Greenlawn Substation - Operational Electrical Substation in the United States

Greenlawn Substation is an operational electrical substation located in the United States, with coordinates 40.859744, -73.387358. It operates at voltage levels of 138 kV and 69 kV, indicating a medium-to-high voltage facility that serves as a critical node in the local power transmission network. The substation's voltage specifications suggest it likely functions as a step-down or distribution substation, interconnecting high-voltage transmission lines with lower-voltage distribution networks. In the United States, such facilities are subject to NERC reliability standards and FERC regulation, ensuring grid stability and compliance with mandatory reliability requirements. The dual voltage levels also imply the presence of transformers and switchgear typical of substations in this sector. As part of the broader electrical infrastructure, Greenlawn Substation contributes to reliable electricity supply for surrounding communities and industrial users. Its operational status ensures ongoing support for grid resilience, particularly in the context of the Northeastern US grid, which faces challenges such as aging infrastructure and increasing demand. The facility's location in a densely populated region underscores its importance for maintaining power quality and availability.

The substation is located in a suburban area of New York, characterized by mixed residential and commercial land use. Its operation involves electromagnetic fields and potential oil leakage from transformers, which are managed through standard environmental safeguards. The facility's proximity to urban centers means it supports high electricity demand while adhering to local environmental regulations.
