Job No. 2669.01 EE�I' y Ern IftE� ri 'UVEv DM.IIEI li' y F:::E�asibflity Study shift accordingly. The City of Santa Ana Climate Action Plan from 2015 indicates that the goal for municipal operations is a CO2e reduction of 30% by the year 2020 and 40% by 2035, relative to the 2008 baseline. It is recommended that the City consider investment in these projects to help achieve the GHG goals, while saving money over the life of the project. The summary table shows the effective cost per kWh at which electricity is being saved. Some of the savings are valued at less than the City currently pays for the electricity due to reasons described in this report. These include anticipated new SCE rates that will shift summer on peak hours later, so little solar power will be generated when it is most highly valued. In other cases where there is not a large existing load (such as SA-3 and SA-6) the power must be wheeled to other meters, which lowers its value. Substituting NEMA wheeling of this power for RES-BCT (described in the report) is a way to significantly increase the value of the electricity for these sites, but SCE would need to approve the arrangement. 1. The Total Installed Cost for the turbine projects includes the anticipated construction contract (labor, materials, tax, overhead and profit), contingency, engineering, and project management, minus a potential incentive for SA-1. See Appendix G. 2. The Total Installed Cost for the solar projects includes the anticipated construction contract, contingency, engineering, project management, and an upfront payment for a performance guarantee. The life cycle numbers include an annual maintenance agreement as well. See Appendix H. 3. The economic analysis assumes that electric rates will escalate at 3.5% per year and that the PV performance will degrade at 0.5% per year. The Net Present Value is calculated with a Discount Rate of 3%. See Appendix H.
