(Di Generation of Solar Power at Garthe and West Pump Station Facilities Project Bureau of Reclamation Water Energy and Efficiency Grant FY2022 D. Evaluation Criteria D.1. Evaluation Criterion A —Quantifiable Water Savings Describe the amount of estimated water savings. For projects that conserve water, please state the estimated amount of water expected to be conserved (in acre-feet per year) as a direct result of this project. Describe the support/documentation of estimated water savings. This Project will save 101.4 acre feet per year (AFY) of water based on reduced water use for energy production. According to researchers at the Virginia Water Resources Research Center, in Blacksburg, Virginia; fossil -fuel -fired thermoelectric power plants consume more than 132 billion gallons of fresh water per day (2008) in the United States alone, which translates to an average of 25 gallons of water to produce 1 kilowatt-hour (kWh) of electricity. IEEE Spectrum, by Willie Jones, April 1, 2008. The City currently purchases energy from SCE which receives energy from a variety of sources. The main energy generation facilities for SCE are located in SCE's service area of Southern California. Although the City does not provide water directly to SCE power generation facilities, SCE's power generation facilities are located Southern California, which is a region currently experiencing severe impacts to its water supplies due to the ongoing drought. The City cannot guarantee that the Project will result in water savings in City's service area; however, water savings will occur since the Project is shifting the Garthe and West Pump Stations from fossil fuel fired thermoelectric power to solar power, which requires no water in the electricity generation process. Describe current losses Please explain where the water that will be conserved is currently going and how it is being used. Consider the following: a. Explain where current losses are going (e.g., back to the stream, spilled at the end of the ditch, seeping into the ground)? The estimated 101.4 AFY of water is currently being used to generate the energy needed for operation of the water system. b. If known, please explain how current losses are being used. For example, are current losses returning to the system for use by others? Are current losses entering an impaired groundwater table becoming unsuitable for future use? Currently 101.4 AFY of treated water is being used to produce the energy needed to power the Garthe and West Pump Stations. Implementation of the proposed Project could help recover the drinking water currently being used for energy production that could be used for other needs. 4 PREVIEW Date: Nov 03, 2021 Workspace ID: WS00800354 Funding Opportunity Number: R22AS00023
