How to sign up for service with Constellation
About five minutes online, free through Gatby. You need your service address and, for some plans, a recent bill or account number.
Check availability
Enter your ZIP to confirm Constellation serves your delivery area and to see your address-specific rate.
Choose a plan
Match the term and usage tier to your household. Read the EFL's 500 and 2,000 kWh columns, not just the headline.
Enroll online
Name, address, start date — about five minutes. A deposit may apply based on a quick credit check.
Switch on your next meter read
Pick your start date at signup. Typically 1–7 business days, with no outage and no technician visit.
Switching mid-contract
If you are inside a fixed term with your current provider, check that early termination fee first. When the annual saving beats the fee, switching early still wins — our rate check does that arithmetic against your actual bill.
Moving into a new home
Moving is the cleanest time to switch: no contract to break, no fee. Start the enrollment 5–10 days before your move-in date so service is live when you arrive.
How we get paid, and why it does not change this page
Constellation pays Gatby a commission when a customer enrolls through us. The rate you see is the rate Constellation charges customers who sign up direct — we do not mark it up. Gatby is a PUCT-licensed broker (BR230236), independent of every provider listed. Licensing
