Overview
4B Roslyn Substation is an operational electrical substation in the United States, operating at 138 kV. It plays a role in regional grid stability and power distribution.
4B Roslyn Substation is an operational electrical substation located in the United States, with coordinates 40.783811, -73.643947. The facility operates at a voltage of 138 kV, classifying it as a high-voltage substation critical for transmission and distribution within the regional grid. As a substation operating at 138 kV, 4B Roslyn Substation is subject to North American Electric Reliability Corporation (NERC) reliability standards and Federal Energy Regulatory Commission (FERC) regulations for transmission-level assets. The facility likely employs modern switchgear and automation systems compliant with ISO/IEC 61850 standards to ensure safe and efficient power flow. The substation's location in the northeastern United States places it within a densely populated and industrially active region, where reliable electrical infrastructure is essential for residential, commercial, and industrial consumers. Its operational status contributes to grid resilience and supports local energy demand.
Environmental context
The substation is situated in a suburban area of New York, where electrical infrastructure must balance reliability with environmental considerations such as electromagnetic field management and land use. The facility's 138 kV operation requires careful siting to minimize visual and ecological impact, while its role in power distribution supports regional energy efficiency.
