SSRG recently completed placing concrete foundations as part of the infrastructure upgrades at Duke Energy. The upgrades are a key part of their future dry ash storage program. The evolution of dry ash storage is becoming a worldwide trend that looks to replace wet storage with dry solutions. Currently, engineered ponds are the most widely used storage solution. 

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. 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 and laying the foundation for a better tomorrow.
