Overview
Rolke Road Substation is an operational electrical substation in the United States, owned and operated by Entergy. It operates at a voltage of 138 kV, serving the local grid.
Rolke Road Substation is an operational electrical substation located in the United States, owned and operated by Entergy, a major utility company. The substation operates at a voltage of 138 kV, which is typical for sub-transmission and distribution-level infrastructure, supporting regional grid stability and power distribution. As part of the U.S. electrical infrastructure, Rolke Road 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 transmission-level assets, ensuring the substation meets operational and safety requirements. The 138 kV voltage level places it in the medium-to-high voltage range, commonly used for industrial and urban power supply. The substation plays a key role in the local electrical grid, contributing to reliable power delivery in its service area. Its location in the southern United States, a region with growing energy demand, underscores its importance in maintaining grid resilience and supporting community and industrial electricity needs.
Environmental context
The substation is located in a region with a humid subtropical climate, which can affect equipment performance and maintenance schedules. The surrounding area includes both urban and rural zones, influencing the substation's role in balancing load and ensuring grid stability. The 138 kV voltage level indicates its function in distributing power from transmission lines to local distribution networks, with potential environmental considerations related to electromagnetic fields and land use.
