The impact of the wind and CCCT additions is evidentfrom the emissions drop from 2011 through 2012 for portfolios RA14, RA15, and RA16. Theincreasing annual emissions after this point are attributable to the addition of the Wyoming supercriticalpulverized coal resource in 2014 and an increase in front office transactions. The significantemissions drop in 2019 for all the portfolios is caused by the addition of CCCT-basedgrowth stations, which replace the acquisition of front office transactions.For the $61 adder case, the large CO 2 emission decreases in 2013 through 2015 are due to thephasing in of the adder, which starts in 2010 but ramps up significantly in 2014 and 2015.Figure 7.24 – Annual CO 2 Emission Trends, 2007-2026, ($8 CO 2 Adder Case)(Generation plus the net indirect effect of wholesale purchases and sales)65,000$8/Ton CO 2 adder has a phase-inperiod from 2010-201260,00055,000(Tons 000)50,00045,00040,0002007 2008 2009 2010 2011 2012 2013 2014 2015 2016 2017 2018 2019 2020 2021 2022 2023 2024 2025 2026RA13 RA14 RA15 RA16 RA17194
