o A port to space ratio of 1 port for every 4-5 spaces provides the best use of parking.
2.3. Recommendations on charging capacity (L2, DCFC, V2G, etc.) and the variables assessed at each site to determine best charging level solution(s) and recommended size of installation o L2: Level 2 are 6.6kW and fairly easy to install with little to no upgrades required to the current electrical infrastructure. o DCFC: Direct Current Fast Charging range from 50kW- 200kW however they are expensive and would require a significant and potentially costly upgrade to the power infrastructure. o V2G: Vehicle to Grid allows for car batteries to give back to the grid but does require the use of smart meters and must be used on a large scale basis in coordination with power companies o Casco Contractors recommends using 5-10 Level 2 ports at each site. 2.4 Deployment phasing and timelines for installation at various site types and with various charger types. o Casco Contractors can develop a phasing and timeline plan in coordination with the City of San Diego while also maximizing funding opportunities and determine the ideal charger types for each location. 2.5. Variables and determinates in scaling EVSE charging stations/capacity in locations after initial deployment. o Electrical service capacity is the biggest challenge to installing EV. Each site must be evaluated and coordinated with the respective power company to determine the feasibility of EVSE charging stations. 2.6 Permits/permit costs, easements and/or utility coordination in respect to site information, design, engineering, and all other aspects of installation and interconnection.
