Wisconsin Power and Light told the Public Service Commission of Wisconsin in a Jan. 22 quarterly update that as of the end of December, a Dry Flue Gas Desulfurization system on the coal-fired Edgewater Unit 5 was about 88% complete.
In June 2013, the commission had issued an order approving the application for a Certification of Authority to install a Dry Flue Gas Desulfurization System (DFGD) at the Edgewater Generating Station on Unit 5. The estimated cost of the approved project was $413,710,000, excluding AFUDC. As of this Jan. 22 update, the project is currently forecasted to be completed for approximately $264,900,000, excluding AFUDC.
Construction activities commenced in March 2014. WPL selected and issued a full notice to proceed to the Engineer-Procurement-Construction (EPC) bidder. This contractor’s scope includes providing the DFGD technology which will be a circulating fluidized bed (CFB) scrubber.
At the end of December 2015, the project was on schedule and 88% complete, with engineering for the project 100% complete. At the end of December 2015, procurement by the EPC contractor for the project was 99% complete. Commissioning of the DFGD is due to start in June of this year and be completed in mid-November of this year.
The Edgewater plant 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.
