We've been digging through corporate records, power use records and whatnot. At first glance it appears that the California blackouts were caused by widespread overuse, but this isn't actually the case, although I don't think you could tell without the advantage of a confederate in the future.
Instead, most of the unplanned power consumption was the result of only a few heavy users scattered around the pacific coast. That wouldn't be so suspicious, the electronics firms on the west coast probably use a lot of power, but it looks like they are all owned by two larger holding companies. These companies, though, don't seem to have any assets aside from these power-using subsidiaries. No employees or physical plant that we can discover. They're privately owned, so we can't get a lot of information yet, except that they both seem to be owned by the same parent company, which also seems to be devoid of an actual money-making business. What we need to determine now is who owns the final company, and what, if anything, was happening to all that power. We can't tell you that for certain yet, but I can tell you one thing: the final holding company appears to have relations with IBM and Stanford University. Does this smell like a winner to anyone else?
