Overview
Tariffs are formal filings that utilities make with the Commission, tariffs cover everything from the rates a customer pays for water service each month to what qualifications a customer must meet in order to take service under a given rate offering. Tariffs have the force and effect of contracts. As contracts, tariffs can be viewed as setting out the legal obligations of both parties – the customer’s and the utility’s. Tariffs are subject to review by the PSC, and in some instances, the courts.
A utility must file its tariff with the PSC. Tariffs on file with the PSC are available to the public for inspection on the PSC web site. Once in effect, a utility must charge a customer the tariffed rate. Per Wis. Stat. § 196.60, a utility cannot discriminate in the rates it charges customers. Tariff revision requires a hearing if the new tariff would diminish the level of service received by a customer under an existing tariff or have the effect of increasing charges to a customer for an existing service. A hearing is not required if the effect of the tariff would be to reduce rates, or if the utility is offering a new, optional tariffed service. However, the revised tariff would still be subject to PSC staff review.
