According to the PPA for Cogeneration, power generator regular maintenance should be arranged in the non-summer period (From Oct. 1st to May 31st), which is the air pollution season in Taiwan. Therefore, the power generated by Cogeneration decline sharply in air pollution season. For further comparison between the period of air and non-air pollution season of power generation, as below.
