          invited to attend the Annual Meeting and are entitled to and requested
          to vote on the proposals described in this proxy statement.


2. Q: What is Alliant Energy Corporation?

     A:   The Company is a public  utility  holding  company whose primary first
          tier subsidiaries include Interstate Power and Light Company ("IP&L"),
          Wisconsin Power and Light Company ("WP&L"),  Alliant Energy Resources,
          Inc. ("AER") and Alliant Energy  Corporate  Services,  Inc.  ("Alliant
          Energy Corporate Services").


3. Q: Who is entitled to vote at the Annual Meeting?

     A:   Only  shareowners of record at the close of business on April 1, 2004,
          are  entitled to vote at the Annual  Meeting.  As of the record  date,
          _________  shares  of the  Company's  common  stock  were  issued  and
          outstanding. Each shareowner is entitled to one vote for each share of
          the Company's common stock held on the record date.


4. Q: What may I vote on at the Annual Meeting?

     A:   You may vote on:

          .    The election of five nominees to serve on the Company's  Board of
               Directors,  one  nominee  for a term  expiring at the 2006 Annual
               Meeting of  Shareowners  and four nominees for terms  expiring at
               the 2007 Annual Meeting of Shareowners; and

          .    A  proposal  to  amend  the   Company's   Restated   Articles  of
               Incorporation  to  increase  the number of  authorized  shares of
               common stock of the Company from 200 million to 240 million.

5. Q: How does the Board of Directors recommend I vote?

     A:   The Board of Directors  recommends  that you vote your shares FOR each

          Company's Restated Articles of Incorporation to increase the number of
          authorized shares of common stock of the Company.

6. Q: How can I vote my shares?

     A:   You may vote either in person at the Annual Meeting or by appointing a
          proxy.  If your  shares are  registered  directly  with the  Company's
          Shareowner Services Department, then you have three options to appoint
          a proxy:

          .    By telephone;
          .    By Internet; or
          .    By mailing the proxy card.

          Please refer to the  instructions  included on your proxy card to vote
     by proxy.  If you hold your shares  through a bank,  broker or other record
     holder,  then  you may  vote by the  methods  your  bank  or  broker  makes
     available,  in which case the bank or broker will include instructions with
     this  proxy  statement.  If you  vote  by the  Internet,  then  you  should
     understand that there might be costs  associated  with  electronic  access,
     such  as  usage  charges  from  Internet  access  providers  and  telephone
     companies that you must bear. Appointing a proxy will not affect your right
     to vote your shares if you attend the Annual  Meeting and desire to vote in
     person.

7. Q: How are votes counted?

     A:   In the  election of  directors,  you may vote FOR all of the  director
          nominees  or your vote may be  WITHHELD  with  respect  to one or more
          nominees. With respect to the proposal to amend the Company's Restated
          Articles  of  Incorporation,  you may vote FOR or  AGAINST  or you may
          ABSTAIN from  voting.  If you return your signed proxy card but do not
          mark the boxes showing how you wish to vote, your shares will be voted
          FOR all listed  director  nominees  and FOR the  proposal to amend the
          Company's Restated Articles of Incorporation.


                                      -2-


8. Q: Can I change my vote?

     A:   You have the right to revoke  your proxy at any time before the Annual
          Meeting by:

          .    Providing written notice to the Corporate Secretary of the
               Company and voting in person at the Annual Meeting; or
          .    Appointing a new proxy prior to the start of the Annual Meeting.

          Attendance  at the  Annual  Meeting  will not  cause  your  previously
     appointed  proxy to be  revoked  unless  you  specifically  so  request  in
     writing.

9. Q: What shares are included on the proxy card(s)?

     A:   Your proxy card(s)  covers all of your shares of the Company's  common
          stock,  including  any shares held in your account under the Company's
          Shareowner  Direct Plan. For present or past  employees of IP&L,  your

          Inc. Employee Stock Ownership Plan.

          Alliant Energy Corporation 40l(k) Savings Plan voted?

          separate form of proxy from the trustee of the Plan.

11. Q: What does it mean if I get more than one proxy card?

     A:   If your  shares are  registered  differently  and are in more than one
          account,  then you will receive  more than one proxy card.  Be sure to
          vote all of your accounts to ensure that all of your shares are voted.
          The Company encourages you to have all accounts registered in the same
          name and  address  (whenever  possible).  You can  accomplish  this by
          contacting  the  Company's   Shareowner  Services  Department  at  the

          statement.

          indicate  whether you plan to attend the Annual Meeting when voting by
          telephone or Internet,  or you may indicate on the enclosed proxy card
          your  intention  to attend the Annual  Meeting and return it with your
          signed proxy.

13. Q: How will voting on any other business be conducted?

     A:   The Board of Directors of the Company does not know of any business to
          be  considered  at the  Annual  Meeting  other  than the  election  of
          directors and the proposal to amend the Company's Restated Articles of
          Incorporation.  If any other  business  is properly  presented  at the
          Annual Meeting,  your proxy gives Erroll B. Davis,  Jr., the Company's
          Chairman and Chief  Executive  Officer,  and F. J. Buri, the Company's
          Corporate  Secretary,  authority  to  vote on such  matters  at  their
          discretion.

16. Q: How can I access future proxy materials and annual reports on the
          Internet?

     A:   The Company is offering you the  opportunity  to consent to access its

                                      -3-


          If you are a  shareowner  of record,  you can consent to access  these
     materials electronically to allow the Company to save the cost of producing
     and mailing these  materials by marking the  appropriate  box on your proxy
     card or by  following  the  instructions  provided  if you  vote  over  the
     Internet or by telephone. If you consent to access these materials over the
     Internet,  then you will  receive  a proxy  card in the mail next year with
     instructions  containing  the Internet  address to access those  materials.
     However,  you will not receive those proxy  materials and the annual report
     by mail. Your consent will remain in effect unless it is revoked by calling
     or writing the Company's  Shareowner  Services Department at the Shareowner
     Information  Numbers  shown at the front of this proxy  statement or at the
     address of the Company shown on the first page of this proxy statement.

          If you hold  your  stock  through a bank,  broker  or other  holder of
     record,  please  refer  to the  information  provided  by that  entity  for
     instructions  on how to elect to view future  proxy  statements  and annual
     reports over the Internet.

          If you consent to electronic access,  then you will be responsible for
     your usual Internet-related charges (e.g., on-line fees, telephone charges)
     in connection with  electronic  viewing and printing of proxy materials and
     annual reports.  The Company will continue to distribute  printed materials
     to shareowners who do not consent to access these materials electronically.

17. Q: When are shareowner proposals for the 2005 Annual Meeting due?

     A:   All  shareowner  proposals  to be  considered  for  inclusion  in  the
          Company's  proxy  statement for the 2005 Annual  Meeting,  pursuant to
          Rule 14a-8 under the Securities  Exchange Act of 1934 ("Rule  14a-8"),
          must be  received  at the  principal  office of the Company by Dec. 7,
          2004.

          In addition,  any  shareowner who intends to present a proposal at the
     2005 Annual  Meeting  must comply  with the  requirements  set forth in the
     Company's Bylaws. The Company's Bylaws state,  among other things,  that to
     bring business  before an annual  meeting,  a shareowner  must give written
     notice that  complies  with the Bylaws to the  Corporate  Secretary  of the
     Company not later than 45 days in advance of the first  annual  anniversary
     of the date the Company first mailed its proxy statement to shareowners for
     the prior  year's  annual  meeting.  Accordingly,  the Company must receive
     notice of a  shareowner's  proposal  submitted  other than pursuant to Rule
     14a-8 no later than Feb. 20, 2005. If the notice is received after Feb. 20,
     2005,  then the notice will be  considered  untimely and the Company is not
     required to present such proposal at the 2005 Annual Meeting.  If the Board
     of Directors chooses to present a proposal submitted other than pursuant to
     Rule  14a-8 at the 2005  Annual  Meeting,  then  the  persons  named in the
     proxies  solicited  by the Board for the 2005 Annual  Meeting may  exercise
     discretionary voting power with respect to such proposal.

18. Q: Who are the independent auditors of the Company and how are they
          appointed?

     A:   Deloitte & Touche LLP audited the financial  statements of the Company
          for the year ended Dec. 31, 2003. Representatives of Deloitte & Touche
          LLP are expected to be present at the meeting with the  opportunity to
          make a statement  if they so desire and to be  available to respond to
          appropriate  questions.  The Audit Committee of the Board of Directors
          expects to appoint the Company's  independent  auditors for 2004 later
          in the year.

