As do I and nobody has the balls to admit it...
8 days since the event and we still haven't a concrete cause.
BS... They know how it happened, why it happened and how it could happen again, but they aren't telling because...it could happen again.
The cause is simple, some half trained union worker was putting additional unit on line. He allowed the system to moterize the unit he was bring on line. This is just about the only way you could get the sharp spike in power, anything else would cause a burn out.
Such impatience. This reminds me of the "30 days since the end of the war and Iraq is still dangerous" crowd.
There is a mountain of evidence to pull together from thousands of data sites across two countries, eight states, quite a few utilities, about 100 power generating units, many many substations, several transmission companies, and too many power monitoring stations at universities, hospitals, schools, and businesses to count. We are talking about a situation where a millisecond can mean the difference between getting the events right or wrong, and most of the data time stamps are not synchonized that well. It is possible that subpoenas will need to be resorted to in some cases. This will all take time. Jumping to conclusions could be very embarrassing for the investigators and costly for some innocent people and/or companies. The investigators will be quiet and thorough. It's very frustrating I know, but it has to be that way to get it right.
Have you ever done a root cause analysis on a complicated system? Sometimes, the piece of data you need does not exist. So you have to infer it from several other pieces of data. Maybe some of those data bits are not available and have to be found through experimentation and analysis. The report will come. If the worm did it, I'm sure that that will come out too.
