Healthcare Campus Substation and Power Distribution

The campus power distribution upgrades involved the replacement of two 12.47 kV utility feeders with new single 138 kV feeder and generator. The new distribution system included 10 MVA, 138 – 12.47 kV substation and two 2250 kW stand-by diesel generators designed for closed transition switching to generation for peak shaving in parallel with the utility.

Electrical design services also included converting overhead to underground wiring; new feeders to the main hospital; and 12.47kV underground distribution to campus buildings (medical offices, residential care facility, and rehabilitation center).

Electrical Distribution Assessment included:

Survey of loads and projection of future loads to size main transformer and generators.

Sighting of the substation to minimize visibility.

Verification of existing underground lines routing.