          On June 12, 2002,  the Board of  Directors  of the  Company,  upon the
     recommendation of the Audit Committee, dismissed Arthur Andersen LLP as the
     Company's independent auditors and contracted with Deloitte & Touche LLP to
     serve as its independent  auditors for 2002. Arthur  Andersen's  reports on
     the Company's consolidated financial statements for the year ended Dec. 31,
     2001  did  not  contain  an  adverse  opinion,  disclaimer  of  opinion  or
     qualification or modification as to uncertainty,  audit scope or accounting
     principles.  During the year ended Dec. 31, 2001 and the subsequent interim
     period, there were no disagreements between the Company and Arthur Andersen
     on any matter of accounting  principles or practices,  financial  statement
     disclosure or auditing scope or  procedures,  which  disagreements,  if not
     resolved to the  satisfaction of the accounting  firm, would have caused it
     to  make a  reference  to the  subject  matter  of  such  disagreements  in
     connection with its reports.

19. Q: Who will bear the cost of soliciting proxies for the Annual Meeting
          and how will these proxies be solicited?

     A.   The  Company  will pay the cost of  preparing,  assembling,  printing,
          mailing and  distributing  these proxy  materials.  In addition to the
          mailing of these proxy materials, the solicitation of proxies or votes
          may be made in person, by telephone or by electronic  communication by
          the  Company's  officers  and  employees  who  will  not  receive  any
          additional compensation for these solicitation activities. The Company
          will pay banks,  brokers,  nominees and other  fiduciaries  reasonable
          charges and expenses  incurred in  forwarding  the proxy  materials to
          their  principals.  The Company  has  retained  Georgeson  Shareholder
          Communications Inc. to aid in the solicitation at an estimated cost of
          $6,000 plus reimbursable out-of-pocket expenses.

20. Q: If more than one shareowner lives in my household, how can I obtain
          an extra copy of the Company's 2003 Annual Report and this proxy
          statement?

     A.   Pursuant to the rules of the SEC,  services that deliver the Company's
          communications  to  shareowners  that hold their stock through a bank,
          broker or other  holder of record may deliver to multiple  shareowners
          sharing the same  address a single copy of the  Company's  2003 Annual
          Report and proxy statement.  Upon written or oral request, the Company
          will mail a  separate  copy of the 2003  Annual  Report  and/or  proxy
          statement to any shareowner at a shared address to which a single copy
          of each  document  was  delivered.  You may notify the Company of your
          request  by  calling  or writing  the  Company's  Shareowner  Services
          Department at the Shareowner Information Numbers shown at the front of
          this proxy  statement  or at the address of the  Company  shown on the
          first page of this proxy statement.

                             ELECTION OF DIRECTORS

At the Annual Meeting,  one director will be elected for a term expiring in 2006
and four  directors will be elected for terms expiring in 2007. The nominees for
election as recommended by the Nominating and Governance  Committee and selected
by the Board of Directors are: Ann K. Newhall,  for a term expiring in 2006; and
Michael L. Bennett,  Jack B. Evans, David A. Perdue and Judith D. Pyle for terms
expiring in 2007. Each of the nominees is currently serving as a director of the
Company.  Each person  elected as a director will serve until the Annual Meeting
of  Shareowners of the Company in 2006 or 2007, as the case may be, or until his
or her successor has been duly elected and qualified.


Directors  will be  elected  by a  plurality  of the votes  cast at the  meeting
(assuming  a quorum  is  present).  Consequently,  any  shares  not voted at the
meeting will have no effect on the election of directors.  The proxies solicited
may be voted for a  substitute  nominee or nominees if any of the  nominees  are
unable to serve,  or for good  reason  will not  serve,  a  contingency  not now
anticipated.


Brief  biographies  of the director  nominees and continuing  directors  follow.
These  biographies  include their age (as of Dec. 31, 2003), an account of their
business   experience   and  the  names  of  publicly  held  and  certain  other
corporations  of which they are also directors.  Except as otherwise  indicated,
each  nominee and  continuing  director  has been  engaged in his or her present
occupation for at least the past five years.

                      MEETINGS AND COMMITTEES OF THE BOARD


The  Board  of  Directors  has  standing  Audit;   Compensation  and  Personnel;
Environmental,  Nuclear,  Health and  Safety;  Nominating  and  Governance;  and
Capital Approval  Committees.  The Board of Directors has adopted formal written
charters for each of the Audit,  Compensation and Personnel,  and Nominating and
Governance  Committees,   which  are  available  on  the  Company's  website  at
www.alliantenergy.com/investors  under the "Corporate  Governance"  caption. The
following  is a  description  of each of  these committees:


Audit Committee
- ----------------

The Audit  Committee  held  seven  meetings  in 2003.  The  Committee  currently
consists of J. B. Evans (Chair),  A. B. Arends, M. L. Bennett,  S. B. McAllister
and D. A. Perdue. Each of the members of the Committee is independent as defined
by the New York Stock Exchange  ("NYSE")  listing  standards and SEC rules.  The
Board of  Directors  has  determined  that Mr.  Evans and two  additional  Audit
Committee members qualify as "audit committee  financial  experts" as defined by
SEC rules.  The Audit Committee is responsible for assisting Board oversight of:
(1) the  integrity of the  Company's  financial  statements;  (2) the  Company's
compliance with legal and regulatory requirements; (3) the independent auditors'
qualifications  and  independence;  and (4)  the  performance  of the  Company's
internal audit function and  independent  auditors.  The Audit Committee is also
directly responsible for the appointment,  retention, termination,  compensation
and oversight of the Company's independent auditors.

Compensation and Personnel Committee
- -------------------------------------

The  Compensation  and  Personnel  Committee  held three  meetings in 2003.  The
Committee currently consists of J. D. Pyle (Chair), A. B. Arends, M. L. Bennett,
S. B.  McAllister  and D. A.  Perdue.  Each of the members of the  Committee  is
independent as defined by the NYSE listing standards. This Committee reviews and
approves  corporate  goals and objectives  relevant to Chief  Executive  Officer
("CEO")  compensation,  evaluates  the  CEO's  performance  and  determines  and
approves as a committee or together  with the other  independent  directors  the
CEO's compensation  level based on the evaluation of the CEO's  performance.  In
addition,  the  Committee  has  responsibilities  with respect to the  Company's
executive   compensation  and  incentive  programs  and  management  development
programs.

Environmental, Nuclear, Health and Safety Committee

2003. The Committee currently consists of R. W. Schlutz (Chair), K. C. Lyall, A.
K. Newhall, J. D. Pyle and A. R. Weiler. The Committee's responsibilities are to
review  environmental  policy and  planning  issues of interest to the  Company,
including matters involving the Company before environmental regulatory agencies
and compliance with air, water and waste regulations. In addition, the Committee
reviews  policies  and  operating  issues  related  to  the  Company's   nuclear
generating   station   investments,   including   planning   and   funding   for
decommissioning  of the plants.  The  Committee  also reviews  health and safety
related  policies,  activities and operational  issues as they affect employees,
customers and the general public.

                                      -9-


Nominating and Governance Committee
- -------------------------------------

The  Nominating  and  Governance  Committee  held  four  meetings  in 2003.  The
Committee currently consists of A. R. Weiler (Chair), K. C. Lyall, A. K. Newhall
and R. W.  Schlutz.  Each of the  members of the  Committee  is  independent  as
defined by the NYSE listing standards. This Committee's responsibilities are to:
(1) identify individuals qualified to become Board members,  consistent with the
criteria  approved by the Board, and to recommend  nominees for directorships to
be filled by the Board or shareowners;  (2) identify and recommend Board members
qualified to serve on Board committees; (3) develop and recommend to the Board a
set of corporate governance principles;  (4) oversee the evaluation of the Board
and the  Company's  management;  and (5) advise the Board with  respect to other
matters relating to corporate governance of the Company.

In making  recommendations  to the  Company's  Board of Directors of nominees to
serve as directors,  the Nominating  and Governance  Committee will examine each
director  nominee on a  case-by-case  basis  regardless of who  recommended  the
nominee and take into  account all factors it considers  appropriate,  which may
include strength of character, mature judgment, career specialization,  relevant
technical  skills or  financial  acumen,  diversity  of  viewpoint  and industry
knowledge. However, the Committee believes that, to be recommended as a director
nominee, each candidate must:

          .    display the highest personal and professional  ethics,  integrity
               and values.

          .    have the ability to exercise sound business judgment.

