Natural Gas Industry
The Commission, through its Energy Division, monitors and evaluates regulatory and policy initiatives affecting the natural gas industry, as well as reviews and analyzes regulatory proceedings initiated by Indiana’s natural gas utilities. These proceedings can be complex, sometimes taking 12-18 months to complete. These proceedings include, but are not limited to, rate changes (including gas cost adjustment costs and general rate changes), financing, alternative regulatory plans, service area matters, and conservation initiatives, as well as customer assistance programs. The Research, Policy, and Planning Division provides research and technical support to the Energy Division and the Commission, focusing on federal and state policy and legislation that may impact Indiana utilities and ratepayers.
