Developer’s Attachment Facilities. The Large Generating Facility is connected via three 34.5kV collector lines from the turbine fields to the Xxxx substation (“Xxxx Substation”), each line consists of a combination of underground and overhead 34.5 kV circuits. Underground circuits are solid dielectric 34.5 kV power cables direct buried in cable trenches 4 feet deep along newly created turbine access roads. Overhead circuits are jacketed Xxxxxxx type cable of compact design supported from wood structures and mounted on insulated brackets suspended from messenger wire. The overhead circuits are located along established county roads. Fiber optic cables are routed along power with certain physical separation. The Xxxx Substation is an outdoor air insulated low profile design, single bus configuration. The Xxxx Substation will include Developer’s Attachment Facilities, Transmission Owner’s Attachment Facilities, and, ultimately, some System Upgrade Facilities. The Transmission Owner’s Attachment Facilities and System Upgrade Facilities are described in Sections I.B. and II, respectively, of this Appendix A. The Developer’s Attachment Facilities in the Xxxx Substation consist of three 1200A circuit breakers for the collector lines and one 3000A main breaker for connecting the 34.5 kV collector bus to the 34.5/230kV step-up transformer. This breaker is SF6 type, rated 72 kV, 40 kA. The substation circuit breakers, disconnect switches, PTs, CTs, and surge arresters are interconnected together by a combination of strain buses and rigid buses mounted on porcelain insulators, supported on steel structures. The Xxxx Substation 34.5kV system includes circuit breaker current transformers and bus connected voltage transformers for metering and relaying. A 34.5 kV-120/208V station service transformer will supply power for the station service. All equipment, including fences, is grounded to a sub-grade grounding system designed to IEEE 80 requirements. The switchyard area shall be covered with a 6 inch layer of 0.75” crushed stone and will extend for a distance equal to 5 feet beyond the fence line. Grounding Transformer – Each collector line is connected with a grounding transformer at the substation end of the line to prevent line voltage rise between the time when the breaker is tripped and the turbines coast down. The Main Step-up Transformer is an outdoor mineral oil filled, forced air cooled, two winding 34.5/230 kV three phase transformer, rated at 75/92/120 MVA OA/FA/FAA. The transformer shall be c...
Developer’s Attachment Facilities. The Developer’s Attachment Facilities (“DAFs”) include all of the facilities between the Developer’s side of the Point of Change of Ownership (“PCO”) and the Large Generating Facility. As depicted in Figure A-1 to this Appendix A, the DAFs consist of the following major electrical and physical equipment: Three (3) 345 kV feeder cables.
Developer’s Attachment Facilities. “DAF”): The Merchant Transmission Facility shall interconnect at the available bus position of the Connecting Transmission Owner’s West 49th Street 345 kilovolt (“kV”) Gas Insulated Switchgear (“GIS”) substation (“Xxxx 00xx Xxxxxx Substation”) between existing circuit breakers 7 and 8. The DAF, as identified in Figure A-1, will be located between the Xxxx 00xx Xxxxxx Substation and the cable transition splice vault at West 52nd Street. Specifically, the DAF will be a single circuit, three phase, 345kV buried electric cable system comprised of (i) an approximately 1800 foot solid dielectric cable segment installed in the public roadways of New York City from the point at which it exits a cable transition splice vault on West 00xx Xxxxxx to a 345kV GIS design termination in the West 00xx Xxxxxx Substation; and (ii) all necessary terminations, splices and appurtenances as necessary to construct, operate and maintain the DAF. Figure A-1 identifies the DAF, Point of Change of Ownership, and the Point of Interconnection. Technical details of the major DAF equipment are as follows:
Developer’s Attachment Facilities i) General Description: Developer’s Attachment Facilities consist of three (3) 18/355kV Generator Step-Up transformers (“GSU”) that feed from each GSU primary side underground Nexans type, XLPE Solid Dielectric Cable feeders to a collecting ABB type Gas Insulated Switchgear (“GIS”). The GIS has one set of motor operated disconnect switches and motor operated grounding switches for each incoming GSU feeder cable. The GIS has one main outlet feeder (“G13”), which also contains one set of motor operated disconnect switches and motor operated grounding switches. G13 is one three (3) phase feeder, made up of parallel 1,192kcmil Xxxxxxx aerial cable, with a total circuit length of 2,000 feet.
