17 <br /> Electric Vehicle Transition Plan&Charging Infrastructure Evaluation for County Fleet RFQ 367-005463 <br /> Price Proposal December 23,2025 <br /> In this task, ICF will also evaluate a variety of options for EV charging infrastructure implementation and <br /> conduct a comprehensive cost estimate of EV charging equipment and installation. Cost components to be <br /> factored into the analysis can be split into capital, and operating costs. Key capital costs include the <br /> following: <br /> • Charging infrastructure hardware (materials cost) and installation • Software <br /> • Distribution grid equipment and infrastructure upgrades • Make-ready costs <br /> Operating costs are also critical to determining the business case of deploying EV charging infrastructure <br /> and include the following: <br /> • Cost of electricity based on rate tariffs used • Demand charges <br /> • Charger networking costs • Charger data contract costs <br /> All capital and operating costs are crucial factors in determining the business case of charging <br /> infrastructure. ICF will estimate capital costs across each infrastructure development scenario, as well as <br /> the ranges of possible operating costs associated with each scenario. ICF will also develop cost estimates <br /> by location for each phase of infrastructure implementation across the entire charging infrastructure <br /> development timeline. This timeline shall align with and stays ahead of the purchase of replacement ZEV <br /> that will park at each location. <br /> A key factor that can influence the incentives and grants available to the County is whether the installed <br /> chargers are accessible to the public. ICF will outline the pros and cons of making certain chargers publicly <br /> accessible in exchange for substantial incentive funding, which can often cover the full installation cost. <br /> Additionally, we will identify incentives available to the County even without public access to chargers, <br /> though these opportunities are less common and more competitive. Importantly, we will also provide a cost <br /> assessment for the maintenance of EV chargers over the fleet's lifetime. <br /> Having worked with over 100 municipalities across the country on their electrification plans, ICF brings a <br /> wealth of experience in implementing best practices for sharing the costs of EV infrastructure across <br /> departments. We will leverage successful strategies from various municipalities to ensure equitable cost <br /> distribution while streamlining the procurement and installation process. <br /> Utility-side Electrical Infrastructure Assessment: Once the team has determined the number, types, <br /> output power levels, and locations of chargers to be deployed, we will review the capacity of the County's <br /> facilities to support the projected additional electrical load from charging EVs and identify potential site-level <br /> and distribution grid impacts of that additional load. To identify potential utility distribution electrical <br /> infrastructure impacts, our team will first coordinate with Duke Energy & Piedmont Electric Coop to review <br /> data that they already have on the capacity of existing distribution grid infrastructure. Our existing <br /> relationship with Duke Energy and experience working with coops like Piedmont Electric will help <br /> streamline the data collection process to answer the following questions: <br /> • How large is the electrical service from the utility for each relevant facility? <br /> • How much electrical current is each facility consuming at existing peak power demand levels? <br /> • How much electrical capacity is remaining on the utility-side of the meter at existing peak power <br /> demand? <br /> • How much electrical capacity remains on the County's facility side of the meter? <br /> Responses to these questions will help us gather the needed data to conduct the electrical capacity <br /> analysis at each facility and to determine any potential impacts to the electric grid.
