Learn how to read your Washington Gas bill to monitor your energy costs and effectively compare utility rates.


Thank you Washington Gas customers for asking us some important questions about your bill. All WGL companies, including Washington Gas, are here to provide energy answers. So we’ve put this video together to address some common bill-related questions. First: gas distribution and supply charges. What’s this about? These are separate services, and relate to very different things. With all of the different parts of the bill, including calculations, tariffs and other factors that contribute to the entire bill amount, we appreciate how confusing reading and understanding your bill can be. Your gas bill is made up of the combined total of two parts: gas distribution and gas supply charges. First, let’s define the gas distribution charge. This is what Washington Gas charges you for delivering the gas, including the cost to operate and maintain the gas system safely and reliably as well as respond to customer calls and requests for service. All of which is overseen by the three utility regulators in Washington Gas’ service territory: The Public Service Commision of the District of Columbia, The Maryland Public Service Commission and the Virginia State Corporation Commission. Washington Gas charges you for the safe and reliable delivery of natural gas to your business or home, using our pipeline infrastructure. The second part is the gas supply charge. Which is strictly for the cost of the natural gas you consume during a period of time and is measured in therms. Because you have a choice in whom you actually buy natural gas from, this charge could represent the cost per therm you have agreed to in your contract with an independent supplier. The more you use, the more you pay. When you buy your gas from Washington Gas, these charges come from different suppliers, which allows us to negotiate the best price for our customers and keep a constant supply of natural gas, no matter the weather. You pay what we actually pay for the gas. No matter who you choose, Washington Gas will deliver that natural gas to your home or business safely and reliably. And with natural gas consumers in our area, winter bills (usually between October and March) are typically higher than during spring and summer months. Here’s how you can understand why your bill will vary from month to month. First, check you consumption, or how much gas you used, which can be one of two reasons you bill has changed. Did you need to use a lot of gas in the last month, for example for heating your home? Was the weather colder than usual, and did you need to run you natural gas appliances longer or more often? Sometimes due to market factors and demand, the price we pay to buy the gas can fluctuate up or down and may affect the gas supply portion of your bill. This could be seen in the cost per therm charge in this area of the bill. If you’re having difficulty paying your bill, please contact us so that we can work with you using tools like our Budget Billing Plan, Hopefully this video will help you understand and navigate through the different parts of your bill and charges.
