YANKTON, S.D.(WNAX)- There were concerns last fall about the availability and cost of natural gas.

Tom Glanzer with Northwestern Energy, says at mid-winter, prices have backed off some.

Glanzer says gas supplies should be adequate to get to the end of winter.

Glanzer says there are ways they can help customers control their monthly gas bills.

Glanzer says customers are still paying off the massive spike in costs that was caused by the Texas freeze up last February.
