Emissions control technologies make up approximately 40 percent of the cost of the new Cliffside units. These technologies will be capable of removing approximately:

  • 99.9 percent of the fly ash emissions
  • 99 percent of the sulfur dioxide emissions
  • 96 percent of the sulfate emissions
  • 90 percent of the nitrogen oxide emissions
  • 90 percent of the mercury emissions.

The modernization of the Cliffside site will increase the plant output by 80 percent  from 760 megawatts to 1,360 megawatts, and also reduce the site's overall emissions in most categories. This is made possible by the retirements of the much less efficient Cliffside units 1-4, the sulfur dioxide scrubber planned for Cliffside unit 5 and the state-of-the-art emissions controls used with the modern units.
