81st & Yale Tap Substation is an operational electrical substation located in Tulsa, Oklahoma, United States. Owned by Public Service Company of Oklahoma, a subsidiary of American Electric Power, this facility plays a role in the regional transmission and distribution network. The substation operates at a voltage of 138 kV, which is a common sub-transmission level in the US grid, typically serving industrial and large commercial loads. The substation is part of the broader electrical infrastructure in Oklahoma, which is regulated by the Federal Energy Regulatory Commission (FERC) for wholesale electricity markets and by the Oklahoma Corporation Commission for retail service. As a transmission-level asset, it falls under the North American Electric Reliability Corporation (NERC) reliability standards, ensuring grid stability and security. The 138 kV voltage level indicates a medium-to-high capacity facility, often used to step down power from higher voltage transmission lines for local distribution. Operationally, the substation contributes to the reliability of the electric supply in the Tulsa metropolitan area. Its location at the intersection of 81st Street and Yale Avenue places it in a suburban residential and commercial zone, supporting local communities and businesses. The substation's role in the grid is critical for maintaining voltage stability and power quality, especially during peak demand periods.
Environmental context
