Overview
North Madison Substation is an operational electrical substation in Wisconsin, United States, owned and operated by American Transmission Company. It handles voltages of 345 kV and 138 kV, serving the regional grid.
North Madison Substation is an operational electrical substation located in Wisconsin, United States. Owned and operated by American Transmission Company, it is a key node in the regional transmission network, handling voltages of 345 kV and 138 kV, which are typical for high-voltage bulk power transmission. The substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC), ensuring reliability and compliance with mandatory standards. As part of the American Transmission Company's portfolio, it contributes to the stability of the Midwest grid, which is interconnected with the Eastern Interconnection. This facility plays a critical role in transmitting electricity from generation sources to distribution networks, supporting the energy needs of surrounding communities. Its location in Wisconsin places it within a region with a mix of urban and rural load centers, and its voltage levels indicate it is a significant hub for long-distance power transfer.
Environmental context
The substation is situated in a region with a temperate climate, where seasonal variations can impact electricity demand and grid operations. Its location in Wisconsin, an area with both agricultural and urban landscapes, means the facility supports diverse load patterns. The high voltage levels (345 kV and 138 kV) suggest it is part of the backbone transmission system, which has a larger physical footprint and potential visual impact compared to lower-voltage distribution substations.
