Overview
Green Country Substation is an operational electrical substation in Oklahoma, United States, owned and operated by Public Service Company of Oklahoma. It operates at 345 kV, a high voltage level critical for regional grid stability.
Green Country Substation is a high-voltage electrical substation located in Oklahoma, United States. Owned and operated by Public Service Company of Oklahoma, the facility operates at 345 kV, placing it in the high-voltage transmission category. This voltage level is typical for bulk power transfer across the regional grid, connecting generation sources to load centers. 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 transmission assets. As a 345 kV facility, it is subject to NERC's Critical Infrastructure Protection (CIP) standards and FERC's rate and reliability oversight. The equipment likely includes modern switchgear and automation systems compliant with IEC 61850 for substation automation. Green Country Substation plays a key role in the electrical infrastructure of Oklahoma, supporting the state's energy needs. Its location in a region with diverse energy resources, including natural gas and wind power, makes it integral to integrating renewable energy and maintaining grid reliability. The substation serves both urban and rural areas, contributing to the resilience of the local power system.
Environmental context
The substation is situated in a region with a mix of urban and rural landscapes, where electrical infrastructure must balance reliability with environmental considerations. High-voltage lines and substations can impact local ecosystems through electromagnetic fields and land use, but modern designs minimize these effects. The facility's operation supports the integration of renewable energy sources, such as wind power from the surrounding plains, which reduces carbon emissions compared to fossil fuel generation.
Frequently asked questions
