In regulated states, there is no question. You’ll always get electricity or natural gas from a utility. You’ll be assigned a utility according to where you live, and there is a real option to break away.

In most states that have deregulation, the utility delivers electricity and/or natural gas to your home or business. But you may exercise the power to choose whether you buy those products from a utility or from a supplier.

The key is to find the utility’s price to compare – the cost of basic electricity or natural gas supply. It should be listed on your monthly bill separately from the cost to deliver energy to your home. Once you know the price to compare, it’s easy to use Choose Energy’s marketplace to see if you can beat that price.

In Texas, you must purchase an electricity plan from a retail electric provider. Again, Choose Energy’s marketplace can help with that, allowing you to see the plans in your area. Sort by rate, term, renewable content, and more to make your choice.
