"Our company is delivering on its commitment to meet our current customers and future generations of customers demand with safe, reliable and environmentally responsible energy," says Tom Aller, president of IPL. "The investments in the Lansing Generating Station will create economic development opportunities while mitigating the facility's impact upon our environment."

Construction is expected to begin this summer to install a selective catalytic reduction system and low nitrogen oxide (NOx) burners. The selective catalytic reduction (SCR) system is expected to be an $85 million investment. IPL expects the technologies to remove more than 90 percent, or more than 3,700 tons, of the NOx emissions from the Lansing Generating Station Unit 4 per year. Babcock Power Environmental Inc. will perform the engineering and procurement of the SCR system. Enerfab and their subcontractors will perform the construction on the project.

The SCR system and NOx burner projects are expected to require a peak workforce of approximately 100 workers with a total number of labor hours of approximately 250,000.

In addition, IPL has filed plans with the Iowa Utilities Board for the installation of a baghouse, which is designed to capture a minimum of 90 percent of the mercury emissions from the Lansing Generating Station Unit 4.

IPL expects the SCR and baghouse projects to be completed by late 2009.

"We are proud to play a part in positioning our service area for a bright energy future," adds Aller. "Our investments in emissions reduction technologies, combined with our pursuit of additional baseload and renewable energy generation and commitment to energy conservation provide a balanced approach for our state's economy and environment. We are also extremely appreciative of the strong energy partnership between our company and the community of Lansing."
