LR Cammack Substation - Arkansas Electrical Substation Operated by Entergy Arkansas

LR Cammack Substation is an operational electrical substation located in Arkansas, United States. Owned and operated by Entergy Arkansas, the facility plays a key role in the regional power distribution network. With a voltage level of 115 kV, it is classified as a medium-voltage substation, typical for sub-transmission and distribution applications. The substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC), ensuring compliance with reliability standards for grid stability. Entergy Arkansas, a subsidiary of Entergy Corporation, serves approximately 700,000 customers across the state, and this substation supports the delivery of electricity to residential, commercial, and industrial users. As part of the Entergy Arkansas grid, LR Cammack Substation contributes to the resilience and reliability of the local electrical infrastructure. Its location in central Arkansas places it within a region experiencing steady population growth, making the substation's role in maintaining power quality and availability increasingly significant for community and economic development.

The substation is situated in central Arkansas, a region characterized by a humid subtropical climate with hot summers and mild winters. The local electrical infrastructure must withstand seasonal weather events, including thunderstorms and occasional ice storms, which can affect grid reliability. The 115 kV voltage level indicates a balance between transmission efficiency and local distribution needs, typical for suburban and rural areas. The facility's design likely incorporates standard environmental mitigation measures such as stormwater management and vegetation control to minimize ecological impact.
