Converting to Dry Management

We first embraced the concept of dry management for coal combustion residuals in 2008. Projects of this scope and size require many years for design, planning, permitting, contracting, and execution. As a result of our early transition in this direction, we’re in the final stages of our plans.

  • We operate dry CCR handling processes at all of our power plants.
  • We operate dry storage systems at our Mill Creek, E.W. Brown, and Ghent power plants, and we anticipate our new dry storage facility at Trimble County will be complete in the spring of 2022.
  • Once processed, the dry CCR materials are stored on site at our power plants if not beneficially used offsite for materials such as concrete, wallboard or fertilizer.
  • As part of our plans, we’ve also built new, state-of-the-art process-water treatment facilities at all of our power plants. 

Making everyday products

We coordinate the sale of our CCR by-product materials to third-party companies for their production processes. 

Since 2003, more than 23 million tons of CCR materials generated at our plants have been beneficially used to make products like concrete, cement, porcelain tile, wallboard and roofing shingles.

100% of the revenue generated through these sales goes back to our customers as a credit primarily calculated into the environmental surcharge on bills each month. Since 2016, beneficial use has generated more than $15 million in savings for LG&E and KU customers.

Once processed, the dry materials will be stored on site at our power plants or beneficially reused offsite for materials such as concrete, wallboard or fertilizer.
