What happens to the coal ash Constellation Energy produces in its Maryland power plants?
Constellation Energy’s coal-burning power plants in Maryland produce nearly 800,000 tons of coal ash and byproducts annually. Approximately 60 percent of that ash is used beneficially to produce such products as blasting grit, flowable fill, cement and concrete. Other ash is used as structural fill to reclaim surface mines or to provide backfill for road construction. Constellation Energy’s beneficial use rate is well above the industry average of 43 percent. The remaining ash is properly disposed of in a permitted landfill.
