Eversource Energy (NYSE:ES) is a regulated electric and natural gas utility that serves the New England region. This is one of the most populated areas of the country, and so Eversource Energy is one of the biggest utilities in the United States. However, it is perhaps not as familiar to many households as some of the other major utilities. The utility sector in general has long been a favorite among conservative investors, such as retirees. There are several reasons for this, including the fact that these companies tend to have remarkably stable cash flows in any economic situation.
