Since 1907, the Public Service Commission (PSC) has been responsible for the regulation of Wisconsin public utilities, including those that are municipally owned.
Who we regulate
Types of utilities regulated include electric, natural gas, water, combined water and sewer utilities and certain aspects of local telephone service. 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.
What we do
The PSC works to ensure that, in the absence of competition, adequate and reasonably priced service is provided to utility customers. PSC approval is required before utilities can change rates or build large power plant and major transmission lines. The PSC has specific rules it must follow prior to making decisions during the
Application Review Process.
How we are structured
The PSC is composed of three full-time Commissioners that have oversight of all PSC staff related activities.
PSC staff consists of auditors, accountants, engineers, rate analysts, attorneys, planners, research analysts, economists, consumer analysts, consumer specialists, court reporters and paraprofessional and administrative support personnel. These experts work in an advisory role to the Commissioners.
Our federal counterparts
The PSC has sole jurisdiction for utility regulation on the state level, but several agencies on the federal level perform parallel regulatory functions. These include the Federal Communications Commission, the Federal Energy Regulatory Commission, the Nuclear Regulatory Commission, and the Department of Energy.
All divisions represent the PSC on state and national committees requiring staff expertise on utility matters.
