Purchased Gas Adjustor

The Purchased Gas Adjustor (PGA) is a usage-based charge or credit that reflects changes to the costs of natural gas. UniSource passes along these costs without any markup, and earns no profit through the PGA. The PGA is periodically reviewed and approved by the Arizona Corporation Commission.

How will the PGA affect my monthly natural gas bills?

The impact varies with usage and the current PGA rate, which is adjusted monthly.

Where can I view the current PGA rate?

The current rate is updated monthly and listed in our gas rates section here.

How does the PGA appear on my monthly bill?

The PGA appears on your bill under the heading “Gas Supply Charges” as the “Cost of Natural Gas” charge or credit.
