New to Constellation and very Happy
I only signed up with Constellation about 2 months ago. So far so good. I was attracted by the price, terms of the agreement and other reviews.

Constellation was a suburb electric provider change.
Constellation filled our service request initiated through Texas Electricity Ratigs without any issues. Their billing is clear and concise with weekly updates to usage and approximate month to date billing.