          .    be  highly  accomplished  in his or her  respective  field,  with
               superior  credentials and recognition and broad experience at the
               administrative    and/or   policy-making   level   in   business,
               government, education, technology or public interest.

          .    have  relevant  expertise  and  experience,  and be able to offer
               advice  and  guidance  to the CEO  based  on that  expertise  and
               experience.

          .    be  independent  of  any  particular  constituency,  be  able  to
               represent  all  shareowners  of the Company and be  committed  to
               enhancing long-term shareowner value; and

          .    have  sufficient  time  available to devote to  activities of the
               Board of  Directors  and to enhance his or her  knowledge  of the
               Company's business.

The Committee also believes the following  qualities or skills are necessary for
one or more directors to possess:

          .    At least one director  should have the requisite  experience  and
               expertise  to be  designated  as an  "audit  committee  financial
               expert" as defined by the applicable rules of the SEC.

               organizations,  including commercial,  governmental,  educational

The Nominating and Governance  Committee will consider  nominees  recommended by
shareowners in accordance with the Company's Nominating and Governance Committee
Charter and the Corporate Governance Principles.

The Company and the Committee maintain a file of recommended  potential director
nominees  which is reviewed at the time a search for a new director  needs to be
performed.  To assist the Committee in its  identification of qualified director
candidates,  the Committee  may engage an outside  search firm.

Any shareowner  wishing to make a  recommendation  should write to the Corporate
Secretary  of the  Company  and  include  appropriate  biographical  information
concerning  each  proposed  nominee.  The Corporate  Secretary  will forward all
recommendations  to the Committee.  The Company's  Bylaws also set forth certain
requirements for shareowners  wishing to nominate director  candidates  directly
for consideration by shareowners.  These provisions  require such nominations to
be made pursuant to timely notice (as specified in the Bylaws) in writing to the
Corporate Secretary of the Company.

Capital Approval Committee
- ---------------------------

The Capital Approval Committee held no meetings in 2003. The Committee currently
consists of M. L. Bennett,  J. B. Evans and A. R. Weiler. Mr. Davis is the Chair
and a non-voting  member of this Committee.  The purpose of this Committee is to
evaluate certain investment  proposals where (1) an iterative bidding process is
required, and/or (2) the required timelines for such a proposal would not permit
the  proposal to be brought  before a regular  meeting of the Board of Directors
and/or a special  meeting of the full Board of  Directors  is not  practical  or
merited.

The Board of Directors held nine meetings during 2003. Each director attended at
least 75% of the aggregate  number of meetings of the Board and Board committees
on which he or she served.

The  Board  and each  committee  conduct  performance  evaluations  annually  to
determine their  effectiveness  and suggest  improvements for  consideration and
implementation.  In addition, the Compensation and Personnel Committee evaluates
Mr. Davis' performance as CEO on an annual basis.

Board  members  are  expected  to  attend  the  Company's   Annual   Meeting  of
Shareowners. All Board members, with the exception of Ms. Pyle, were present for
the Company's 2003 Annual Meeting of Shareowners.

                              CORPORATE GOVERNANCE


Corporate Governance Principles
- --------------------------------

The Board of Directors  has adopted  Corporate  Governance  Principles  that, in
conjunction  with  the  Board  committee   charters,   establish  processes  and
procedures to help ensure effective and responsive  governance by the Board. The
Corporate  Governance  Principles  are  available  on the  Company's  website at
www.alliantenergy.com/investors under the "Corporate Governance" caption.


The Board of Directors has adopted certain categorical standards of independence
to assist it in making  determinations of director  independence  under the NYSE
listing  standards.  These  categorical  standards  appear as  Appendix A of the
Corporate  Governance  Principles.  Based  on  these  standards,  the  Board  of
Directors has affirmatively  determined by resolution that each of the Company's
directors (other than Mr. Davis, the Company's Chairman and CEO) has no material
relationship with the Company and, therefore,  is independent in accordance with
the NYSE listing  standards.  The Board of Directors will  regularly  review the
continuing independence of the directors.

The Corporate Governance  Principles provide that at least 75% of the members of
the Board of  Directors  must be  independent  directors  under the NYSE listing
standards.  The Audit,  Nominating and Governance and Compensation and Personnel
Committees must consist of all independent directors.

Lead Independent Director; Executive Sessions
- ----------------------------------------------

The  Corporate  Governance  Principles  provide  that  the  chairperson  of  the
Nominating and Governance  Committee shall be the designated  "Lead  Independent
Director" or "Presiding  Independent  Director" and will preside as the chair at
meetings or executive sessions of the independent directors.  As the Chairperson
of the Nominating and Governance  Committee,  Mr. Weiler is currently designated
as the Lead  Independent  Director.  At every  regular  meeting  of the Board of
Directors, the independent directors meet in executive session with no member of
Company management present.


Communication with Directors
- -----------------------------

Shareowners and other  interested  parties may communicate  with the full Board,
non-management  directors  as a group or  individual  directors,  including  the
Presiding  Independent  Director,  by providing such communication in writing to
the Company's Corporate Secretary, who will post such communications directly to
the Company's Board of Directors' website.

Ethical and Legal Compliance Policy
- ------------------------------------

The  Company  has  adopted  a Code of  Ethics  that  applies  to all  employees,
including its CEO, Chief Operating  Officer,  Chief Financial  Officer and Chief
Accounting  Officer,  as well as its Board of  Directors.  The Company makes its
Code  of  Ethics  available  free  of  charge  on  the  Company's  website,   at
www.alliantenergy.com/investors,  under the "Corporate  Governance"  caption and
such Code of Ethics is available in print to any shareowner who requests it from
the Company's Corporate Secretary. The Company intends to satisfy the disclosure
requirements under Item 10 of Form 8-K regarding amendments to, or waivers from,
the Code of Ethics by posting such  information  on its website  address  stated
above under the Corporate Governance caption.

                   PROPOSAL FOR INCREASE IN AUTHORIZED SHARES

        PROPOSAL TO AMEND THE RESTATED ARTICLES OF INCORPORATION OF THE
              COMPANY TO INCREASE THE NUMBER OF AUTHORIZED SHARES


The Board of Directors recommends that shareowners vote FOR the proposal for the
amendment of the Company's  Restated  Articles of  Incorporation to increase the
number of authorized shares to 240,000,000 for the following reasons:

Currently, the Company's authorized capital stock under its Restated Articles of
Incorporation  is  200,000,000  shares  of  common  stock.  The  Company  is not
authorized   to  issue   preferred   stock  under  its   Restated   Articles  of
Incorporation.  As of April 1, 2004, of the 200,000,000  shares of the Company's
common  stock  presently  authorized,   _____________  shares  were  issued  and
outstanding, _____________ shares were reserved for issuance under the Company's
Shareowner Direct Plan,  ___________shares  were reserved for issuance under the
Company's  401(k) Plan,  ___________shares  were reserved for issuance under the
Company's  Long-Term  Incentive  Plan,  _____________  shares were  reserved for
issuance under the Company's 2002 Equity Incentive Plan and _____________ shares
were reserved for issuance under the Company's  Rights  Agreement.  As a result,
there are now only ____________  authorized shares of the Company's common stock
that are not reserved and that may be issued for any future business purposes by
the Company.

Accordingly, the Board of Directors has approved for submission to the Company's
shareowners, and recommends that the Company's shareowners approve, an amendment
to the Company's  Restated  Articles of  Incorporation to increase the number of
authorized shares of common stock from 200,000,000 to 240,000,000.

The additional 40,000,000 authorized shares of the Company's common stock may be
issued for any proper  corporate  purpose  approved  by the  Company's  Board of
Directors.  The  availability  of additional  authorized  shares will enable the
Company's Board of Directors to act with flexibility when and as the need arises
to issue  additional  shares in the future  without the delays  necessitated  by
having to obtain a shareowner  vote and to take advantage of changing market and
financial  conditions  in a more  timely  manner.  Among the reasons for issuing
additional  shares would be to increase the Company's  capital  through sales of
the Company's  common stock,  to engage in other types of capital  transactions,
and to satisfy contractual commitments.

The Company  anticipates  that it will require in the future a greater number of
authorized shares of common stock than is currently available under its Restated
Articles of Incorporation  to issue new equity to fund, among other things,  its
recently  announced  domestic  generation   build-out  program.   The  Company's
management  regularly  reviews  a  range  of  possible  financing  transactions,
including  the issuance of the  Company's  common  stock.  Subject to market and
other  conditions,  the Company intends to sell additional equity in 2004. These
equity sales may involve traditional  underwritten offerings,  continuous equity
offerings or other  transactions.  Such offerings will be made from a portion of
the __________ of existing  authorized shares of the Company's common stock that
are  currently  not reserved  and that may be issued for the purposes  described
above.

