Northern Indiana Public Service Co. says it's committed to improving its operations.
The Office of Utility Consumer Counselor is recommending approval of a $125 million dollar rate increase.
Jim Atterholt previously served in the position for four years under Gov. Mitch Daniels.
If approved, customers would see a gradual rate increase averaging 0.75 percent each year from 2017 to 2022.
The plan would upgrade Duke Energy's infrastructure around the state at an estimated cost of one percent per year for ratepayers.
The change is meant to help customers transition to the addition of the 930 area code in southern Indiana.
The Indianapolis area code is expected to run out of telephone numbers by 2017.
Legislators say the state needs a new energy program that is 'pro-ratepayer.'
The report says Indiana’s energy efficiency programs provide a benefit to the state, and will continue to do so in the next several years.
The Indiana Utility Regulatory Commission recently allowed Duke Energy to pass the costs of building its Edwardsport plant on to its customers.
