Facility Components. The interconnection facility, as a minimum, will consist of a control building, the interrupting and isolating device(s), protective control devices, and data-acquisition equipment. All the above will be enclosed in a fenced yard with restricted access. SPPCo. Standard GI0005T presents the minimum-design specifications for substation interconnection facilities. GI0005T supplements the following requirements: 5.1.1.1 The control building will be temperature controlled and weatherproof to enclose the AC and DC power sources; the relaying devices; and the telemetering, supervisory RTU, and communication equipment. 5.1.1.2 The interrupting device will be a power circuit breaker capable of interrupting maximum available fault current or industry-standard minimum levels, whichever is greater. It shall be connected for SPPCo. supervisory control. If the addition of a line tap and extension to the QF's generation adds any appreciable exposure to the existing transmission/distribution facilities, additional circuit breaker(s) may be required at the tap point to mitigate this exposure. Air-break switches will be installed on each side of the circuit breaker to isolate the breaker for inspection and maintenance purposes. Single-breaker schemes will not include bypass provisions. Where lines terminate on switches, ground blades will be required. 5.1.1.3 The following protective relays will be installed at the interconnection point (minimum requirement). Typical settings required by SPPCo. are defined below. Sierra will
