State Mill Substation - 69 kV Electrical Substation in the United States

State Mill Substation is an electrical substation located in the United States, operated by Minnkota Power Cooperative. The facility is operational and plays a role in the regional power transmission network, stepping down voltage for local distribution. 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, it falls under the regulatory oversight of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC), ensuring reliability and compliance with standards. This facility contributes to the stability and reliability of the local power supply, serving communities in its service area. Its operation supports the broader electrical infrastructure of the region, facilitating the delivery of electricity from generation sources to end users.

The substation is located in a rural area of the United States, where electrical infrastructure supports agricultural and residential loads. The 69 kV voltage level indicates a distribution or sub-transmission role, with potential environmental considerations related to electromagnetic fields and land use. The facility's operation is subject to environmental regulations that manage impacts on local ecosystems and communities.
