Rate-case process

How utility rates are set in Louisiana

Formula-rate plans alongside utility-initiated base-rate reviews

Major electric utilities use Commission-approved formula-rate plans with annual evaluation periods, while the Commission can conduct full rate reviews. Fuel and other riders change between full reviews.
