Sunman Substation - 69 kV Electrical Substation in Indiana, United States

Sunman Substation is an operational electrical substation located in Indiana, United States. Owned and operated by Hoosier Energy, a generation and transmission cooperative, this facility plays a role in the regional power distribution network. The substation operates at a voltage of 69 kV, which is typical for sub-transmission or distribution-level infrastructure. As part of the U.S. electrical grid, Sunman Substation operates under the regulatory framework established by the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC). These bodies enforce reliability standards for bulk power systems, ensuring stable and secure electricity delivery. The 69 kV voltage level indicates this substation likely serves as a distribution substation, stepping down power from higher transmission voltages for local use. The substation's location in rural Indiana supports the electrical needs of the surrounding community, including residential, agricultural, and small industrial customers. Its operational status ensures continued grid stability and power supply to the area. Hoosier Energy's cooperative model emphasizes member-owned, reliable electricity service.

The substation is situated in a rural area of Indiana, where the landscape is predominantly agricultural. Electrical infrastructure in such settings typically has a low environmental footprint, with minimal land use and no emissions during operation. The 69 kV voltage level suggests the substation is part of the distribution network, which generally has lower environmental impact compared to high-voltage transmission lines. Local wildlife and vegetation are unlikely to be significantly affected by the substation's presence.
