Wisconsin Public Service Commission
The creation of the Public Service Commission is designated in Wisconsin Statutes.
There is created a public service commission. No member of the commission may have a financial interest in a railroad, water carrier, or public utility. If any member voluntarily becomes so interested, the member's office shall become vacant. If the member involuntarily becomes so interested, the member's office shall become vacant unless the member divests himself or herself of the interest within a reasonable time. Each commissioner shall hold office until a successor is appointed and qualified. A commissioner of the public service commission may not do any of the following: (a) Be a candidate for public office in any election. (b) Directly or indirectly solicit or receive any contribution, as defined in s. 11.01 (6), for any political purpose, as defined in s. 11.01 (16), from any person within or outside of the state. (c) Act as an officer or manager for any candidate, political party, or committee organized to promote the candidacy of any person for any public office. (d) Serve on or under any committee of a political party.
The Public Service Commission is responsible for the regulation of Wisconsin public utilities, including those that are municipally-owned. Typical types of utilities regulated include electric, natural gas, telephone, water, and combined water and sewer. More than 1,100 utilities are under the agency's jurisdiction. Most of these must obtain PSC approval before: setting new Rates, issuing stocks or bonds, undertaking major construction projects such as power plants, water wells, and transmission lines.
The Public Service Commissioners' Office is comprised of the three Commissioners, Executive Assistant to the Chairperson, Executive Assistants to respective commissioners, the Secretary to the Commission, the Legislative Liaison, the Administrative Law Judge, Director of Governmental and Public Affairs and Public Information Officer as well as the Commissioners' support staff.