                                      -13-


If  the  amendment  to the  Company's  Restated  Articles  of  Incorporation  is
approved,  while the  Company's  Board of  Directors  generally  may issue  such
additional  authorized  shares of the  Company's  common stock  without  further
shareowner  approval,  such issuances will generally require the approval of the
Securities and Exchange  Commission under the Public Utility Holding Company Act
of 1935.

In some instances, shareowner approval for the issuance of additional shares may
be required by law or by the requirements of the New York Stock Exchange, or the
obtaining  of  such  approvals  may be  otherwise  necessary  or  desirable.  In
particular,  under the  listing  standards  of the New York Stock  Exchange,  an
increase in shares reserved for issuance under equity compensation plans for the
Company's employees or in a transaction  including the issue of more than 20% of
the outstanding shares would be subject to shareowner  approval.  In such cases,
further shareowner authorization will be solicited.

The Company's  Board of Directors has not proposed the increase in the amount of
authorized  shares with the intention of discouraging  tender offers or takeover
attempts of the Company.  However,  the  availability  of additional  authorized
shares for issuance could render more  difficult or discourage a merger,  tender
offer,  proxy contest or other attempt to obtain  control of the Company,  which
may  adversely  affect the  ability  of the  Company's  shareowners  to obtain a
premium for their shares of the Company's common stock.

To approve this proposal, the number of votes cast in favor of the proposal must
exceed the  number of votes cast in  opposition  to it.  Abstentions  and broker
non-votes will be counted for purposes of determining  the presence of a quorum,
as noted above,  but do not  constitute a vote "for" or "against" any matter and
will be disregarded in the calculations of "votes cast."

The Board of Directors unanimously recommends that shareowners vote FOR approval
of the proposal to amend the Company's  Restated  Articles of  Incorporation  to
increase the number of authorized shares to 240,000,000.

                           COMPENSATION OF DIRECTORS


No retainer fees are paid to Mr. Davis for his service on the Company's Board of
Directors. In 2003, all other directors (the "non-employee directors"),  each of
whom served on the Boards of the Company, IP&L, WP&L and AER, received an annual
retainer for service on all four Boards  consisting  of $47,137 in cash. Of this
cash amount, each Director  voluntarily elected to use $17,137 to purchase 1,000
shares of Company common stock pursuant to the Company's  Shareowner Direct Plan
or to defer such  amount  through the Company  Stock  account in the  Directors'
Deferred  Compensation  Plan.  Travel  expenses  are paid for each  meeting  day
attended.

In 2004,  the Board of Directors  will receive a cash  retainer of $70,000.  The
Directors are  encouraged to make a voluntary  election to use not less than 50%
of this cash retainer to purchase shares of the Company's  common stock pursuant
to the  Company's  Shareowner  Direct Plan or to defer through the Company Stock
account in the Directors'  Deferred  Compensation Plan. In 2004, the Chairperson
of the Audit  Committee will receive an additional  $7,500 cash retainer and the
Chairpersons of the Nominating and Governance,  Compensation and Personnel,  and
Environmental, Nuclear, Health, and Safety Committees will receive an additional
$5,000 cash retainer.

Director's Deferred Compensation Plan
- --------------------------------------

Under the Director's  Deferred  Compensation Plan,  directors may elect to defer
all or part of their retainer fee. Amounts deposited to a Deferred  Compensation
Interest  Account receive an annual return based on the A-Utility Bond Rate with
a minimum  return no less than the prime  interest  rate  published  in The Wall
Street  Journal,  provided  that the return may not be greater  than 12% or less
than 6%.  Amounts  deposited  to a Company  Stock  Account are treated as though
invested in the common stock of the Company and will be credited with dividends,
which will be treated as if reinvested. The director may elect that the Deferred
Compensation  Account be paid in a lump sum or in annual  installments for up to
10  years  beginning  in the  year  of or  one  tax  year  after  retirement  or
resignation from the Board.

Director's Charitable Award Program
- ------------------------------------

The Company  maintains a Director's  Charitable Award Program for the members of
its Board of Directors  beginning  after three years of service.  The purpose of
the Program is to  recognize  the  interest of the Company and its  directors in
supporting  worthy  institutions  and to enhance the Company's  director benefit
program so that the Company is able to continue to attract and retain  directors
of the highest  caliber.  Under the Program,  when a director  dies, the Company
will donate a total of  $500,000 to one  qualified  charitable  organization  or
divide that amount among a maximum of five  qualified  charitable  organizations
selected  by  the  individual  director.  The  individual  director  derives  no
financial benefit from the Program. All deductions for charitable  contributions
are taken by the Company,  and the donations  are funded by the Company  through
life  insurance  policies on the  directors.  Over the life of the Program,  all
costs of donations  and  premiums on the life  insurance  policies,  including a
return of the Company's cost of funds,  will be recovered through life insurance
proceeds on the directors.  The Program,  over its life,  will not result in any
material cost to the Company.

                                      -15-


Director's Life Insurance Program
- -----------------------------------

The Company  maintains a  split-dollar  Director's  Life  Insurance  Program for
non-employee directors, beginning after three years of service, which provides a
maximum  death  benefit  of  $500,000  to  each  eligible  director.  Under  the
split-dollar arrangement, directors are provided a death benefit only and do not
have any interest in the cash value of the policies.  The Life Insurance Program
is  structured  to pay a portion of the total  death  benefit to the  Company to
reimburse  the Company for all costs of the  program,  including a return on its
funds.  The Life  Insurance  Program,  over its  life,  will not  result  in any
material cost to the Company.  The imputed income allocations  reported for each
director in 2003 under the Director's Life Insurance Program were as follows: A.
B. Arends - $50,  J. B. Evans - $2, K. C. Lyall - $488,  J. D. Pyle - $24, W. H.
Stoppelmoor - $987 and A. R. Weiler - $50.

In November 2003, the Board of Directors  terminated this insurance  benefit for
any director not already  having the required  vesting  period of three years of
service and for all new directors.

employment  agreement is $685,000.  Mr. Davis also has the  opportunity  to earn
short-term  and  long-term  incentive  compensation  (including  stock  options,
restricted  stock  and  other  long-term  incentive  compensation)  and  receive
supplemental  retirement benefits (including continued participation in the WP&L
Executive Tenure Compensation Plan) and life insurance providing a death benefit
of three times his annual  salary.  If the employment of Mr. Davis is terminated
without  cause  (as  defined  in  the  employment  agreement)  or if  Mr.  Davis
terminates  his  employment  for  good  reason  (as  defined  in the  employment
agreement),  the  Company  or  its  affiliates  will  continue  to  provide  the
compensation and benefits called for by the employment agreement through the end
of the term of such employment  agreement (with incentive  compensation based on
the maximum potential awards and with any stock  compensation paid in cash), and
all unvested  stock  compensation  will vest  immediately.  If Mr. Davis dies or
becomes disabled,  or terminates his employment without good reason,  during the
term of his respective employment agreement,  the Company or its affiliates will
pay to Mr. Davis or his beneficiaries or estate all compensation  earned through
the date of death, disability or such termination (including previously deferred
compensation  and  pro  rata  incentive  compensation  based  upon  the  maximum
potential  awards).  If Mr. Davis is  terminated  for cause,  the Company or its
affiliates  will pay his base salary  through the date of  termination  plus any
previously deferred compensation.  Under Mr. Davis' employment agreement, if any
payments  thereunder  constitute an excess parachute  payment under the Internal
Revenue  Code  (the  "Code"),  the  Company  will pay to Mr.  Davis  the  amount
necessary to offset the excise tax and any applicable  taxes on this  additional
payment.

