224. EXHIBIT ESA PROGRAM AGREEMENT ELECTRIC SYSTEM ANALYSIS SERVICES The City of San Marcos ("Customer") and the Lower Colorado River Authority ("LCRA") have entered into an Agreement for Technical Services dated on or about December 15, 1979. T e Electric System Analysis Services Program Agreement ("Program Agreement') entered into this day of 20CI,-shall become a part of said Agreement for Technical Services as Program Agreement Exhibit E A. With respect to work LCRA agrees to perform for Customer on or after this date, this Program Agreement between Customer and LCRA replaces the original Program Agreement executed April 24, 1995, and the Addendum to Distribution Engineering Contract Services Program Agreement dated January 22, 1997. The original Program Agreement and the Addendum to Distribution Engineering Contract Services Program Agreement shall remain in force and effect with respect to any work LCRA has agreed to perform under them for Customer prior to this date until that work is completed. The Customer and LCRA agree as follows: SERVICE AGREEMENT SCOPE LCRA shall provide the following engineering services to Customer: 1. Verify and/or gather field information needed to construct computer model of primary electric system Size of all primary conductor Location and operation of all switches, capacitors, and reclosers Phase (A B or C) of primary lines and transformers 2. Prepare load-forecast taking into account: Growth in customer meters by rate-class Growth in summer and winter peak demand (kW) Growth in annual energy (kWh) requirements Planning documents available from Customer 3. Evaluate adequacy of existing system utilizing loadflow software Identify overloaded line sections Identify excessive line losses Identify excessive voltage drop Evaluate appropriateness of distribution line equipment 4. Conduct a thorough study of system improvement needs Optimize system to minimize losses Balance phases within circuits Balance load between circuits Evaluate feeder ties between existing circuits Evaluate need for reconductoring Evaluate substation capacity requirements Examine location and operation of load-break switches Examine location and size of capacitor banks for correcting power factor Coordinate construction projects with pole maintenance needs as information is provided by Customer Size and coordinate fuses, reclosers with substation breakers Conduct Contingency Analysis planned or unplanned outage of a distribution feeder, breaker, or power transformer (where applicable) Examine system equipment limits and impacts L O W E R C O L O R A D O R I V E R A U T H O R I T Y
