IN THE KNOW: Visible Work Crystal River Coal-Fired Units 4 & 5

March 1, 2019

Good afternoon, 

I want to inform you of additional work underway at our Crystal River Energy Complex that could generate interest from the community and media. 

During the next year, the Crystal River Energy Complex skyline from the Gulf of Mexico will change as crews remove the two original 600-foot tall stacks at Crystal River coal-fired units 4 and 5. 

Crawling from the top of the stack to the bottom, crews will use a machine called a Mende Spider to slowly remove the concrete and rebar that forms the exterior shell of the stacks until nothing is left. Crews will then recycle the materials. 

During the next few months, anglers, boaters and water enthusiasts will see gradual physical changes to the stacks from the Gulf of Mexico. Once the project is completed in late 2019, the two stacks will be gone (see 1st photo).

The two original stacks have not been used since 2010 following the $1.4 billion investment in pollution-control equipment at the station. Taking down the stacks is part of Duke Energy’s strategy to remove infrastructure no longer in use, which reduces maintenance and inspection costs.  

Though the skyline will eventually look different, the iconic silhouette of the hourglass-shaped cooling towers and main stack will remain visible. Crystal River units 4 and 5 are among the cleanest coal-fired units in the country, and these components release clean water vapor similar to fog.  

The project is not related to the eventual demolition of Crystal River coal-fired units 1 and 2, which formally retired on Dec. 31, 2018, or activities at the Crystal River Nuclear Plant. 

Should you have questions, don’t hesitate to contact me.
