Progress made on Edgewater 5 scrubber project in Wisconsin

An SO2 scrubber system on the coal-fired Edgewater Unit 5 went into construction in March and is due for completion in 2016, Wisconsin Power and Light told the Public Service Commission of Wisconsin in a July 29 project update.

In June 2013, the commission issued an order approving the application for a Certification of Authority to install a Dry Flue Gas Desulfurization System (DFGD) at Edgewater Unit 5. The estimated cost of the approved project was $413.7m, excluding allowance for funds used during construction (AFUDC). As of the July 29 update, the project is currently forecasted to be completed for about $300m, excluding AFUDC.

Construction activities commenced on March 3. WPL has a selected Engineer-Procurement-Construction (EPC) bidder. This contractor’s scope includes providing the DFGD technology, a circulating fluidized bed (CFB). WPL has signed a contract with the unnamed bidder.

During the second quarter of 2014, WPL issued limited notices to proceed to the selected bidder, releasing the bidder to draft various construction related permits; to execute the detail engineering and procurement activities necessary so that schedule can be kept; to execute construction activities required to maintain the schedule for the tie-in outage in 2016.

Mass excavation and export of soils are 100% complete and workers have started baghouse concrete foundation placement, the update said.

Edgewater consists of three coal-fired units; 3, 4 and 5. These units have nameplate generation capacities of 60 MW, 330 MW, and 380 MW, respectively.
