With a fixed rate energy plan, the price you pay for electricity each billing period will not change for the duration of your contract.
However, the price that your TDSP charges to deliver to your home may change. This can only happen if the Public Utility Commission approves the change. If that happens the TDSP charges on your bill would increase, but all the other charges (energy charge, base charge or usage charge) have to remain the same – those are fixed.
You can see all these elements of your price broken down at the top of your EFL.
Variable rate energy plans offer flexibility to customers that aren’t ready for a set contract. Customers on a variable rate plan can cancel their electricity plan anytime without penalty. However, the rate you pay for electricity may vary from month to month.
