"potential," "plan," "forecast," and similar terms. These statements represent
our intentions, plans, expectations and beliefs and are subject to risks,

and could cause actual results to differ materially from such forward-looking
statements. These factors include, among others:

    o general economic and business conditions in the United States as a whole
      and in the midwestern United States, and our service territory in
      particular;

    o governmental, statutory, regulatory or administrative initiatives
      affecting us or the United States electric or gas utility industries;

    o weather effects on sales and revenues;

    o general industry trends;

    o increased competition in the power generation and electric or gas
      utility industries;

    o fuel and power costs and availability;

    o changes in business strategy, development plans or vendor relationships;

    o availability, term and deployment of capital;

    o availability of qualified personnel;

    o risks relating to nuclear generation;

    o financial or regulatory accounting principles or policies imposed by the
      Financial Accounting Standards Board, the Securities and Exchange
      Commission, the Federal Energy Regulatory Commission and similar entities
      with regulatory oversight; and

    o other business or investment considerations that may be disclosed from
      time to time in our Securities and Exchange Commission filings or in

events or otherwise. The foregoing review of factors should not be construed as
exhaustive.

                                  RISK FACTORS


     Before you invest in any of the securities described in this prospectus,
you should be aware of the significant risks described below. You should
carefully consider these risks, together with all of the other information
included in this prospectus, the accompanying prospectus supplement and the
information incorporated by reference, before you decide to purchase our
securities.

     WE ARE ACTIVELY DEVELOPING AND CONSTRUCTING NEW FACILITIES, THE COMPLETION
AND EXPECTED COST OF WHICH IS SUBJECT TO SIGNIFICANT RISK.

     We are developing and constructing two new electric generating plants in
Iowa, and in the future we expect to pursue the development, construction,
ownership and operation of additional new or expanded facilities, the
completion of any of which is subject to substantial risk and may expose us to
significant costs. We cannot assure you that our development or construction
efforts on any particular project, or our efforts generally, will be
successful. Also, a proposed new or expanded facility may cost more than
planned to complete, and such excess costs, if found to be imprudent, may not
be recoverable in rates. The inability to avoid unsuccessful projects or to
recover any excess costs may materially affect our business, financial
position, results of operations and ability to service the securities.

     WE ARE SUBJECT TO OPERATING UNCERTAINTIES WHICH MAY ADVERSELY AFFECT OUR
FINANCIAL POSITION, RESULTS OF OPERATIONS AND ABILITY TO SERVICE THE
SECURITIES.

     The operation of a complex electric and gas utility (including generating,
transmission and distribution systems) involves many operating uncertainties
and events beyond our control. Operating risks include the breakdown or failure
of power generation equipment, compressors, pipelines, transmission and
distribution lines or other equipment or processes, fuel interruption,
performance below expected levels of output, capacity or efficiency, operator
error and catastrophic events such as severe storms, fires, earthquakes or
explosions. A casualty occurrence might result in injury or loss of life,
extensive property damage or environmental damage. Our revenues and expenses
may also be adversely affected by general economic, business, regulatory and
weather conditions. The realization of any of these risks could significantly
reduce or eliminate our revenues or significantly increase our expenses,
thereby adversely affecting our financial position, results of operations and
ability to service the securities.

     We currently possess property, business interruption, catastrophic and
general liability insurance, but proceeds from such insurance coverage may not
be adequate for all liabilities incurred, lost revenue or increased expenses.
Moreover, such insurance may not be available in the future at commercially
reasonable costs and on commercially reasonable terms. Changes in the insurance
markets subsequent to the September 11, 2001 terrorist attacks have made it
more difficult for us to obtain certain types of coverage. There can be no
assurance that we will be able to obtain the levels or types of insurance we
would otherwise have obtained prior to these market changes or that the
insurance coverage we do obtain will not contain large deductibles or fail to
cover certain hazards or that it will otherwise cover all potential losses.

