Alliant Energy‘s (NYSE: LNT) Wisconsin Power and Light subsidiary has signed GSL, a joint venture between Graycor Industrial Constructors and Sargent & Lundy LLC, as the engineering-procurement-construction (EPC) contractor for a selective catalytic reduction (SCR) project for NOx control on the coal-fired Unit 2 at the Columbia power plant.
Wisconsin Power and Light (WPL) and other co-owners won a Jan. 30 approval for this project from the Public Service Commission of Wisconsin. The estimated cost of the approved project was $150,000,000, excluding AFUDC.
Said an Oct. 28 project update filing with the commission: “In November of 2014, WPL issued a Request For Proposals (‘RFP’) for Engineer-Procurement-Construction (‘EPC’) services to perform the installation of the SCR. WPL received six (6) responses to the RFP in late February, 2015. On September 1, 2015, WPL signed a contract with GSL for the EPC services. GSL is a joint venture between Graycor Industrial Constructors and Sargent & Lundy, LLC.”
The company noted that the anticipated in-service date for the SCR is April 30, 2018. WPL is currently working with GSL to prepare an application or exemption request for an Air Construction Permit with the Wisconsin Department of Natural Resources. Engineering activities were executed during the period of this report (the third quarter of this year) to support the project schedule.
Under the commission approval, construction must commence no later than Jan. 30, 2016. Based on the initial schedules submitted by GSL, WPL said it expects construction to commence by approximately April 2016. WPL expects to request an extension on the construction start deadline.
WP&L, Wisconsin Public Service Corp. (WPSC) and Madison Gas and Electric Co. (MGE) co-own the plant. The Columbia Energy Center is located south of Portage, Wisconsin, along the Wisconsin River. The facility consists of two coal-fired units (Units 1 and 2). These units began operation in 1975 and 1978, and have nameplate capacities of 512 MW and 511 MW, respectively. The utilities jointly own both units, with WP&L holding a 46.2% share, WPSC holding a 31.8% share, and MGE owning the other 22%. WP&L operates both units. Both units currently utilize sub-bituminous Powder River Basin coal obtained from various mines.
