Ameren has invested more $400 million in environmental improvements at Duck Creek.
- A selective catalytic reduction system was installed at the Duck Creek Energy Center. Designed to significantly reduce nitrogen oxide (NOx) emissions, selective catalytic reduction breaks down NOx present in the exhaust gases into elemental water.
- The company replaced the old scrubber with a new scrubber system, reducing sulfur dioxide (SO2) emissions by more than 90%.
- A new precipitator was also installed at Duck Creek. Electrostatic precipitators offer an efficient way to capture particulates before they go into the atmosphere.
- These initiatives follow the installation of a range of combustion control technologies, like low-NOx burners that reduce NOx emissions at many of Ameren’s Illinois generating facilities.
- The company also installed new technology to optimize boiler performance and improve air flow and coal combustion within the boiler to reduce carbon monoxide emissions.
Preservation and Waste Management
Many of Duck Creek’s 9,000 acres are dedicated to wildlife and habitat preservation. At the heart of the conservation area is a 1,800-acre cooling lake created by an earthen dam across Duck Creek. The area is an ideal haven for an assortment of wildlife, flora and fauna.
Duck Creek utilizes a closed-loop system for the SO
2 scrubber that minimizes water consumption and helps to preserve the natural landscape.
