Wisconsin regulators grant request for extension of time in case involving ATC 115-kV project

The Public Service Commission (PSC) of Wisconsin’s chairperson on July 13 granted a request for extension of time for the PSC to take final action on American Transmission Company’s (ATC) application involving a 115-kV project.

As noted in a July 7 memorandum to the chairperson from the administrator of the PSC’s Division of Energy Regulation, the purpose of the memorandum is to request an extension for the PSC to take final action on ATC’s Jan. 8 application requesting a certificate of authority (CA) for authority to:

  • Build the new 115-kV Ackley substation located between the Bunker Hill and Blackbrook substations
  • Rebuild Line M13 as double-circuit 115-kV between the Bunker Hill and Blackbrook substations
  • Retire and remove the Bunker Hill and Blackbrook substations
  • Uprate Line M13 from the Bunker Hill substation to the Kelly substation

The project’s total estimated cost is about $29.7m. The memorandum also noted that according to ATC, the project is needed to mitigate potential single-contingency overloads on Line M13, replace aging infrastructure on Line M13, and improve transmission system protection.

The PSC on May 5 served a notice of investigation, the memorandum said, adding that unless the PSC takes final action on a CA application for which no hearing is held no later than 90 days after the PSC issues a notice opening a docket on the application, the application is deemed approved by law and the CA is issued.

In this matter, the memorandum said, the 90-day deadline expires on Aug. 3. The PSC chairperson, for good cause, may extend the time for action for no more than an additional 90 days.

The memorandum further noted that PSC staff is working diligently on its review so that the PSC can take final action on the application as soon as practicable.

However, given the project’s scope and the fact that the project is a “Type II” action under Wisconsin Administrative Code and requires preparation of an environmental assessment, the administrator said that additional time beyond a 90-day schedule is necessary to complete staff’s statutory review processes of the proposed project.

If the request is granted, the new deadline for taking final action is Nov. 1, the memorandum said, noting that staff anticipates that only a short portion of the 90-day extension will be used before the PSC takes final action in the docket.
