The power generation sector is considered as one of the major contributors to air pollution. An optimization model was formulated and written in a general format. The objective of this model is to select the best pollution control strategy for the power generation to reduce NOx to specific level while meeting the electricity demand at minimum cost. The model is illustrated in a case study taken from Ontario Power Generation; Canada. For the NOx case when we consider two options (fuel balancing and switching), it was found that fuel switching is the best option of choice for reduction targets from 5 up to 30%.However, by considering all mitigation options, the result shows that applying SCR technology is the best option to reduce NOx emissions.