The Company  currently  has in effect key  executive  employment  and  severance
agreements (the "KEESAs") with certain  executive  officers and key employees of
the Company  (including  Messrs.  Davis,  Harvey,  Hoffman,  and Protsch and Ms.
Wegner).  The KEESAs provide that each executive  officer who is a party thereto
is entitled to benefits if,  within a period of up to three years  (depending on
which  executive  is  involved)  after a change in  control of the  Company  (as
defined in the KEESAs) (the "Employment  Period"),  the officer's  employment is
ended through (a)  termination by the Company,  other than by reason of death or
disability or for cause (as defined in the KEESAs);  or (b)  termination  by the
officer due to a breach of the agreement by the Company or a significant  change
in the officer's  responsibilities;  or (c) in the case of Mr. Davis' agreement,
termination  by Mr.  Davis  following  the first  anniversary  of the  change of
control. The benefits provided are (a) a cash termination payment of up to three
times (depending on which executive is involved) the sum of the officer's annual
salary and his or her average  annual  bonus  during the three years  before the
termination;  and (b) continuation for up to the end of the Employment Period of
equivalent hospital, medical, dental, accident and life insurance coverage as in
effect at the time of termination.  Each KEESA for executive  officers below the
level of Executive Vice  President  provides that if any portion of the benefits
under the KEESA or under any other agreement for the officer would constitute an
excess parachute  payment for purposes of the Code,  benefits will be reduced so
that the officer  will be  entitled  to receive $1 less than the maximum  amount
which he or she could  receive  without  becoming  subject to the 20% excise tax
imposed by the Code on certain excess parachute  payments,  or which the Company
may pay  without  loss of  deduction  under the Code.  The  KEESAs for the Chief
Executive Officer,  President, Senior Executive Vice President and the Executive
Vice Presidents  (including  Messrs.  Davis,  Harvey,  Hoffman,  and Protsch and
Ms.Wegner)  provide that if any payments  thereunder or otherwise  constitute an
excess parachute  payment,  the Company will pay to the appropriate  officer the
amount  necessary  to offset  the excise  tax and any  additional  taxes on this
additional  payment.  Mr. Davis' employment  agreement as described above limits
benefits paid thereunder to the extent that duplicate payments would be provided
to him under his KEESA.

The Company  entered into a Severance  Agreement  and Release with Mr. Walker in
connection with the conclusion of his employment with the Company as of November
15, 2003. The Company (a) paid Mr. Walker $680,000, (b) paid $10,000 towards his
legal fees  associated  with the agreement and (c) agreed to provide him with up
to $20,000 for either outplacement services or tuition reimbursement. Mr. Walker
ceased to be eligible to  participate  under any of the Company's  stock option,
bonus, equity,  incentive  compensation,  non-qualified  supplemental retirement
plan,   medical,   dental,  life  insurance,   retirement,   pension  and  other
compensation or benefit plans upon his termination of employment, except that he
retained vested rights under the Company's  qualified  retirement  plans and his
rights under the Company's Key Employee  Deferred  Compensation  Plan, and he is
eligible for COBRA  continuation for his medical and dental plans. If Mr. Walker
elects COBRA  continuation,  the Company will pay for this coverage for up to 18
months.  Under the  agreement,  Mr. Walker agreed to a two-year  covenant not to
compete and agreed to keep Company information confidential.  In connection with
the agreement, Mr. Walker provided the Company a general liability release.

                     RETIREMENT AND EMPLOYEE BENEFIT PLANS

Alliant Energy Cash Balance Pension Plan

Salaried  employees   (including  officers)  of  the  Company  are  eligible  to
participate in the Alliant Energy Cash Balance Pension Plan (the "Pension Plan")
maintained  by Alliant  Energy  Corporate  Services.  The  Pension  Plan bases a
participant's  defined  benefit  pension on the value of a hypothetical  account
balance. For individuals participating in the Pension Plan as of Aug. 1, 1998, a
starting  account  balance was created equal to the present value of the benefit
accrued as of Dec. 31, 1997,  under the  applicable  prior benefit  formula.  In
addition,  such individuals received a special one-time transition credit amount
equal to a specified  percentage varying with age multiplied by credited service
and pay. For 1998 and thereafter,  a participant  receives annual credits to the
account equal to 5% of base pay (including certain incentive  payments,  pre-tax
deferrals and other items),  plus an interest credit on all prior accruals equal
to 4%, plus a potential share of the gain on the investment  return on assets in
the trust investment for the year.

The life annuity  payable under the Pension Plan is determined by converting the
hypothetical  account  balance  credits into annuity form.  Individuals who were
participants in the Pension Plan on Aug. 1, 1998, are in no event to receive any
less than  what  would  have been  provided  under  the prior  formula  that was
applicable  to them,  had it continued,  if they  terminate on or before Aug. 1,
2008, and do not elect to commence benefits before the age of 55.

All of the individuals  listed in the Summary  Compensation Table participate in
the Plan  and are  "grandfathered"  under  the  applicable  prior  plan  benefit
formula.  Because  their  estimated  benefits  under the  applicable  prior plan
benefit  formula  are higher  than under the  Pension  Plan  formula,  utilizing
current  assumptions,  their  benefits  would  currently  be  determined  by the
applicable  prior plan benefit  formula.  The following  tables  illustrate  the
estimated annual benefits payable upon retirement at age 65 under the applicable
prior plan formula based on average annual compensation and years of service. To
the extent  benefits  under the Plan are limited by tax law,  any excess will be
paid under the Unfunded Excess Plan described below.

                                      -25-


WP&L Plan A Prior Formula.  One of the applicable  prior plan formulas  provided
retirement  income  based  on  years  of  credited  service  and  final  average
compensation for the 36 highest  consecutive months, with a reduction for Social
Security  offset.  The  individuals  listed in the  Summary  Compensation  Table
covered by this formula are Messrs. Davis,  Protsch and Harvey and Ms. Wegner.
The benefits would be as follows:

For  purposes of the  Pension  Plan,  compensation  means  payment for  services
rendered,  including  vacation and sick pay, and is substantially  equivalent to
the salary  amounts  reported in the Summary  Compensation  Table.  Pension Plan
benefits  depend  upon  length of Pension  Plan  service  (up to a maximum of 30
years),  age at retirement and amount of compensation  (determined in accordance
with the Pension Plan) and are reduced by up to 50% of Social Security benefits.
The  estimated  benefits in the table  above do not reflect the Social  Security
offset.  The estimated  benefits are computed on a straight-life  annuity basis.
Benefits will be adjusted if the employee  receives one of the optional forms of
payment.  Credited  years of service under the Pension Plan for covered  persons
named in the Summary Compensation Table are as follows: Erroll B. Davis, Jr., 24
years;  Eliot G. Protsch,  24 years;  William D. Harvey, 16 years; and Pamela J.
Wegner, 9 years.

                                      -26-


IES Industries Pension Plan Prior Formula.  Another of the applicable prior plan
formulas provided  retirement income based on years of service and final average
compensation  for the highest  consecutive 36 months out of the last 10 years of
employment.   Mr.  Hoffman  is  the  only  individual   listed  in  the  Summary
Compensation Table covered by this formula. The benefits would be as follows:

For  purposes of the  Pension  Plan,  compensation  means  payment for  services
rendered,  including  vacation and sick pay, and is substantially  equivalent to
the salary  amounts  reported in the Summary  Compensation  Table.  Pension Plan
benefits  depend  upon  length of Pension  Plan  service  (up to a maximum of 35
years),  age at retirement and amount of compensation  (determined in accordance
with the Pension Plan).  The estimated  benefits are computed on a straight-life
annuity  basis.  Benefits  will be adjusted if the employee  receives one of the
optional forms of payment. Mr. Hoffman has eight credited years of service under
the Pension  Plan. At the time of his  resignation  from the Company in November
2003, Mr. Walker had a vested balance of $68,056 in the Pension Plan.

                                      -27-


Unfunded Excess Plan

Alliant  Energy  Corporate  Services  maintains  an  Unfunded  Excess  Plan that
provides  funds for payment of  retirement  benefits  above the  limitations  on
payments  from  qualified  pension  plans in  those  cases  where an  employee's
retirement  benefits exceed the qualified plan limits.  The Unfunded Excess Plan
provides an amount equal to the difference  between the actual  pension  benefit
payable  under  the  Pension  Plan and what  such  pension  benefit  would be if
calculated  without  regard to any  limitation  imposed  by the Code on  pension
benefits or covered compensation.

