Cal. PUC § 1904

The commission shall also charge and collect the following fees:

(a) Except as otherwise provided in Section 1036 for filing each application for a certificate of public convenience and necessity, or for the mortgage, lease, transfer, or assignment thereof, five hundred dollars ($500). The commission may adjust this fee based on the Consumer Price Index.

(b) For a certificate authorizing an issue of bonds, notes, or other evidences of indebtedness, two dollars ($2) for each one thousand dollars ($1,000) of the face value of the authorized issue or fraction thereof up to one million dollars ($1,000,000), one dollar ($1) for each one thousand dollars ($1,000) over one million dollars ($1,000,000) and up to ten million dollars ($10,000,000), and fifty cents ($0.50) for each one thousand dollars ($1,000) over ten million dollars ($10,000,000), with a minimum fee in any case of fifty dollars ($50). No fee need be paid on such portion of any such issue as may be used to guarantee, take over, refund, discharge, or retire any stock, bond, note, or other evidence of indebtedness on which a fee has theretofore been paid to the commission. If the commission modified the amount of the issue requested in any case and the applicant thereupon elects not to avail itself of the commission’s authorization, no fee shall be paid, and if such fee is paid prior to the issuance of such certificate by the commission, such fee shall be returned.
