Natural gas cost
Effective with June billing, Columbia Gas of Kentucky's gas supply cost has increased from $5.8189 to $9.6340 per Mcf. This rate will remain in effect until the next regular quarterly adjustment in September 2025.
The Actual Cost Adjustment
Each quarterly gas cost adjustment is a projection of what Columbia Gas expects to pay for the natural gas it purchases for its customers in the upcoming quarter. That rate is derived from a formula that considers current and projected market prices, storage costs, and interstate pipeline charges.
Although these quarterly projected costs are based on the most current data available, they are estimates. Since Columbia Gas does not profit from the cost of gas, these estimates must be reconciled to what was actually paid. This reconciliation ensures that customers pay exactly what Columbia Gas paid for their natural gas supply. The reconciliation is known as an actual cost adjustment. The actual cost adjustment may be applied as either a charge or credit, depending on whether Columbia Gas overestimated the cost of natural gas purchased or underestimated the cost. This charge or credit is embedded in the customers' gas supply cost.
The Kentucky Public Service Commission must approve all gas cost adjustments.
