ALLIANT ENERGY ANNOUNCES 2009 RESULTS AND 2010 GUIDANCE

Net income
  $ 111.0     $ 1.01     $ 288.0     $ 2.61  

EPS for the utility, non-regulated, and parent in 2009 were impacted by a total of $0.36 per share for various non-recurring, non-cash state income tax items. EPS for the parent were also impacted by the one time $1.16 per share of charges related to Alliant Energy’s tender offer for its Exchangeable Senior Notes due 2030 (Notes).  EPS for the utility in 2009 also included the $0.10 per share of non-recurring charges for proposed coal plants, $0.04 per share of regulatory-related credits for the recovery of flood costs and $0.09 per share of non-recurring restructuring charges and impairment of steam assets.  EPS amounts recorded in 2009, excluding these identified non-recurring items are as follows:

   
2009 EPS
   
Charges from tender offer of Notes
   
Non-recurring state income tax items
   
Charges for proposed coal plants and regulatory decision on flood costs
   
Restructuring charges and impairment of steam assets
   
2009 EPS excluding identified non-recurring items
 
Utility
  $ 2.03     $ --     $ 0.32     $ (0.06 )   $ (0.09 )   $ 1.86  
Non-regulated
    0.10       --       (0.05 )     --       --       0.15  
Parent
    (1.12 )     (1.16 )     0.09       --       --       (0.05 )
Alliant Energy
  $ 1.01     $ (1.16 )   $ 0.36     $ (0.06 )   $ (0.09 )   $ 1.96  

Excluding the non-recurring items identified in the table above, Alliant Energy’s 2009 EPS from continuing operations were $1.96 per share which was $0.58 per share lower than 2008.  These lower earnings for Alliant Energy’s utility business were due to the impacts of historically cool summer weather in 2009, higher depreciation and interest expense as a result of planned capital expenditures, lower industrial sales due to unfavorable economic conditions, and income tax benefits resulting from tax audit settlements and known adjustments for future tax audits recognized in 2008.  These items were partially offset by cost saving initiatives and the minimal 2008 flood clean-up and restoration costs incurred in 2009 when compared to 2008, and allowance for funds used during construction due to utility wind project construction.

Lower RMT earnings reduced EPS from Alliant Energy’s non-regulated business by $0.13 per share.  The prolonged economic recession and the credit crisis decreased new construction of wind energy megawatts in the United States by 35-40% in 2009 when compared to 2008.  Lack of wind project financing, lower demand for energy, lower natural gas prices, and the distribution of a large portion of the American Recovery and Reinvestment Act of 2009 cash grants to completed wind energy, all combined to dampen new construction.   Competition among the balance of plant contractors, due to the decreased new construction, also resulted in lower margins at RMT.

Lower earnings at Alliant Energy’s parent company, excluding the non-recurring state income tax items and charges related to the tender offer, reflect lower interest income, higher short-term financing expenses related to the tender offer of the Notes and higher professional expenses.

“The two primary drivers in the year-over-year negative results are weather and the economy,” said Bill Harvey, Alliant Energy Chairman, President, and CEO.  “The negative economic conditions in our utility and non-regulated businesses were too great to overcome, even with our continued commitment to control costs at all levels of the organization.  With normal weather and new retail electric rates in both Iowa and Wisconsin we expect a brighter financial picture in 2010.”

Additional details of 2009 full year and fourth quarter earnings from continuing operations are available in the financial and operating statistical table section at the end of this release.

2010 Earnings Guidance

Alliant Energy’s earnings per share guidance for 2010 is as follows:

Utility
  $ 2.35 – $2.55  
Non-regulated and Parent
    0.10 – 0.20  
Alliant Energy
  $ 2.45 – $2.75  

The guidance does not include the impacts of any non-cash valuation adjustments, future regulatory-related charges or credits resulting from decisions by regulators, reorganization or restructuring charges, future changes in laws or regulations, future adjustments made to deferred tax asset valuation allowances, adverse impacts of pending lawsuits and disputes, or changes in accounting principles that may impact the reported results of Alliant Energy.

Drivers for Alliant Energy’s 2010 earnings guidance include, but are not limited to:
 
·        Anticipated interim rate increases implemented by IPL
 
·        No further significant decline in the economy and resulting implications on utility sales
 
·        Normal weather and operating conditions in its utility service territories
 
·        Ability to recover future purchased power, fuel and fuel-related costs through rates in a timely manner
 
·        Ability of IPL and WPL to recover their operating costs, deferred expenditures and capital expenditures, and to earn a reasonable rate of return in future rate proceedings
 
·        Continuing cost controls and operational efficiencies
 
·        Execution of IPL’s and WPL’s wind projects and environmental expenditure plans
 
·        Ability to utilize federal net operating losses and federal credit carry forwards
 
·        RMT estimated cost controls, market share, and project execution

“In 2010, we expect earnings benefits from returns on IPL’s Whispering Willow - East wind project, which began commercial operation in the fourth quarter of 2009, and construction of phase one of WPL’s Bent Tree wind project during 2010,” said Harvey.  “While we are realizing savings related to corporate cost-control measures, and will continue to seek out ways to mitigate costs to customers, our utilities are planning to file retail rate cases in Iowa, Wisconsin, and Minnesota in 2010.   These rate cases are expected to contribute to our earnings growth by further capturing the benefits of renewable, environmental, and reliability initiatives across the service territory and adjusting rates to reflect our current sales load.”

Projected Capital Expenditures

Alliant Energy currently anticipates capital expenditures for 2010 through 2012 as follows (in millions):

(a) Alliant Energy entered into weather derivatives based on CDDs during the months of June through August in 2008 and HDDs during the months of January through March in 2008 and 2009 and November through December in 2008 to reduce potential volatility on its margins from the impacts of weather.
(b) CDDs and HDDs are calculated using a simple average of the high and low temperatures each day compared to a 65 degree base.  Normal degree days are calculated using a rolling 20-year average of historical CDDs and HDDs.
