Overview
Card Substation, operated by Eversource, is an operational electrical substation in the United States. It handles voltages of 345 kV, 115 kV, and 69 kV, serving the regional grid.
Card Substation is an operational electrical substation located in the United States, operated by Eversource, a major utility in the Northeast. The facility handles multiple voltage levels including 345 kV, 115 kV, and 69 kV, indicating its role in both high-voltage transmission and sub-transmission distribution. As part of the interconnected grid, it contributes to the reliability of electricity supply in the region. The substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC), which enforce reliability standards for bulk power systems. The 345 kV voltage level classifies it as a transmission asset critical for long-distance power transfer and grid stability. The presence of multiple voltage levels suggests it serves as a key node for voltage transformation and distribution to local networks. Environmental and operational significance of Card Substation lies in its support for the regional grid, particularly in the context of New England's energy landscape. Eversource's infrastructure plays a vital role in integrating renewable energy sources and maintaining supply during peak demand. The substation's location and voltage capacity make it an essential component for ensuring reliable electricity to residential, commercial, and industrial customers in the area.
Environmental context
The substation is located in a region with a mix of urban and rural areas, typical of Connecticut. Its operation involves managing high-voltage electricity, which requires careful planning to minimize electromagnetic field impacts and ensure safety. The facility's age and technology are consistent with standard substation designs, and its role in the grid helps support local energy needs while adhering to environmental regulations.