     ACTS OF SABOTAGE AND TERRORISM AIMED AT OUR FACILITIES COULD ADVERSELY
EFFECT OUR BUSINESS.

     Since the September 11, 2001 terrorist attacks, the United States
government has issued warnings that energy assets, specifically our nation's
electric utility infrastructure, may be the future targets of terrorist
organizations. These developments have subjected our operations to increased
risks. Any future acts of sabotage or terrorism aimed at our facilities, or
those of our customers, could have a material adverse effect on our business,
financial condition, results of operations and ability to service the
securities. Any resulting acts of war or the threat of war as a result of such
terrorist attacks could adversely affect the economy and energy consumption.
Instability in the financial markets as a result of terrorism or war could also
materially adversely affect our ability to raise capital.


                                       5


     WE ARE SUBJECT TO COMPREHENSIVE ENERGY REGULATION AND CHANGES IN
REGULATION AND RATES MAY ADVERSELY AFFECT OUR BUSINESS, FINANCIAL CONDITION,
RESULTS OF OPERATIONS AND ABILITY TO SERVICE THE SECURITIES.

     We are subject to comprehensive regulation by various United States
federal, state and local regulatory agencies, all of which significantly
influences our operating environment, our rates, our capital structure, our
costs and our ability to recover our costs from customers. These regulatory
agencies include, among others, the Federal Energy Regulatory Commission, or
the FERC, the Environmental Protection Agency, the Nuclear Regulatory
Commission, the Iowa Utilities Board, or the IUB, the Illinois Commerce
Commission, other state utility boards and numerous local agencies. The FERC
has jurisdiction over, among other things, wholesale rates for electric
transmission service and electric energy sold in interstate commerce. United
States federal, state and local agencies also have jurisdiction over many of
our other activities. The utility commissions in the states where we operate
regulate many aspects of our operations including siting and construction of
facilities, customer service and the rates that we can charge customers.

     The structure of federal and state energy regulation is currently
undergoing change and has in the past, and may in the future, be the subject of
various challenges, initiatives and restructuring proposals by policy makers,
utilities and other industry participants. In addition to Congressional
initiatives, many states are implementing or considering regulatory initiatives
designed to increase competition in the domestic power generation industry and
increase access to electric utilities' transmission and distribution systems
for independent power producers and electricity consumers. The implementation
of regulatory changes in response to such challenges, initiatives and
restructuring proposals could result in the imposition of more comprehensive or
stringent requirements on us or other industry participants, which would result
in increased compliance costs and could have a material adverse effect on our
business, financial condition, results of operations and ability to service the
securities.

     We are unable to predict the impact on our operating results from the
future regulatory activities of any of these agencies or the Securities and
Exchange Commission under the Public Utility Holding Company Act of 1935, as
amended. Changes in regulations or the imposition of additional regulations
could have a material adverse impact on our results of operations. Recent
developments, events and uncertainties which have impacted or could impact our
businesses are described below.

     On July 31, 2002, the FERC issued a notice of proposed rulemaking with
respect to Standard Market Design for the electric industry. The FERC has
characterized the proposal as portending "sweeping changes" to the use and
expansion of the interstate transmission and wholesale bulk power systems in
the United States. The proposal includes numerous proposed changes to the
current regulation of transmission and generation facilities designed "to
promote economic efficiency" and replace the "obsolete patchwork we have
today," according to the FERC Chairman. The final rule, if adopted as currently
proposed, would require all public utilities operating transmission facilities
subject to the FERC jurisdiction to file revised open access transmission
tariffs that would require changes to the basic services these public utilities
currently provide. The proposed rule may impact the pricing of our electricity
and transmission products. The FERC does not envision that a final rule will be
fully implemented until September 30, 2004. We are still evaluating the
proposed rule, and we believe that the final rule could vary considerably from
the initial proposal. Accordingly, we are presently unable to quantify the
likely impact of the proposed rule on us.

