Public utilities: electrical and gas corporations: return on equity.

Existing law vests the Public Utilities Commission with regulatory authority over public utilities, including electrical corporations and gas corporations. Existing law authorizes the commission to fix the rates and charges for every public utility and requires that those rates and charges be just and reasonable. Existing law prohibits a public utility from changing a rate or altering a classification, contract, practice, or rule that would result in a new rate, except upon a showing before the commission and a finding by the commission that the new rate is justified and the public utility notifying its customers of the rate change.
