CBS has Enron Trader tapes.

CBS News:
The tapes, from Enron's West Coast trading desk, also confirm what CBS reported years ago: that in secret deals with power producers, traders deliberately drove up prices by ordering power plants shut down.

"If you took down the steamer, how long would it take to get it back up?" an Enron worker is heard saying.

"Oh, it's not something you want to just be turning on and off every hour. Let's put it that way," another says.

"Well, why don't you just go ahead and shut her down."

Officials with the Snohomish Public Utility District near Seattle received the tapes from the Justice Department.

A spokesman for the utility said "This is the evidence we've all been waiting for. This proves they manipulated the market."

That utility, like many others, is trying to get its money back from Enron.

Pretty damning stuff.
One of the workers talked about how great it would be to have Ken Lay as the Secretary of Energy. Hah!
