New technology and emission controls

In addition to the existing emission controls already operating across our power plants, we installed extensive emissions control upgrades to further reduce sulfur dioxide and nitrogen oxide emissions, as well as state-of-the-art technology to control mercury and fine particulate matter.

Mill Creek

  • Constructed new, replacement flue gas desulfurization systems, also known as scrubbers
  • Installed fabric-filter baghouse systems
  • Added Dry Sorbent Injection (DSI) systems

Cane Run

  • Constructed Kentucky’s first natural gas combined-cycle generating unit  

Trimble County

  • Unit 2, known as TC2, is among the cleanest coal-fired power plants in the U.S. This unit is equipped with technologies that meet the EPA’s Mercury and Air Toxics Standards, including flue gas desulfurization and SCR technology.
  • Installed fabric-filter baghouse systems for Unit 1
  • Added Dry Sorbent Injection (DSI) systems
  • Installed fabric-filter baghouse systems; dry and wet electrostatic precipitators; and Dry Sorbent Injection (DSI) systems.

Ghent

  • Installed fabric-filter baghouse systems
  • Added Dry Sorbent Injection (DSI) systems

E.W. Brown

  • Installed fabric-filter baghouse systems and added Dry Sorbent Injection (DSI) systems to Unit 3
