No, True Natural Gas purchases the gas that you consume and makes sure that it is delivered to the Atlanta Gas Light (AGL) service territory. AGL maintains the local network of gas pipes to serve gas to your home or business, as well as the meters that measure your usage. AGL also maintains liquefied natural gas (LNG) facilities to use on the coldest days of the year.
Typically, natural gas comes from offshore wells in the Gulf of Mexico—primarily in Louisiana and Texas. The gas is "transported" through large-diameter pipelines to Georgia by federally regulated companies like Transco and Southern Natural. The gas is transferred into Atlanta Gas Light's distribution pipeline system at what is known as a “city gate,” which, practically speaking, is a large meter that records the volume of gas. Once the gas enters AGL's system, AGL distributes it to the end use customer.
A therm is a measure of energy equivalent to 100,000 BTUs. A BTU, or British Thermal Unit, is the quantity of heat required to raise the temperature of one pound of water by one degree Fahrenheit. To give you some idea of scale, the typical home will consume approximately 700 therms annually. Gas that you consume is recorded by the gas meter in terms of volume (cubic feet) instead of energy. On your bill, you will see a thermal factor (BTU factor) that indicates how much heat or "thermal content" per hundred cubic feet (CCF) is in the gas that you used. This factor is used to convert your usage to therms.
