22 Job No. 2669.01 Water Systems Alternative Energy Feasibility Study <br />SECTION 7: <br />POTENTIAL FOR SOLAR POWER GENERATION AT PUMP <br />STATIONS AND CITY YARD <br />There are several city -owned and operated locations that have the potential for the addition of solar PV. These <br />sites include Garthe station, South station, West station, East station, Cambridge station, and the City Yard. The <br />following table lists the existing conditions of these locations. <br />�& ite Na <br />MAL <br />Garthe Station <br />Annual kWh Usage <br />- <br />1,530,219 <br />Existing Rate <br />Schedule <br />TOU-PA-3-13 <br />South Station <br />77,362 <br />TOU-PA-2-13 <br />West Station <br />2,861,684 <br />TOU-8-13 <br />East Station <br />802,416 <br />TOU-PA-3-A <br />Cambridge Station <br />526,805 <br />TOU-PA-3-13 <br />City Yard <br />884,323 <br />TOU-GS-3-B <br />After completing site -walks to get a close inspection of solar installation potential, preliminary designs were <br />made to determine the anticipated rate tariff, total system size, annual performance projections, and relative <br />load off -set for each site. A summary of this information can be seen in the following table. <br />Name <br />Garthe Station <br />AnticipatedSite <br />Rate Tariff <br />TOU-PA-3-E <br />Solar <br />stem Generation <br />500 <br />(kWh) <br />894,325 <br />... <br />Off -Set (%) <br />58% <br />South Station <br />TOU-PA-2-D <br />44 <br />75,170 <br />97% <br />West Station <br />TOU-8-E <br />230 <br />422,617 <br />15% <br />East Station <br />TOU-PA-3-E <br />220 <br />393,985 <br />49% <br />Cambridge Station <br />TOU-PA-3-D <br />100 <br />184,480 <br />35% <br />City Yard <br />TOU-GS-3-D <br />523 1 <br />869,805 <br />98% <br />Each project would be interconnected to the local electric utility (SCE) through their Net Energy Metering (NEM) <br />program. NEM allows systems to export to the grid during times when the site load is less than the solar PV <br />generation, receiving a credit worth nearly the full retail rate of the energy being exported. The NEM policy does <br />not allow for systems to be installed that would generate more than the site's annual load. <br />It is assumed that the water tank sites would utilize either a ballasted mounting system, or a direct attachment, <br />as there are different types of roofs on the reservoirs. <br />An example of a solar system installed atop a municipal water reservoir is shown here from West Sacramento. <br />(This photograph is from the Sunworks website.) <br />CITY OF SANTA ANA Newcomb I Anderson I McCormick <br />PREVIEW Date: Nov 03, 2021 Workspace ID: WS00800354 Funding Opportunity Number: R22AS00023 <br />
