Overview
Harmon Substation is an operational electrical substation in the United States, handling voltages of 345 kV, 138 kV, and 69 kV. It plays a key role in regional grid stability and power distribution.
Harmon Substation is an operational electrical substation located in the United States, with coordinates 40.720869, -81.540731. The facility handles multiple voltage levels including 345 kV, 138 kV, and 69 kV, indicating its role in both high-voltage transmission and sub-transmission. As a substation, it serves as a critical node in the electrical grid, stepping down voltage for distribution or interconnecting transmission lines. Operating under the regulatory framework of the United States, Harmon Substation is subject to NERC reliability standards and FERC oversight for transmission-level assets. The 345 kV voltage level classifies it as a high-voltage substation, typically associated with bulk power transmission. The presence of 138 kV and 69 kV suggests it also serves local distribution networks, making it a key facility for both regional and local grid stability. The substation's location in the United States places it within a well-regulated electrical infrastructure system. Its operational status and voltage diversity indicate it is an active component of the grid, contributing to reliable electricity supply. The facility's role in voltage transformation and power routing is essential for maintaining grid resilience and supporting industrial, commercial, and residential loads in the area.
Environmental context
The substation is situated in a region with a temperate climate, typical of the northeastern United States. Its operation involves electromagnetic fields and potential noise from transformers, but modern substations are designed to minimize environmental impact. The facility's voltage levels suggest it is part of a larger transmission network, which can have land-use implications for corridors. However, substations generally have a localized footprint and are subject to environmental regulations regarding oil containment and wildlife protection.
Frequently asked questions
Harmon Substation is located in the United States at coordinates 40.720869, -81.540731. It operates within the US electrical grid.
