Yonah Dam Substation - 115 kV Substation in Georgia, United States

Yonah Dam Substation is a 115 kV electrical substation located near the Yonah Dam in Georgia, United States. Owned and operated by Georgia Power, a major utility in the Southeast, this facility is part of the regional transmission network that distributes electricity from hydroelectric generation to local communities. As a 115 kV substation, Yonah Dam operates at a standard sub-transmission voltage level common in the United States. It is subject to NERC reliability standards and FERC regulations, ensuring grid stability and compliance with mandatory reliability requirements. The substation likely includes switchgear and transformers typical for voltage transformation and distribution. The substation's location near a hydroelectric dam underscores its role in integrating renewable energy into the grid. By stepping down voltage from generation levels, it facilitates efficient power delivery to industrial, commercial, and residential customers in northeastern Georgia. Its operational status ensures continued support for the local energy infrastructure.

Located in a rural area of northeastern Georgia, the substation is near the Tugaloo River and Lake Yonah, which support diverse aquatic ecosystems. The facility's operation involves minimal direct environmental impact, but its role in transmitting hydroelectric power contributes to regional renewable energy goals. Standard mitigation measures for substations include oil containment for transformers and vegetation management to prevent outages.
