UR New South Substation and Phase I Distribution System

The University of Rochester campus includes more than 200 acres, over 100 buildings, and a medical center that includes Strong Memorial Hospital. The campus electrical distribution system had grown substantially over the years and included a large central cogeneration plant. Due to the expanding nature of the campus, it was necessary to provide a new source of supply from the utility company to accommodate the load growth. This project created a new 75 MVA, 115/11.5kV South Substation and a Phase I Distribution System to serve the campus. The design included the following:

  • Detailed system modeling, including load flow analysis and short circuit analysis
  • Over two miles of underground concrete encased 12-way and 16-way ductbank design; this included extensive field survey and coordination with existing utilities on the campus as well as permitting for crossing of town-owned roadways and a NYSDOT bridge
  • Ductbank design including spare conduits for future extension of circuits to the River Campus (Future Phase 2)
  • Electrical building at the new substation to house the 11.5kV main distribution switchgear
  • Replacement of existing Mid-Campus Chiller Plant switchgear
  • Replacement of South Campus switchgear
  • Replacement of 11.5kV Loop switches
  • Protection coordination study and relay settings

Before starting the project, CHA provided a comprehensive study and master plan for the campus electrical distribution system. This study included investigation, alternatives of system modeling, and analyses required to develop a plan for the campus distribution system. This study was completed in 2012 and was the basis of design for the design and construction phases of the project.
