Overview
Rison Substation is an operational electrical substation in Rison, Arkansas, owned and operated by Entergy Arkansas. It handles voltages of 115 kV and 13.86 kV, serving the local grid.
Rison Substation is an operational electrical substation located in Rison, Arkansas, United States. Owned and operated by Entergy Arkansas, it is a key node in the regional power distribution network, stepping down transmission voltage for local distribution. The substation operates at two voltage levels: 115 kV for transmission and 13.86 kV for distribution, typical of a medium-voltage substation serving rural and suburban areas. As part of Entergy Arkansas's infrastructure, it falls under the regulatory oversight of the Federal Energy Regulatory Commission (FERC) and must comply with North American Electric Reliability Corporation (NERC) reliability standards for grid stability. Located in a rural area of Cleveland County, the substation supports residential and agricultural electricity needs. Its role in the Entergy Arkansas system contributes to the reliability of the regional grid, particularly during peak demand or severe weather events common in the southern United States.
Environmental context
The substation is situated in a rural area of Arkansas, where the surrounding landscape includes farmland and forests. Electrical infrastructure in such settings typically has minimal direct environmental impact, though vegetation management and stormwater runoff are considerations. The substation's voltage levels indicate it is a critical link for local power distribution, supporting community resilience.
