Tapteal Substation - Operational 115 kV Electrical Substation in the United States

Tapteal Substation is an operational electrical substation located in the United States, with coordinates 46.236482, -119.276490. The facility operates at a voltage of 115 kV, placing it in the medium-to-high voltage range typical for sub-transmission and distribution substations that serve industrial, commercial, and residential loads. The substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC), which enforce reliability standards for the bulk power system. As a 115 kV facility, it is likely part of a regional transmission or sub-transmission network, connecting higher-voltage transmission lines to lower-voltage distribution systems. The infrastructure may include modern switchgear and automation systems compliant with IEC 61850 standards for substation communication and control. Tapteal Substation contributes to the electrical infrastructure of its region by stepping down voltage for local distribution, supporting grid reliability and power quality. Its operational status ensures continued service to the surrounding area, which may include urban or industrial zones. The facility's location and voltage level are critical for maintaining stable electricity supply and integrating renewable energy sources where applicable.

The substation's location in the United States, likely in an arid or semi-arid region given the coordinates near the Columbia River basin, may involve environmental considerations such as wildfire risk, which can affect overhead transmission lines and substation equipment. The 115 kV voltage level indicates moderate infrastructure that requires clearance and insulation to prevent flashovers. Urban or rural siting influences land use and potential electromagnetic field exposure, though modern designs mitigate such impacts.
