CC 12-05-2023 Item No. 8. SVCE Grant_Supplemental Report
CITY COUNCIL STAFF REPORT
SUPPLEMENTAL 1
Meeting: December 5, 2023
Agenda Item # 8
Subject
Accept Silicon Valley Clean Energy Community Resilience Grant in the amount of up
to $233,963 to purchase two (2) Electric Vehicle Autonomous Renewable Charger (EV
ARC) portable solar‐powered charging systems.
Recommended Action
1. Adopt Resolution No. 23‐XXX accepting up to $233,963 in Community Resilience
Grant funding from Silicon Valley Clean Energy and approving budget
modification #2324‐316 increasing appropriation and estimated revenues by
$233,963 in 100‐87‐829 900‐990 for procurement of Electric Vehicle Autonomous
Renewable Charger units;
2. Authorize the City Manager to execute all documentation necessary to accept the
grant fundings; and
3. Authorize the purchase of two (2) Electric Vehicle Autonomous Renewable
Charger units, trailer and additional support and maintenance for a total cost of
$233,963 from Beam Global.
Staff’s responses to questions received from councilmembers are shown in
italics.
Q1: Attachment B states these units will be rotated every two months. Has
Staff been trained on moving these units? (Moore)
Staff response: Staff has yet to be trained on relocating the EV ARC unit but will
receive training when the unit and trailer are on site.
Q2: The report mentions these are designed for winds up to 160 mph, what
features do they have with regards to their seismic design? (Moore)
Staff response: See attached letter from independent structural engineering firm
confirming the system’s 160 MPH wind load certification and seismic design.
Q3: What is the cost differential from installing a permanent solar charger
station? An internet search of Solar Carport yields many options and styles.
(Moore)
Staff response: As the EV ARC procurement is fully grant funded, there are no direct
costs to the City for the purchase. Cost analysis to install a permanent solar charger
station was not evaluated. While a solar carport may provide different options and
styles, the disadvantage of the solar carport is that it is fixed. The EV ARC unit is
transportable and contains an electrical panel which can be relocated to any
emergency locations to provide power for the public and first responders.
Q4: What is the ongoing maintenance, expected useful life, and how is the
assembly, especially the battery be disposed of? (Moore)
Staff response: See attached O&M for the EV ARC unit. According to the
manufacturer, the unit has a minimum 20‐year lifespan from a structural perspective
while the individual components lifespans will vary based on the part. The unit is
delivered fully assembled. The lithium‐ion batteries in the system can be recycled via
Beam or via a third party.
Q5: What Level Charger will this have? (Moore)
Staff response: The EV ARC units will have a Level 2 charger.
Q6: It appears that the EV ARC 2020 is specified as the charging system but
the EV charger is selected by the City? Can that be competitively bid? For
instance, can we specify we want a Level 3 charger and choose the lowest bid?
(Moore)
Staff response: The Level 2 Enel X Way Juicebox charging unit is preinstalled with the
EV ARC unit. The solar array and battery are both insufficient to serve a Level 3
charger.
