns Power reliability is receiving additional attention because Tropical Storm Nolo formed south of Hawaii and is forecast to strengthen. As of late Wednesday night, the storm was approximately 285 miles south of South Point on Hawaii Island and was moving slowly northward. Forecasters said it could strengthen into a hurricane and approach the Big Island Friday and Saturday. The storm could produce very heavy rainfall, flooding and strong winds, particularly on Hawaii Island and Maui. Those conditions can cause power interruptions when trees, branches, debris or damaged infrastructure come into contact with electrical lines. Hawaiian Electric said crews are preparing vehicles, equipment and replacement materials in advance while management schedules personnel so workers can safely respond if outages increase. Hawaiian Electric Prepares Crews for Possible Nolo Outages HECO officials said crews are checking trucks and ensuring they have additional equipment and replacement materials before deteriorating weather reaches the islands. The utility is also reviewing crew schedules to ensure workers receive required rest while maintaining enough personnel for emergency restoration work. Hawaiian Electric has experienced several major storm-related restoration efforts during the 2026 hurricane season. Hurricane Lala damaged significant portions of Hawaii Island’s electrical system in August, at one point leaving tens of thousands of customers without electricity. The utility announced August 31 that repairs to all major systems damaged by Lala had been completed and power had been restored to all customers who could safely be reconnected, aside from limited access and customer-property issues. Hurricane Lowell then caused additional outages on Oahu in September. Hawaiian Electric said approximately 21,000 Oahu customers were without power early September 8 before restoration work substantially reduced that number. Those previous outages are separate from Thursday’s service conditions. Recent Hawaii Kai Outages Draw Attention Power reliability has also been a concern recently in East Oahu. On September 20, approximately 13,750 Hawaiian Electric customers initially lost electricity in areas including Hawaii Kai, Aina Haina, Hahaione, Hawaii Loa Ridge, Kalama Valley, Koko Head, Koko Marina, Niu Valley, Portlock, Wailupe and Waimanalo. Hawaiian Electric said power was restored by approximately 9 p.m. and stated that the outage was not a Public Safety Power Shutoff. The cause remained under investigation at the time. More localized outage alerts have continued to appear in the East Oahu area, reinforcing why customers should rely on the live map instead of assuming that an earlier restoration means every address currently has service. How to Check the HECO Outage Map Hawaiian Electric’s official Safety and Outages portal provides direct access to the company’s island-specific outage maps. For Oahu, customers can view reported outages and estimated restoration information when available. Similar maps are maintained for Maui County and Hawaii Island. HECO warns that during major emergencies: map updates may be delayed; customer totals are approximate; estimated restoration times can change; and some individual outages may not immediately appear. For that reason, customers without power should report their own outage even if a nearby interruption already appears on the map. How to Report a Hawaiian Electric Power Outage Customers can report outages directly to Hawaiian Electric. Oahu: 1-855-304-1212 Maui County: 1-855-304-8181 Hawaii Island: 1-855-304-9191 The outage lines help Hawaiian Electric identify affected locations and dispatch crews. The company’s Storm Center says outage-reporting services are available 24 hours a day, seven days a week. Immediate emergencies involving fire, injury or another threat to life should be reported through 911. Is Kauai Part of the HECO Outage Map? No. One important distinction for people searching for “Hawaii power outage today” is that Hawaiian Electric does not provide electric service on Kauai. Kauai is served by the Kauai Island Utility Cooperative, or KIUC. Hawaiian Electric’s service territory covers Oahu, Hawaii Island and Maui County, including Maui, Molokai and Lanai. HECO’s emergency communications page specifically directs Kauai residents to their own utility provider. Hawaiian Electric has assisted KIUC with restoration efforts following earlier hurricane damage, but Kauai outage numbers should not be counted as HECO customer outages. Could Nolo Cause More Hawaii Power Outages? Yes, additional outages are possible if Nolo produces damaging winds, flooding or falling vegetation. That does not mean widespread outages are certain. The severity will depend on the storm’s eventual track, intensity and effects on individual islands. The National Hurricane Center forecast indicates that Hawaii Island could receive particularly heavy rainfall, with Maui also facing a significant flooding threat. State officials have already announced closures of parks, forest lands and camping areas on Hawaii Island beginning Thursday, with Maui and Molokai closures scheduled to follow Friday because of anticipated storm conditions. Hawaiian Electric is advising customers to prepare for the possibility that power interruptions could last longer than normal if severe weather prevents crews from safely accessing damaged lines. What to Do During a Power Outage Hawaiian Electric recommends keeping emergency supplies ready, particularly during storm season. Customers should have flashlights, batteries, non-perishable food, drinking water, necessary medications and other emergency supplies available. The utility also recommends unplugging unnecessary appliances and sensitive electronics during outages and keeping refrigerators and freezers closed as much as possible. Anyone using a portable generator should operate it outside in a properly ventilated area and follow the manufacturer’s safety instructions. Downed Power Lines Should Be Treated as Energized Storm-related outages can involve fallen trees, damaged poles or downed electrical wires. Hawaiian Electric advises people to stay away from downed power lines and treat them as energized even if the surrounding neighborhood appears to have lost electricity. People should not attempt to move electrical wires or objects touching them. During the Hurricane Lala recovery, Hawaiian Electric advised residents to remain at least 30 feet from downed lines and immediately report dangerous electrical equipment. Customers With Medical Equipment Should Prepare An extended outage can be particularly serious for people who depend on electrically powered medical equipment. Hawaiian Electric advises medically dependent customers without backup electricity to identify an appropriate location where reliable power will be available and to take necessary medications and equipment with them. Customers can also register for Hawaiian Electric emergency outage communications, including notifications related to Public Safety Power Shutoffs. Are Today’s Outages a Public Safety Power Shutoff? There is no broad HECO Public Safety Power Shutoff currently identified in the sources reviewed for this update. A PSPS is a deliberate safety measure in which electricity can be temporarily shut off in designated high-wildfire-risk areas when weather and vegetation conditions create an extreme fire threat. Individual equipment failures, storm damage or other unplanned outages should not automatically be described as a PSPS. For example, Hawaiian Electric specifically said the September 20 Hawaii Kai outage affecting more than 13,000 customers was not a Public Safety Power Shutoff. Final HECO Power Outage Update As of early Thursday, September 24, 2026, there is no confirmed Hawaiian Electric systemwide blackout affecting Oahu, Maui County and Hawaii Island. Localized outages can still occur and change quickly, making HECO’s official outage maps the most useful resource for customers checking their particular community. Hawaiian Electric cautions that map totals and restoration estimates are approximate. Attention is increasingly focused on Tropical Storm Nolo, which could bring heavy rain, flooding and damaging winds to parts of Hawaii beginning Thursday and continuing into the weekend. Hawaiian Electric says crews and equipment are being prepared for potential outages and restoration work. Customers should continue monitoring their island’s HECO outage map as weather conditions develop. Frequently Asked Questions Is HECO experiencing a power outage today?
