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

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
Always call 8-1-1 before you dig
If you're planning a home or landscaping project, call Pennsylvania One CAll at 8-1-1 at least three business days before digging. A representative will mark the approximate location of underground utility lines for free.

Please be advised, if more than one Distribution charge exist on your bill, there may have been a rate change.

The Pass-Through Charge may include: the Purchased Gas Demand Charge (PGDC); the PGDC “E” Factor; the Capacity Assignment Factor (“CAF”); the Rider Customer Choice charge (“Rider CC”); and the Rider Universal Service Plan Charge (“Rider USP”). If you need further break down of these factors, please see our state tariff approved by the Public Utilities Commission.
Distribution System Improvement Charge - This is a monthly charge to recover a portion of Columbia Gas’ distribution system infrastructure costs.
Gas Supply Charges - This is the cost of gas. Columbia Gas does not make a profit off of the Supply charges. If you participate in the Choice program, this amount will be listed under Supplier’s portion of your bill. Please be advised, if you have more than one gas supply charge on your bill, there may have been a rate change.
Gas Cost Adjustment - This is the amount billed or credited each month to account for the difference between Columbia’s projected and actual gas supply costs. Each year, Columbia Gas submits a filing to the Public Utility Commission detailing the actual cost of the natural gas we purchased in the previous year as compared to the amount we billed our customers for that gas. The purpose of this filing is to reconcile those two accounts. Since gas supply charges from Columbia Gas of Pennsylvania are required by regulation to be a dollar for dollar pass through, any differences that are found must be either refunded to or recovered from our customers.
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 November through May. 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 adjustment will only appear if the temperature is more than 3% colder or warmer than normal during the billing period.

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.
Adjusting your bill based on weather
The Weather Normalization Adjustment (WNA) is a method of billing based on “normal” weather approved by the Pennsylvania Public Utility Commission. Today, we utilize 20-year average temperature information provided by the National Oceanic and Atmospheric Administration (NOAA) to define normal weather and the Degree Days Deficiencies method to determine heating requirements. This recognized standard enables Columbia to remove the effects of abnormal weather on the delivery portion of your bill during the heating season (November through May).
How does it work?
The delivery charge usage is adjusted to reflect “normal” weather rather than actual weather. So, if the weather is colder than normal, the WNA is a credit that reduces the amount of the delivery charge. If it’s warmer than normal, the WNA is a debit that increases the amount of delivery charge. Over time, your bill should total the same as it would without applying the WNA, which simply provides a more even method of collecting delivery costs.
