With continued development, Duke Energy is one of the few companies capable of outperforming expectation on a recurrent basis. Serving the Kentucky, Indiana, and Carolina electric and natural gas market, Duke at one time was considered to be serving a niche market in a smaller-than-profitable geography. The company has since shrugged off that perception, pursuing a growth and development strategy that has forced consumers into switching to Duke’s now-renowned customer service and reliable product. Over the last few years, the company has served to develop a nuclear energy site, and is making great strides in attempts to move into sustainable energy markets.
