Hawaii’s Electricity Bills Spiked 22% in May

The latest update to the Electricity Price Hub shows a price increase in line with what regulators predicted.

Hawaii already had the most expensive electricity in the country. Then the war in Iran happened.

America’s 50th state has no domestic fossil fuel industry and no access to the continental United States’ natural gas pipeline network, and is therefore uniquely dependent on imported oil to generate electricity. (The state’s last coal plant shut down in 2022.)

While Hawaii’s electricity prices and household bills have spiked along with oil prices since the United States and Israel attacked Iran in late February, the average electricity bill in Hawaii shot up to $248 in May, compared to an already-high $203 in April, according to the latest data in Heatmap and MIT’s Electricity Price Hub, released Monday. The average price of electricity rose by 6 cents per kilowatt-hour, from 46 cents in April to 52 cents in May. Nationally, average prices stand at around 17.5 cents and are up 3.6% (or just over half a cent) from May of last year, with national average bills of $140 per month up about $6 from a year ago.

Hawaii’s eye-watering prices far outmeasure even the state’s peers in expensive electricity. May bills for California were $137, for instance, while prices were 25 cents per kilowatt-hour. In Massachusetts, where prices have also spiked this spring, they only got to 38 cents per kilowatt-hour. Maine, which has been struggling with high prices thanks to high costs linked to storm recovery, prices in May were 28 cents per kilowatt-hour, up about 10% from a year ago, but down substantially from the 35 cents per kilowatt-hour in February.

The situation in Hawaii was pretty much a foregone conclusion way back in April. Hawaii’s Department of Commerce and Consumer Affairs warned customers that bills from Hawaiian Electric, which serves almost the entire state, would almost certainly go up between 20% and 30% from then through June.

“We told our customers to prepare for potential increases in energy costs in the coming months, driven by rising global oil prices linked to escalating geopolitical tension,” Scott Seu, Hawaiian Electric’s chief executive, said in an April earnings call. “Affordability is a core focus of ours, and affordability pressures have intensified given the recent increase in fuel prices across the globe.”

Some Hawaii ratepayers will have the opportunity to claim a one-time credit on their bills this month as part of an annual rate relief drive by the Hawaii Home Energy Assistance Program. The state program is administered through local nonprofits and provides bill credits for households that claim some form of social assistance, like food stamps or Social Security or disability payments administered through Social Security

The benchmark global oil price was sitting at around $70 per barrel in the weeks leading up to the opening of the U.S.-Israel-Iran war, and is now around $95, down from a high of $118. While Hawaii ratepayers probably won’t feel comforted this is far from the worst-case scenario for runaway oil prices as public and private inventories of oil have largely filled the gaps. If the story of the energy effects of the Iran War in the United States is that some combination of trapped natural gas, inventory releases, and healthy domestic production have made the oil price hike manageable, it may only be in the non-insular United States.

According to analysis of price hub data from our partners at CleanEcon, customers in the Lanai division of Hawaiian Electric’s Maui service area faced an 18 cents per kilowatt-hour rise just from “recovery” for high energy supply prices, a nearly 60% hike, which on its own added $76 to average bills compared to the beginning of this year.

The good news is that due to its famously agreeable climate, Hawaiian households consume little electricity compared to the rest of the country. But with those electricity rates, who can blame them.

Data Center Moratoria Are ‘Unconstitutional,’ Lawsuits Claim

A new front opens in the data center wars.

A series of lawsuits filed in federal court asks a big question – are data center moratoria constitutional?

In early August, data center developer DC Blox sued the city of Nashville in federal court to overturn a zoning moratorium stopping them from building a hyperscale facility adjacent to the city zoo. “The Data Center Moratorium, moreover, is a targeted attack against DC BLOX, in violation of federal constitutional protections,” the suit argued, claiming that it defied the corporation’s due process and equal protection rights.

Local Permitting Fights Take Over National Politics

And more on this week’s conflicts around project development.

The United States.

1. Montgomery County, Pennsylvania – We reached a new normal in the data center backlash, and it all seems to have started in King of Prussia.

  • On Tuesday, Pennsylvania Gov. Josh Shapiro announced his state – one once coveted by the AI industry for hyperscale construction – will no longer permit projects without local support. It was a step change from posture taken mere months earlier, when he announced voluntary standards for data center development that I found may have been vetted by representatives of the industry, including Amazon.
  • Tucked in Shapiro’s speech was what I can only imagine was his last straw: developer Brian O’Neill’s efforts to construct data center buildings in the King of Prussia community, close to where he grew up himself. Without calling him out by name, the governor said he was “stoking fear in the community, even though he has no realistic path to getting power at the sites any time soon.”
  • “Here’s something else he has no realistic path to getting: my support,” the governor said.
  • As the climate news outlet DeSmog wrote earlier this month, O’Neill had closely collaborated with members of Shapiro’s administration for more than a year before this speech happened, including on securing energy. But the real estate magnate’s projects kept facing local rejections; people really don’t seem to want what he’s been selling.
  • Now Shapiro is turning on O’Neill, transforming him into what he described as a type of “speculative” developer his government wishes to discourage from building projects in his state.

2. Columbia County, Wisconsin – The gubernatorial race in this state is transforming local fights over wind projects into must-watch popcorn fodder for anyone obsessed with the state of the energy transition, or national politics for that matter.

Q&A

A CNN Reporter Joins the Fray

A conversation with Ella Nilsen — formerly of CNN, now with Echo Communications — about where we stand in the fight over the energy transition.

The Q&A subject.

This week’s conversation is with Ella Nilsen, who recently left CNN as a climate reporter and is now a new vice president at energy and cleantech PR firm Echo Communications. Having worked on Capitol Hill alongside Nilsen, I knew her to be an exceptional reporter who asked hard questions of those in power on all sides. So when I found out she was taking her journalism hat off and putting the comms cap on, I wanted to do something you rarely get to do with one of your reporting peers: ask for her own opinion about where we stand in the fight over the energy transition.

Our chat was lightly edited for clarity.
