Overview
Armstrong-Marietta Substation is an operational electrical substation in the United States. It operates at a voltage of 69 kV, serving grid stability in the region.
Armstrong-Marietta Substation is an operational electrical substation located in the United States, with coordinates 40.060322, -76.584971. As a substation, it plays a critical role in the electrical infrastructure by stepping down transmission voltages for local distribution. The facility operates at a voltage of 69 kV, which is typical for sub-transmission or distribution-level substations. The substation operates under the regulatory framework of the United States, which includes NERC reliability standards and FERC oversight for transmission-level assets. While 69 kV is below the typical threshold for NERC registration, the facility still adheres to industry standards for safety and reliability. The region's electrical grid is part of the larger interconnection managed by regional transmission organizations. This substation contributes to the local grid's stability and reliability, serving residential, commercial, and industrial customers in the area. Its operational status ensures continued power distribution, supporting community energy needs. The facility's location in Pennsylvania places it within a region with diverse energy generation sources, including natural gas, nuclear, and renewables.
Environmental context
The substation is located in a region with a temperate climate, where seasonal weather variations can impact grid operations. The surrounding area is a mix of agricultural and suburban land uses. Electrical infrastructure like this substation is designed to withstand local environmental conditions, including potential ice storms and heat waves, which can affect line sag and equipment performance. The facility's voltage level of 69 kV is typical for distribution networks that serve local communities with minimal environmental footprint.
Frequently asked questions
Armstrong-Marietta Substation is located in the United States, with coordinates 40.060322, -76.584971. It is situated in a region served by the Pennsylvania electrical grid.
Armstrong-Marietta Substation operates at a voltage of 69 kV, which is typical for sub-transmission or distribution-level substations in the United States.
Armstrong-Marietta Substation is currently operational, meaning it is actively involved in the transmission and distribution of electrical power.
In the United States, substations are subject to NERC reliability standards for transmission assets, though facilities at 69 kV may fall under distribution-level regulations. FERC oversees interstate electricity transmission, and local public utility commissions regulate distribution.
A 69 kV substation typically steps down higher transmission voltages to lower distribution voltages for local use. It also provides switching and protection functions to maintain grid stability and reliability.
