This is completely wrong. From those 12%, only a small fraction of
credits have to be generated from ZEV
vehicles, the rest can come from hybrids and various clean vehicles. See for example page 51 of
http://www.arb.ca.gov/msprog/zevprog/factsheets/zev_tutorial.pdf
It clearly says that for 100k cars sold, you need 790 credits from ZEV. Model S generates 3-5 credits per car (5 if the battery swap is "validated" as a fast refuel car) so about 200 MS could cover ZEV credit needs for 100k ICEs sold. And this is only in a dozen states. Sorry to interrupt the happy talk
(so it amounts to 0.2% - that if we forget there are Leafs and Volts around)
You need to re-read your own tutorial. The ZEV "requirement" for 2012-2014 is 12% of sales. Here is their example -
Note that the total obligation is 12,000 ZEV credits per 100,000 vehicles sold. Here are the key slides -
and
You are required to "fill up the glass" with credits. But you can only fulfill a maximum of 6% of the requirement with PZEV's (Prius Hybrid), 9% with AT ZEV (Volt/PiP Hybrid), 11.21% with Enhanced AT PZEV (Volt/PiP when they give it a 150k mile warranty) or NEV (Big golf carts), or all 12% with pure ZEV. The program is structured in this way to prevent Toyota (for instance) from being able to satisfy the entire ZEV requirement with just credits generated from the Prius. At the same time California wants ZEV's, so they allow each level of technology to satisfy more of the requirement.
So if Toyota sells 100k Prius's (and no other cars) they will get 20,000 Bronze level ZEV credits (
Edit: 0.2 credits/prius). Their ZEV requirement is 12,000, but the maximum number of bronze credits they could allot to their requirement would be 6,000, so they would still need to purchase 6,000 superior credits on the West Coast Exchange.
- They could purchase 6,000 gold credits
- or 3,000 silver and 3,000 gold
- or 3,000 silver and 2,210 silver+ and 790 gold.
Because gold credits can satisfy 100% of the requirement, they are the most valuable credit when selling on the exchanges. But if manufacturers fail to meet their 12,000 vehicle quota (with 100,000 sales), they are fined $5,000 per credit, period. So when it's all said and done manufacturers must meet the entire quota, and to the extent that they are deficient they need to pony up $5,000 per credit.

Has tesla released any data on zev credit customers? What about transaction info? Are they priced at a flat rated or based on demand? Could they make more by withholding sales towards the latter part of the year when customers are itchy to fill their quotas?
Tesla doesn't release anything. California will release credit balances, and net manufacturer transactions for 2012 in September.
The minimum price for a credit is $5,000, but the price tends to be more than that depending on supply and demand.
ZEV credits are traded on two exchanges, the West Coast Exchange for all states west of the Mississippi, and the East Coast Exchange for all Eastern states.
Tesla could withhold credits, but I don't see why they would. I don't buy the itchy hypothesis.
Also, a question you didn't ask, but folks need to understand, is that manufacturers have until September to fulfill the quota from the year before. So by September 2013, they need to have enough credits in their account to fulfill their 2012 quota or face regulatory action and fines. Also, if a manufacturer is short on credits, they must purchase any available credits on an exchange (doesn't matter which, since they can shift them back and forth).
In addition, folks seem to miss the fact that 15 states, representing ~50% of the total U.S. market, are subject to this quota. Carry rules let you satisfy some of the requirement in state B with sales in state A (at least until 2017), but you can't look at just California.
