19 <br /> Electric Vehicle Transition Plan&Charging Infrastructure Evaluation for County Fleet RFQ 367-005463 <br /> Price Proposal December 23,2025 <br /> • Charge Management: Recommending solutions for charge management software and hardware <br /> to maximize the amount of charging done on off-peak rates and reduce peak rate charging costs. <br /> • Permits: Estimating a high-level cost for obtaining any required permits for the installation and <br /> operation of charging stations. <br /> • Labor and Installation: Estimating the labor costs and expenses related to the installation of the <br /> entire charging infrastructure. <br /> • Load Profile: Providing an estimated load profile for the chargers being proposed for each Point- <br /> of-Service based on the projected use in alignment with our proposed vehicle procurement <br /> schedule. <br /> • Vehicle to Grid: Evaluate options for taking advantage of the large network of electric vehicles as <br /> a backup power solution during outages or periods of high-power consumption. <br /> Upon completing the evaluations, the ICF team will compile and consolidate all the associated costs for <br /> each facility that has been assessed. A simplified illustration of our methodology to electrical infrastructure <br /> assessment is shown in Exhibit 6. <br /> Exhibit 6.

Solar power system costs are <br /> generally calculated on a per-watt basis, while battery storage costs are estimated based on the required <br /> kilowatt-hour capacity. This includes a comparison between grid-connected and micro-grid solutions with <br /> microgrids offering much greater security during outages in exchange for a higher cost. <br /> Task 2 Deliverables <br /> • A memo containing charging infrastructure cost assessment, including the required utility upgrades <br /> required to support the fleet, along with an estimate of the eventual transformer capacity needed at <br /> each site.
