SCHEDULE 3 - DISTRIBUTED ENERGY RESOURCES INTERCONNECTION PROCESS <br />Using the table below, determine the type of interconnection to a primary <br />distribution line. This screen includes a review of the type of electrical service <br />provided to the Interconnecting Customer, including line configuration and the <br />transformer connection to limit the potential for creating over-voltages on the <br />er system due to a loss of ground during the <br />operating time of any anti-islanding function. <br /> <br />Primary Distribution Type of Interconnection to <br />Results <br />Line Type Primary Distribution Line <br />Three-Phase, three wire Three-phase or single-phase, <br />Pass Screen <br />phase-to-phase <br />Three-phase, four wire Effectively-grounded three-phase <br />Pass Screen <br />or single-phase, line-to-neutral <br /> <br />If the proposed DER is to be interconnected on single-phase shared secondary, <br />the aggregate generation capacity on the shared secondary, including the <br />proposed DER, shall not exceed 20 kW or 65% of the transformer nameplate <br />rating. <br /> <br />If the proposed DER is single-phase and is to be interconnected on a center tap <br />neutral of a 240-volt service, its addition shall not create an imbalance between <br />the two sides of the 240-volt service of more than 20% of the nameplate rating <br />of the service transformer. <br />The technical screens listed shall not preclude the Area EPS Operator from using tools <br />that perform screening functions using different methodologies given the analysis is <br />aimed at preventing the voltage, thermal and protection limitations as the listed <br />screen. <br /> <br />3.3.Notification of Approval of Application <br />Provided the Simplified Interconnection Application passes the initial screens, or if the <br />proposed interconnection fails the screens but the Area EPS Operator determines that <br />the DER may never the less be interconnected consistent with safety, reliability and <br />power quality standards, the Area EPS Operator shall provide notice to the <br />Interconnection Customer that their Simplified Interconnection Application has been <br />approved. <br /> <br />3.4.Failure of Review Screens <br />If the proposed interconnection fails the screens the Interconnection Customer will be <br />notified by the Area EPS Operator that the Simplified Interconnection Application has <br />4 <br /> <br />179 <br />
