How Atlanta Gas Light (AGL) Charges For Its Services

Regardless of the marketer chosen, customers will see base charges from Atlanta Gas Light (AGL) on their monthly marketer statements.

What these base charges cover:

Delivery: Moving the gas through the system to your door.
Infrastructure: Maintaining the actual pipelines.
Service: Reading your meter to see how much you used.

What is included in my AGL base charges?

Customer Charge: A flat monthly fee for gas connection to your home or business.
Dedicated Design Day Capacity (DDDC): A charge based upon a customer’s projected usage for the coldest day of the year.  (Links to section below)
Meter Reading: The cost to read your gas meter.
Peaking Service: The cost of operating company-owned, above-ground storage facilities. This helps ensure an adequate supply of gas on the coldest day of the year. (Atlanta and Macon areas only).
Franchise Recovery: Reimburses the Atlanta Gas Light for fees paid to local governments for the use of public rights-of-way for natural gas lines and other facilities. 
Social Responsibility Cost Rider: Funds gas discounts for low-income seniors.
Environmental Fee: Recovers expenses for the cleanup of old gas plant sites.
System Reinforcement: Covers the cost of strengthening pipelines and improving gas pressure.
ECON-1: Recovers costs associated with natural gas investments directed by the PSC that provide wider public benefit to the communities in which they are located.
DOT Rider: Covers the cost of moving pipes due to road construction or widening by the Georgia Department of Transportation.

What is my DDDC factor?

What it pays for: It covers the cost of having enough pipe capacity to serve you on the coldest day of the year.
Annual update: Every September 1, your DDDC factor is updated and approved by the Georgia Public Service Commission based on your usage from the previous year.
How it’s calculated:  
Existing buildings: AGL looks at your past usage patterns or the number of gas appliances and how many gas appliances you have to determine a location’s demand on the system.
New buildings: If there’s no history, AGL estimates based on square footage and equipment and appliance types and quantity.
Why it changes: If you add a gas fireplace or stop using a gas heater, your usage pattern changes, which can shift your DDDC.
Disputes: If your factor seems too high, contact your marketer to review it.

How Are AGL Rate Amounts Determined?

The Georgia Public Service Commission (PSC) regulates AGL’s rates through an annual review called Georgia Rate Adjustment Mechanism (GRAM).
How it works: Once a year, AGL submits its costs— based on historical expenses adjusted for inflation, and forecasted capital expenditures, revenues, labor and benefit costs—to the PSC.
The result: Rates are adjusted up or down to reflect the actual, current cost of providing utility service.
The goal: Pricing that is a transparent and continuous process through GRAM adjusting with real-time changes in factors that influence utility rates.
Basically: Your rates change annually based on a public review of AGL’s real business expenses.

How Natural Gas Marketers Charge For Their Services

Pay by the “Therm”: Marketers charge for the natural gas delivered to your home or business on a per-therm basis. A therm is a standard unit of heat energy.

Extra Fees: Other charges for items like customer service, special programs, or early termination.

Compare Carefully: Because pricing plans and contract terms vary by marketer, customers should review all conditions carefully before enrolling. Written confirmation of selected plans and contract terms is strongly recommended. Some marketers may offer discounted pricing for senior citizens. Customers who believe they may qualify should inquire directly with their chosen marketer.

How Do I Calculate My AGL Base Charges?

DDDC Calculation Example

Your DDDC factor is (found on your bill), the AGL capacity rate is per unit and the billing cycle is days.

The calculation is:
Formula:
DDDC Factor x AGL Rate x Days
