Overview
Holly Hills Substation is an operational electrical substation in the United States, owned and operated by PowerSouth Energy Cooperative. It operates at 115 kV, serving grid stability in the region.
Holly Hills Substation is an operational electrical substation located in the United States, specifically at coordinates 33.641036, -86.118008. Owned and operated by PowerSouth Energy Cooperative, this facility is part of the regional transmission and distribution network, stepping down high-voltage electricity for local distribution. The substation operates at a voltage level of 115 kV, which is typical for sub-transmission or distribution substations in the United States. As a 115 kV facility, it plays a role in the bulk power system, connecting transmission lines to lower-voltage distribution networks. The infrastructure is subject to NERC reliability standards and FERC regulations, ensuring grid stability and compliance with mandatory reliability requirements. This substation serves the surrounding community by providing reliable electrical supply, supporting residential, commercial, and industrial loads. Its operational status and integration into PowerSouth's network contribute to the overall resilience of the regional grid. The facility's location in the southeastern United States places it within a region with growing energy demand, highlighting its importance in maintaining service continuity.
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 mixed urban and rural land uses, with potential impacts from vegetation management and stormwater runoff. As an electrical infrastructure facility, its environmental footprint is primarily related to land use, electromagnetic fields, and the use of insulating oils, which are managed under environmental regulations.
