Haystack Substation - 345 kV Operational Substation in the United States

Haystack Substation is an operational electrical substation located in the United States, with coordinates 42.230242, -97.214412. It operates at a voltage of 345 kV, placing it in the high-voltage transmission category, which is critical for long-distance power transfer and grid interconnection. 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. As a 345 kV facility, it is part of the extra-high-voltage network that ensures stable electricity supply across regions. This substation's location in a rural area of the United States supports the regional grid by stepping down voltage for distribution or interconnecting transmission lines. Its operational status ensures continued reliability for local communities and industries, contributing to the overall resilience of the electrical infrastructure.

The substation is situated in a rural area of the United States, where the surrounding environment includes agricultural land and natural habitats. High-voltage substations like this one are typically designed with minimal visual impact and incorporate measures to prevent oil spills and electromagnetic interference. The 345 kV voltage level indicates significant power handling capacity, which supports grid stability and reduces the need for additional generation capacity.
