Rockdale Substation is an operational electrical substation located in Wisconsin, United States. Owned and operated by American Transmission Company (ATC), it is a critical component of the regional high-voltage transmission network. The substation handles voltages of 345 kV and 138 kV, indicating its role in both bulk power transmission and sub-transmission distribution. As part of ATC's infrastructure, Rockdale Substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC). These standards ensure grid reliability and security, with compliance to NERC's Critical Infrastructure Protection (CIP) standards. The substation likely employs modern automation and protection systems, such as those based on IEC 61850, to enhance operational efficiency and grid stability. The substation's location in Wisconsin places it within the Midcontinent Independent System Operator (MISO) market, which coordinates regional electricity dispatch and planning. Its dual voltage levels suggest it interconnects major transmission lines and serves local distribution networks, supporting industrial, commercial, and residential loads in the area. The facility's operational status underscores its ongoing contribution to grid resilience and energy delivery in the region.
Environmental context
Rockdale Substation is situated in a rural area of Wisconsin, characterized by agricultural land and scattered residential developments.
