I just noticed that the New Jersey Clean Energy website has a page which includes a link to two lists of electric meters, along with an indication as to whether the meter has been approved for meeting ANSI CR.1-2008 standard of +/- 2% accuracy (as of December 1, only meters which meet this standard can be used to report readings for generation of SRECs).
Here are the two lists on that page. I'm inferring that the New Jersey Board of Public Utilities (NJ BPU) is saying that if it's approved on one of these lists, it's good enough for them. It might be worth a few minutes to look. Maybe your meter is good enough:

My meter (General Electric I-210+C, installed by PSE&G on July 25, 2012) is marked as "approved" on the New York list but as "not approved" on the California list. I just e-mailed my broker about it, because they seem to be the gatekeeper here, but I don't have much hope. I already annoyed the hell out of them a couple of weeks ago and was finally told that my meter doesn't meet the standard. I just figured that now that I'd seen a list, I'd ask again and point the list out.
