Charging Infrastructure Optimization: One of the key features that sets ICF's FleetCHARGE tool apart from other charging infrastructure models in the market is its embedded optimization algorithms. These algorithms enable the City to optimize the number of chargers by increasing the vehicle - to -plug (V21P) ratio while maintaining the resilience of both charging and fleet operations. Following the development of the baseline charging infrastructure needs scenario (assuming 1:1 V2P), FleetCHARGE uses its optimization algorithm to develop an optimized charging infrastructure needs scenario. This involves determining the most appropriate V21P ratio for each groups of vehicles and assessing the feasibility of smart/scheduled charging. This approach implies using fewer charging stations to service a greater number of EVs, leading to significant cost savings. It reduces the upfront investment in charging infrastructure and minimizes ongoing operational and maintenance expenses. Moreover, this efficient use of resources is particularly beneficial in conserving space, a crucial aspect in urban or densely populated areas. The ICF team will carefully review the recommendations provided by its FleetCHARGE tool to identify the highest feasible V21P ratios that can be achieved while ensuring reliability and successful daily operations of the fleet. tatv,R in this scenario, each vehicle is paired with a dedicated charging plug, ensuring that every vehicle has its designated charging port. Optimized V211) Ratio Scenario • Optimized V2P ratio • Multiple vehicles share a port This scenario aims to optimize the number In determining the charging infrastructure needed for each location, the ICF of vehicles capable of sharing a charging team will also plan for future growth and expansion by considering the port. This is accomplished by adjusting the scalabilit of the chosen charging station configurations. Our team will Y g g g ratio a ensure efficient use of infrastructure while sti!l meeting each of infrastructure anticipate the potential increase in the City's EV fleet and ensure the vehicles duty cycle. selected charging stations can accommodate the additional demand. This may involve allocating additional space and electrical capacity for future installations. By proactively considering scalability, the ICF team will ensure the charging infrastructure can easily adapt and scale up to meet the growing needs of the City's EV fleet. Similar to the approach taken in fleet transition planning, the ICF team will also extend its services to provide recommendations for cooperative contract procurement options for charging infrastructure, if available. This includes exploring established contracts with entities such as Sourcewell and Drive EV Fleets, among others, to ensure the City has access to the most efficient and cost-effective charging solutions. Opportunity for Community -Level and Employee Charging: In addition to fleet charging, the ICF team will also evaluate the feasibility of installing publicly accessible community -level charging infrastructure at various facilities (including cities' public parking facilities), an initiative aimed at enhancing EV adoption within communities and for City employees. This process involves a collaborative effort with facility managers to assess the frequency of public vehicle visits and the average dwelling time of these vehicles at the facilities. This information is critical in determining both the number of charging stations required and the appropriate power level for each charger. For instance, in scenarios where vehicles are typically parked for more than 2 hours, such as at parks or libraries, Level 2 chargers would be suitable. These chargers offer a balance between speed and efficiency, making them ideal for longer stays. Moreover, the volume of visiting vehicles and the likelihood of these being EVs will inform the decision on the number of charging stations needed at each facility. However, the mere presence of charging stations may attract additional EV users to these facilities. Therefore, a safety factor will be applied to account for this potential increase in EV traffic. To prioritize City facilities for public and employee charging, the ICF team will develop a scoring rubric to identify the most suitable facilities for charger installation. Through this scoring as well as the assessment described earlier, the ICF team will provide recommendations on the number and type of publicly accessible chargers that eligible facility could consider. Utility -side Electrical Infrastrcture Assessment: Once the team has determined the number, types, output power levels, and locations of chargers (including both fleet and community charging) to be deployed, we will review the capacity of the City's facilities to support the projected additional electrical load from charging EVs and identify Use or disclosure of data contained on this sheet is subject to the restriction on the title page of this proposal 12
