Common use of Phase I Clause in Contracts

Phase I. In Phase I, the project will be connected as a tap to the Transmission Owner’s 230kV transmission line MWP-2 via one 230kV circuit breaker in series with one of two ring bus breakers for stuck breaker protection (one in each direction) and a tie-line breaker, as shown on the one-line diagram labeled EL-E-IA-01 attached to this Appendix A as Figure 1. The changes to the existing MWP-2 line protection for this arrangement are described in Phase I System Upgrades in Section II of this Appendix A. Civil/Site work: The Developer will provide site civil work including drainage, finish grade and stone the site. Drainage from the switchyard will be promoted by sloping the base layer below the crushed stone at the site with a minimum slope of 0.5 percent to provide adequate drainage and prevent the accumulation of standing water. The switchyard area shall be covered with a 6 inch layer of 0.75 inch crushed stone and will extend for a distance equal to 5 feet beyond the fence line. Disturbed areas which will not receive stone will be mulched and seeded. Site work, grading, fencing and drainage will be mostly completed during Phase I construction, since the foundations and site work associated with Phase II are completed during Phase I construction. Foundations: Foundations will be designed in accordance with generally accepted practices of soil mechanics. Foundation works will be completed during Phase I, including Phase II equipment foundations for the second incoming A-Frame structure and two additional breakers. Grounding: The substation yard is L-shaped with the outer leg dimensions of the ground grid of 338 feet by 507 feet which includes the area 5 feet outside the perimeter fence. Substation grounding grid resistance shall be designed to be less than 5 ohms per IEEE-80, measured without external ground and without the grounding grid of the Large Generating Facility connected. In addition, the 230 kV Control Building shall be furnished with a special high frequency grounding system for the protection of electronic equipment from transient electrical noises as recommended by IEEE 1100. The below grade grounding system installed in Phase I includes the ground grid and ground wire tails for the Phase II work. The grounding work associated with Phase II is the above grade connections to Phase II equipment.
