Overview
Poly Substation is an operational electrical substation in the United States, owned and operated by Entergy. It operates at voltages of 69 kV and 4.16 kV, serving the local grid.
Poly Substation is an operational electrical substation located in the United States, owned and operated by Entergy, a major utility company. The substation plays a key role in the regional power distribution network, stepping down transmission voltages for local use. The substation operates at two voltage levels: 69 kV for transmission and 4.16 kV for distribution, indicating its function as a step-down substation. As part of the Entergy system, it is subject to North American Electric Reliability Corporation (NERC) reliability standards and Federal Energy Regulatory Commission (FERC) regulation for grid stability and security. Poly Substation contributes to the electrical infrastructure serving the surrounding community, ensuring reliable power delivery. Its operational status and integration into Entergy's network highlight its importance in maintaining grid resilience and supporting local industrial and residential electricity needs.
Environmental context
The substation is located in a region with a humid subtropical climate, which can pose challenges such as heat and storm-related stress on electrical equipment. Its urban or suburban setting likely requires careful management of electromagnetic fields and noise to minimize community impact. The facility's age and technology level influence its environmental footprint, with modern substations incorporating SF6-free switchgear and other eco-friendly practices.
