1 <br /> 1 <br /> configuration to a vertical configuration at the new double circuit Structure 076-1 and the <br /> connection to the new Orono Substation. <br /> 4.5 Design Options to Accommodate Future Transmission Lines , <br /> The proposed double circuit 115 kV transmission line is designed to meet current and projected <br /> needs. In addition, the proposed replacement of the Orono Substation will be designed and <br /> constructed for accommodating future transmission line interconnections. The proposed new <br /> substation will include one new 115 kV, 2000A, group-operated, bus tie disconnect switch to <br /> minimize outages when a second future, transformer is installed. It will also provide a low profile <br /> layout to accommodate two transformers and four switchgear enclosures and space for a future 13.8 <br /> kV bus-tie connection between the distribution transformers. The proposed conductor for the <br /> Project is 795 kcmil 26/7 ACSS which will allow for future reconductor of Line 0831. <br /> I <br /> I <br /> Orono Project June 7,2011 <br /> MPUC Docket No. E002/TL-11-223 20 <br />
