With more and more states opening their energy markets to competition, retail electricity providers are slowly becoming national businesses. Ambit Energy has continued this trend with plans to begin 2012 with a move into Connecticut and Massachusetts.

Ambit began in the heartland for electricity deregulation in Dallas, Texas, but quickly expanded to other states as they began to open up. The electricity provider already serves customers in Illinois, New York, Pennsylvania and Maryland as well as its home state.

Now, however, the company will open up its services to residents and businesses in the two main New England states with competitive electricity rates.

"Our goal is to be the finest and most respected retail energy provider in America," Jere Thompson, Jr., Ambit co-founder and chief executive officer, said in a statement. "With thousands of excited, hard-working Consultants helping us, 2012 promises to be the biggest in our history."

The Massachusetts Executive Office of Energy and Environmental Affairs reports that around 15 percent of all the state's customers receive their electricity from alternative electricity providers. In Connecticut, the Department of Energy and Environmental Protection reports that more than 41 percent of all customers use such electricity suppliers.
