. Charging Station Maintenance and Program AdministrationsCosts — Coulomb is warranting its equipment for one year from the date of installation for the EV stations and two years for the ChargePoint equipment. As a result, there will not be any City maintenance charges through January 2013. When Coulomb's warranty expires, the City will need to assume the cost of maintaining, operating, and periodically upgrading the equipment as well as an annual network service subscription fee. At this time, staff does not have the data to accurately determine these costs however, based on an assessment of the existing equipment, maintenance will be required to assure proper operation and to address any vandalism. Further, staff anticipates continued costs related to promoting the program and processing costs related to PG&E bill payments, budgeting and other related items. Considering these costs, staff has fixed it administration fee at $0.40 which is consistent with the anticipated ChargePoint transaction fee. DISCUSSION Based on the pricing variables included in the three cost areas noted above, it is not practical to develop a pricing structure where the fee is exactly equal to the cost of service. Further, even if a direct fee for service structure could be developed, it may be confusing for consumers. As a result, staff is recommending a $1/hour flat fee amount that would cover all costs related to the program. Development of the $1/hour fee is based on the following analysis: Components for EV Charging Stations Cost Centers Lowest Amount Highest Amount Comments ChargePoint Transaction Fee $0.20 $0.40 Represent the lowest and highest fee that will be char.ed PG&E Charges $0.13 $0.44 Assumes winter off-peak and summer peak ChargePoint Processing Fee $.01 $0.02 Assumes 3% and 6 % of PGE charges City Maintenance/Admin Fee $0.40 $.0.40 Covers maintenance and admin Total $0.74 $1.26 Average Estimated Cost $1.00 Recommended Hourly Usage $1.00 Fee Staff has reviewed fees in other communities throughout the state and has seen that per hour charging station fees vary from a low of$0.50 to high of$2.25 (maximum) per hour. As indicated the attached resolution amending the City's Master Fee Schedule, the City Manager is authorized to adjust the fee based on program experience and cost adjustments to PG&E rates. However, increases will not occur more than twice annually. S tte 1, • Approv by: VWu Daniel S ith Nelson Fi ho Director perations Services City Manager Attachments: 1. Resolution Page 3 of 3
