NYAB has two substations feeding their Watertown facility. The primary substation is a 115kV yard with 2 substation transformers. Each sub transformer takes the voltage down to 13.2kV. A dedicated 13.2kV aerial circuit then runs about a mile to a second 13.2:480V substation yard. 480V then handles the primary utilization voltage for the facility. This project included a study that evaluated redundancy at both substations. Recommendations included:
