Vantaggi
Xcel Energy offers competitive salaries and great benefits, and probably a little more job security than a lot of other companies. At the management level, they have a good annual incentive plan that paid out at least 100% every year of my tenure except one. They provide decent opportunities to train and learn within the company.
Svantaggi
Xcel does not do a good job of providing cross-training opportunities to create future leaders of the company. As a result, employees tend to get pigeonholed into certain departments or specialties, which makes it hard to move into higher level positions within the company - assuming you would want to. Executive team decision making is slow and ponderous, with many missed opportunities due to an inability to get sign off in time.
