Technical Project Description <br />The City of Santa Ana (City) currently purchases 18 million kilowatt hours (kWh) of <br />electricity each year to operate water well pumps and booster pumps to deliver potable <br />water to its customers. In February 2019, the City approved a "Water Systems Alternative <br />Energy Feasibility Study" ("NAM Study") prepared by Newcomb Anderson McCormick <br />(NAM), a Willdan Company (Appendix B). This Study included an evaluation of installing on - <br />site renewable energy systems to offset some of the City's electrical load, lower electric <br />bills, and reduce the associated greenhouse gas (GHG) emissions. The renewable energy <br />resources that were evaluated included installing solar photovoltaic (PV) modules at six <br />locations, including the Garthe and West pump station/reservoir facilities. <br />Preliminary designs were undertaken to determine the anticipated rate tariff, total system <br />size, annual performance projections, and relative load offset for each. The designs were <br />simulated using HelioScope, an industry standard PV simulation program that uses a local <br />weather data file and calculates the hourly performance of the system based on the angle <br />of insolation, air temperature, wind speed, intensity of clouds, etc. The hourly PV output is <br />subtracted from the hourly electric load profile data from SCE to determine the hourly <br />2 <br />PREVIEW Date: Nov 03, 2021 Workspace ID: WS00800354 Funding Opportunity Number: R22AS00023 <br />
