Overview
Liddell Substation is an operational electrical substation in the United States, operated by OEC with a voltage of 138 kV, serving the local grid.
Liddell Substation is an operational electrical substation located in the United States, near coordinates 35.225211, -97.397301. Operated by OEC, this facility operates at a voltage of 138 kV, placing it in the medium-to-high voltage range typical for distribution and sub-transmission substations. The substation plays a key role in stepping down power from transmission lines to lower voltages for local distribution. 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 138 kV facility, it is subject to NERC's Critical Infrastructure Protection (CIP) standards, ensuring cybersecurity and physical security. The equipment likely includes circuit breakers, transformers, and switchgear compliant with IEEE and ANSI standards. Environmentally, the substation is situated in a region with a temperate climate, and its operation involves minimal direct emissions. However, its role in the grid supports the integration of renewable energy sources and enhances grid stability for the surrounding communities. The facility's location in the United States ensures adherence to stringent environmental regulations, including those from the Environmental Protection Agency (EPA) regarding oil containment and SF6 gas management.
Environmental context
The substation is located in a region with a temperate climate, typical of the central United States. Its operation involves managing electrical equipment that may contain insulating oils and SF6 gas, which are regulated under EPA guidelines for containment and leakage prevention. The facility's role in the grid supports local energy distribution, potentially integrating renewable sources and reducing transmission losses.
