Power Plant Air Quality Decisions Aids Power Plants in Making Environmental Decisions


A utility had to quickly address ways to reduce air pollution on four large boilers based on an EPA disapproval of the State plan. The utility opted to use the free Power Plant Air Quality Decisions (PPAQD) to help make the decision. This included access to a comprehensive intelligence system with decisively classified options plus recorded webinars.

Because of the potential size of the investment ($700 million), McIlvaine elected to conduct three focused webinars to help the utility apply the system. Suppliers contributed new information for the system which has proved to be very useful. This information was reviewed during the sessions in a crowd decision making mode. The decision options were then revised to reflect new alternatives and new values for existing routes.

The utility has not yet made a final decision on the solution, but at this point, the most likely choice is one that no one would have predicted at the start of the process. One reason is that some of the application knowledge has been limited to the cement, glass and waste-to-energy applications and was not known to the power industry. In addition, some of the processes, when applied to other pollutants, have proved successful in coal-fired power. So this was the first time it was realized that they were equally applicable to the target pollutant. The third reason was that new developments make this option much more attractive.

The staff of the utility has impressive resumes and knowledge of air pollution control equal to any power generator. The fact that a large U.S. utility can benefit from the system leads to the conclusion that any small power plant or offshore power plant will derive even more benefit from use of the system.

The world s relevant information is doubling every few years while an individual s ability to assimilate it remains fixed. Systems such as Power Plant Air Quality Decisions become increasingly necessary.
