Harrisburg North Substation is an operational electrical substation located in Harrisburg, Illinois, United States. Owned by Ameren, a major utility in the Midwest, this facility is part of the transmission and distribution network that serves the surrounding area. As a substation, it transforms voltage levels to facilitate efficient power delivery from high-voltage transmission lines to lower-voltage distribution networks. Operating under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC), the substation adheres to reliability standards that ensure grid stability and security. The substation's location in southern Illinois places it within a region that supports both urban and rural electricity needs. Its operational status contributes to the resilience of the local grid, enabling reliable power supply to residential, commercial, and industrial customers in the area.

The substation is situated in a region with a mix of agricultural and forested land, typical of southern Illinois.
