SOUTH DAKOTA (WNAX)- We have heard the warnings about expected price spikes and possible shortages of natural gas this winter.

Tom Glanzer with Northwestern Energy says he is optimistic that prices and supply will settle down.

Glanzer says Northwestern has contracted for a good portion of its winter supply.

Glanzer says gas suppliers are still working through the Texas freeze up from February.

Some industry analysts expect natural gas prices to be forty to ninety percent higher than last winter.
