Island Green Substation - 115 kV Operational Substation in the United States

Island Green Substation is an operational electrical substation located in the United States, with coordinates 33.659242, -79.052061. Operating at a voltage of 115 kV, it is classified as a transmission-level substation, which is typical for medium-scale infrastructure supporting local grid connectivity. The substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC), ensuring compliance with reliability standards for transmission assets. The 115 kV voltage level indicates its role in subtransmission or distribution, often connecting bulk power systems to local networks. As part of the U.S. electrical infrastructure, Island Green Substation contributes to grid resilience and power delivery in its region.

The substation is located in a region with a temperate climate, where electrical infrastructure must withstand seasonal weather variations. The 115 kV voltage level suggests it is part of the subtransmission network, which typically has lower environmental impact than higher voltage lines but still requires careful siting to avoid sensitive habitats. Substations of this scale often serve mixed-use areas.
