Hawaiʻi Gas sends a bill each month to our customers for gas services provided in the previous month. The elements on your bill will depend whether you are a utility customer or a propane non-utility customer.

If you have questions or need assistance understanding your bill, please contact us.

1. 1. Account Summary
2. - A quick, at-a-glance overview of your recent account activity.
1. 2. Account Number
2. - Your Hawaiʻi Gas account number. Please reference this number whenever you contact us for service or support.
1. 3. Therms
2. - Therms are a standard measurement and billing unit for utility gas energy. It represents the quantity of gas that is consumed over a billing period. Therms are calculated by taking the difference between the last meter reading and the current meter reading and multiplying it by a factor. The factor converts the gas meter measurement to therms.
1. 4. UT Oahu RES Consumption
2. - The line item description on this sample billing statement indicates that it is Utility (UT) service on the island of Oahu for a Residential (RES) customer. This description may differ for each customer depending on the island and type of service (e.g., residential vs. commercial, utility vs. non-utility)
  - The value shown in the Therms column is the total consumption for the billing period.
  - The value shown in the Rate column (also known as "Base Rate" or "Commodity Charge") is the rate that is charged by and paid to Hawaiʻi Gas for gas usage as approved by the Hawaii Public Utilities Commission (HPUC). This rate, set and approved by the HPUC, will only change if you change to a different class of service or if a new rate case is approved by the HPUC.
  - The value shown in the Amount column (what you are charged) is calculated by Therms (consumption) multiplied by the Rate.
1. 5. Utility Residential Base
2. - This is a fixed monthly customer charge and is approved by the HPUC.
  - This monthly charge covers certain service costs, including maintenance and repair of customer lines and meters, and other customer-related expenses such as meter reading and billing.
1. 6. Fuel Cost Adjustment
2. - The Fuel Cost Adjustment is approved by the HPUC and allows Hawaiʻi Gas to pass variable fuel costs or savings to the consumer. The amount of adjustment fluctuates as the cost to produce and distribute utility gas fluctuates. This prevents Hawaiʻi Gas from making more money when fuel prices go down or losing money when fuel prices go up. The Fuel Cost Adjustment keeps utility gas pricing fair and equitable.
  - Since your billing statement period often includes days spanning two consecutive months, it is not uncommon to see two Fuel Cost Adjustment entries on one billing statement. The value shown in the Rate column will vary month to month as fuel prices change. The rate shown is prorated to the number of days in the month.
  - The amount you pay is calculated by Therms, which is prorated, multiplied by the Rate.
  - Hawaiʻi Gas does not profit on fuel costs; what we pay to manufacture SNG or purchase Propane, LPG, or LNG/RNG is what the customer pays.
1. 7. Utility Customer Appreciation Credit
2. - As a condition of the sale of Hawaiʻi Gas to Argo Infrastructure Partners, LP in July 2022, Hawaiʻi Gas has committed to provide a $7 million rebate to its utility customers over a 9-year period. The $7 million will be provided to utility customers in the form of a monthly credit for each active account. This credit will continue through June 2031. We’re conveniently calling this the Hawaiʻi Gas Utility Customer Appreciation Credit.
  - The credit shown represents the monthly share of the total rebate.
1. 8. Due Date
2. - Total payment due must be made on or before this date.
1. 9. Total Payment Due
2. - Your total outstanding balance for the billing period that must be paid on or before the Due Date.

1. 1. Account Summary
2. - A quick, at-a-glance overview of your recent account activity.
1. 2. Account Number
2. - Your Hawaiʻi Gas account number. Please reference this number whenever you contact us for service or support.
1. 3. Summary of LPG (propane) deliveries
2. - This section shows the deliveries of LPG (propane) to your tank(s) during the billing period. Each delivery made is identified by a delivery date, delivery ticket number and the gallons of LPG (propane) delivered.
1. 4. Consumption Charge
2. - The Consumption Charge is what you pay for LPG (propane). It is calculated by multiplying the gallons delivered to you by the Rate per gallon.
1. 5. Monthly Tank Customer Charge
2. - This is your fixed monthly customer charge which covers service costs such as maintenance and repair of gas cylinder(s) or tank(s), maintenance of regulators, and administrative costs such as billing.

1. 7. NU Oahu-State GET + County Surcharge
2. - Combined State of Hawaii general excise tax (GET) and applicable surcharges that counties apply on the state general excise tax.
  - "NU Oahu" indicates that this is a Non Utility service on the island of Oahu.
1. 8. Rate/Cost per gallon
2. - The rate charged to customers per gallon. This rate can change from time to time because it is dependent on outside market factors like the wholesale cost of propane, delivery costs, and labor costs.

Frequently Asked Questions

Where can I pay my bill?
We offer various payment options, including paying online with a credit card, debit/ATM card, or electronic check. You can also set up automatic payment from your bank account, send a check or money order by mail, or pay in person at any Hawai'i Gas branch office or a Western Union retail location.

How is gas consumption measured?
Synthetic Natural Gas and utility propane consumption is measured in therms. Non-utility propane consumption is measured in gallons.

What might cause my gas bill to vary each month?
Increased or decreased gas consumption due to weather or changes in occupancy can cause fluctuations in your gas bill. Although it rarely occurs, a substantial increase in your bill may indicate a leak. See our safety page on leak detection for more information. Also, the number of days in the billing period as well as changes in our cost to provide propane and SNG could also contribute to monthly differences in your gas bill.

What are some ways I can be more efficient with my gas usage?
From reducing your shower time to washing your clothes in cold water, there are lots of easy ways to increase your gas efficiency. Visit our Good Energy Tips page to learn more.
