Overview
Grey Iron Substation is an operational electrical substation in Michigan, United States, operated by ITC. It operates at a voltage of 138 kV, serving as a key node in the regional transmission grid.
Grey Iron Substation is an operational electrical substation located in Michigan, United States. Operated by ITC, the facility is part of the high-voltage transmission network, with a voltage level of 138 kV, which is typical for sub-transmission and distribution interconnection in North America. 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 and oversee interstate electricity transmission. ITC, as a transmission-only utility, focuses on maintaining grid stability and ensuring compliance with these standards. The facility's voltage level places it in the medium-to-high voltage range, supporting local distribution and industrial loads. As part of the Michigan grid, Grey Iron Substation contributes to the reliable delivery of electricity to surrounding communities and industries. Its role in voltage regulation and power flow management is critical for maintaining system stability, especially given the region's seasonal demand variations and integration of renewable energy sources.
Environmental context
The substation is located in an urbanized area of Michigan, where electrical infrastructure must balance reliability with environmental considerations such as electromagnetic field management and stormwater runoff. Typical substations in this region incorporate oil-filled equipment with containment measures to prevent soil and water contamination. The surrounding area's industrial and residential mix influences the substation's operational requirements and environmental compliance.
