Energy plan review
Everyone should review their energy plans at least once a year. The Texas Electricity ratings site makes it easy and informative. The plans are easy to read and choose from. It was a great experience.

Good Company so far
It has only been 2 months, but one thing they do that I really like is send a weekly email with your usage up to that point in the billing cycle and your expected electric bill. This allows me to reduce usage if needed and removes any "Bill Shock" when the monthly bill does post.

I appreciated the weekly usage updates that prepared me for the bill amount. The website could be a little more up to date with having a separate page for the account holders. I always had to search for the link to sign in. But it wasn't the worst thing in the world, and I would definitely continue with constellation if the price stays low.
