Adjustments
Purchased Gas Adjustment
The purchased gas adjustment (PGA) is used to adjust the retail price of gas to cover wholesale gas price fluctuations. It is calculated on a per CCF basis using the difference between the actual price of gas and the price that was assumed when the base rate was determined. It can be either a positive or negative value, and appears as a separate line item on the customer's bill.