     The state utility regulatory environment has to date, in general, given us
an exclusive right to serve retail electricity customers within our primary
service territory in Iowa and, in turn, the obligation to provide electric
service to those customers. There can be no assurance that there will not be a
change in legislation or regulation in Iowa or in any of the other states in
which we operate to allow retail competition in our service territory.

     We purchase gas supplies from producers and third party marketers. To
ensure system reliability, a geographically diverse supply portfolio with
varying terms and contract conditions is utilized for the gas supplies.


                                       6


     We have rights to firm pipeline capacity to transport gas to our service
territory through direct interconnects to the pipeline systems of Northern
Natural Gas Company (an affiliate), Natural Gas Pipeline Company of America,
Northern Border Pipeline Company and ANR Pipeline Company. Firm capacity in
excess of our system needs, resulting from differences between the capacity
portfolio and seasonal system demand, can be resold to other companies to
achieve optimum use of the available capacity. Past IUB and South Dakota Public
Utilities Commission rulings have allowed us to retain 30% of Iowa and South
Dakota margins, respectively, earned on the resold capacity, with the remaining
70% being returned to customers through a purchased gas adjustment clause as
described below.


     Our cost of gas is recovered from customers through purchased gas
adjustment clauses. In 1995, the IUB gave initial approval of our Incentive Gas
Supply Procurement Program. Under the program, as amended, we are required to
file with the IUB every six months a comparison of our gas procurement costs to
an index-based reference price. If our cost of gas for the period is less or
greater than an established tolerance band around the reference price, then we
share a portion of the savings or costs with our customers. The program has
been extended through October 31, 2003. A similar program is in effect in South
Dakota. Since the implementation of the program, we have successfully achieved
and shared savings with our natural gas customers.


     We utilize leased gas storage to meet peak day requirements and to manage
the daily changes in demand due to changes in weather. The storage gas is
typically replaced during the summer months. In addition, we also utilize three
liquefied natural gas plants and two propane-air plants to meet peak day
demands.

     We have strategically built multiple pipeline interconnections into
several of our larger communities. Multiple pipeline interconnects create
competition among pipeline suppliers for transportation capacity to serve those
communities, thus reducing costs. In addition, multiple pipeline interconnects
give us the ability to optimize delivery of the lowest cost supply from the
various pipeline supply basins into these communities and increase delivery
reliability. Benefits to our system customers are shared with all jurisdictions
through a consolidated purchased gas adjustment clause.

     WE ARE SUBJECT TO ENVIRONMENTAL, SAFETY AND OTHER LAWS AND REGULATIONS
WHICH MAY ADVERSELY IMPACT US.

     We are subject to a number of environmental, safety and other laws and
regulations affecting many aspects of our present and future operations,
including air emissions, water quality, wastewater discharges, solid wastes,
hazardous substances and safety matters. We may incur substantial costs and
liabilities in connection with our operations as a result of these regulations.
In particular, the cost of future compliance with federal, state and local
clean air laws, such as those that require certain generators, including some
of our electric generating facilities, to limit nitrogen oxide emissions and
potential other pollutants, may require us to make significant capital
expenditures which may not be recoverable through future rates. In addition,
these costs and liabilities may include those relating to claims for damages to
property and persons resulting from our operations. The implementation of
regulatory changes imposing more comprehensive or stringent requirements on us,
to the extent such changes would result in increased compliance costs or
additional operating restrictions, could have a material adverse effect on our
business, financial condition, results of operations and ability to service the
securities.

     In addition, regulatory compliance for existing facilities and the
construction of new facilities is a costly and time-consuming process, and
intricate and rapidly changing environmental regulations may require major
expenditures for permitting and create the risk of expensive delays or material
impairment of value if projects cannot function as planned due to changing
regulatory requirements or local opposition.

