Our Commissioners

​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​The Public Service Commission of Wisconsin (PSC) is composed of three full-time Commissioners who decide the cases brought to the PSC for changes in utility operations, rates and for construction projects after a complete and thorough review of all the records compiled in the case, including public comments. Commissioners are appointed by the Governor and confirmed by the State Senate for staggered, six-year terms.

One of these Commissioners is appointed Chairperson by the Governor for a two-year term. The Commissioners’ Office, under the direction of the Chairperson, has oversight of all PSC staff-related activities.

Staff of the Commissioners' Office may be reached by contacting the Executive Staff Assistants at PSCCOSupport@wisconsin.gov​​.​​​​

Warning: rules regarding ex parte communications​

Any communications with individual Commissioners on contested cases before the commission may constitute a prohibited ex parte communication [Wis. Stat. § 227.50]. If you wish to comment on the record on a pending matter, please do not contact individual commissioners. The PSC has established an official method for receiving public comments that can be accessed at the PSC Comments page on our web site. Only comments submitted in this manner will be officially recorded and reviewed by Commissioners before deciding pending cases.
