OK, here is that data I promised.....
The CVP is funded as part of the Air Quality Improvement Program, one of several schemes that are funded by CARB to the tune of $42.3m. Other programs receiving a share of this same money are the HVIP, LGER, AUTV, and Demo Projects ones.
The $42.3m CARB receives is a part of $192.3m annually allocated under AB118 in 2007. The legislation provides for these amounts through 2015, though it is up to CARB to allocate them to it's various programs.
The money in AB 118 is generated through an number of things - a small dollar amount from each vehicle registration, along with money generated from fines related to air quality and BAR infractions. So unlikely to dry up, so long as the legislation is in place.
However, if there are any mid-year shortfalls because the number of eligible vehicles being purchased outweighs the amount of funding available....a "first come, first served" wait-list will be generated for when future funding becomes available.
Conversely, any left over prior-year funds roll-over into the current year, as we will see this year with the ~$3m left over that will carry over to the $5m in 2011 funding, to make a total of ~$8m. Or enough currently for 1600 vehicles at the $5k level, most of which are likely to be LEAFs.
