| Category | Points | Evidence |
|---|---|---|
| Complaints to the state | 25 / 25 | 5 of 5, the best group, on the PUCT complaint scorecard, March 1 to August 31, 2026 |
| BBB rating | 5 / 5 | A+, accredited since 2011, checked October 5, 2026 |
| Fines and penalties | 12 / 20 | One PUCT penalty in 10 years: $160,000 in 2024 (Docket 55725, −8). The $66,825 bill-help contribution in the same case isn't a penalty. |
| Contract fairness | 9 / 20 | $150 cancel fee on its 12-month plan (5 of 5); no arbitration clause or class-action waiver (4 of 4); four extra fees: disconnection, reconnection, $6.95 phone payments and collection-agency fees (0 of 4); no simple 12-month plan (0 of 4); no free-cancel window beyond the 3-day legal minimum (0 of 3) |
| Price | 16 / 20 | No simple 12-month plan is listed, so we score its only 12-month fixed plan, 12 Month A/C Protect Plus for 2 Units: 15.8¢ in Dallas and 15.3¢ in Houston at 1,000 kWh. The 15.55¢ average is 98% of EIA's 15.88¢ Texas average for July 2026. |
| Time in business | 10 / 10 | Licensed February 26, 2001 (6); its terms describe a customer-funded energy assistance program (2); parent Constellation Energy publishes audited financials (2) |
Our method scores a company's simplest 12-month fixed plan. When there's no 12-month plan without bill credits, we score the simplest 12-month plan it has, say so, and it misses the 4 contract points for a simple plan. Full method: how we score.

Paying through Constellation's call center costs $6.95 each time, so paying online or by mail saves money. Its separate A/C service plan has its own line: 1-844-823-4663.
How many complaints does Constellation get?
Texans filed 26 complaints about Constellation with the Public Utility Commission of Texas (PUCT) from April through September 2026. For its size, Constellation gets the state's best rating: 5 of 5.
The PUCT's names: billing, discontinuance, provision of service, slamming (switching your provider without permission), cramming (unauthorized charges) and all other. Source: PUCT Customer Complaint Statistics, pulled October 5, 2026.
The state ranks every provider by complaints per 1,000 customers over six months, then sorts them into five equal groups. Constellation is in the best group, the one with the fewest complaints for its size.
39 complaints in three years, and the BBB shows no alerts. Reviews average 1.25 out of 5 across 16 reviews, but reviews don't count toward the grade.
What does Constellation charge in 2026?
Constellation offers 3 home plans in Dallas and 5 in Houston. At 1,000 kWh they cost 11.7¢ to 15.8¢ per kWh, delivery included. Its 11-month Simple Switch plan works out to about $139 a month in Houston, before taxes.
Average price per kWh from each plan's fact label as listed on Power to Choose on October 5, 2026, for ZIP 75201 (Dallas) and 77002 (Houston). Prices include delivery but not taxes. Green: the plan we score.
Which Constellation plan is cheapest for my usage?
Pick your city and the usage closest to your bill. The finder ranks every Constellation plan offered in your city and shows about what you'd pay each month.
When do Constellation's bill-credit plans cost more?
The 14-month bill-credit plan looks cheap at 1,000 kWh: 11.8¢ in Houston. But the $35 credit only comes in months you use 1,000 kWh or more. At 500 kWh the same plan costs 15.8¢, more than the 11-month Simple Switch plan.
Source: Constellation fact labels for ZIP 77002 on Power to Choose, October 5, 2026.
Rule of thumb: a bill-credit plan only pays off if you clear 1,000 kWh every month, even in mild spring and fal months. Fall to 999 kWh and you lose the whole $35. If your usage swings, the simple plan is the steadier choice.
What fees does Constellation charge, and how do I cancel?
Constellation charges $150 to cancel its 12-, 14- and 36-month plans early and $50 on Simple Switch plans. Its terms waive the fee if you move and show proof with a forwarding address.
- No arbitration clause or class-action waiver
- No cancel fee if you move and show proof
- No deposit at age 65+ if you're not behind, or with a letter of credit
- The default plan after your contract can be canceled anytime with no fee
- Only the legal 3 business days to cancel free after you enroll
- $6.95 every time you pay through the call center
- The last expiration notice can come just 15 days before your contract ends
- After that, the variable price is set at Constellation's sole discretion
