As winter approaches, energy prices in Nebraska and South Dakota appear stable, but consumers could still see higher bills if the weather is colder than last year.

Northwestern Energy officials say the price of natural gas remains significantly lower than it has been, so consumers will be able to expect lower utility bills if this winter is mild.

But if more normal winter temperatures return this year, then utility customers will use more energy and see higher bills than last year.

Northwestern’s Bobbi Schroeppel says the utility encourage customers to make their homes as efficient as possible to help reduce their utility bills.

Homeowners are encouraged to install programmable thermostats and add caulk around doors and windows to seal air leaks. Upgrading windows and doors can also reduce energy use.