Unfunded Executive Tenure Compensation Plan

Alliant  Energy  Corporate  Services  maintains  an  Unfunded  Executive  Tenure
Compensation  Plan to provide incentive for selected key executives to remain in
the service of the Company by providing additional  compensation that is payable
only if the  executive  remains  with the  Company  until  retirement  (or other
termination  if  approved by the Board of  Directors).  In the case of the Chief
Executive  Officer  only, in the event that the Chief  Executive  Officer (a) is
terminated  under his employment  agreement with the Company as described  above
other than for cause,  death or  disability  (as those  terms are defined in the
employment  agreement);  (b)  terminates  his  employment  under the  employment
agreement for good reason (as such term is defined in the employment agreement);
or (c) is terminated as a result of a failure of the employment  agreement to be
renewed  automatically  pursuant to its terms (regardless of the reason for such
non-renewal),  then for purposes of the Plan, the Chief Executive  Officer shall
be deemed to have retired at age 65 and shall be entitled to benefits  under the
Plan.  Any  participant  in the Plan must be approved by the Board of Directors.
Mr. Davis was the only active  participant in the Plan as of Dec. 31,  2003. The
Plan provides for monthly  payments to a  participant  after  retirement  (at or
after age 65,  or with  Board  approval,  prior to age 65) for 120  months.  The
payments will be equal to 25% of the  participant's  highest  average salary for
any consecutive  36-month  period.  If a participant dies prior to retirement or
before 120 payments have been made, the  participant's  beneficiary will receive
monthly payments equal to 50% of such amount for 120 months in the case of death
before  retirement or, if the  participant  dies after  retirement,  50% of such
amount for the balance of the 120 months.  Annual  benefits of $171,250 would be
payable to Mr. Davis upon  retirement,  assuming he continues in Alliant  Energy
Corporate Services' service until retirement at the same salary as was in effect
on Dec. 31, 2003.

Supplemental Executive Retirement
Plan

The  Company  maintains  an  unfunded  Supplemental  Executive  Retirement  Plan
("SERP") to provide incentive for key executives to remain in the service of the
Company  by  providing  additional  compensation  that  is  payable  only if the
executive remains with the Company until retirement,  disability or death. While
the SERP  provides  different  levels of  benefits  depending  on the  executive
covered,  this summary  reflects the terms  applicable to all of the individuals
listed  in the  Summary  Compensation  Table.  Participants  in the SERP must be
approved by the  Compensation  and  Personnel  Committee of the Board.  The SERP
provides for payments of 60% of the participant's  average annual earnings (base
salary and bonus) for the  highest  paid three years out of the last 10 years of
the  participant's  employment  reduced  by the sum of  benefits  payable to the
officer from the officer's  defined  benefit plan and the Unfunded  Excess Plan.
The  normal  retirement  date under the SERP is age 62 with at least 10 years of
service and early retirement is at age 55 with at least ten years of service. If
a participant retires prior to age 62, the 60% payment under the SERP is reduced
by 3% per year for each year the participant's  retirement date precedes his/her
normal  retirement  date.  The  actuarial  reduction  factor  will be waived for
participants  who have attained age 55 and have a minimum of 10 years of service
in a senior  executive  position  with the Company  after April 21, 1998. At the
timely  election of the  participant,  benefits under the SERP will be made in a
lump sum, in  installments  over a period of up to 10 years, or for the lifetime
of the participant. If the lifetime benefit is selected and the participant dies
prior to  receiving  12 years of payments,  payments  continue to any  surviving
spouse or  dependent  children  of a deceased  participant  who dies while still
employed by the Company,  payable for a maximum of 12 years.  A  post-retirement
death benefit of one times the participant's  final average earnings at the time
of retirement will be paid to the designated beneficiary. Messrs. Davis, Harvey,
Hoffman,  and Protsch and Ms. Wegner are participants in the SERP. The following
table shows the amount of retirement payments under the SERP, assuming a minimum
of 10 years of service at retirement age and payment in the annuity form.

Key Employee Deferred Compensation Plan

The Company maintains an unfunded Key Employee Deferred  Compensation Plan under
which participants may defer up to 100% of base salary,  incentive  compensation
and  eligible  SERP  payments.  Participants  who have made the maximum  allowed
contribution  to the  Company-sponsored  401(k) Plan may  receive an  additional
credit to the Deferred Compensation Plan. The credit will be equal to 50% of the
lesser of (a) the amount contributed to the 401(k) Plan plus the amount deferred
under this Plan; or (b) 6% of base salary, reduced by the amount of any matching
contributions  in the 401(k)  Plan.  The  employee  may elect to have his or her
deferrals credited to an Interest Account or a Company Stock Account.  Deferrals
and matching  contributions  to the Interest  Account  receive an annual  return
based on the  A-Utility  Bond Rate with a minimum  return no less than the prime
interest rate published in The Wall Street Journal, provided that the return may
not be greater than 12% or less than 6%.  Deferrals  and matching  contributions
credited to the  Company  Stock  Account  are treated as though  invested in the
common stock of the Company and will be credited with  dividends,  which will be
treated as if reinvested.  The shares of common stock  identified as obligations
under the Plan are held in a rabbi trust.  Payments from the Plan may be made in
a lump sum or in annual  installments  for up to 10 years at the election of the
participant. Participants are selected by the Chief Executive Officer of Alliant
Energy Corporate Services.  Messrs.  Davis, Harvey,  Hoffman and Protsch and Ms.
Wegner are participants in the Plan.

                    REPORT OF THE COMPENSATION AND PERSONNEL
                      COMMITTEE ON EXECUTIVE COMPENSATION


To Our Shareowners:

The  Compensation  and Personnel  Committee  (the  "Committee")  of the Board of
Directors of the Company is currently  comprised of five independent  directors.
The Committee  assesses the effectiveness and  competitiveness  of, approves the
design of and administers  executive  compensation  programs within a consistent
total  compensation  framework for the Company.  The Committee  also reviews and
approves  all  salary   arrangements  and  other  remuneration  for  executives,
evaluates  executive  performance,  and considers related matters. It also makes
recommendations  to the Nominating and Governance  Committee  regarding Director
compensation.  To support it in carrying out its mission,  the Committee engages
an independent consultant to provide assistance.

The Committee is committed to implementing an overall  compensation  program for
executives that furthers the Company's mission. Therefore, the Committee adheres
to the following  compensation  policies,  which are intended to facilitate  the
achievement of the Company's business strategies:

          *    Executive  management  compensation (and particularly,  long-term
               incentive  compensation)  should be closely and strongly  aligned
               with the long-term interests of the Company's shareowners.

          *    Total  compensation  should  enhance  the  Company's  ability  to
               attract,  retain and encourage the  development of  exceptionally
               knowledgeable  and  experienced  executives,  upon whom, in large
               part,  the  successful  operation  and  management of the Company
               depends.


          *    Base salary  levels  should be targeted at a  competitive  market
               range  of  base   salaries   paid  to  executives  of  comparable
               companies.  Specifically, the Committee targets the median (50th)
               percentile of base salaries paid by companies  within the utility
               and general industries.

          *    Incentive    compensation    programs   should   strengthen   the
               relationship between pay and performance by emphasizing variable,
               at-risk    compensation   that   is   consistent   with   meeting
               predetermined Company,  subsidiary,  business unit and individual
               performance  goals. In addition,  the Committee targets incentive
               levels at the median (50th percentile) of incentive  compensation
               paid by similarly sized companies  within the utility and general
               industries.

The major  elements of the  Company's  executive  compensation  program are base
salary, short-term (annual) incentives and long-term (equity) incentives.  These
elements are  addressed  separately  below.  In setting the level for each major
component  of  compensation,   the  Committee   considers  all  elements  of  an
executive's  total   compensation   package,   including  employee  benefit  and
perquisite programs.  The Committee's goal is to provide an overall compensation
package for each executive  officer that is competitive to the packages  offered
other  similarly  situated  executives.  The Committee has determined that total
executive  compensation  at target levels,  including that for Mr. Davis,  is in
line with competitive compensation of comparative companies.

Base Salaries

The Committee  annually reviews each executive's base salary.  Base salaries are
targeted  at a  competitive  market  range  (i.e.,  at the  median  level)  when
comparing both utility and  non-utility  (general  industry) data. The Committee
annually  adjusts  base  salaries to  recognize  changes in the market,  varying
levels of responsibility,  prior experience and breadth of knowledge.  Increases
to base  salaries are driven  primarily by market  adjustments  for a particular
salary level, which generally limits across-the-board  increases.  The Committee
considers individual performance factors in setting base salaries. The Committee
reviewed executive salaries for market  comparability  using utility and general
industry data contained in compensation surveys published by The Edison Electric
Institute,  The American Gas  Association  and several  compensation  consulting
firms.

In consideration of industry conditions and Company  performance,  the Committee
did not  increase  the base  salaries  of the Chief  Executive  Officer  and the
Executive Vice Presidents in 2003.

