Overview
Gray Summit Substation is an operational electrical substation in Missouri, United States, operating at 138 kV. It plays a role in regional grid stability and power distribution.
Gray Summit Substation is an operational electrical substation located in Missouri, United States. The facility operates at a voltage of 138 kV, which is typical for sub-transmission and distribution-level infrastructure, serving to step down power from higher voltage transmission lines for local distribution. As a substation in the United States, Gray Summit Substation operates under the regulatory framework established by the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC). These bodies enforce reliability standards and oversee the interstate transmission of electricity. The facility's voltage level places it within the medium-voltage range, commonly used for regional power distribution to industrial, commercial, and residential customers. The substation's location in Missouri contributes to the state's electrical infrastructure, supporting grid reliability and power delivery to surrounding communities. Substations like Gray Summit are critical nodes in the power grid, enabling voltage transformation and switching operations that maintain system stability and supply continuity.
Environmental context
The substation is situated in a rural area of Missouri, where the surrounding landscape includes mixed agricultural and forested land. Electrical infrastructure in such settings typically has a localized environmental footprint, primarily related to land use for equipment and access roads. The 138 kV voltage level indicates moderate electromagnetic field emissions, which are managed through standard siting and shielding practices.
Frequently asked questions
Gray Summit Substation is located in Missouri, United States, at coordinates 38.499188, -90.879783.
Gray Summit Substation operates at a voltage of 138 kV, which is a common sub-transmission voltage level in the United States.
Electrical substations in the United States are regulated by the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC), which enforce reliability standards and oversee interstate electricity transmission.
A 138 kV substation typically steps down high-voltage transmission power for regional distribution, serving industrial, commercial, and residential customers. It also provides switching and protection functions to maintain grid stability.
Environmental considerations for substations include land use, electromagnetic field management, noise from transformers, and stormwater runoff. Siting and design practices aim to minimize these impacts.
