Hawaii pays more for electricity than any other state in the country, and the reason has nothing to do with a bad deal or a provider you failed to shop. There is no provider to shop. Hawaii is a fully regulated market: one utility per island sets the rate, the state's regulators approve it, and every homeowner on that island pays it. Here's why the rate landed at 40.6 cents per kWh, what's actually driving the climb, and what a homeowner can do about the bill that has nothing to do with switching companies.
The straight answer
No, you can't choose your electricity provider in Hawaii — and there's no workaround. The islands are served by regulated utility monopolies: Hawaiian Electric covers Oahu, Maui, Lanai, and Hawaii Island, while Kauai runs on its own member-owned cooperative, the Kauai Island Utility Cooperative (KIUC). Whichever of these serves your address is your only option, full stop. Rates aren't set by a competitive market; they're set through a Public Utilities Commission (PUC) rate case, where the utility (or, for KIUC, its member-elected board) proposes rates and regulators approve, adjust, or reject them.
This isn't a gap in the system waiting to be fixed — it's the deliberate structure for an isolated island grid. Each Hawaiian island is its own electrical grid with no interstate transmission lines to lean on, which is a poor fit for the multi-provider competitive markets that work on a large interconnected mainland grid. A single regulated utility per island, answerable to the PUC, is the tradeoff Hawaii has made instead. There is no shopping site to link to here, because there is nothing to compare.
What electricity costs in Hawaii
Hawaii's residential rate averaged 40.6 cents per kWh in 2025, per EIA preliminary data — the highest of any state, and roughly triple the national average. The chart below shows the full federal price history for Hawaii, with a dashed projection of where the rate goes if the last decade's pace simply continues — drag across it, or compare Hawaii against another state.

The number to sit with is the 96 percent increase since 2005. That's not a spike from one bad year — it's two decades of a rate roughly doubling, and the pace hasn't slowed: over just the last ten years it has climbed at about 3.2 percent a year, faster than general inflation in most of that stretch. For a homeowner, the practical read is that the rate itself is the dominant driver of a high bill in Hawaii, more than unusually heavy usage — and a rate that has climbed this consistently for twenty years is a reasonable one to expect will keep climbing, which changes the math on efficiency and solar investments made today.
Why your rate is set the way it is
Two structural facts explain most of the gap between Hawaii and the mainland. First, the islands historically generate a large share of their electricity by burning imported petroleum — oil that arrives by ship, prices set on global markets, with none of the cheap regional coal, natural gas pipelines, or large-scale hydro that keep costs down in much of the continental U.S. When global oil prices move, Hawaii's generation costs move with them, and that shows up in the next rate case. Second, each island is its own small, isolated grid — there's no economy of scale from serving a large interconnected region, and building and maintaining generation and transmission infrastructure on remote islands costs more per customer than on the mainland.
The rate-setting process itself is a PUC rate case: the utility files a request showing its costs — fuel, grid maintenance, generation investment — and the Hawaii Public Utilities Commission holds proceedings, hears from consumer advocates, and approves, trims, or rejects the request. Homeowners don't get an individual seat at that table, but the PUC's proceedings are public record, and the rate you pay today is the outcome of that process, not an arbitrary sticker price.
How to actually lower the bill
Since there's no provider to switch, every lever here is about using less, using smarter, or generating your own.
Efficiency first. Cooling, water heating, and appliances dominate a typical Hawaii electric bill. A heat-pump water heater uses a fraction of the electricity of a standard resistance unit and is often the single biggest efficiency upgrade available in an island home. Ceiling fans and smart use of natural ventilation can cut air-conditioning hours substantially in a climate that rarely gets genuinely cold. LED lighting and unplugging idle electronics round out the easy wins.
Rate schedule and billing options. Ask your utility whether a time-of-use rate is available for your account — some Hawaii rate schedules offer lower prices during off-peak hours, which rewards shifting laundry, dishwashing, and EV charging to those windows. If it's the swings in your bill rather than the total that's the problem, ask about budget billing (sometimes called levelized or average billing), which spreads your estimated annual cost into equal monthly payments instead of chasing seasonal peaks.
Rooftop solar. This is where Hawaii's high rate actually works in a homeowner's favor. Strong, consistent sun plus a rate of 40.6 cents per kWh — one of the highest anywhere — means every kilowatt-hour a rooftop system generates offsets some of the most expensive grid power in the country, which typically shortens the payback period compared to lower-rate states. The catch is that the exact economics depend heavily on your utility's current net-metering or net-billing terms, which have changed more than once in Hawaii and vary by island and by when you interconnect. Run the numbers against your actual utility's current program before committing — see our solar panels guide for the full breakdown.
The practical checklist
- Confirm your utility and rate schedule. Know whether you're on Hawaiian Electric or KIUC, and ask what rate schedules — including time-of-use — are available for your account.
- Pull twelve months of bills. Find your kWh usage by month before evaluating any efficiency or solar investment; the payback math depends on your real numbers, not an average.
- Fix water heating first. A heat-pump water heater is typically the highest-leverage single upgrade in a Hawaii home.
- Ask about time-of-use and budget billing. Both are free to ask about and can lower or smooth your bill without any equipment purchase.
- Get a real solar quote against your current net-metering terms. Don't rely on a general "solar is worth it in Hawaii" rule — get the specific numbers for your utility, island, and roof.
- Track the rate case docket. The Hawaii PUC's proceedings are public; a pending rate case is early warning that your bill is about to move.
None of this replaces the basics covered in our electrical guide — panel capacity, wiring condition, and safe upgrades still matter for a home's overall electrical health regardless of what the rate is doing.
