Common use of Interconnection Description Clause in Contracts

Interconnection Description. The Mainesburg 345/115 kV project is a new 345 to 115 kV substation in the northeast region of the Penelec service territory. The Project is a mandatory PJM Interconnection, L.L.C. (“PJM”) baseline Regional Transmission Expansion Plan (“RTEP”) upgrade that was presented at the September 7, 2011 PJM Transmission Expansion Advisory Committee (“TEAC”) meeting and was assigned baseline RTEP upgrade ID b1608. Baseline upgrade ID b1608 includes the construction of Mainesburg 345/115 kV substation connecting to the Xxxxx City – Watercure Road 345 kV and Xxxxxx Drive – Mansfield 115 kV line. PJM also identified the need to install two (2) 345 kV capacitors at Mainesburg substation at the November 3, 2011 TEAC meeting and assigned baseline RTEP upgrade ID b1802. The Project loops the Xxxxx City – Watercure Road 345 kV line and the Xxxxxx Drive – Mansfield portion of the East Xxxxxxx – Farmers Valley 115 kV line into Mainesburg substation which consists of a 345/115 kV transformer and ring bus on the 115 kV and 345 kV. The project will connect to the NYISO system on the NYSEG Xxxxx City – Watercure Road 345 kV line approximately 151.8 miles from Xxxxx City substation and approximately 25.2 miles from NYSEG’s Watercure Road substation. The point of change of ownership and point of interconnection (as set forth in Figure 1 of Appendix A) is where the NYSEG owned transmission line attaches to the TrAILCo owned Mainesburg substation dead-end structure. The project will connect to the Penelec system on the Penelec Xxxxxx Drive – Mansfield 115 kV line approximately 8.5 miles from Xxxxxx Drive substation and 5.6 miles from Mansfield substation.
