Overview
TMI 230 kV Substation is an operational electrical substation in the United States, owned and operated by FirstEnergy. It operates at 230 kV, serving as a key node in the regional transmission grid.
TMI 230 kV Substation is an operational electrical substation located in the United States, owned and operated by FirstEnergy. The facility operates at a voltage level of 230 kV, classifying it as a high-voltage transmission substation that plays a critical role in the regional power grid. The substation's technical specifications indicate a 230 kV voltage level, which is typical for bulk power transmission in the United States. As part of the FirstEnergy network, it is subject to NERC reliability standards and FERC regulation, ensuring grid stability and compliance with mandatory reliability requirements. The facility's location in the Mid-Atlantic region places it within the PJM Interconnection, one of the largest regional transmission organizations in the world. Environmentally, the substation's operation supports the integration of diverse generation sources, including nuclear, natural gas, and renewables, into the grid. Its role in voltage regulation and power flow control is essential for maintaining system reliability and meeting electricity demand in the surrounding communities. The facility's age and condition are typical for infrastructure of this type, with ongoing maintenance and upgrades to ensure continued performance.
Environmental context
The substation is located in a region with a mix of urban and rural areas, where grid stability is critical for residential, commercial, and industrial consumers. The 230 kV voltage level indicates its role in long-distance power transmission, which can help reduce line losses and improve efficiency. The facility's operation is subject to environmental regulations regarding electromagnetic fields, oil containment, and noise, though specific local impacts are managed through standard utility practices.
