Electrical Substation Design and Distribution

University of Illinois

Urbana-Champaign, Illinois

 

The project included the design and installation of two 69/138KV to 15KV outdoor substations located on the University of Illinois at Urbana-Champaign campus.  The project created a campus-wide distribution system that eliminated multiple utility services and created a single 69KV utility interconnection.  The system is capable of distributing up to 80MW of on-site generation directly to the campus loads, creating a self-sufficient electrical system.  The scope of work included 22,000 feet of underground ductlines and manholes, 42,000 feet of 138KV XLPE underground cable, substation and power transformer installation; and six 15KV metal clad switchgear lineups.  Utility interconnection, protective relaying and a system-wide electrical SCADA system were also included.  

Henneman Engineering provided a complete package of design and construction services, including preparation of contract documents for construction and purchase of equipment, construction administration, field observation throughout construction, and scheduling of delivery/installation of substation equipment.
