TXU Energy: bill went up
Variable-price plans can change price without notice after the first bill; fixed-rate plans change only for pass-through charges, and an expired fixed plan rolls to month-to-month.

Collect
- EFL
- contract expiration notices
- bills before and after the increase
Steps
Check the EFL to see whether the plan is fixed, indexed or variable.
If a fixed-rate price went up for a reason other than TDU, ERCOT or regulatory charges, dispute it as a billing error.
If a fixed plan expired and rolled to a month-to-month default product, choose a new plan; month-to-month plans can be left without a cancellation fee.
