Wisconsin Statutes Utilities (Ch. 196 to 201) § 196.07. Balance sheet filed annually

(1) Each public utility shall close its accounts annually on December 31 and promptly prepare a balance sheet of that date. On or before the following May 1 every public utility shall file with the commission the balance sheet; counts of the numbers of meters serving residential, small commercial, and small industrial customers as of December 31; and any other information the commission prescribes, verified by an officer of the public utility. The commission, for good cause shown, may extend the time for filing the balance sheet and prescribed information.

(2) If a public utility fails to file a report with the commission containing its balance sheet and other information prescribed by the commission by the date the report is due under sub. (1), the commission may prepare the report from the records of the public utility. All expenses of the commission in preparing the report, plus a penalty equal to 50 percent of the amount of the expenses, shall be assessed against and collected from the public utility under s. 196.85. The amount of the charge to a public utility shall not be limited by s. 196.85(1)(b) and shall be in addition to any other charges assessable under s. 196.85. The penalty provision of the charge shall be credited to the general fund under s. 20.906.
