Frequently Asked Questions:

Electric VehicleDoes the Silicon Valley Power rebate EVs or chargers?
No. Rebates are not paid for EVs by Silicon Valley Power.

What do I need to know when purchasing my EV and installing a home charger?
Installing an Electric Vehicle (EV) charging system often requires changes to building wiring and utility electric services to meet the needs of this specialized equipment. You should:

  • Talk to your EV manufacturer for information about what you need to charge your vehicle and what regulatory requirements there might be.
  • Be sure to use a licensed Electrical contractor whose license is current for electrical work. The contractor should also follow the guidelines of the manufacturer and the requirements of City of Santa Clara building codes.
  • Get a permit from the City before installing your charging system. Learn about Building Inspection Info and Guidelines for Commercial and Residential EV charging systems.

Why is Silicon Valley Power concerned about your EV charger installation?

Though an individual EV charger may have a negligible impact on the utility electric system, the combined effect of several chargers in the same area could result in overloads on utility secondary wires and transformers. It is important that Silicon Valley Power is notified of any charging station installations to ensure that utility electrical system components are adequately sized to maintain high levels of service reliability.

Silicon Valley Power needs information on location (address), type of charging equipment, charging level (as defined by NEC, Article 625, see Table 1 below), and number of chargers or electric vehicles being installed.
