The emission-constrained dispatch problem is formulated as a nonlinear constrained minimization problem. Consequently, the solution to the problem gives a continuous relationship between cost and annual emission for SO2. It is shown that the power system should be operated at the same value of the Lagrangian multiplier, η, in every hour where η is defined as ∂(production cost)/∂(hourly emission). The addition of η as a proxy cost of emission in the economical dispatch procedure achieves this goal. It is shown that the emission-η relationship obtained by NLCM procedure can be used to make operating decisions, in particular, the trading of allowances
