Constellation 12 Month Usage Bill Credit
Two credits stack, but each has its own threshold. This offer pays $35 at 1,000 kWh and another $15 at 2,000 kWh. At 2,000 kWh the total credit is $50, not $15. Below 1,000 kWh neither applies. Both thresholds matter when comparing the advertised examples.

What goes into the bill
Oncor delivery was checked on September 23, 2026 against the delivery schedule updated September 13, 2026. The same delivery amounts appear in the archived EFLs; 4Change’s EFL refers to this schedule. These assumptions stay fixed in this dated analysis.
See what changes at the credit threshold
Each bar is one separate monthly bill. Compare the readings just below and at each threshold: using slightly more electricity can qualify for a credit that changes the bill sharply.

|---|---|---|
| 500 | $79.51 | $0.00 |
| 999 | $154.80 | $0.00 |

1,000 kWh on average is not 1,000 every month
Our standard seasonal example uses 12,000 kWh over twelve months. Its modeled annual cost is $1,684.46, equivalent to 14.04¢/kWh. It earns a credit in 5 months, with $175.00 in total credits.
| Month | kWh | Credit | Cost |
|---|---|---|---|
| January | 1,010 | $35.00 | $121.46 |
| February | 890 | $0.00 | $138.36 |
| March | 790 | $0.00 | $123.27 |
| April | 720 | $0.00 | $112.70 |
| May | 890 | $0.00 | $138.36 |
| June | 1,180 | $35.00 | $147.12 |
| July | 1,390 | $35.00 | $178.80 |
| August | 1,430 | $35.00 | $184.84 |
| September | 1,220 | $35.00 | $153.15 |

Who should take a closer look
Review how often you reach each threshold. Our standard seasonal year reaches 1,000 kWh in five months and never reaches 2,000, so it receives the first credit five times and none of the second.
The higher credit at 2,000 kWh does not guarantee a lower average rate than at 1,000: the credit is spread across more electricity. The provider-authored EFL for this offer is hosted by ElectricityPlans.com.
Read the contract’s cancellation conditions and exceptions. A fixed energy rate does not freeze delivery charges or other changes permitted by the contract.
