Who is involved in the regulatory process?
CenterPoint Energy's utilities are regulated by state agencies. The commission agencies in both states are the governing bodies over utility services that approve all rates and tariffs. CenterPoint Energy cannot adjust its rates without approval from these agencies. These agencies work to maximize efficiency for the benefit of all parties. CenterPoint Energy in Indiana is regulated by the Indiana Utility Regulatory Commission (IURC) while CenterPoint Energy in Ohio is regulated by the Public Utilities Commission of Ohio (PUCO).
Both states also have a consumer advocate agency that acts to protect consumer rights. In Indiana this agency is the Indiana Office of the Utility Consumers' Counsel (OUCC) and in Ohio it is the State of Ohio Office of Consumers' Counselor.
Federal Regulatory Agencies include the Federal Energy Regulatory Commission (FERC) and the Department of Transportation (DOT). FERC regulates interstate natural gas pipelines and electric transmission lines. The DOT is the regulator for the Federal Pipeline Safety Act that establishes safe operating practices for pipelines.
