TXU Energy recently released tips to help its Texas electricity customers learn more about switching energy providers.

The company's main advice was to take some time to evaluate a few simple questions.

"If you're moving to a new home in the state, you may have almost as many choices in electricity providers as you do soft drinks in the grocery aisle," the company said. "To help simplify this decision, TXU Energy now offers a new checklist to help you know what to look for when you're evaluating convenient service options and tech tools, value-added plan choices, and personal insight and control of your usage and bills."

After energy deregulation laws were implemented in Texas in 2002, regions of the state have developed extremely competitive energy markets, with more than 5.6 million households that can choose their electricity provider.

Questions to answer include how easy the company is to do business with, what plans are offered, if the provider makes the process simple to understand and how much control is handed to the customer.

Texas is one of several states with a bustling retail electricity market. Others include Ohio, Pennsylvania, Illinois and New York, all of which are experiencing a similar competitive environment.
