If you think your heating bill is high now, just wait.
Duke Energy is asking for a huge rate increase for natural gas customers, and at lest one group is not happy about it.
The Ohio Consumers council says the total increase, if approved, could top $500 million over the next several years.
The group also says the base rate for customers, which is now $6, would nearly triple to $15.
Duke Energy says they need the cash for safety issues, like replacing old natural gas lines.
