Parallel System Sample Clauses

Parallel System. In a Parallel System, a Generator is connected to a bus common with the APS System, and a transfer of power between the two systems is a direct result. A consequence of such interconnected operation is that Customer’s Generator must be considered in the electrical protection and operation of the APS System. A Parallel System encompasses any type of Generator or GF (including ES systems) that can electrically parallel with, or potentially back-feed the APS System. This includes any GF using a Closed Transition Transfer Switch or Transfer Scheme as well as any Static Inverter that can be configured or programmed to operate in a “utility interactive” mode. APS has specific interconnection, inspection and contractual requirements, as outlined in this document that must be complied with and information that needs to be submitted for all interconnected generators. These requirements include a “visible open” Disconnect Switch meeting certain requirements to isolate Customer’s System from the APS System, as well as protective relaying, metering, special rate schedules, and other safety and information requirements. Customer will be responsible for having the GF protective schemes tested by a qualified testing/calibration company. APS personnel will inspect the system and Customer will be required to sign an Interconnect Agreement and, if applicable, an Electric Supply/Purchase Agreement with APS. In certain instances, APS and Customer will need to sign a “Non-Parallel Connection Agreement” and/or an “Operating Agreement”. APS will advise Customer of requirements after reviewing the proposed design. APS does not extend “blanket approval” to any specific type of Generator or generation scheme since each project is site specific and needs to be reviewed on a case-by-case basis. In addition to the various other requirements specified in this document, Parallel Systems shall specifically comply with the technical requirements outlined in the Interconnection Technical Requirements (Section 8) of this document.
