Overview
Sun Substation is an operational electrical substation in Washington-St. Tammany Electric Cooperative's service area, United States. It operates at 69 kV, supporting local grid stability and power distribution.
Sun Substation is an operational electrical substation located in the service territory of Washington-St. Tammany Electric Cooperative in the United States. As a 69 kV substation, it falls within the medium-voltage range typical for distribution-level infrastructure, serving to step down transmission voltages for local distribution networks. The substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC), which set reliability standards for the bulk power system. Washington-St. Tammany Electric Cooperative, a member-owned utility, manages this facility as part of its commitment to reliable electricity delivery in rural and suburban areas of Louisiana. This substation plays a critical role in maintaining grid stability for the cooperative's members, ensuring consistent power supply to residential, commercial, and agricultural customers. Its strategic location supports the region's energy needs, contributing to the overall resilience of the local electrical infrastructure.
Environmental context
The substation is situated in a region characterized by a mix of forested areas and wetlands, typical of southeastern Louisiana. Its operation involves managing voltage levels to minimize electrical losses and ensure efficient power transmission. The facility's design likely incorporates standard environmental safeguards to prevent oil leaks from transformers and to manage electromagnetic fields, aligning with industry best practices for substation siting and operation.
