My True Cost: This website is owned and operated by CenterPoint Energy. When you input your smart meter number, the website can use your usage data to tell you how much your electric bill will be if you picked various plans on its website. CenterPoint charges the Retail Electric Providers if they want to be listed on this site, so there are far fewer plans here than on Power to Choose. When we compared for an inner loop address, there were 83 plans on My True Cost compared to 179 on Power to Choose. You may be missing less expensive plans if you don't look at the state's website also. More info
On the one hand, long-term, fixed-rate (contract) plans offer stability in pricing. If energy supply costs suddenly go up in your area, you won’t be left paying more than what you bargained for. You’ll have peace-of-mind. If you want to switch out of your contract before it ends with a lower cost plan, you’ll likely face a cancellation fee (early termination fee).
