Emission Cap, tons/year

Fig. 9 Emission of the firm in horizon year

Fig. 9 shows the effect of imposing an emission cap (tons/year) on actual emission from the

generators in the portfolio of the investment for firm. These actual emissions are calculated for the

horizon year of the plan (i.e., year-25). It can be seen from the figure that as the emission cap is

increased up to 1.0E+7 tons/year the actual emission of the firm is always at the level of emission cap

imposed, but beyond that the firm’s emission levels are lower than the cap because the firm is bound

by the budget constraint, that does not allow it to produce more energy and associated emission.
