Loudoun County Supervisor Juli Briskman recently inquired about the infrastructure requirements for data centers, specifically whether each facility necessitates two substations. During a discussion, an unnamed expert clarified that in many data center projects, high-voltage lines typically at 230 kV feed into a switching substation, which then supplies a distribution substation.

While technically two distinct entities, these switching and distribution substations are often co-located, appearing as a single facility. They frequently abut each other and may even share a fence and overall footprint to efficiently manage the intense energy demands inherent in modern data center operations.
