Hartfield Substation - 115 kV Operational Substation in the United States

Hartfield Substation is an operational electrical substation located in the United States, with coordinates 42.261576, -79.468921. The facility operates at a voltage level of 115 kV, classifying it as a medium-voltage substation that typically serves distribution or sub-transmission functions within the electrical grid. As a substation in the United States, Hartfield Substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC). These standards ensure reliability and security of the bulk power system. The 115 kV voltage level is common for sub-transmission networks that connect distribution systems to higher-voltage transmission lines. The substation's location in a rural or semi-rural area of New York State suggests it may serve local communities and industries, contributing to grid resilience and power quality. Its operational status indicates ongoing maintenance and compliance with NERC reliability standards, supporting the broader electrical infrastructure in the region.

The substation is situated in a region with a temperate climate, where seasonal weather variations can impact grid operations. The 115 kV voltage level indicates it is part of the sub-transmission network, which is critical for distributing power from high-voltage transmission lines to local distribution systems. The facility's location in a rural area may reduce exposure to urban-related risks but requires robust design to withstand winter storms and ice accumulation.
