Matrix Consulting Group 1 October 21, 2025 Electric Vehicle (EV) Charging Fee Analysis The City of Redwood City contracted with the Matrix Consulting Group to conduct an analysis of its Electric Vehicle (EV) Charging fee. The City last updated this fee in 2023 as part of the Citywide fee study. The City traditionally has a policy of achieving full cost recovery; therefore the analysis in 2023 resulted in a full cost calculated at $2.23 per kWh. The City adopted the fee at full cost but proposed a phased in approach to achieve full cost recovery. However, as part of due diligence, City staff wanted to re-analyze the cost assumptions of the analysis to ensure that all appropriate components were captured. Therefore, the City contracted with Matrix Consulting Group to review the existing rate structure but also provide comparative information and some alternative options. The following memo presents the updated calculation based on 2025 information, comparative information, and an overall analysis of options. EV FEE CALCULATION Redwood City has several Electrical Vehicle (EV) Charging stations throughout the City that it administers. Overall, there are 12 EV charging units managed by the Public Works Department. The project team worked with City staff to identify the total operating costs (maintenance, repair, electricity, and replacement) associated with the charging stations, as well as any departmental or citywide overhead. The following points provide an overview of each cost component: •Annual Maintenance Costs: These costs represent the annual contracted costs associated with general maintenance and upkeep of the charging stations. •ChargePoint Fees: This covers the flat fees charged by ChargePoint for access to the online dashboard for EV station management by City staff. This does NOT cover the fees that are pass- through charges by ChargePoint for transactions. •Annual Repair Costs: These costs represent the three-year average of costs incurred by the city in relation to repairing the specific charging stations. •Annual Electricity Cost: This represents the annual electricity cost incurred by the City in relation to the charging stations. It is based on the average kWh rate taken from one of the City’s charging locations and multiplied by total kWh distributed by all charging stations in the last full calendar year. •Annual Replacement Cost: This reflects the estimated cost to replace each charging station. The estimated cost is approximately $7,000 per unit, for 12 units, over the projected lifespan of 5 years. •Indirect Costs: These represent the indirect costs associated with managing the program such as Public Works staff support as well as Citywide overhead costs incurred. This is based on the federal de-minimis rate of 15%, which is intended as a standard coverage of overhead costs incurred. ATTACHMENT B7.B. - Page 6 of 8 133
