Millwood Substation - High-Voltage Electrical Substation in the United States

Millwood Substation is an operational electrical substation located in the United States, with coordinates 41.192647, -73.800423. It operates at high voltage levels of 345 kV and 138 kV, indicating its role in both transmission and sub-transmission networks. This facility is part of the broader North American power grid, which is regulated by NERC reliability standards and FERC oversight for interstate electricity transmission. The substation's voltage levels suggest it connects major transmission lines (345 kV) with lower-voltage distribution networks (138 kV), typical of a bulk power substation. In the United States, such facilities are critical for grid stability and are subject to stringent reliability standards under NERC's Critical Infrastructure Protection (CIP) requirements. The substation likely includes modern switchgear and automation systems compliant with IEC 61850 standards for substation communication. Located in a region with coordinates near Westchester County, New York, Millwood Substation supports the electrical infrastructure for a densely populated area. Its operational status ensures reliable power delivery to residential, commercial, and industrial customers. The facility's role in voltage transformation and grid interconnection is essential for maintaining system stability and meeting peak demand in the region.

The substation is situated in a temperate climate zone with seasonal variations that influence electricity demand for heating and cooling. Its location in a suburban area near New York City means it supports a high-density load center, requiring robust infrastructure to minimize outages. The surrounding environment includes mixed residential and natural areas, so the substation's design likely incorporates measures to mitigate visual and noise impacts, such as low-profile equipment and landscaping.
