Texas electricity definition

Fixed-rate plan

A term retail product whose price remains fixed under the rule's definition, subject to allowed changes such as TDU charges or regulatory fees.

What it means

Fixed does not necessarily mean the total bill never changes. Usage, delivery charges, taxes, recurring fees, and conditional credits can still change the amount due.

Eyebiss interpretation