     In addition to operational standards, environmental laws also impose
obligations to clean up or remediate contaminated properties or to pay for the
cost of such remediation, often upon parties that did not actually cause the
contamination. Accordingly, we may become liable, either contractually or


                                       7


by operation of law, for remediation costs even if the contaminated property is
not presently owned or operated by us, or if the contamination was caused by
third parties during or prior to our ownership or operation of the property.
Given the nature of the past industrial operations conducted by us and others
at our properties, there can be no assurance that all potential instances of
soil or groundwater contamination have been identified, even for those
properties where an environmental site assessment or other investigation has
been conducted. Although we have accrued reserves for our known remediation
liabilities, future events, such as changes in existing laws or policies or
their enforcement, or the discovery of currently unknown contamination, may
give rise to additional remediation liabilities which may be material.

     Any failure to recover increased environmental or safety costs incurred by
us may have a material adverse effect on our business, financial condition,
results of operations and ability to service the securities.

     INCREASED COMPETITION RESULTING FROM LEGISLATIVE, REGULATORY AND
RESTRUCTURING EFFORTS COULD HAVE A SIGNIFICANT FINANCIAL IMPACT ON US AND
CONSEQUENTLY DECREASE OUR REVENUE.

     The energy market continues to move towards a competitive environment and
is characterized by numerous strong and capable competitors, many of which have
more extensive operating experience and greater financial resources than us.
Retail competition and the unbundling of regulated electric and gas service
could have a significant adverse financial impact on us due to an impairment of
assets, a loss of customers, lower profit margins and/or increased costs of
capital. The total impacts of restructuring may have a significant effect on
our financial position, results of operations and cash flows. We cannot predict
when we will be subject to changes in legislation or regulation, nor can we
predict the impacts of these changes on our financial position, results of
operations or cash flows.

     The generation segment of the electric industry has been and will be
significantly impacted by competition. The introduction of competition in the
wholesale market has resulted in a proliferation of power marketers and a
substantial increase in market activity. Many of these marketers have
experienced financial difficulties and the market continues to be volatile.


     As retail competition continues to evolve, margins will be pressured by
competition from other utilities, power marketers and self-generation. Many
states and the federal government are implementing or considering regulatory
initiatives that would increase access to electric utilities' transmission and
distribution systems for independent power producers, utilities, power
marketers and electricity customers. Although the recent and anticipated
changes in the United States electric utility industry may create
opportunities, they will also create additional challenges and risks for
utilities. Competition will put pressure on margins for traditional electric
services. Illinois recently enacted a law that provides for full retail
customer choice. While introduction of retail competition in Iowa is not
presently expected, depending upon the terms of any such legislation, if
introduced it could have a material adverse effect on us. These types of
restructurings and other industry restructuring efforts could materially impact
our results of operations in a manner which is difficult to predict, since such
efforts will depend on the terms and timing of such restructuring.


     WE ARE SUBJECT TO MARKET AND CREDIT RISK.

     We are exposed to market and credit risks in our operations. Specifically,
such risks include commodity price changes, market supply shortages, interest
rate changes and counterparty default. In Iowa, we do not have an ability to
pass through fuel price increases in our rates (an energy adjustment clause),
so any significant increase in fuel costs or purchased power costs could have a
negative impact on us. To minimize these risks, we require collateral to be
posted if the creditworthiness of counterparties deteriorates below established
levels and enter into financial derivative instrument contracts to hedge
purchase and sale commitments, fuel requirements and inventories of natural
gas, electricity, coal and emission allowances. However, financial derivative
instrument contracts do not eliminate the risk. The impact of these risks could
result in our inability to fulfill contractual obligations, significantly
higher energy or fuel costs relative to corresponding sales contracts or
increased interest expense.


                                       8


OUR GENERATING FACILITIES ARE DEPENDENT ON A LIMITED NUMBER OF SUPPLIERS AND
SERVICE PROVIDERS.

     Our electric generating facilities are often dependent on a single or
limited number of entities to supply or transport gas, coal or other fuels, to
dispose of wastes or to deliver electricity. The failure of any of these third
parties to fulfill its contractual obligations could increase the costs
incurred by us to provide electric service to our customers.

