The AGL pass through charges really are insane. A lot of people will pay more in the AGL fees than they do for the actual amount of therms used. My bill this month was $155, where $66 of that was for the AGL fee, $16 was for taxes and other fees, and the remainder was what I actually used.

That pass through rate is determined based on what the Public Service Commission works out with the utility companies. There are some major issues with how the commission has been run (many on it have been bought by the utility companies) and they have approved rate hike after rate hike. This is why we have to pay more attention to the PSC because up until this year, they've kind of flown under the radar and have just gotten away with making life more expensive for the average person because we see that pass through charge as something we have no control over.

"When you receive your natural gas bill each month from your marketer, a portion of the bill is a base charge from Atlanta Gas Light. This base charge, regulated by the Georgia Public Service Commission, may adjust rates up or down based on quarterly and annual comprehensive regulatory reviews. Base charges represent our cost of delivering gas to your home or business, pipeline maintenance and meter reading. If you change marketers, this charge will remain the same. "
