Fernald Substation - Operational ITC Substation in the United States

Fernald Substation is an operational electrical substation located in the United States, owned and operated by ITC. The facility handles transmission-level voltages of 161 kV and 69 kV, positioning it as a medium-voltage substation critical for regional power distribution. The substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC), which set reliability standards for the bulk power system. As part of ITC's network, it likely incorporates modern automation and protection systems compliant with industry standards such as ISO/IEC 61850 for substation automation. Fernald Substation plays a key role in maintaining grid stability and reliability in its service area. Its location in Iowa supports the integration of local generation sources and ensures efficient power delivery to residential, commercial, and industrial customers. The facility's operational status contributes to the resilience of the regional electrical infrastructure.

The substation is situated in a rural area of Iowa, where agricultural land use dominates. Electrical infrastructure in such settings must balance reliability with minimal environmental footprint, often through careful siting and use of insulated equipment to reduce wildlife interactions. The moderate voltage levels (69-161 kV) indicate a focus on local distribution rather than long-distance transmission, reducing landscape impact.