WE ARE SUBJECT TO THE UNIQUE RISKS ASSOCIATED WITH NUCLEAR GENERATIONS.

     The risks of nuclear generation include the following:

     (1) the potential harmful effects on the environment and human health
         resulting from the operation of nuclear facilities and the storage,
         handling and disposal of radioactive materials;

     (2) limitations on the amounts and types of insurance commercially
         available to cover losses that might arise in connection with nuclear
         operations; and

     (3) uncertainties with respect to the technological and financial aspects
         of decommissioning nuclear plants at the end of their licensed lives.

     The Nuclear Regulatory Commission has broad authority under federal law to
impose licensing and safety-related requirements for the operation of nuclear
generating facilities. In the event of non-compliance, the Nuclear Regulatory
Commission has the authority to impose fines or shut down a unit, or both,
depending upon its assessment of the severity of the situation, until
compliance is achieved. Revised safety requirements promulgated by the Nuclear
Regulatory Commission have, in the past, necessitated substantial capital
expenditures at nuclear plants, including those in which we have an ownership
interest, like the Quad Cities Generating Station described in the documents
incorporated by reference in this prospectus, and additional expenditures could
be required in the future. In addition, although we have no reason to
anticipate a serious nuclear incident at the units in which we have an
interest, if an incident did occur, it could have a material but presently
undeterminable adverse effect on our financial position, results of operations
and ability to service the securities.

                                USE OF PROCEEDS

     Unless otherwise specified in the applicable prospectus supplement, we
will use the net proceeds from the sale of the securities described in this
prospectus for general corporate purposes, which may include additions to
working capital, reductions of our indebtedness, refinancing of existing
securities and financing of capital expenditures. We may invest funds not
immediately required for such purposes in short-term securities. The amount and
timing of sales of the securities described in this prospectus will depend on
market conditions and the availability to us of other funds.

                         DESCRIPTION OF DEBT SECURITIES

     This prospectus describes the general terms and provisions of the debt
securities that we may offer. When we offer to sell a particular series of debt
securities, we will describe the specific terms of the series in a prospectus
supplement to this prospectus. We will also indicate in the applicable
prospectus supplement whether the general terms and provisions described in
this prospectus apply to a particular series of debt securities. We may also
sell hybrid or novel securities now existing or developed in the future that
combine certain features of debt securities and other securities described in
this prospectus.

GENERAL

     We may issue senior debt securities or subordinated debt securities. The
senior debt securities will be our direct secured or unsecured obligations and
the subordinated debt securities will be our direct unsecured obligations. Each
of the senior debt securities and the subordinated debt securities will be
issued under an indenture to be entered into between us and a trustee named in
the applicable prospectus supplement. The following summary of the indentures
is not a complete description of all of the provisions of the indentures. We
have filed (or will file prior to issuance of the applicable debt


                                       9


securities) forms of the indentures as exhibits to the registration statement
of which this prospectus is a part. Except to the extent set forth in a
prospectus supplement for a particular issue of debt securities, the indentures
for the debt securities, as amended or supplemented from time to time, will be
substantially similar to the indentures filed as exhibits to the registration
statement and described below.

     A prospectus supplement relating to a series of debt securities being
offered will include specific terms relating to the offering. These terms will
include some or all of the following:


     o the title of the series of debt securities;

     o whether the series of debt securities are senior debt securities or
       subordinated debt securities;

     o the aggregate principal amount (or any limit on the aggregate principal
       amount) of the series of debt securities and, if any debt securities of a
       series are to be issued at a discount from their face amount, the method
       of computing the accretion of such discount;

     o if other than the entire principal amount thereof, the portion of the
       principal amount of the debt securities payable upon declaration of
       acceleration of the maturity thereof;

     o the interest rate or method for calculation of the interest rate;

     o the date from which interest will accrue;

     o the record dates for principal and interest payable on debt securities;

     o the dates when, places where and manner in which principal and interest
       will be payable;

     o the securities registrar if other than the trustee;

