Why ʻĀina Haina Loses Power Along With the Rest of East Honolulu

At about 8:08 p.m. on Sunday, September 20, 2026, the lights went out across the east end of Honolulu at once. Hawaii News Now reported that the outage first affected 13,750 Hawaiian Electric customers in ʻĀina Haina, Hahaione, Hawaiʻi Kai, Hawaiʻi Loa Ridge, Kalama Valley, Kamiloiki, Koko Head, Koko Marina, Niu Valley, Portlock, Wailupe and Waimānalo. Power came back by 9 p.m. The utility noted it was not a Public Safety Power Shutoff. KHON reported blackouts around 8 p.m. and again around 10 p.m. that evening. At the time, Hawaiian Electric said the cause was under investigation.

That list of a dozen place names is the key to understanding ʻĀina Haina's power. The ridge homes on Hawaiʻi Loa, the valley streets off Wailupe and the beachfront lots near Kalanianaʻole Highway lost power at the same moment. That tells you the problem started upstream of all of them. For a buyer weighing ʻĀina Haina against Kaimukī, Kāhala or Hawaiʻi Kai, electric reliability belongs to the whole region and not to any single property. No choice of street within ʻĀina Haina opts a home out of it.

The Power Comes Over the Mountain

East Honolulu does not draw its electricity straight from town. In a May 2024 release, Hawaiian Electric explained that the area relies on power lines that bring electricity from Windward Oʻahu. Those lines run along the base of the Koʻolau range near Waimānalo before crossing into East Honolulu. Helicopter inspections that year found the corridors overgrown with albizia trees, and one fallen albizia had already knocked out power to parts of Hawaiʻi Kai. At the time, the utility said it spends about $12 million a year on vegetation management on Oʻahu.

Two years later, the explanation was largely unchanged. Honolulu Civil Beat reported on September 30, 2026, that company executives told a September town hall the same thing. Oʻahu's high-voltage backbone has to cross the steep, heavily forested Koʻolau, which leaves miles of line exposed to falling trees and limbs. Those failures can set off chain reactions of outages. Hawaiian Electric also told Civil Beat that the grid's foundation dates to the 1940s. That is decades before Henry J. Kaiser began building Hawaiʻi Kai in the 1960s, and long before the area grew past 50,000 residents.

"If we were designing this today, we would not design it this way."

One Outage, Hundreds of Households

Civil Beat compared PowerOutage.us data for two parts of Honolulu over the two weeks before its September 30, 2026 article. The figures are a one-mile radius around two points. They are not Hawaiian Electric's own counts.

The number of outages differs by a little more than two to one. The reach of each outage differs by a factor of about sixty. In Kaimukī, a typical outage affects a handful of customers, which looks like a local equipment problem. Near Hawaiʻi Kai, a typical outage affects hundreds, which is what a failure upstream of whole neighborhoods looks like. The September 20 list shows that ʻĀina Haina, Wailupe and Hawaiʻi Loa Ridge sit inside that same upstream footprint.

One distinction matters for comparing homes inside East Honolulu. Hawaiian Electric cited a second problem specific to Hawaiʻi Kai, where aging underground distribution lines are vulnerable to water damage. At the Hawaiʻi Kai Neighborhood Board's July 2026 meeting, Council Chair Tommy Waters relayed the utility's view. It linked recurring flickering and outages in Hahaione Valley and Portlock to deteriorating insulation on underground lines that lack protective conduits. So an ʻĀina Haina home shares the transmission exposure with Hawaiʻi Kai, while the underground-cable issue was attributed to specific Hawaiʻi Kai areas.

Every Fix Comes With a Trade-Off

The September 23, 2026 town hall at Niu Valley Middle School was hosted by Sen. Stanley Chang, Rep. Mark Hashem and Council Chair Waters. KHON reported that it brought legislators and Hawaiian Electric representatives together. Civil Beat described a standing-room-only crowd of nearly 200. Kelly acknowledged the record directly. "I'm sorry we haven't done better," he said, according to Civil Beat.

