An Iowa utility company plans to phase out several of its coal-fired power plants in the near future.
Interstate Power and Light Co. – a subsidiary of Alliant Energy – announced on Wednesday that it will either close or convert to natural gas five of its coal plants while an additional two plants will be equipped with pollution control technology. The cost for these projects is estimated at $620 million. Wednesday’s announcement marks the 200th closure of a coal plant nationwide over the last five years.
The Sierra Club, the state of Iowa, and other local and federal agencies sued Interstate Power and Light alleging the company was in violation of the Clean Air Act. In addition to the closures and upgrades to its facilities, Interstate Power and Light has also agreed to a pay a $1.1 million civil penalty within 30 days of the settlement. The company will also spend an additional $6 million on other environmental projects including the development of solar facilities, the replacement of traditional utility bucket trucks with hybrid trucks, and the development or expansion of anaerobic digesters.
“For several years, we have been executing a plan to create cleaner and more efficient ways to generate energy for our customers,” Alliant Energy Iowa utility President Doug Kopp said in a press release. “Iowans are already seeing the benefits of our work, and our next projects will deliver even more clean-energy solutions.”
Emission reduction projects will take place on two of the company’s largest facilities in Lansing and Ottumwa while smaller power stations in Burlington and Cedar Rapids will convert to natural gas. Alliant generating stations in Clinton, Dubuque, and Marshalltown have already transitioned to natural gas.
