SECTION 7: POTENTIAL FOR SOLAR POWER GENERATION AT PUMPSTATIONS & CITY YARD 23 In the case of the City Yard, a series of carports would be used to reach the desired solar PV output. Note, the designs compiled in this proposal are preliminary, and are not intended for construction; a structural engineer would need to evaluate the site specifics for each design to ensure the safety and security of the systems. During the site walk, some trees were identified as allowable for removal, while others, such as those on adjacent properties, were not allowed to be removed; the preliminary designs have accounted for this information. After evaluating the site's load and solar PV potential, examining the current and expected future rate tariff, the NAM team was able to calculate the financial benefit of these projects, independently and as a portfolio. Although a simple loan and a power purchase agreement were both evaluated, for the purposes of this summary report, the NAM team has focused on the results of the cash -purchase option, since it is the most financially advantageous. The following table shows the sites under consideration for PV, the current and recommended SCE rate schedule to provide the lowest rate with solar power, the size of the proposed system in DC kW (based on the nominal DC rating of the proposed solar modules, and the anticipated construction cost per DC Watt of system capacity. The cost per Watt varies according to the size of the system and the complexity of installation, with a higher cost for parking lot shade structures because of the extra construction materials involved.