The structural options he described each come with a cost, according to Civil Beat:

• Overhead distribution lines on poles along Kalanianaʻole Highway. These could reduce problems from aging underground conduits but could raise costs. Kelly also asked how many people would want to see power lines above the highway.
• A new transmission route. Kelly pointed to an earlier plan to run lines over Waʻahila Ridge that was defeated by community opposition.
• Higher rates. Every option was framed against a state that already pays the highest electric rates in the nation.

Hawaiian Electric's chief operations officer, Jim Alberts, put the bind this way, as reported by Civil Beat: "It's a challenge when we put a plan together and we have community meetings and everyone opposes it." KHON reported discussion at the meeting of hardening the transmission lines over the Koʻolau and building a new connection to generation from town. KHON also reported the near-term work Hawaiian Electric described: more tree trimming, equipment replacement, and helicopter work to replace identified poles. That work requires coordination with landowners, including the State, whose land the lines cross. Several days after the meeting, Kelly told Civil Beat the utility was establishing an advisory group of East Honolulu residents.

Sen. Chang set the timeline expectation in the same Civil Beat report. "East Honolulu's electrical grid went from one of the best to one of the worst in the state in just a few years," he said, adding that "any true solutions will take years to complete." Anyone buying in ʻĀina Haina this winter is buying into the grid as it stands today. The structural fixes are still a matter of trade-offs and public process.

On the regulatory side, the nonprofit Life of the Land, led by Henry Curtis, has asked the Hawaiʻi Public Utilities Commission to require more detailed outage information as part of its grid-planning proceeding. The state Office of Consumer Advocacy backs that request.

What Reaches the House Besides the Lights

An outage in ʻĀina Haina affects more than the lights. At the Kuliʻouʻou–Kalani Iki Neighborhood Board's October 7, 2026 meeting, a Board of Water Supply representative explained that the utility has limited ability to pump water from wells to reservoirs during outages. He asked residents to limit water use to essential needs and to keep conserving after power returns so the pumps can refill the reservoirs. For a household, then, an outage can mean asking for water conservation as well as resetting clocks.

The bill is also changing. Hawaiian Electric's rate request is before the Public Utilities Commission in Docket No. 2026-0162. The request for Oʻahu is about $112.2 million in additional annual revenue, or 4.9%. It would phase in starting January 1, 2027, with a second step on January 1, 2028. The companies estimate a typical Oʻahu residential bill would rise by about $11 a month after both phases. The PUC's notice, last updated October 21, 2026, states that no decision has been made. That increase would apply across Oʻahu. So an ʻĀina Haina owner would pay the same proposed rate as a Kaimukī owner while sitting on a feed where each outage reaches far more households.

Questions to Raise Before Writing an Offer

A listing description won't cover any of this, and a home inspection looks at the house, not the lines feeding it. These questions bring the regional issue down to the specific property:

1. How many outages has the home had since mid-August 2026, and how long did the longest one last?
2. Did the home lose power on the night of September 20, 2026, and how quickly did it come back?
3. Does the property have backup power or a solar system with battery storage, and how did it perform during recent outages?
4. Has the home had any water-pressure issues during or right after an outage?
5. For a condominium or townhome, has the association discussed the recent outages and their effect on shared systems such as pumps, gates or elevators?

Some answers will come from the seller, and some from the seller's own utility and association records.

The Kuliʻouʻou–Kalani Iki Neighborhood Board meets the first Wednesday of each month at 6:30 p.m. at ʻĀina Haina Public Library, according to the board's page on honolulu.gov. At its October meeting, members discussed drafting a resolution on Hawaiian Electric that builds on one the Hawaiʻi Kai Neighborhood Board was preparing. Council Chair Waters suggested battery storage in each valley, a redundant transmission line along Kalanianaʻole Highway, and replacement of deteriorating underground lines that lack protective casing. The Hawaiʻi Kai Neighborhood Board is set to meet Tuesday, November 24, at 7 p.m., and the Kuliʻouʻou–Kalani Iki board's next regular meeting falls on Wednesday, December 2.
