SECTION 6: POTENTIAL FOR HEAD RECOVERY AT MWD CONNECTIONS 21 <br />12 ftahp sec 62.4 lbs 0.746 kW <br />sec x 178 ft x 550 ft lbs x ft3 x 83.5%mech.eff.x 95%elect. eff x hp =143 kW <br />This assumes the same mechanical efficiency as found for the 12 -inch turbine for the 8 CFS flow rate. This <br />turbine is likely to be a 14 or 16 -inch unit. <br />In the case of SA -6, the anticipated full load hours of operation are expected to be 5,915 hours per year, so the <br />anticipated energy generation is 845,901 kWh per year. <br />The monetary value for this electricity based on the RES -BCT arrangement with the Generation portion of TOU- <br />GS-1-LG rate schedule is $55,131 per year. The value of the generated electricity is approximately $0.065 per <br />kWh. <br />Should the City sign up with SCE through the NEMA program, the electricity would be worth approximately <br />$0.145 per kWh, more than double the RES -BCT savings. The City would need to enter discussions with SCE and <br />possibly apply for an interconnection to determine which rate will apply to this project. <br />The projected cost to purchase and install the new hydro -turbine is $1,072,174. This involves the purchase of <br />the new turbine generator set with electrical panel and controls, the construction of a new vault below the <br />sidewalk to house the turbine and switchgear, the connection with SCE including a new transformer to accept <br />the power, and integration with the existing SCADA controls. <br />Newcomb I Anderson I McCormick 19H-29 CITY OF SANTA ANA <br />
