You need to be able to cast a country mile. Heavy lures, or rods that make it easy to do that. Kastmaster spoons are a good choice.
As far as the "hot bite" goes, that is dependant on the weather. You really want an "extended" cold snap. Not just a couple of days, but a week or more. Weekdays are best; less competition, and both generators are usually going. Weekends see more folks fishing, and one or both generators could be off.
You might, or might not, be able to spot whether or not the stacks have exhaust coming out of them. There's a lot of scrubbers in there to clean the air up. Don't expect to "see smoke". Instead, look "through" the air above the stack and see if there's any heat distortion in the air.
