text: Among the factors that make IPM particularly well suited to model multi-emissions control programs are ( 1 ) its ability to capture complex interactions among the electric power , fuel , and environmental markets , ( 2 ) its detail-rich representation of emission control options encompassing a broad array of retrofit technologies along with emission reductions through fuel switching , changes in capacity mix , and electricity dispatch strategies , and ( 3 ) its capability to model a variety of environmental market mechanisms , such as emissions caps , allowances , trading , and banking .
