Investing in utilities is usually a pretty boring affair, with the main attraction normally being a reliable quarterly dividend payment. Recent events at SCANA Corporation (NYSE: SCG), however, have been anything but boring. Dominion Energy could be the company's savior, but not if the government gets in the way.That's why investors would be better off investing in high-yielding Duke Energy Corporation (NYSE: DUK) or PPL Corporation (NYSE: PPL).
