Public Service Commission opens summary investigations into multiple utility dockets, approves procedural notices

The Public Service Commission voted Thursday to open summary investigations into multiple utility dockets and approved several procedural notices and minutes during its May 28, 2026 open meeting.

Chair called the meeting to order and asked the commission secretary to review the agenda. The Commission Secretary told commissioners that “each commissioner has independently reviewed the minutes of the open meeting of Thursday, May 21st, 2026,” and that no further discussion of those minutes was necessary. A commissioner moved to approve the May 21 minutes; another seconded and the motion carried.

The commission then turned to agenda notices and a set of utility dockets connected with agenda items 7 through 12. The commission secretary enumerated the dockets listed for summary investigation: 1830 WI102; 1870WI00; 2810WI00; 3545WI103; 5935 WI; and 6470WI00. The secretary described the procedure the commission would follow for those dockets: opening a summary investigation under subsection 196.28 (as cited in the meeting), directing staff to order additional information from the utilities, and requiring the utility to file a conventional rate-case application within 30 days of service of the related order. The secretary said that if a utility fails to provide the additional information by filing a conventional rate case application, staff will prepare the necessary filings and open a separate docket to establish reasonable rates, which may include contracting with an outside consulting firm.

Following that explanation, commissioners approved a set of procedural actions by voice vote. They approved notices of investigation associated with agenda items 2 and 3 and approved notices of proceeding associated with agenda items 4 through 6. Commissioners then voted to open summary investigations consistent with the commission secretary’s description for the dockets tied to agenda items 7–12. The votes were recorded in the transcript as “All in favor?” with responses recorded as “I.” The transcript does not state the number of commissioners voting or provide a roll-call tally.

The Chair concluded official business and announced that the next open meeting is scheduled for Thursday, June 18, 2026, at 10:30 a.m. A motion to adjourn carried and the meeting was adjourned.

What happened next: No further action was recorded during the open meeting. The commission directed staff to proceed with the investigations and any follow-up filings as described.
