SCHEDULE 3 - DISTRIBUTED ENERGY RESOURCES INTERCONNECTION PROCESS When this screen is being applied to a DER that serves some station service load, only the net injection into the Area EP be considered as part of the aggregate generation. The Area EPS Operator will not consider as part of the aggregate generation for purposes of this screen DER capacity known to be already reflected in the minimum load data. 4.4.2.Voltage and Power Quality Screen In aggregate with existing generation on the line section the following conditions shall be met for the screen to be passed: The voltage regulation on the line section can be maintained in compliance with relevant requirements under all system conditions. The voltage fluctuation is within acceptable limits as defined by Institute of Electrical and Electronics Engineers (IEEE) Standard 1453, or utility practice similar to IEEE Standard 1453. The harmonic levels meet IEEE Standard 519 limits. 4.4.3.Safety and Reliability Screen The location of the proposed DER and the aggregate generation capacity on the line section do not create impacts to safety or reliability that cannot be adequately addressed without application of the Study Process. The Area EPS Operator shall give due consideration to the following and other factors in determining potential impacts to safety and reliability in applying this screen. Whether the line section has significant minimum loading levels dominated by a small number of customers (e.g., several large commercial customers). Whether the loading along the line section is uniform or even. Whether the proposed DER is located in close proximity to the substation (i.e., less than 2.5 electrical circuit miles), and whether the line section from the substation to the Point of Common Coupling is a main line rated for normal and emergency ampacity. 9 198
