SSRG recently completed placing concrete foundations as part of infrastructure upgrades at Duke Energy. The upgrades at Duke Energy are a key part of their future dry ash storage program.

Replacing wet with dry

Currently, engineered ponds are the most widely used storage solution for energy byproducts. Today, due to limited water supply and environmental concerns, many energy suppliers are modifying their methods for dealing with ‘bottom ash’, one of the two byproducts from coal-fired power plants, the other being fly ash. While fly ash is traditionally sent to landfills, bottom ash is pumped from the boilers to an on-site ash pond that allows the bottom ash to settle out.

The evolution of dry ash storage is a worldwide trend set to replace wet storage.  In the new facility, Duke Energy will deploy a filtration system that will remove the bottom ash to make it easier to transport to landfills. In doing so, they are leading the charge on this new storage practice.

By working with R.B. Jergens on this project, we are changing the way that Duke Energy deals with hundreds of millions of tons of waste, laying the foundation for a better tomorrow.
