If you're like most investors, you probably feel like you got left out of the natural gas rush. Stocks soared, early shareholders made bank, and now the natural gas sector is overpriced and inaccessible.

Except it's not. While pure play natural gas stocks have taken the spotlight, lesser-known utility dividend stocks like The AES Corporation (NYSE:AES), Duke Energy Corporation (NYSE:DUK), and Dominion Resources (NYSE:D) are still adding to their natural gas portfolios.

With decent valuations and steady dividends, these stocks could prove even more profitable in the long run. Check out the slideshow below for these companies' latest natural gas additions -- it's not too late to make your own natural gas dividend stock investment.
