Some of the Enron Accountants were crocks.
Some of the bankers and investment companies Enron dealt with were crooks.
Some of the politicians that Enron tried to buy were crooks.
Some of the Enron employees were crooks.
As to "these guys" (being associated with the questions on plant shut downs), I would like to know a little more about what there positions within the company were, before, I would call them crooks. The reason is that there were several well publicized cases where various California officials said that energy marketing firms had illegally held their plants off the market.
In the several previous investigations (if my memory is correct) of this by State officials and federal officials what was generally found was needed maintenance, air pollution control limits, gross failure to pay the power plant operator to the point that the operator could no longer affort to maintain the plants and had to shut them down (lots of small renewables including windfarms) and bad information provided by the California state agency responsible for generation scheduling were why the plants had been shut down and not available to deliver power.
