Proposal No. 2669.01 Water Enterprise Alternative Energy Feasibility Study 1-25 <br />The East Bay Regional Park District (EBRPD) operates 65 regional parks, <br />recreation areas, wilderness, shorelines, preserves and land bank areas <br />in Alameda and Contra Costa Counties. With a strong environmental <br />ethic, the District was Interested in creating a Strategic Energy Plan as a <br />roadmap for future energy decisions. The District contracted NAM to <br />develop a plan to show how the District could significantly Improve its <br />energy efficiency, generate much of its needed energy on site, reduce <br />energy costs, and significantly decrease Its greenhouse gas emissions. <br />Energy use in the parks is concentrated around the structures in each <br />park, some with multiple electric meters. There are 599 structures in <br />the District with a total building area of 851;053 square feet; NAM staff <br />audited 83% of this building area. NAM evaluated the potential to <br />install PV at every park after efficiency measures. Approximately $1.1 <br />million in retrofit energy projects were Identified, Including lighting, <br />controls, HVAC, domestic hot water, and pumping projects. $7,2 <br />million in solar photovoltaic (PV) generation projects have been <br />Identified. NAM evaluated the potential for a RES -BCT solar PV project <br />at one site, which would supply the entire District's PV needs with one <br />system of 1.5 MW. The economic benefit is not as strong when using <br />RES -BCT. However, it was determined that the lower savings are more <br />than made up for by the increased economy of scale in installing one <br />large system Instead of 50 small PV systems over a wide geographic <br />area. Together, the energy efficiency and PV projects are projected to <br />reduce the District's energy bill by 78%. <br />NAM provided implementation assistance for the strategic energy plan <br />by overseeing and tracking EBRPD self -installation of the Identified <br />STRATEGIC ENERGY PIAN <br />1.16 MW RES -BCT Carport <br />system with estimated, <br />REFERENCE: <br />Jeff Rasmussen <br />Assistant Finance Officer <br />East Bay Regional Park District <br />2950 Peralta Oaks Court <br />P.O. Box 5381 <br />Oakland, CA 94605 <br />JRasmussen@ebparks.ora. <br />(510)544-2130 <br />energy efficiency projects and coordinating incentive applications with PG&E for all energy efficiency measures. <br />NAM developed the RFP for solar contractors, assisted the District with proposal evaluations and contract <br />negotiations, and provided technical services to review all solar plan sets and construction documents. NAM also <br />served as the owner's representative for the District throughout the construction of the PV system and assisted <br />the District through the commissioning and utility interconnection processes; <br />NAM is in the process of providing battery storage feasibility analysis to EBRPD. By utilizing NAM's battery <br />storage economic model, EBRPD will be able to identify those meters that benefit from storage solutions. NAM <br />utilizes an algorithm in conjunction with historical 15 minute utility data to simulate and project realistic <br />demand savings. NAM will also provide EBRPD with the most up to date cost information based on actual pricing <br />as seen from recent industry battery proposals. NAM is investigating the impact of state and federal incentive <br />money dedicated to battery storage and will outline the process for securing these Incentives. NAM will deliver a <br />full cash flow analysis that includes the costs, savings, and incentive to help EBRPD identify the viability of <br />battery storage across their largest meters. Upon completion of the feasibility effort, NAM will assist EBRPD with <br />procuring the best storage solution. <br />Copyright © Newcomb Anderson McCormick 2017 <br />25A-39 <br />CITY OF SANTA ANA <br />
