3.0 PROJECT INFORMATION 3.1 Project Location The proposed Project is located within Hennepin County, Minnesota. Figure 1 shows an overview of the general vicinity of the Project and the Proposed Route is shown in Figure 2. Appendix B includes detailed maps of the proposed Project and the planned replacement of the existing Orono Substation described in this Application. The Project is located wholly within the municipal boundaries of the City of Orono within Township 118N, Range 23W, Sections 29, 30 and 32. 3.2 Project Proposal Xcel Energy proposes to replace the existing 69 kV Orono Substation with a new 115-13.8 kV transmission substation and connect the new substation to existing Xcel Energy 115 kV transmission Line 0831 by constructing a new double circuit 115 kV transmission line. The proposed new 115 kV double circuit transmission line primarily runs north and west from the Orono Substation site to transmission Line 0831. Figure 2 and Figure B-2 in Appendix B show the Proposed Route. Appendix B also includes detailed maps concerning environmental factors of the proposed Project. More specifically, Xcel Energy proposes the following for the Project: • install approximately 2,041 feet of new double circuit 115 kV transmission line and structures from the new Orono Substation to the connection point with existing 115 kV transmission Line 0831 at new transmission Structure 076-1; • remove three existing transmission structures (Structures 076, 077, and 078) and associated 1,030 feet of single circuit 115 kV transmission Line 0831 and installing two new structures and approximately 1,095 feet of single circuit 115 kV transmission line to re-route the existing line off of residential property and onto adjacent Huntington Farm Association ("HFA")' property adjacent to the BNSF railroad; • disconnect the existing Line 0831 at transmission Structure 077, install a new double circuit corner structure, and connect the new double circuit 115 kV transmission line from the new Orono Substation to Line 0831; • installing fiber optic ground wire with the new 115 kV transmission line and the replaced segment of Line 0831; • except for existing switchgear (which will be reused in the new substation), remove the existing Orono Substation and construct the replacement Orono Substation as a 115- 13.8 kV transmission substation to accommodate the new 115 kV line termination and/or ring bus by, installing a 28 MVA, 118-14.3 kV transformer, adding transfer trip 1 HFA is an association of landowners which are a part of the Huntington Farm residential development that is located west of the existing Orono Substation site. HFA owns undeveloped parcels surrounding the residential parcels that are Dart of HFA. Orono Project June 7, 2011 MPUC Docket No. E002/TL-11-223 9
