♦ Identify viability and available area for energy storage for the site <br />♦ Determine electrical system modifications and upgrades <br />♦ Review potential control technology and communication equipment <br />Task 2 Deliverables <br />♦ Working document outlining the result of the site visit and initial calculations needed for <br />conceptual design and economic analysis <br />1.3 Conceptual Design and Economic Analysis <br />TRC, on behalf of Santa Ana, will develop the site -specific conceptual designs; the engineering <br />staff that conducted the site visits will lead this development. TRC will produce conceptual <br />designs and will review the drawings and any solar PV simulation results with the City of Santa <br />Ana to determine the need for additional scenarios. TRC will produce summary reports for the <br />site. TRC will conduct the following activities under this task: <br />♦ Perform value of resilience (VOR) calculation for inclusion in financial analysis. VOR <br />will inform the decision -making process for deploying a solar -driven microgrid through <br />concrete $/kWh resilience values <br />♦ Optimize system design for the site based on critical load consumption projections, <br />production modeling, and operational assumptions <br />♦ Produce conceptual solar and storage design options for the site <br />♦ Refine system sizing and equipment locations for the site with the City of Santa Ana and <br />other stakeholders <br />♦ Perform economic modeling of the overall project with multiple financing scenarios <br />including cash, grants, leases, bonds, incentive programs (e.g., SGIP), and power <br />purchase agreements as applicable. This will include sensitivity and probability <br />projections. <br />Task 3 Deliverables <br />♦ Site visit to present and review findings <br />♦ In -person or conference call presentation with the City of Santa Ana including draft <br />conceptual design and initial economic analysis <br />1.4 Microgrid Feasibility Report <br />Under this task, TRC will develop a microgrid feasibility report based on the technical and <br />economic analysis that will occur under Tasks 2 and 3. The report will include recommendations <br />for the City of Santa Ana for the development and deployment of the SARTC resilient <br />transportation hub microgrid project. <br />Task 4 Deliverables: <br />Microgrid Feasibility Report that will include analysis results and recommendations <br />
