Me too. In another article [not posted] on the subject, it was estimated that El Paso trading division made "over one hundred million" dollars on this so-called "scam".
My guess is that California made up the $3 billion figure just like they did the $9 billion that the "energy pirates" owed them: because it sounded good in press releases.
I'd second that guess. We also shouldn't forget that the California government was not buying natural gas as it was electricity. So, even if there were $50 billion in excesssive profits due to manipulation, it wouldn't be owed to "California."
