I can only speak from Generation experience. I worked for the roving maintenance group first. If you like travel and don't care about being away from family, you'll make money. I transferred into a permanent plant position. Front line supervision is pretty good on the whole, above that, it's the typical production grab mentality. You'll have to put up with the whole LEAN initiative (which hasn't worked), and the Sarban-Zoxley (sp) study that caused all the parts and tooling you need to disappear (God forbid a company has to pay tax on supply stock). The benefits have been decreasing steadily. If you want a place to gain experience in generation before they phase you out for the T&D profits, then AEP is for you.
Plants are a good place to work. Camaraderie. Union represented hourly workforce for the most part.
Steadily decreasing benefits, transition out of generation, inane policies about efficiency and saving money
