Where are transmission substations primarily located?

The primary location of transmission substations is at electrical generating stations because these substations serve as critical points in the electrical grid where high-voltage electricity generated at power plants is transitioned to lower voltages for distribution. These substations are strategically placed close to generating stations to efficiently manage the flow of electricity from the source to the transmission lines that carry it to consumers.

While municipal power plants might have their own substations, they are not the primary location for transmission substations on a larger scale. Residential areas typically do not host transmission substations due to space, safety, and zoning regulations, and industrial zones alone do not exclusively house these substations, as they are part of a network that spans various locations based on the demand and layout of the electrical grid. Thus, the connection to electrical generating stations is essential for the operation and efficiency of the entire power distribution system.
