It is the dreaded piece of mail every Hawaii resident hates opening: the monthly Hawaiian Electric (HECO) bill.
In 2026, Hawaii continues to have the highest electricity rates in the entire nation—often triple the national average. For homeowners, the solution is obvious: install rooftop solar panels. But if you live in one of HAPI’s managed rental properties (or any apartment on the island), you do not have that luxury. You are at the mercy of the grid.
When your HECO bill spikes to $250 or $300 for a simple two-bedroom apartment, it can entirely derail your monthly budget. But you are not powerless. Here is the definitive guide on why Hawaii electricity is so expensive, and 5 renter-friendly hacks to drastically lower your bill without breaking your lease.
Why Are Hawaii Electricity Rates So High?
The island tax on the power grid.
Before you blame your property manager, you need to understand the structural problem. Hawaii is an isolated island chain. We cannot plug into a neighboring state’s power grid when we need extra juice.
Historically, the majority of Hawaii’s electricity has been generated by burning imported oil. When global oil prices surge, your HECO bill surges. While the state is aggressively transitioning to renewable energy (wind and solar farms), upgrading the aging grid infrastructure costs billions—and those costs are passed down to the consumer via the “Base Fuel” and “Energy Cost Recovery” lines on your bill.
You can’t change the per-kilowatt-hour (kWh) rate, but you can change how many kilowatts you consume.
5 Renter-Friendly Hacks to Lower Your HECO Bill
Changes you can make today without asking your landlord.
1. Defeat the “Vampire Draw”
Did you know that up to 20% of your electric bill comes from appliances that are turned “off”? Devices like older TVs, gaming consoles (PlayStation/Xbox), microwaves, and laptop chargers continuously draw power just by being plugged into the wall. This is called a “vampire draw” or “phantom load.”
- The Hack: Buy a $10 smart power strip. Plug your entertainment center into it, and flip the single switch off when you go to bed. You will save $15-$25 a month instantly.
2. Master Your AC Etiquette
Air conditioning is the #1 culprit of high electric bills in Hawaii. A single window AC unit running all day can add $100 to your monthly bill.
- The Hack: Never set your AC below 74 degrees (78 degrees is the energy-saving sweet spot). Do not run the AC when you are not home. Most importantly, clean the filter every 30 days. A clogged filter forces the compressor to work twice as hard, burning massive amounts of electricity.
3. The Refrigerator Reality Check
Your fridge is the only major appliance that runs 24/7/365. If it is working inefficiently, it is quietly draining your wallet.
- The Hack: Pull the fridge slightly away from the wall and vacuum the dust off the coils in the back. Check the temperature settings: the fridge should be at 37°F and the freezer at 0°F. If your landlord provided an older fridge, make sure the rubber door seals are airtight. If they are cracked and leaking cold air, submit a maintenance request to have them replaced.
4. Switch to Cold Water Laundry
Heating water accounts for nearly 15% of an apartment’s energy use. If you have an in-unit washer and dryer, your laundry habits dictate a large portion of your HECO bill.
- The Hack: Wash your clothes in cold water. Modern detergents are designed to clean perfectly without hot water. Furthermore, hang dry your clothes on a drying rack on your lanai whenever possible. Running an electric dryer costs about $1.50 per load in Hawaii.
5. Swap to LED Bulbs (Yes, Even in a Rental)
If your apartment came with older incandescent or CFL bulbs, they are generating heat and wasting money.
- The Hack: Go to City Mill or Home Depot and buy a pack of LED bulbs. Replace the bulbs in the fixtures you use the most (kitchen, living room, bedside lamps). When you eventually move out, you can take your LED bulbs with you and put the old ones back.

The True Cost of Running Appliances in Hawaii
Stop guessing. Here is the math based on 2026 HECO rates (approx. $0.40/kWh).
| Appliance | Usage Pattern | Estimated Monthly Cost (Hawaii) |
|---|---|---|
| Window AC Unit (8,000 BTU) | 8 hours/day (Overnight) | $85.00 – $110.00 |
| Electric Water Heater | Standard family usage | $60.00 – $90.00 |
| Older Refrigerator | 24/7 continuous operation | $35.00 – $50.00 |
| Electric Dryer | 5 loads per week | $25.00 – $35.00 |
| Standing Fan | 12 hours/day | $8.00 – $12.00 |
The Takeaway: If you run two window AC units every night, you are easily adding $200 to your monthly bill. Switching to ceiling fans or standing fans can save you over $150 a month.
Frequently Asked Questions
Is my landlord allowed to charge me more than the HECO rate?
No. If your apartment is “sub-metered” (meaning the landlord receives one big bill and splits it among tenants), Hawaii law strictly prohibits landlords from marking up the cost of electricity for a profit. They can only charge you for the exact kilowatt-hours you consumed at the actual HECO rate.
What is "Time-of-Use" (TOU) and should I opt in?
HECO offers a “Time-of-Use” rate plan where electricity is cheaper during the middle of the day (when solar power is abundant) and much more expensive during the evening “peak” hours (5 PM to 10 PM). For most renters, TOU is a bad idea. Because renters are usually at work during the day and use most of their power at night (cooking, AC, TV), the TOU plan will likely increase your bill.
What if I simply cannot afford to pay my electric bill this month?
Do not let your power get shut off. Apply immediately for LIHEAP (Low-Income Home Energy Assistance Program). This federal program provides a once-a-year credit directly to your HECO account to prevent disconnection. You apply through the Honolulu Community Action Program (HCAP) on Oahu.
Can I force my landlord to upgrade to energy-efficient appliances?
Unless an appliance is completely broken and no longer functions, a landlord is not legally obligated to upgrade a working refrigerator or AC unit to an Energy Star model just to save you money on your electric bill. However, it never hurts to ask politely when it is time to renew your lease!
