Tarentum Substation is an electrical substation located in Tarentum, Pennsylvania, United States. Owned and operated by West Penn Power, the facility is part of the regional electrical infrastructure supporting the distribution of electricity. The substation operates at a voltage of 34.5 kV, which is typical for distribution-level substations that step down transmission voltages for local use. As a substation in the United States, Tarentum Substation operates under the regulatory framework established by the Federal Energy Regulatory Commission (FERC) and adheres to reliability standards set by the North American Electric Reliability Corporation (NERC). These standards ensure grid stability and safety. The facility's voltage level places it in the medium-voltage category, commonly used for distributing power to industrial, commercial, and residential customers. The substation plays a key role in the local electrical grid, providing reliable power to the Tarentum area and surrounding communities. Its operational status and connection to the broader transmission network contribute to the resilience of the regional power supply. West Penn Power, a subsidiary of FirstEnergy, operates a network of substations and lines across Pennsylvania, supporting energy needs in the region.

The substation is located in Tarentum, a borough along the Allegheny River in western Pennsylvania. The area has a mix of residential, commercial, and light industrial land uses. Electrical substations like this one have localized environmental impacts, including electromagnetic fields and potential for oil spills from transformers. However, modern substations are designed with containment measures and are subject to environmental regulations. The site's proximity to the river requires careful management to prevent runoff and protect water quality.
