Coopers Corners Substation | NYSEG Electrical Substation in New York, USA

Coopers Corners Substation is an operational electrical substation located in New York, United States, and operated by NYSEG. The facility handles multiple voltage levels including 345 kV, 115 kV, and 34.5 kV, indicating its role in both high-voltage transmission and sub-transmission distribution. As part of the New York grid, it supports the state's diverse energy mix and population centers. 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 for the bulk power system. NYSEG, a subsidiary of Avangrid, manages this asset as part of its extensive network serving upstate New York. The 345 kV voltage level classifies it as a major transmission substation, critical for long-distance power transfer and grid stability. Environmental and operational significance includes its role in integrating renewable energy sources such as wind and solar from upstate New York into the grid. The substation's location in Sullivan County, a region with growing renewable capacity, makes it a key asset for clean energy transmission. Its operational status ensures continued reliability for residential, commercial, and industrial customers in the area.

The substation is located in a rural area of Sullivan County, New York, characterized by forests and agricultural land. Its operation supports the integration of renewable energy from upstate wind and solar farms into the regional grid, reducing reliance on fossil fuels. The high-voltage infrastructure minimizes transmission losses over long distances, contributing to overall grid efficiency.
