Dairyland Power Cooperative plans to burn 2,337,960 tons of coal in 2016 at its three coal-fired generating facilities, with all of it being sub-bituminous coal out of the Wyoming end of the Powder River Basin.
Dairyland on Sept. 30 filed with the Public Service Commission of Wisconsin its annual projections for SO2 emissions, with these particular projections covering calendar 2016.
The statistics by plant/unit are:
- Genoa Unit 3 (309 MW), this is a cycling unit that runs hardest during high power demand periods, 899,414 tons of projected 2016 coal burn, with coal coming from Arch Coal‘s Black Thunder mine.
- John P. Madgett (391 MW), cycling, 982,543 tons of 2016 coal burn, sourced from Peabody Energy‘s North Antelope Rochelle mine and from Black Thunder.
- Weston Unit 4 (153 MW Dairyland share of co-owned unit), baseload, 456,003 tons of 2016 coal burn (based on Dairyland’s share of the unit and its coal burn), coal from Cloud Peak Energy‘s Antelope mine and from North Antelope Rochelle.
The filing doesn’t offer any coal burn figures for 2017 or 2018, but it does show projected SO2 emissions for these plants in those years, with those emissions roughly around the 2016 figures. So these units would apparently see steady-state operations over the 2016-2018 period.
Of note is that the Wisconsin Department of Natural Resources is out for comment until Oct. 25 on various air permit changes covering the co-located Alma and J.P. Madgett plants of Dairyland, with those changes in part covering the retirements of the five coal units at Alma. Historically, the Alma site consisted of six pulverized coal-fired boilers located in two separate buildings, with one of those boilers making up the J.P. Madgett plant.
Alma 1, Alma 2 and Alma 3 were retired from service in early 2012. Alma 4 and Alma 5 were retired in the fall of 2014.
