Wisconsin Power and Light Co. told the Public Service Commission of Wisconsin in an April 29 quarterly update that construction of the new Dry Flue Gas Desulfurization system for the coal-fired Edgewater Unit 5 is due for completion in September, with testing after that and system commissioning in November of this year.
In June 2013, the commission approved 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 $413,710,000, excluding AFUDC. As of this update, the project is currently forecasted to be completed for approximately $246,300,000, excluding AFUDC.
This is a circulating fluidized bed (CFB) scrubber. At the end of March 2016, the project was on schedule and 97% complete.
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.