     o the terms of any mandatory redemption (including any sinking fund
       requirement) or any redemption at our option;

     o the terms of any repurchase or remarketing rights of third parties;

     o the terms of any redemption at the option of holders of the debt
       securities;

     o the denominations in which the debt securities are issuable;

     o whether the debt securities will be issued in registered or bearer form
       and the terms of any such forms of debt securities;

     o whether the debt securities will be represented by a global security and
       the terms of any such global security;

     o the currency or currencies (including any composite currency) in which
       principal or interest or both may be paid;

     o if payments of principal or interest may be made in a currency other
       than that in which the debt securities are denominated, the method for
       determining such payments;

     o provisions for electronic issuance of debt securities or issuance of
       debt securities in certificated form;

     o any events of default, covenants and/or defined terms in addition to or
       in lieu of those set forth in the applicable indenture;

     o whether and upon what terms debt securities may be defeased;

     o whether the debt securities will have guaranties;

     o any special tax implications of the debt securities; and

     o any other terms in addition to or different from those contained in the
       applicable indenture.

     The debt securities will bear no interest or interest at a fixed or a
floating rate. Debt securities bearing no interest or interest at a rate that
at the time of issuance is below the prevailing market rate may be sold or
deemed to be sold at a discount below their stated principal amount. With
respect to


                                       10


any debt securities as to which we have the right to defer interest, the
holders of such debt securities may be allocated interest income for federal
and state income tax purposes without receiving equivalent, or any, interest
payments. Any material federal income tax consequences applicable to any such
discounted debt securities or to debt securities issued at par that are treated
as having been issued at a discount for federal income tax purposes will be
described in the applicable prospectus supplement.

SUBORDINATION OF SUBORDINATED DEBT SECURITIES

     The subordinated debt securities will be subordinate and junior in right
of payment to our senior debt, including the senior debt securities described
in this prospectus. Unless otherwise specified in the applicable prospectus
supplement, no payments on the subordinated debt securities may be made if (1)
any senior debt is not paid when due or (2) the maturity of any senior debt has
been accelerated because of a default. Upon any distribution of our assets to
creditors upon a bankruptcy, insolvency, liquidation, reorganization or similar
event with respect to us, all amounts due on our senior debt must be paid
before any payments are made on the subordinated debt securities.

     Subject to the payment in full of all senior debt, the rights of the
holders of subordinated debt securities will be subrogated to the rights of the
holders of our senior debt to receive payments or distributions applicable
thereto until all amounts owing on the subordinated debt securities are paid in
full.

     The subordinated indenture will not limit the amount of senior debt that
we can incur.

GLOBAL SECURITIES

 BOOK-ENTRY SYSTEM

     The debt securities will be issued under a book-entry system in the form
of one or more global securities. Each global security will be deposited with,
or on behalf of, a depositary, which will be The Depository Trust Company, New
York, New York. The global securities will be registered in the name of the
depositary or its nominee.

     The debt securities will not be issued in certificated form and, except
under the limited circumstances described below, owners of beneficial interests
in the global securities will not be entitled to physical delivery of the debt
securities in certificated form. The global securities may not be transferred
except as a whole by the depositary to a nominee of the depositary or by a
nominee of the depositary to the depositary or another nominee of the
depositary or by the depositary or any nominee to a successor of the depositary
or a nominee of such successor.

     The depositary is a limited-purpose trust company organized under the New
York Banking Law, a "banking organization" within the meaning of the New York
Banking Law, a member of the Federal Reserve System, a "clearing corporation"
within the meaning of the New York Uniform Commercial Code, and a "clearing
agency" registered pursuant to the provisions of Section 17A of the Exchange
Act. The depositary holds securities that its direct participants deposit with
the depositary. The depositary also facilitates the settlement among direct
participants of securities transactions, such as transfers and pledges, in
deposited securities through electronic computerized book-entry changes in
direct participants' accounts, thereby eliminating the need for physical
movement of securities certificates. Direct participants include securities
brokers and dealers, banks, trust companies, clearing corporations and certain
other organizations, including Euroclear Bank as operator of The Euroclear
System and Clearstream Banking societe anonyme. The depositary is owned by a
number of its direct participants and by the New York Stock Exchange, Inc., the
American Stock Exchange, Inc. and NASD, Inc. Access to the depositary system is
also available to indirect participants such as securities brokers and dealers,
banks and trust companies that clear through or maintain a custodial
relationship with a direct participant, either directly or indirectly. The
rules applicable to the depositary and its direct and indirect participants are
on file with the Securities and Exchange Commission.

