INTERCONNECTION FACILITIES STUDY AGREEMENT,ATTACHMENT C <br /> LODI ENERGY CENTER <br /> 7.1 Steady State Power Flow Analysis <br /> Power Flow analysis will be performed using the two base cases <br /> described in Section 6. These base cases will be used to simulate <br /> the impact of the Project during normal operating conditions as well <br /> as during single (CAISO Category"B") and selected multiple <br /> (CAISO Category"C") contingency conditions. The study will cover <br /> the transmission facilities within PG&E's Sacramento, Sierra, <br /> Stockton, and Stanislaus planning areas. <br /> The single (CAISO Category"B") and selected multiple (CAISO <br /> Category"C")contingencies include the following outages: <br /> 7.1.1 CAISO Category°B" <br /> • All single generator outages within the study area. <br /> • All single (60-230 kV)transmission circuit outages <br /> within the study area. <br /> • All single (60-230 kV)transformer outages within the <br /> study area. <br /> • Overlapping single generator and transmission circuit <br /> outages for the transmission lines and generators within <br /> the study area. <br /> 7.1.2 CAISO Category i1C" <br /> • Selected bus (60-230 kV) outages within the study area. <br /> • Selected outages caused by selected breaker failures <br /> (excluding bus tie and sectionalizing breakers) at the <br /> same above bus section. <br /> • Selected combination of any two-generator/transmission <br /> line/transformer outages (except ones included above in <br /> Category"B")within the study area. <br /> • Selected outages of double circuit tower lines (60-230 <br /> kV)within the study area. <br /> 7.2 Short Circuit Duty Analysis <br /> Short circuit studies will be performed to determine the maximum <br /> fault currents on various buses in the vicinity of the Project. This <br /> ISIS will assess the impact of increased fault duty resulting from the <br /> added generation. Equipment that may become overstressed as a <br /> result of increased fault duty will be identified. <br /> 7 <br />
