My tracking shows approximately 460 LEAF rebates applied for or refunded in CA since LEAF deliveries began (also includes Tesla Roadsters, but unlikely other full $5k rebate cars since Honda Clarity Hydrogen cars have not been newly delivered for a couple of years now). Funds, excluding the $2 million that are yet to be added to the 2011 allotment, remain for about 935 rebates, or about double the number of cars already delivered in CA. Add in the $2 million and that number becomes 1335 additional rebates available and funded. I don't know, but others might, whether all of those will be fully funded at $5k. Of course, as other full fledged EVs come on the market, most of them will also be eligible for rebates, but the earliest we'll see any of them is late this year. Also note that neighborhood EVs and electric motorcycles are funded out of the same fund, but at lower rebate amounts and likely in much lower numbers.
Also, just a note of interest and perspective, we just reached the level of refunds equaling the 2010 funding total, so you could say we just used up the 2010 fund. It's pretty encouraging to me to know that we are just starting into the 2011 funds here at the end of April. Of course, a lot of that is because of the delays in shipping LEAFs.
Another note for those who come more recently to the discussion, and the CCSE folks monitoring this thread might want to comment. The CVRP program is intended to run through 2015, I believe. It's common on this forum for people to say "I'm only buying (or leasing) my LEAF if I get the CA rebate". Do realize that the program is intended to continue through 2015 and there will be wait listing for later funding in order of delivery of the cars if funds run out. Funding is approved each year from CARB funds and requires the state budget to be approved before funds flow to the CVRP, but don't be mislead into thinking that once the current funds are gone, that you're definitely not getting a rebate. Of course, being on a wait list is not the same as being assured of getting a rebate, and you may well need to know that you have a reserved rebate before committing to buy or lease a LEAF. California state budgets being what they are, you can be your own judge as to whether funding will be diverted to other needs. But my understanding is that CARB funds are identified for established CARB goals and it is not a simple matter to divert those funds to other uses.
Happy electric motoring!