Short-Term Incentives

The Company's  short-term  (annual)  incentive  program promotes the Committee's
pay-for-performance  philosophy by providing  executives  with direct  financial
incentives  in the  form of  annual  cash  bonuses  tied to the  achievement  of
Company,  subsidiary,  business unit and individual  performance  goals.  Annual
bonus opportunities  allow the Committee to communicate  specific goals that are
of primary importance during the coming year and motivate  executives to achieve
these goals. The Committee on an annual basis reviews and approves the program's
performance  goals,  the relative  weight assigned to each goal and the targeted
and maximum award levels.  A description  of the short-term  incentive  programs
available during 2002 to executive officers follows.

                                      -31-


Alliant Energy Corporation Management Incentive Compensation Plan - In 2003, the
Alliant Energy Corporation  Management Incentive  Compensation Plan (the "MICP")
covered  executives  and was  based  on  achieving  annual  targets  in  Company
performance  that  included  earnings  per share  ("EPS"),  cash  flow,  safety,
diversity and  environmental  targets for the utility  businesses,  and business
unit (including  customer service and  reliability)  and individual  performance
goals.  Target and maximum  bonus  awards under the MICP in 2003 were set at the
median  of the  utility  and  general  industry  market  levels.  The  Committee
considered  these  targets  to  be  achievable,  but  to  require  above-average
performance  from each of the executives.  The level of performance  achieved in
each category  determines  actual payment of bonuses,  as a percentage of annual
salary.  Weighting factors are applied to the percentage  achievement under each
category to determine overall performance. If a pre-determined EPS target is not
met,  there is no bonus  payment  associated  with the  MICP.  If the  threshold
performance for any other performance  target is not reached,  there is no bonus
payment  associated with that particular  category.  Once the designated maximum
performance is reached, there is no additional payment for performance above the
maximum  level.  The actual  percentage  of salary  paid as a bonus,  within the
allowable  range, is equal to the weighted  average percent  achievement for all
the  performance  categories.  Potential  MICP  awards  range from 0% to 100% of
annual salary for eligible executives.

Due to industry and market conditions,  the Committee  determined that the Chief
Executive  Officer and Executive  Vice  Presidents  were not eligible to receive
MICP awards for 2003 plan year performance.

Long-Term Incentives

The Committee  strongly  believes  compensation  for  executives  should include
long-term,  at-risk pay to  strengthen  the  alignment  of the  interests of the
shareowners and  management.  In this regard,  the Company  maintains plans that
permit grants of stock options,  restricted  stock and performance  units/shares
with respect to the  Company's  common stock.  The  Committee  believes that the
incentive  plans  balance  the  Company's   annual   compensation   programs  by
emphasizing  compensation based on the long-term,  successful performance of the
Company from the perspective of the Company's shareowners.  A description of the
long-term  incentive programs available during 2003 to executive officers is set
forth below.

Alliant  Energy  Corporation  Long-Term  Incentive  Program - The Alliant Energy
Corporation  Long-Term Incentive Program covered executives and consisted of the
following  components  in 2003:  non-qualified  stock  options  and  performance
shares.  Non-qualified  stock options  provide a reward that is directly tied to
the benefit  shareowners  receive from  increases in the price of the  Company's
common stock.  Until 2003, the payout from the  performance  shares was based on
two  equally-weighted  performance  components:  the Company's  three-year total
return to shareowners  relative to an  investor-owned  utility peer group (TSR),
and annualized EPS growth versus internally set performance hurdles contained in
the  Alliant  Energy  Strategic  Plan.   Beginning  in  2003,  total  return  to
shareowners  was used as the sole measure of the performance  share plan.  Thus,
the two components of the Long-Term  Incentive Program (i.e.,  stock options and
performance  shares)  provide  incentives  for  management  to produce  superior
shareowner  returns on both an absolute and  relative  basis.  During 2003,  the
Committee  made a grant of stock  options  and  performance  shares  to  various
executive officers, including Messrs. Davis, Harvey, Hoffman and Protsch and Ms.
Wegner. All option grants had per share exercise prices equal to the fair market
value of a share of  Company  common  stock  on the day  following  the date the
grants were approved. Options vest on a one-third basis at the beginning of each
calendar  year after  grant and have a 10-year  term from the date of the grant.
Such executives were also granted performance shares. Performance shares will be
paid out in a combination  of common stock and cash.  The award will be modified
by a  performance  multiplier,  which  ranges  from 0 to 2.00  based on  Company
performance.

                                      -32-


In  determining  actual  award  levels  under  the  Alliant  Energy  Corporation
Long-Term  Incentive  Program,   the  Committee  was  primarily  concerned  with
providing a competitive total  compensation  opportunity  level to officers.  As
such,  award  levels  (including  awards  made to Mr.  Davis)  were  based  on a
competitive  analysis of similarly sized utility and general industry  companies
that took into consideration the market level of long-term  incentives,  as well
as the  competitiveness  of the total compensation  package.  The Committee then
established  award ranges and  individual  award levels based on  responsibility
level  and  market  competitiveness.  No  corporate  or  individual  performance
measures were reviewed in connection  with the awards of options and performance
shares.  Award  levels  were  targeted to the median of the range of such awards
paid by  comparable  companies.  The  Committee  did not consider the amounts of
options and performance  shares already  outstanding or previously  granted when
making awards for 2003. Mr. Davis' awards in 2003 under the Long-Term  Incentive
Program  are  shown in the  tables  under  "Stock  Option  Grants  in 2003"  and
"Long-Term Incentive Awards in 2003."

Due to the EPS and TSR  goals not being  achieved,  there was no payout  for the
performance share portion of the Long-Term Incentive Program's  three-year cycle
that ended in December 2003.

Share Ownership Guidelines

The Company has established share ownership guidelines for executive officers as
a way to better align the financial  interests of its officers with those of its
shareowners.  These  officers are expected to make  continuing  progress  toward
compliance  with  these  guidelines.   Under  these  guidelines,  the  requisite
ownership  numbers are 85,000  shares for the Chief  Executive  Officer,  36,000
shares for Executive  Vice  Presidents,  and 12,000 shares for Vice  Presidents.
Attainment of these ownership levels is reviewed regularly by the Committee. The
Chief  Executive  Officer  retains the right to grant special  dispensation  for
hardship, promotions or new hires.

Policy with Respect to the $1 Million Deduction Limit

Section  162(m)  of the  Code  generally  limits  the  corporate  deduction  for
compensation  paid to  executive  officers  named in the proxy  statement  to $1
million unless such  compensation is based upon performance  objectives  meeting
certain regulatory criteria or is otherwise excluded from the limitation.  Based
on the Committee's commitment to link compensation with performance as described
in this report, the Committee intends to qualify future compensation paid to the
Company's  executive  officers for  deductibility  by the Company  under Section
162(m) except in limited appropriate circumstances.

Conclusion

The Committee believes the existing executive compensation policies and programs
provide an  appropriate  level of  competitive  compensation  for the  Company's
executives.  In addition,  the Committee  believes that the long- and short-term
performance  incentives  effectively  align  the  interests  of  executives  and
shareowners toward a successful future for the Company.

                         REPORT OF THE AUDIT COMMITTEE

To Our Shareowners:

The Audit Committee of the Board of Directors of the Company is composed of five
directors,  each of whom is independent under the NYSE listing standards and SEC
rules.  The Committee  operates under a written  charter adopted by the Board of
Directors.  The Audit Committee  charter as amended by the Board of Directors on
March 11, 2004, is attached as Appendix A to this proxy statement.

The Company's  management is responsible for the Company's internal controls and
the financial reporting process,  including the system of internal controls. The
independent auditors are responsible for expressing an opinion on the conformity
of the Company's  audited  consolidated  financial  statements  with  accounting
principles generally accepted in the United States of America. The Committee has
reviewed  and  discussed  the audited  consolidated  financial  statements  with
management and the  independent  auditors.  The Committee has discussed with the
independent  auditors  matters required to be discussed by Statement on Auditing
Standards No. 61 (Communication With Audit Committees).

The  Company's  independent  auditors have provided to the Committee the written
disclosures   required  by   Independence   Standards   Board   Standard  No.  1
(Independence  Discussions with Audit Committees),  and the Committee  discussed
with the independent auditors their independence.

The Committee has adopted a policy that requires  advance approval of all audit,
audit-related,  tax and other  permitted  services  performed by the independent
auditor.  The policy provides for  pre-approval by the Committee of specifically
defined  audit and non-audit  services  after the Committee is provided with the
appropriate level of details regarding the specific services to be provided. The
policy does not permit delegation of the Committee's authority to management. In
the event the need for specific services arises between Committee meetings,  the
Committee has delegated to the Chairperson of the Committee authority to approve
permitted  services  provided that the Chairperson  reports any decisions to the
Committee at its next scheduled meeting.

