Wisconsin Power and Light readies application on 650-MW gas project

Wisconsin Power and Light (WPL) currently plans to file an application with the Public Service Commission of Wisconsin (PSCW) in early 2015 for approval to construct an approximate 650-MW natural gas-fired combined-cycle plant in Beloit, Wisconsin, referred to as the Riverside expansion.

A decision from the PSCW on WPL’s request is currently expected by mid 2016, said WPL parent Alliant Energy (NYSE: LNT) in its Feb. 25 annual Form 10-K report. Construction of the Riverside expansion is also subject to the receipt of various approvals and permits necessary to construct and operate the plant. Subject to such approvals, construction is currently expected to begin in 2016 and be completed by early 2019.

Capital expenditures for this project are currently estimated to be approximately $725 million to $775 million to construct the plant and a pipeline to supply natural gas. The estimated capital expenditures exclude transmission network upgrades and allowance for funds used during construction (AFUDC). The Riverside expansion would replace energy and capacity being eliminated with the expected retirements of:

  • the coal-fired Edgewater Units 3 (69 MW, retire by the end of 2015), and Unit 4 (239 MW, retire by the end of 2018;
  • the coal-fired Nelson Dewey Units 1 and 2, 227 MW, retire by the end of 2015;
  • the gas-fired Rock River Units 3-6 combustion turbines, 169 MW, retire by end of 2019; and
  • the gas-fired Sheepskin Unit 1 combustion turbine, 42 MW, retire by end of 2019.
