Overview
Ayersville Substation is an operational electrical substation in Ohio, United States, owned by Toledo Edison. It operates at a voltage of 138 kV, serving as a key node in the regional transmission grid.
Ayersville Substation is an operational electrical substation located in Ohio, United States. Owned by Toledo Edison, a subsidiary of FirstEnergy, the facility plays a role in the regional power transmission network. The substation operates at a voltage of 138 kV, which is typical for sub-transmission and distribution-level infrastructure in the United States. As part of the U.S. electrical grid, Ayersville Substation is subject to reliability standards set by the North American Electric Reliability Corporation (NERC) and regulated by the Federal Energy Regulatory Commission (FERC). The facility's 138 kV voltage level indicates it likely connects local distribution systems to higher-voltage transmission lines, ensuring stable power delivery to surrounding communities. Substations of this scale are critical for grid stability and load balancing. The substation's location in northwestern Ohio places it within a region served by the PJM Interconnection, one of the largest regional transmission organizations in the U.S. Its operational status ensures continued support for local electricity demand, contributing to the resilience of the regional grid. The facility's age and specific equipment details are not publicly available, but typical substations of this type undergo regular maintenance to comply with NERC standards.
Environmental context
The substation is situated in a rural area of Ohio, where agricultural land and small communities dominate the landscape. Electrical infrastructure in such settings must balance reliability with environmental considerations, such as minimizing land use and avoiding sensitive habitats. The 138 kV voltage level suggests moderate electromagnetic field exposure, which is managed through standard siting practices. The facility's operation aligns with regional grid requirements, supporting local energy needs without significant environmental disruption.
Frequently asked questions
