YANKTON, S.D.(WNAX)- As temperatures cool, there will be more reliance on natural gas to keep our homes warm.

Luke Hansen, Manager of Gas Supply for Northwestern Energy, says they have been watching prices rise.

Hansen says it all adds up to higher prices.

Hansen says despite that, they anticipate that customers won’t see much of a price hike this winter.

Hansen says Northwestern has some gas supply in storage with the rest of the winter supply under firm contract prices.

Natural gas is now about four sixty a therm, down about fifty percent from a year ago.
