Wis. Admin. Code PSC § 113.0923
Upon written application to the commission by any electric utility customer, the commission will referee a test covering the accuracy and integrity of the customer's power meter installation, including an inspection and verification of the connections and any other check or test which appears desirable. The test will be performed in accordance with ss. PSC 113.0905 through as 113.0915 applicable and shall be made in accordance with s. PSC 113.0811(1) (c). The commission may limit the availability, number or frequency of such referee tests for the same customer at the same location where, in its judgment, the requests are too frequent, burdensome, abusive, or otherwise unwarranted by the available information or evidence.
