Overview
Holt Switch Substation is an operational electrical substation in Ohio, United States, owned and operated by Carroll Electric Cooperative. It operates at a voltage of 69 kV, serving the local grid.
Holt Switch Substation is an operational electrical substation located in Ohio, United States. Owned and operated by Carroll Electric Cooperative, the facility plays a key role in the regional power distribution network. With a voltage level of 69 kV, it is classified as a medium-voltage substation, typical for rural cooperative systems. The substation operates under the regulatory framework of the United States, which includes compliance with NERC reliability standards for grid stability and FERC oversight for transmission-level assets. As a cooperative-owned facility, it is subject to state-level utility regulations and cooperative governance. The 69 kV voltage level is common for sub-transmission and distribution substations, linking higher-voltage transmission lines to local distribution networks. Environmentally, the substation is situated in a rural area of Ohio, where it supports agricultural and residential electricity needs. Its operation is critical for maintaining reliable power supply to the surrounding community, and it adheres to standard environmental practices for electrical infrastructure, including oil containment and wildlife protection measures.
Environmental context
The substation is located in a rural area of Ohio, characterized by agricultural land and scattered residential developments. Its 69 kV voltage level indicates a role in distributing power from higher-voltage transmission lines to local consumers. The facility's environmental impact is managed through standard practices such as vegetation management, stormwater runoff controls, and spill prevention for insulating oil. Its location away from densely populated areas reduces noise and visual concerns.
