MARSHALLTOWN, Iowa, June 26 /PRNewswire-FirstCall/ -- Interstate Power and Light Company (IPL), a wholly-owned subsidiary of Alliant Energy Corporation (NYSE: LNT), announced today that the Sutherland Generating Station Units 1, 2 and 3, located in Marshalltown, Iowa, are back online two weeks after the facility was intentionally taken offline due to flooding concerns in the community and along the Iowa River. The power plant's three units consist of approximately 144 megawatts. (Logo: http://www.newscom.com/cgi-bin/prnh/20020405/LNTLOGO) Storms and the subsequent flooding impacted approximately 2,600 customers in the Marshalltown area. The Iowa River crested approximately four feet above flood stage on June 10 and June 13, 2008. The Sutherland Generating Station, located approximately one-quarter mile from the Iowa River, did receive minor damage to the facility when water levels in the power plant's basement reached approximately four inches. The power plant's main turbine floor was not affected. After the floodwaters receded, crews worked to assess, repair and inspect the facility prior to bringing the facility back online. The power plant's electrical system and motors were inspected and repaired as necessary. Floodwaters caused moderate damage to the facility's railroad tracks, train unloading operations, coal handling system, fuel tanks for combustion turbines. Flood levels reached approximately two feet in the coal yard, and all underground pits were full of water. Major restoration work was completed on the railroad tracks and train unloading operations. The facility started receiving and unloading coal trains on June 23, 2008. "Our employees rose to the challenge of bringing the power plant back online as quickly and safely as possible," stated William Ku -- plant manager -- Sutherland Generating Station. "Whether it was sandbagging as the floodwaters rose or helping in the clean-up and repair efforts as the floodwaters receded, our employees did an outstanding job of meeting these challenges. In the coming weeks, we will continue to make repair and rebuild the facility's infrastructure impacted by the flooding." The company expects to have a flood damage cost estimate after restoration efforts are complete across its Iowa service area. "We are extremely proud of our employees' efforts to get the Sutherland Generating Station back online," said Tim Bennington -- vice president -- Generation. "Their efforts made a difference as a fully operational Sutherland Generating Station strengthens the reliability of our electric system as we enter the summer electric demand period." "This was a team effort and our company appreciates the City of Marshalltown's support during these unprecedented times," stated Tom Aller -- president -- IPL. "Our company is strongly committed to the original Sutherland Generating Station Unit 4 site plan. The new power plant's site is located above the 500 year flood plain. However, in the coming weeks, our crews will assess where the flooding occurred and make any modifications to the proposed site as appropriate. The new power plant site was not significantly impacted by the historic floodwaters in the community and reaffirms our decision to locate the new facility in Marshalltown. We remain steadfast in our commitment to building a hybrid generating facility in Marshalltown that we expect will provide all of our electric customers with safe, reliable and environmentally responsible electric service."
