MISO files construction deal for Wisconsin Power and Light project

The Midcontinent Independent System Operator, on behalf of American Transmission Co. LLC, on July 22 filed with the Federal Energy Regulatory Commission an “Agreement for Engineering Design and Procurement of Material for a Portion of the Required Network Upgrades – MISO Project J390,” with Wisconsin Power and Light (WPL).

WPL currently plans to own and construct a generating facility located in Rock County, Wisconsin, which will consist of a proposed two-on-one (two combustion turbines and a heat recovery steam generating unit) combined cycle, natural gas-fired plant and associated facilities with a total output of 702 MW (net). WPL’s generating facility is expected to interconnect to the transmission system owned by ATC and operated by MISO.

This is the Riverside Energy Center expansion project, located at the existing Riverside power plant.

ATCLLC, WPL, and MISO are currently jointly coordinating to comply with the various provisions of MISO Tariff Attachment X regarding generator interconnection, and relevant studies are currently underway. WPL’s Attachment X Generator Interconnection Agreement (GIA) has not yet been completed, but ATCLLC, WPL, and MISO expect to execute a GIA in the near future. In the interim, WPL is interested in interconnecting its generating facility as soon as possible. WPL has requested that ATCLLC complete certain work prior to completion of the studies required by the GIA and the execution of a three-party GIA between ATCLLC, WPL, and MISO. The attached agreement sets forth the terms and conditions pursuant to which ATCLLC will assist WPL in this regard.

The generating facility is presently expected to interconnect on the 345 kV W-10 line in between the Paddock Substation and the Rockdale Substation.