The fees the Company paid to its independent  auditors for 2002 and 2003 were as
follows:

                           2002                 2003
                       -------------        -------------
Audit Fees              $2,843,000*          $2,293,000
Audit-Related Fees          19,000              332,000
Tax Fees                 1,125,000              435,000
All Other Fees             297,000               54,000


                                      -34-


Audit-Related Fees

consisted  of the fees billed for  Sarbanes-Oxley  Section 404 planning in 2003,
employee  benefits  plan  audits,  and attest  services  required  by statute or
regulations.


Tax Fees
- --------
consisted of the fees billed for professional services rendered for tax
compliance, tax advice and tax planning, including all services performed by the
professional staff in the independent auditors' tax division, except those
rendered in connection with the audit.


All  Other  Fees
- ----------------
consisted of license fees for tax and accounting research software products and,
in 2002, fees for generation strategy consultation.

___________________________________________________

*Includes approximately $1.4 million for 2000 and 2001 re-audit fees

The Audit Committee does not consider the provision of non-audit services by the
independent auditors described above to be incompatible with maintaining auditor
independence.

The Committee discussed with the Company's internal and independent auditors the
overall scopes and plans for their respective  audits.  The Committee meets with
the internal and independent  auditors,  with and without management present, to
discuss the  results of their  examinations,  the  evaluation  of the  Company's
internal controls and overall quality of the Company's financial reporting.

Based on the Committee's  reviews and discussions with management,  the internal
auditors  and  the  independent   auditors  referred  to  above,  the  Committee
recommended  to the Board of Directors that the audited  consolidated  financial
statements be included in the Company's  Annual Report on Form 10-K for the year
ended Dec. 31, 2003, for filing with the SEC.

                 COMPARISON OF FIVE-YEAR CUMULATIVE TOTAL RETURN

The SEC rules require that the Company show a graphical  comparison of the total
return on its common stock for the last five fiscal years with the total returns
of a broad market  index and a more  narrowly  focused  industry or group index.
(Total return is defined as the return on common stock  including  dividends and
stock price appreciation,  assuming  reinvestment of dividends.) The Company has
selected  the  Standard & Poor's  (S&P) 500 Index for the broad market index and
the S&P 500 Utilities Index as the industry  index.  These indices were selected
because  of their  broad  availability  and  recognition.  The  following  chart
compares the total return of an  investment  of $100 in Company  common stock on
Dec. 31, 1998, with like returns for the S&P 500 and S&P 500 Utilities  indices.
Pursuant to SEC rules, the table reflects only information  regarding the common
stock of the Company.

            SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE


Section  16(a) of the  Securities  Exchange Act of 1934  requires the  Company's
directors  and certain  officers  to file  reports of  ownership  and changes in
ownership of the Company's common stock and subsidiary  preferred stock with the
SEC and the NYSE.  As a matter of practice,  the Company's  Shareowner  Services
Department assists the Company's  reporting persons in preparing initial reports
of  ownership  and reports of changes in  ownership  and files those  reports on
their  behalf.  The Company is required to disclose in this proxy  statement the
failure  of  reporting  persons  to file these  reports  when due.  Based on the
written  representations  of the reporting  persons and on copies of the reports
filed with the SEC,  the  Company  believes  that all  reporting  persons of the
Company satisfied these filing requirements.







                                By Order of the Board of Directors,

APPENDIX A - AUDIT COMMITTEE CHARTER

Purposes and Role of Committee

The purposes of the Audit Committee (the  "Committee") of the Board of Directors
(the "Board") of Alliant Energy  Corporation  (the "Company") are to: (1) assist
Board oversight of (a) the integrity of the Company's financial statements,  (b)
the  Company's  compliance  with  legal  and  regulatory  requirements,  (c) the
independent auditors'  qualifications and independence,  and (d) the performance
of the Company's  internal  audit  function and  independent  auditors;  and (2)
prepare the report that Securities and Exchange Commission  ("Commission") rules
require to be  included  in the  Company's  annual  proxy  statement.  While the
Committee has the  responsibilities  and powers set forth in this Charter, it is
not the duty of the Committee to conduct  audits or determine that the Company's
financial  statements  and  disclosures  are  complete  and  accurate and are in
accordance with accounting principles generally accepted in the United States of
America ("GAAP") and applicable laws and regulations.


Committee Membership

The Committee shall consist of three or more members of the Board,  each of whom
satisfies  the  requirements  for  independence  and  experience  under  Section
10A(m)(3)  of  the  Securities  Exchange  Act  of  1934  (the  "Exchange  Act"),
Commission  rules and the listing  standards of the New York Stock Exchange (the
"NYSE").  The Board will endeavor to ensure that at least one  Committee  member
shall qualify as an "audit committee  financial expert" as defined by SEC rules.
Committee  members  may not  serve on audit  committees  of more  than two other
public  companies  without the prior consent of the Board to enable the Board to
determine  that such  service  would not impair the  ability of such a member to
effectively serve on the Audit Committee.


Appointment and Removal of Committee Members

The Committee  members shall be appointed by the Board  annually or as necessary
to fill vacancies upon recommendation of the Company's Nominating and Governance
Committee.  Each member  shall serve until his or her  successor is duly elected
and qualified or until such member's earlier resignation or removal.  Any member
of the Committee may be removed,  with or without  cause,  by a majority vote of
the  Board  upon  recommendation  of the  Company's  Nominating  and  Governance
Committee.


Committee Structure and Operations

The  Board  shall  designate  one  member of the  Committee  as its  Chair.  The
Committee  shall meet in formal  session at least  three times each year and, in
addition,  hold quarterly meetings with the independent  auditors and management
to discuss the annual audited financial  statements and the quarterly  financial
statements and earnings releases.  Additional meetings shall be held when deemed
necessary or desirable at the request of the Chairperson of the Board, the Chief
Executive Officer or any Committee member.  The Committee will meet periodically
in executive session without management present.

                                      -39-


Committee Responsibilities

The responsibilities of the Committee are to:

          1.   Be  directly  responsible  for  the  appointment,   compensation,
               retention, termination and oversight of the Company's independent
               auditors   (including   resolution   of   disagreements   between
               management  and  the  independent  auditors  regarding  financial
               reporting)  for the  purpose  of  preparing  or  issuing an audit
               report or related  work.  The  independent  auditors  must report
               directly to the Committee.

          2.   Pre-approve all audit services and permitted  non-audit  services
               to be performed by the  independent  auditors,  subject to the de
               minimus  exceptions for non-audit  services  described in Section
               10A(i)(1)(B)  of  the  Exchange  Act  that  are  approved  by the
               Committee prior to the completion of the audit. Such pre-approval
               may  be  pursuant  to   pre-approval   policies  and   procedures
               established   by  the   Committee   provided  such  policies  and
               procedures  are  detailed  as to  the  particular  service  to be
               provided,  require the  Committee to be informed  about each such
               service prior to making pre-approval decisions and do not include
               delegation of the Committee's responsibilities to management. The
               Committee may delegate authority to grant  pre-approvals of audit
               services  and  permitted   non-audit  services  to  subcommittees
               consisting of one or more of its members, provided that decisions
               of such subcommittee to grant pre-approvals shall be presented to
               the full Committee at its next scheduled meeting.

          3.   Review with the independent auditors the scope of the prospective
               audit,  the  estimated  fees  therefore  and such  other  matters
               pertaining to such audit as the  Committee may deem  appropriate.
               Receive  copies  of the  annual  comments  from  the  independent
               auditors on accounting procedures and systems of control.

          4.   Review and discuss with management and the independent  auditors,
               before filing with the Commission,  the annual audited  financial
               statements  and  quarterly  financial  statements,  including the
               Company's disclosures under "Management's Discussion and Analysis
               of Financial  Condition and Results of Operations," and recommend
               to the Board whether the audited  financial  statements should be
               included in the Company's Form 10-K.

          5.   Review and discuss with management and the  independent  auditors
               the Company's earnings press releases  (including the use of "pro
               forma" or "adjusted" non-GAAP information),  as well as financial
               information and earnings guidance provided to analysts and rating
               agencies;  provided that the discussion of financial  information
               and earnings  guidance  provided to analysts and ratings agencies
               may  be  done  generally   (e.g.   discussion  of  the  types  of
               information  to be disclosed and the type of  presentation  to be
