Overview
GREC #3 Interconnect is a 345 kV substation in Oklahoma, United States, operated by the Grand River Dam Authority. It plays a key role in regional grid stability and power transmission.
GREC #3 Interconnect is a high-voltage substation located in Oklahoma, United States, operated by the Grand River Dam Authority (GRDA). The facility operates at 345 kV, a standard transmission voltage level, indicating its role in bulk power transfer and grid interconnection. As part of the GRDA system, it supports the integration of generation resources and load centers in the region. 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. The 345 kV voltage class is typical for large-scale transmission infrastructure, connecting power plants to major load centers and enabling interstate power flows. The facility's design likely incorporates modern substation automation standards such as IEC 61850 for efficient monitoring and control. Environmentally, the substation's location in northeastern Oklahoma places it within a region with diverse ecosystems, including prairies and woodlands. The facility's operation supports the local grid's reliability and the integration of renewable energy sources, contributing to the region's energy transition. Its role in the GRDA system underscores its importance for community service and industrial power supply.
Environmental context
The substation is situated in a region characterized by mixed prairie and woodland ecosystems. Its operation at 345 kV indicates a significant footprint, but modern substations are designed to minimize environmental impact through compact layouts and oil containment systems. The facility supports grid stability and renewable energy integration, aligning with broader environmental goals.
