Wisconsin Public Service Commission Certificate Overview (8-WI-c)
The WPSC has two separate review processes for transmission projects in Wisconsin. The process required depends on the voltage, length, and cost of the project.
Public Service Commission Certificate Overview Process
8-WI-c.1 to 8-WI-c.2 – Is the Transmission Project 100 kV or more and Greater than One Mile in Length?
A developer may need a Certificate of Public Convenience and Necessity (“CPCN”) from the Wisconsin Public Service Commission (“WPSC”) for transmission line projects designed for operation greater than 100 kV or more that exceed one mile in length. 196 Wis. Stat. §§ 196.491 et seq. For information, see:
8-WI-c.3 to 8-WI-c.4 – Does the Transmission Project Require a Certificate of Authority?
A public utility must obtain a Certificate of Authority (“CA”) from the Wisconsin Public Service Commission (“WPSC”) in the following circumstances:
- “…prior to constructing any public utility plant, extension or facility, or rendering service…directly or indirectly serving any other public utility or agency…in any municipality…” 196 Wis. Stat. § 196.49(1); 112 Wis. Admin. Code § 112.03;
- prior to “…the construction, installation or operation of any new plant, equipment, property or facility, or the construction or installation of any extension, improvement or addition to its existing plant, equipment, property…or facilities...” whose estimated gross cost exceeds a particular amount, as signified below regarding exemptions. 196 Wis. Stat. § 196.49(2); 112 Wis. Admin. Code § 112.05(1). A project for constructing or rebuilding a transmission line, including necessary terminations and related new substation or substation additions, or a new substation or switching, or a distribution system extension are included in the threshold above that may require a CA. 112 Wis. Admin. Code § 112.05(1)(c)-(f); and
- prior to “…construction, installation or…operation an initial interconnection with the transmission system or another electric utility, with no existing transmission interconnections…” 112 Wis. Admin. Code § 112.04.
Transmission system is defined as, “…electric lines and associated facilities, designed and operated at 40 kV or higher voltage, that transmit power from generating plants to and between distribution systems.” 112 Wis. Admin. Code § 112.02(9).
