The systems will further reduce the plant’s emissions and ensure compliance with current environmental regulations.
The order value is in the mid double-digit million-euro range and is included in ANDRITZ’s order intake for the third quarter of 2025.
The contract comprises the supply of two state-of-the-art Spray Dry Absorbers (SDAs) for Boiler Units 8 and 9. These systems efficiently remove acid gases, such as sulfur oxides (SO2/SO3) and hydrogen chloride (HCl), which are subsequently collected downstream in the plant’s bag filter devices.
The new systems will complement the two existing ANDRITZ SDAs at Shawnee’s Boiler Units 1 and 4, which have been in operation since 2017, helping TVA meet the stringent requirements of the US Environmental Protection Agency’s Regional Haze Rule.
Harald Prieler, Vice President, ANDRITZ Clean Air Technologies division, states: “We are proud to partner with TVA on this important project and to deliver solutions that contribute to cleaner air for local communities while supporting operational excellence.”
“TVA’s coal fleet, and specifically Shawnee, has played an integral part in supplying low-cost reliable power to the Tennessee Valley for over 70 years,” said Dan Tibbs, TVA Vice President of Projects and Outage Management. “This additional investment in Shawnee helps TVA continue to meet the needs of our growing customer base.”
