Understanding Your Bill

Why does my bill amount change every month?

There are many factors that go into how your bill is calculated. Some of the factors that may change your bill each month include:

  • The weather and seasons (Spring, Summer, Fall, Winter) - Colder days usually mean you may be using more gas to keep your home warm
  • Days in your billing cycle
  • A change in lifestyle where you may be using more or less gas compared to previous months

Click the link below to login to our My Account portal and view the My Usage page to compare your usage, the weather and more to prior months.

How to detect natural gas

If you smell a rotten-egg-like odor, you could have a gas leak. Natural gas is naturally colorless and odorless. We add an odorant called mercaptan to natural gas, which gives it a distinctive smell, similar to rotten eggs or sulfur.

In some cases, you can also identify natural gas by sight or sound. If you see blowing dirt, bubbling water or dead vegetation, or hear a hissing or roaring sound, that could be caused by natural gas.

Follow these tips if you detect natural gas:

1. Stop what you’re doing

Don't smoke or light a match. Don't open the windows. Don’t use anything that could cause a spark, like a phone, light switch, appliance or flashlight. Don’t start your car or use your garage door to leave.

2. Leave the area immediately

If you're inside, get out immediately. If you're outside, leave the area quickly.

3. Call 911 and us

From a safe location, away from the building, call 911 and our emergency number at 1-888-460-4332  and wait for crews to arrive.

Always call 8-1-1 before you dig

If you're planning a home or landscaping project, call Miss Utility at 8-1-1 at least two business days before digging. A representative will mark the approximate location of underground utility lines for free.

We want to ensure you know what you are paying for on you monthly bill statement. Check out the glossary of terms below to help you understand the detailed charges on your bill.

System Charge - A fixed charge that appears on each customer bill and that covers such local distribution company costs as maintaining the gas lines, meter reading and billing.

Distribution Charge - The charges for the delivery of natural gas from Columbia Gas to its customers.

Revenue Normalization Adjustment (RNA) - The RNA included in the Distribution Charge is designed to more accurately recover those costs incurred by Columbia Gas which do not vary with the actual volumes of natural gas used by customers. The RNA ensures that we recover no more and no less than the allowed distribution revenue per customer approved by the PSC. The monthly bill for the gas used will continue to be based on actual usage, meaning that customers will save money by using less gas. A credit is issued when the actual distribution revenue exceeds the allowed distribution revenue. A debit or surcharge is issued when the actual revenue is less than allowed.

Infrastructure Replacement and Improvement Surcharge - This is a fixed charge which funds’ investments to replace aging pipes in the distribution system so that Columbia Gas can continue to provide safe and reliable service.

Gas Supply Charges - This is the cost of gas. Columbia Gas does not make a profit off of the Supply charges.

Volumetric Franchise Tax - Public Service Companies must pay a Franchise Tax for the privilege of doing business in the State of Maryland. The Franchise Tax is calculated, in part, based on gross receipts.

Weather Normalization Adjustment - The Weather Normalization Adjustment (WNA) is a method of adjusting customers’ bills to reflect normal, rather than actual, weather conditions during the months of December through April. The WNA has a leveling effect on customers’ gas bills by reducing bills in months with colder-than-normal temperatures when customers’ gas usage tends to be higher and increasing bills in months with warmer-than-normal temperatures when customers’ gas usage tends to be lower. As a result, customers are less impacted by large monthly swings in their gas bills which can occur during the heating season as a result of increased usage during colder weather.

* This sample bill is an example of a residential Columbia Gas customer's bill and is for illustrative purposes only. The bill displayed is representative and does not reflect all possible items that could appear on your bill. The dates, rates, values and charges shown are for educational purposes and will differ from those shown on your actual bill statement. Rates, riders and tariffs are subject to change upon regulatory filings and subsequent approvals. View your bill statement for current rates and actual charges.

What is therm billing?

Therm billing is designed to provide you with a more accurate bill that allows us to bill you for the quantity of energy consumed, rather than the volume of natural gas consumed. This billing method is consistent with the way natural gas is bought and sold in the wholesale marketplace.

Do I need to make a deposit to open an account?

Depending on your credit report, you may be required to pay a security deposit to get service in your name. The deposit is security that the final bill will be paid. It can’t be used to pay current or delinquent bills. The deposit will be applied to your account after you establish a good payment history for 12 months or when you receive a final bill after you stop service.

Thank you for your response.

Can I save money through the Budget Plan?

The Budget Plan is a great tool for spreading your winter heating costs more evenly across an entire year, although it’s not designed to reduce your total costs. It will allow you to know what you can expect to pay each month, and should allow you to have more spending money available during the holidays. It’s easy to sign up, and it’s free.

Thank you for your response.

Why is my bill so high?

Your gas bill will fluctuate depending on the weather, season of year, change in lifestyle or addition of family members. To understand your usage and learn how to save on your energy bill:

  1. Sign into your account.
  2. Select the My Usage option in the menu.
  3. Compare your usage by month, year, average temperature and number of billing days.

Yes, you can enroll at any time. However, the budget season starts in May and the fewer months you have to spread the costs may result in a higher budget amount.

When will my budget account be reviewed next?

The next budget year begins in May. We review your account in May to establish a budget payment amount for the next 12 months. We review it again in December to see if any adjustments are needed based on the current budget balance and projected cost and usage.  Settle Up occurs in May and the new Budget year begins in June.

If you decide you want to be removed from Budget Plan, you can remove your enrollment in your web account at any time. If you cancel your Budget Plan, your full account balance will be due on your next statement rather than your Budget amount.

Thank you for your response.

What is the value of therm billing?

Therm billing matches the way natural gas is bought and sold in the wholesale marketplace, so we bill you for the heating value of the product. You’re billed based on the heat value instead of just volume of gas used. We take natural gas into our system from various sources, and customers could have received more energy than others using the same amount of gas because the heat value of the gas received was higher.

Thank you for your response.

What is the difference between budget billing and my actual billing?

Budget billing is our Budget Plan program. It calculates your Budget payment amount based on the history of usage at your address, square footage of your home or building, the projected cost of service, and rates for service and delivery. Your actual billing is based on our regular rates and the actual energy you use.

Thank you for your response.
