Garfield Tap Substation - 138 kV Electrical Substation in the United States

Garfield Tap Substation is an operational electrical substation located in the United States, with coordinates 39.63°N, 77.49°W. The facility operates at a voltage of 138 kV, classifying it as a high-voltage substation that supports transmission-level grid functions. As part of the U.S. electrical infrastructure, it is subject to NERC reliability standards and FERC regulation. The substation's technical specifications indicate a 138 kV voltage level, which is typical for subtransmission or distribution substations that interconnect local grids with higher-voltage transmission lines. In the United States, such facilities are critical for maintaining grid stability and ensuring reliable power delivery to residential, commercial, and industrial consumers. The regulatory framework includes compliance with NERC's Critical Infrastructure Protection (CIP) standards and FERC's oversight of interstate electricity transmission. Environmentally, the substation's location in a rural or suburban area of Maryland (based on coordinates) suggests it serves a mix of load types. Its operational status ensures continued support for local electricity demand, and its voltage level indicates it may serve as a tap point for distributing power from larger transmission lines. The facility's role in the grid underscores its importance for community energy reliability.

The substation is located in a region with moderate population density, likely serving residential and light commercial loads. Its 138 kV voltage level is typical for subtransmission, which can have lower visual and land-use impacts compared to higher-voltage lines. The facility's operation contributes to grid stability, but aging switchgear or lack of modern automation could pose risks. The area's climate includes seasonal temperature variations that may affect equipment performance.
