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 />Orono Project June 7, 2011 <br />MPUC Docket No. E002/TL-11-223 20 <br />
