Koch Upriver Substation - Texas Electrical Substation Operated by American Electric Power

Koch Upriver Substation is an operational electrical substation located in Texas, United States. Owned and operated by American Electric Power, a major utility in the region, the facility plays a key role in the local electrical infrastructure. The substation operates at voltage levels of 138 kV and 69 kV, indicating its function in both transmission and distribution networks. As part of the U.S. electrical grid, this substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC). These bodies enforce reliability standards and oversee interstate electricity transmission. The substation's dual voltage levels suggest it serves as a step-down point between high-voltage transmission lines and lower-voltage distribution networks. The substation's location in Texas places it within the Electric Reliability Council of Texas (ERCOT) interconnection, which manages the majority of the state's power grid. Its operational status ensures continued support for regional electricity supply, contributing to grid stability and reliability for surrounding communities.

Located in Texas, the substation operates in a region with a hot climate and high electricity demand, particularly during summer months. The facility's design and maintenance must account for thermal expansion and cooling needs. Its proximity to the Gulf Coast may also require resilience against hurricane-related flooding and storm surges, influencing infrastructure hardening and emergency response protocols.
