What is a Purchased Gas Adjustment or PGA?
The PGA, or purchased gas adjustment, is the actual cost for natural gas. This cost, or portion of the rate, is what Spire pays for natural gas – with no markup.
The PGA is adjusted at least once every year, in November, to accurately reflect the cost we pay for natural gas.
The PGA can be higher or lower than the previous year, depending upon the price of natural gas and costs associated with interstate pipelines. So, if the cost of natural gas is now higher than what’s been billed over the past 12 months, the PGA will be higher. And if the cost of natural gas is lower than what’s been billed, the PGA will be lower.
And moving forward, your natural gas costs will be based on your usage charged at the updated rate. Spire’s PGA is reviewed and approved by the Missouri Public Service Commission (MPSC).
Why has the PGA changed?
Changes in natural gas prices can mean a lower or higher PGA on your bill compared to your previous statement. The PGA reflects the cost Spire pays to purchase natural gas, which is then passed along to you with no markup.
The price Spire pays for natural gas is reflected in the details section of your bill as the natural gas cost, with no markup passed along to customers. You pay what we pay.
