PSC 112.07. Any subsequent interconnection by mutual agreement with the same electric utility does not require commission approval except as provided in s. PSC 112.05. The electric utility shall, however, report each subsequent interconnection to the commission at least 90 days before it begins construction. The report shall include a description of the project, its location, the estimated gross cost, and a discussion of the need. Electric utilities may, without commission authorization, establish temporary or emergency interconnections between their systems by mutual agreement, but shall promptly report such interconnections to the commission within 10 days of the date established and the date discontinued. PSC 112.04 HistoryHistory: Cr. Register, November, 1995, No. 479, eff. 12-1-95. PSC 112.05PSC 112.05 Construction of electric utility facilities.

This paragraph applies to projects or combinations of projects where the same replacement, modification or addition is known to be required at more than one unit at the same plant over a reasonably short period of time and the total cost of the combined work exceeds the applicable amount specified in sub. (3). This paragraph also applies to the initial construction of major new waste disposal facilities for the plant, even if not located at or adjacent to the existing plant site. This paragraph does not apply to replacements, modifications or repairs to a hydroelectric dam or related civil works to comply with dam safety or similar regulatory requirements, if the capacity or operation of the generating facilities is not significantly changed. PSC 112.05(1)(c)(c) A project for constructing or rebuilding a transmission line, including necessary terminations and related new substation or substation additions. This paragraph does not apply to the relocation or modification of a segment of an existing transmission line, if the utility is ordered to relocate or modify the line to accommodate highway or airport construction, nor to the reconstruction or restoration of a segment of an existing transmission line made necessary by storm damage.

Approve the project by acknowledging, in writing, receipt of the report and accepting it for filing. PSC 112.05(1m)(c)2.2. Direct, in writing, that the project shall not proceed until specific approval is granted under s. 196.49, Stats. PSC 112.05(1m)(c)3.3. Approve the project by taking no action within 90 days of receiving the utility’s written report. PSC 112.05(1m)(d)(d) This subsection does not apply to a project that requires a certificate of public convenience and necessity under s. 196.491 (3), Stats. PSC 112.05(2)(2) A Wisconsin electric utility proposing to construct, install or place in operation any of the utility facilities listed in sub.

Notwithstanding sub. (3), if a significant portion of the cost of the project will be allocated to Wisconsin for ratemaking purposes, the commission may require that the utility submit an application under s. PSC 112.06, for commission authorization prior to construction, installation or operation. PSC 112.05(3)(a)(a) Cost thresholds for projects requiring commission review and approval under this section are those specified in s. 196.49 (5g) (ar), Stats., as revised under par. (b). PSC 112.05(3)(b)(b) Beginning on May 1, 2014, and on May 1 of each successive even-numbered year thereafter, the commission shall adjust the cost thresholds in s. 196.49 (5g) (ar), Stats., to reflect changes to the cost of electric utility construction based on the cost index numbers published in the “Handy-Whitman Index of Public Utility Construction Costs, Cost Trends of Electric Utility Construction — North Central Region for Total Transmission Plant”. PSC 112.05(3)(c)(c) The commission shall notify all electric utilities of the resulting adjusted cost limits by May 15 of each even-numbered year and shall publicize the adjusted cost limits on the commission’s website. If the Handy-Whitman Index is no longer available, an equivalent successor index may be used which is generally recognized by the electric industry and acceptable to the commission. PSC 112.05 NoteNote: The commission maintains or has access to the Handy-Whitman Index of Public Utility Construction Costs and this reference or a copy may be reviewed by contacting the commission’s offices.
