New York ? Natural gas prices tumbled again Thursday, hitting new seven-year lows as the country pares down on energy usage and more unused supply is put into storage.

That will mean huge savings for a lot of people this winter when the heating bill arrives.

On Monday, Spokane, Wash.-based utility Avista Corp. said it wants to reduce natural gas prices for its Oregon customers to the lowest levels in five years. And in the Midwest, Alliant Energy Corp. and Wisconsin Public Service Corp. both predicted heating bills would drop around 20 percent.

“Any savings we get, they get,” Alliant spokesman Scott Drzycimski said.
