Granville Substation - High-Voltage Electrical Substation in the United States

Granville Substation is an operational electrical substation located in the United States, owned and operated by American Transmission Company. The facility handles high-voltage transmission at 345 kV and 138 kV, indicating its role in the bulk power system. As part of the American Transmission Company's network, it supports the regional grid's reliability and capacity. The substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC), which enforce standards for transmission-level assets. The dual voltage levels suggest it serves as a critical node for stepping down power from extra-high-voltage transmission to sub-transmission or distribution levels. Such substations typically employ modern switchgear and automation systems compliant with ISO/IEC 61850 standards. Granville Substation plays a key role in maintaining grid stability in its area, facilitating the efficient transfer of electricity from generation sources to load centers. Its operational status ensures continued service to communities and industries, contributing to the overall resilience of the U.S. electrical infrastructure. The facility's location in an urban or suburban context underscores its importance for local power distribution and reliability.

The substation's location in the United States places it within a regulatory environment that emphasizes grid reliability and environmental compliance. High-voltage substations like Granville can influence local land use and require careful siting to minimize electromagnetic field impacts. The facility's operation supports the integration of renewable energy sources, reducing reliance on fossil fuels and contributing to lower carbon emissions in the power sector.
