Not OP, but California Air Resource Board gives a significant rebate and I know if you live in the Central Valley you can get another rebate. That's 10k+ from the state alone up to 120k income for a family of 4. Our local utility also paid for a home charger($500) and $500 towards installing the charger. Our utility also put a second meter on our power for the charger that costs a reduced rate to charge with.
