Those three scenarios(CAF08, CAF10, CAF14), assumed no CO 2 adder, and only one coal plant was selected. Themodel selected wind for nearly all low-price scenarios, the exception being the “unfavorablewind environment” scenario, CAF08. Scenarios that also included the low coal cost assumption(CAF10, CAF14) had a relatively small amount of wind investment at 400 megawatts. For thescenario with a high coal cost and load growth (CAF06), the fossil fuel investment plant consistedof only CCCT resources at 3,798 megawatts.Table 7.8 – <strong>Resource</strong> Additions for Scenarios with Low Gas/Electricity PricesDSM Coal-SCPC Coal-IGCC GasWindNameplateScenario Cumulative Build Amounts (MW): <strong>2007</strong>-2018CAF04 78 - - 1,823 2,200CAF05 99 - - 125 2,100CAF06 169 - - 3,923 2,400CAF08 129 750 - 1,275 -CAF10 68 750 - 1,225 700CAF14 150 750 - 25 500Average 116 375 - 1,399 1,317With high gas and electricity prices, the model invested heavily in both supercritical pulverizedcoal and wind, except for the scenario with low load growth. For all scenarios, every SCPC optionwas chosen (2,440 megawatts). Gas resources (CCCT and SCCT frame) were selected onlyfor the two scenarios that also had high load growth (CAF03, CAF15). The model selected westIGCC resources in all scenarios, and added all the IGCC units available to it under the highprice/high load growth scenario (CAF03).Table 7.9 – <strong>Resource</strong> Additions for Scenarios with High Gas/Electricity PricesDSM Coal-SCPC Coal-IGCC GasWindNameplateScenario Cumulative Build Amounts (MW): <strong>2007</strong>-2018CAF01 151 2,440 2,002 25 1,100CAF02 78 2,440 500 - 600CAF03 169 2,440 2,510 1,361 3,100CAF07 58 2,440 500 100 3,600CAF09 64 2,440 500 100 3,100CAF15 198 2,440 2,510 1,211 3,100145
