ALLIANT ENERGY ANNOUNCES FIRST QUARTER 2011 RESULTS
REVISES 2011 GUIDANCE
MADISON, Wis. – May 5, 2011 – Alliant Energy Corporation (NYSE: LNT) today announced first quarter U.S. generally accepted accounting principles (GAAP) and non-GAAP consolidated earnings from continuing operations as follows:
| First Quarter | ||||||||
| 2011 | 2010 | |||||||
Adjusted (non-GAAP) Operating Results from Continuing Operations: | ||||||||
Net Income ($ millions) | $ | 75.3 | $ | 50.5 | ||||
Earnings per share (EPS) | $ | 0.68 | $ | 0.45 | ||||
GAAP Earnings from Continuing Operations: | ||||||||
Net Income ($ millions) | $ | 72.2 | $ | 43.4 | ||||
EPS | $ | 0.65 | $ | 0.39 | ||||
Alliant Energy’s 2011 first quarter non-GAAP EPS were $0.68 per share, which was $0.23 per share higher than non-GAAP EPS from continuing operations for first quarter 2010. Earnings for Alliant Energy’s utility business when compared to the first quarter of 2010 were impacted by higher revenues due to implementation of new retail base rates, improved recovery of WPL retail fuel expense, lower capacity payments due to a scheduled nuclear outage, higher production tax credits due to lower than anticipated MISO curtailments, and higher electric and gas sales due to cooler weather in the first quarter of 2011. These positive EPS drivers were partially offset by higher electric transmission service expenses, higher depreciation and operating expenses for the Bent Tree wind project and a formula rate settlement agreement with WPL wholesale customers in the first quarter of 2010.
“I am pleased with the solid financial results produced in the first quarter of 2011,” said Bill Harvey, Alliant Energy Chairman and CEO. “Our focus for the remainder of 2011 includes continued cost controls to enable our utilities to earn their authorized returns; work with various stakeholders in Iowa, Wisconsin, and Minnesota to achieve approval of various applications associated with our strategic plan; and continued review of federal and state environmental regulations and the impact those regulations are expected to have on the future profile of our generating fleet.”
Non-GAAP adjustments, which relate to material charges that are not normally associated with ongoing operations, are provided as a supplement to results reported in accordance with GAAP. Adjusted, or non-GAAP, operating results for the first quarter of 2011 and 2010 do not include the following items (after tax) that were included in reported GAAP earnings:

The following comments further explain selected drivers of earnings performance during the first quarter of 2011 versus 2010:
Electric retail rate increases: On February 2011, Interstate Power and Light Company (IPL) received an order from the Iowa Utilities Board authorizing a final annual retail electric rate increase of $114 million as part of its retail electric rate case in Iowa filed on March 10, 2010. The $114 million annualized rate increase is recovering higher electric transmission service expenses, and a return on the investment and recovery of expenses for the Whispering Willow—East wind project and Lansing Unit 4 environmental controls project, as well as other infrastructure investments. On March 20, 2010, IPL implemented a $119 million annualized interim rate increase as part of this retail electric rate case.
On January 1, 2011, WPL implemented new retail electric rates as a result of its rate case filed in April 2010. The $8 million annualized rate increase includes a $38 million increase in the non-fuel component of rates largely related to return on the investment and recovery of expenses for the Bent Tree wind project, partially offset by a $30 million decrease in the fuel component of rates.
Higher electric transmission service expenses: In January 2011, the IUB approved IPL’s proposal to implement a transmission cost recovery rider for electric transmission service expenses. Effective February 25, 2011, electric transmission service expenses were removed from base rates and billed to IPL’s Iowa electric retail customers through the transmission cost rider.
Retail fuel-related impacts at WPL: On January 1, 2011, new Wisconsin fuel rules became effective, which authorize WPL to defer incremental under- or over-collection of fuel-related costs from electric retail customers that are outside a range of plus or minus 2% of forecasted fuel-related costs used to set rates. During the first quarter of 2011, WPL’s fuel-related costs exceeded the amounts recovered in retail electric rates by $0.02 per share. Under the new Wisconsin fuel rules, WPL’s exposure to under-collection of fuel-related costs is limited to approximately $0.03 per share for all of 2011 provided WPL’s earned return on equity (ROE) does not exceed its authorized ROE. During the first quarter of 2010, actual fuel-related costs exceeded amounts recovered in retail electric rates by $0.05 per share.
Impairment of wind site in Wisconsin: In 2009, WPL purchased development rights to an approximately 100 megawatt (MW) wind site in Green Lake and Fond du Lac counties in Wisconsin. Due to events in the first quarter of 2011 resulting in uncertainty regarding the wind siting requirements in Wisconsin and increased risks with permitting this wind site, WPL determined it would be difficult to effectively use the site for wind development. As a result, WPL recognized an impairment in the first quarter of 2011 of $5 million for the entire capitalized costs incurred for this site.

2011 Earnings Guidance
Alliant Energy is revising its 2011 earnings guidance, which excludes an impairment charge associated with the wind site in Wisconsin discussed throughout this release. The revision is largely due to the weather impacts on electric and gas sales in the first quarter of 2011.
| Current | Previous | |||
Utility | $2.65 – $2.80 | $2.60 – $2.80 | ||
Non-regulated and Parent | 0.10 – 0.20 | 0.10 – 0.20 | ||
Alliant Energy | $2.75 – $3.00 | $2.70 – $3.00 | ||
The 2011 earnings guidance does not include the impacts of any non-cash valuation adjustments, regulatory-related charges or credits, reorganization or restructuring charges, changes in laws or regulations, adjustments made to deferred tax asset valuation allowances, pending lawsuits and disputes, federal and state income tax audits and other Internal Revenue Service proceedings or changes in accounting principles that may impact the reported results of Alliant Energy.
Drivers for Alliant Energy’s 2011 earnings guidance include, but are not limited to:
| • | Stable economy and resulting implications on utility sales |
| • | Normal weather and operating conditions in its utility service territories |
| • | Ability of IPL and WPL to earn their authorized rate of return |
| • | Continuing cost controls and operational efficiencies |
| • | Execution of IPL’s and WPL’s capital expenditure plans |
