The need for electric power is increasing day by day in the developing world. Power generation units using fossil fuel cause environmental problems. Therefore, environmental pollution must be taken into consideration while solving optimum power dispatch problems. This kind of problems considering the environmental pollution are called environmental economic power dispatch problems. In this study, multiobjective environmental economic power dispatch problem has been transformed into single-objective optimization problem by using conic scalarization method (CSM). Genetic algorithm (GA) method has been used for the solution of the scalarized problem. The samples handled for practice are lossy power systems formed of generation units with convex and non-convex piecewise fuel cost functions. In the sample problems the best solution values belonging to total fuel cost and NOx emission values (pareto optimal values) have been obtained for different weight values and the results have been discussed.
