In the ‘Natural Gas 101’ series here on ‘The Hot Spot’, we will be writing different posts to help educate you on various natural gas issues. What is DDDC? Have you ever looked at your natural gas bill and wondered how it all comes together? One line of your bill includes your DDDC which stands for Dedicated Design Day Capacity. The DDDC Factor is a calculation done by Atlanta Gas Light Company (AGL) and is unique to each home or business. Basically, AGL is responsible for having enough pipe and storage capacity to meet every customer’s need during extreme cold weather conditions. For most residential customers and small businesses, natural gas is used for heat. And when it’s cold outside, you’ll want enough natural gas to keep your home or business warm. Your DDDC factor indicates how much natural gas deliverability is reserved (or ‘dedicated’) for your home or business if Atlanta were to reach an average daily temperature of 10oF (a ‘design day’). You’ll see the DDDC Factor on your bill because it is used to calculate a customer’s AGL Pass-Through Charges. Why did my DDDC change? AGL recalculates and updates the DDDC at your location annually, so each September you will see an updated DDDC on your bill. During this yearly calculation, AGL reviews the past gas consumption and usage pattern at your home or business. The most important influence on your DDDC calculation is how much gas was used last year during the coldest period of the year compared to your typical summer usage (if any). A calculation is done to determine how sensitive your consumption is to cold weather and then used to set your DDDC indicating how much capacity should be reserved for your home or business. Because your DDDC affects the AGL Pass-Through Charges, you may see a change in the amount of your bills year to year if your DDDC is adjusted. Remember, your DDDC is tied to your location rather than you. So, if you move, your DDDC will be changed to the DDDC of your new location and then will be reset, as usual, in September.

Back to the hot spot home ... |
I have charges for a customer service fee, an AGL Pass Through Charge, and Taxes each month although I don’t have any gas consumption for the majority of the year in the summer months 0 CCFs.
Is there some way to avoid these fees when I’m not consuming any product? I’ve looked into this before and I think there was a re-connect charge that amounted to more than just paying the fees and taxes?
Bill, thanks for the comment! There is a way that you can avoid paying the customer service fee, AGL Pass Through charges, and taxes throughout the warmer months. We call our customers that chose this option Seasonal Customers. You can turn your gas off in the spring and turn it back on in the fall, but there is a reconnect fee associated with the process. Depending on your account, you may find savings by going seasonal. We’ve sent an email to the address listed here and we’d love to take a look at your account for you to help you determine if this is the right option for you. Please reply to the email with your account number and we will call you to figure out how we can help. Thanks for reading Bill!
