Hollandale Substation - Operational Substation in Mississippi, USA

Hollandale Substation is an operational electrical substation located in Hollandale, Mississippi, United States. Owned and operated by Entergy Mississippi, this facility plays a key role in the regional power distribution network. The substation handles primary voltage of 115 kV and secondary voltage of 13.86 kV, typical for a medium-voltage substation serving rural and semi-urban areas. As part of the U.S. electrical infrastructure, Hollandale Substation operates under the regulatory oversight of the Federal Energy Regulatory Commission (FERC) and adheres to North American Electric Reliability Corporation (NERC) reliability standards. These standards ensure grid stability and security, particularly for transmission-level assets. The substation's equipment likely includes circuit breakers, transformers, and switchgear compliant with IEEE and ANSI standards. The substation serves the Hollandale community and surrounding areas in Washington County, Mississippi. Its location in the Mississippi Delta region, an area prone to extreme weather events like thunderstorms and hurricanes, underscores the importance of robust infrastructure for maintaining reliable power supply. Entergy Mississippi's ownership ensures integration with the broader Entergy transmission network, supporting both residential and industrial customers.

Located in the Mississippi Delta, Hollandale Substation operates in a region with flat topography and agricultural land use. The area experiences a humid subtropical climate with frequent thunderstorms and occasional hurricanes, which can pose risks to electrical infrastructure. The substation's design likely includes measures for flood resilience and storm hardening to maintain grid stability. Its rural setting reduces direct environmental impact compared to urban substations, but vegetation management and oil containment from transformers are standard practices to protect local ecosystems.
