RULES FOR INTERCONNECTION OF DISTRIBUTED GENERATION FACILITIES (Customer-Owned Generation)

A division of IMPERIAL IRRIGATION DISTRICT

Effective August 15, 2007

Rules for Interconnection of Distributed Generation Facilities (Customer-Owned Generation) ______________________________________________________________________________ A. APPLICABILITY. These Rules describe the distributivegeneration interconnection, operating and metering requirements for a Generating Facility (GF) for interconnection to the Distribution System of Imperial Irrigation District (IID). Subject to the requirements of this Rules, IID shall allow the Interconnection of a GF to its Distribution System. A.1. DEFINITIONS. Capitalized terms used in these Rules, and not defined in other IID Rate Schedules and/orRegulations Governing the Sale and Use of Electric Energy (IID Rates and Regulations), shall have the meaning ascribed to such terms in Section H of these Rules. The definitions set forth in Section H of these Rules shall only apply to these Rules. A.2. CONSISTENT WITH IEEE 1547. These Rules were revised to be consistent with the requirements of ANSI/IEEE11547-2003 Standard for InterconnectingDistributed Resources with Electric Power Systems (IEEE 1547). In some cases, IEEE 1547 language was adopted directly; in others, IEEE 1547 requirements were interpreted. These Rules have been devised to maintain the spirit of both documents. Language from IEEE 1547 that was adopted directly (as opposed to paraphrased language or previous language that was determined to be consistent with IEEE 1547)is followed by a citation that lists the Clause from which the language derived. For example, IEEE 1547-4.1.1 is a reference to Clause 4.1.1. In the event of any conflict between these Rules and any of the standards listed herein, the requirements of ths shall take precedence. B. GENERAL REGULATIONS, RIGHTS AND OBLIGATIONS B.1. OPERATING AUTHORIZATION. Producer must comply with these Rules,execute an Interconnection Agreement with IID, and receive IID’s express written permission before Parallel Operation of its GF with IID’s Distribution System. IID shall apply these Rules in a non-discriminatory manner and shall not unreasonably withhold its permission for Parallel Operation of Producer’s GF with IID’s Distribution System. B.2. SEPARATE AGREEMENTS REQUIRED FOR OTHER SERVICES. Producerrequiring other electric services from IID including, but not limited to, Distribution Service during periods of curtailment or interruption of Producer’s GF, shall enter into agreements with IID for such services in accordance with IID Rates and Regulations.

Rules for Interconnection of Distributed Generation Facilities (Customer-Owned Generation) ______________________________________________________________________________ B.3. SERVICES NOT PROVIDED WITH INTERCONNECTION. Interconnection with IID's Distribution System under these Rules does not provide Producer any right to utilize IID's System for the transmission, distribution, or wheelingof electric power, nor does it limit such right. B.4. COMPLIANCE WITH LAWS, REGULATIONS AND RATE SCHEDULES. Producer shall ascertain and comply with IID Rates & Regulations; applicable Federal Energy Regulatory Commission (FERC) approved regulations; and any local, state or federal law, statute or regulation which applies to the design, sitting, construction, installation, operation, or any otheraspect of Producer’s GF and/or Interconnection Facility. B.5. DESIGN REVIEWS AND INSPECTIONS. IID shall have the right to review the design of Producer's Generating and/or Interconnection Facility to specify the interface of protective relays; to determine feeder reclosing practice; to identify overcurrent coordination; to identify where to make changes to voltage, regulator, capacitors, and...
