That's the recommendation from the Illinois Commerce Commission.
Nicor wanted to bump up bills by 9%, about a $7 monthly increase for customers.
The commission says that's too steep.
It will vote on the rate hike next month.
Nicor would raise rates by $204 million, rather than the $314 million the company proposed.
Opponents say a new increase would be Nicor's fifth in eight years.
While a significant reduction, the recommendation falls short of the $153 million in cuts proposed by consumer advocates and the Office of the Illinois Attorney General, opponents said.