     Purchases of the debt securities under the depositary system must be made
by or through direct participants, which will receive a credit for the debt
securities on the depositary's records. The


                                       11


ownership interest of each actual purchaser and beneficial owner of each debt
security is in turn to be recorded on the direct and indirect participants'
records. Beneficial owners will not receive written confirmation from the
depositary of their purchase, but beneficial owners are expected to receive
written confirmations providing details of the transaction, as well as periodic
statements of their holdings, from the direct or indirect participant through
which the beneficial owner entered into the transaction. Transfers of ownership
interests in the debt securities are to be accomplished by entries made on the
books of direct and indirect participants acting on behalf of beneficial
owners. Beneficial owners will not receive certificates representing their
ownership interests in debt securities, except in the event that use of the
book-entry system for the debt securities is discontinued.

     To facilitate subsequent transfers, all debt securities deposited by
direct participants with the depositary will be registered in the name of the
depositary's partnership nominee, Cede & Co., or such other name as may be
requested by an authorized representative of the depositary. The deposit of
debt securities with the depositary and their registration in the name of Cede
& Co. or such other nominee effect no change in beneficial ownership. The
depositary has no knowledge of the actual beneficial owners of the debt
securities; the depositary's records reflect only the identity of the direct
participants to whose accounts such debt securities are credited, which may or
may not be the beneficial owners. The direct and indirect participants will
remain responsible for keeping account of their holdings on behalf of their
customers.

     Conveyance of notices and other communications by the depositary to direct
participants, by direct participants to indirect participants, and by direct
participants and indirect participants to beneficial owners will be governed by
arrangements among them, subject to any statutory or regulatory requirements as
may be in effect from time to time.

     Neither the depositary nor Cede & Co. (nor such other nominee of the
depositary) will consent or vote with respect to the debt securities. Under its
usual procedures, the depositary mails an omnibus proxy to us as soon as
possible after the record date. The omnibus proxy assigns Cede & Co.'s
consenting or voting rights to those direct participants to whose accounts the
debt securities are credited on the record date (identified in a listing
attached to the omnibus proxy).

     Principal (and premium, if any) and interest payments on the debt
securities and any redemption payments will be made to Cede & Co. (or such
other nominee as may be requested by an authorized representative of the
depositary). The depositary's practice is to credit direct participants'
accounts upon the depositary's receipt of funds and corresponding detail
information from us or our agent on the payable date in accordance with the
direct participants' respective holdings shown on the depositary's records.
Payments by participants to beneficial owners will be governed by standing
instructions and customary practices, as is the case with securities held for
the accounts of customers in bearer form or registered in "street name," and
will be the responsibility of such participant and not of the depositary, the
trustee, or us or our agent, subject to any statutory or regulatory
requirements as may be in effect from time to time. Payment of principal (and
premium, if any), interest and any redemption proceeds to Cede & Co. (or such
other nominee as may be requested by an authorized representative of the
depositary) is our responsibility, disbursements of such payments to direct
participants is the responsibility of the depositary, and disbursement of such
payments to the beneficial owners is the responsibility of direct and indirect
participants.

     The depositary may discontinue providing its services as securities
depositary with respect to the debt securities at any time by giving reasonable
notice to us. Under such circumstances, in the event that a successor
securities depositary is not obtained, certificated debt securities are
required to be printed and delivered. We may decide to discontinue use of the
system of book-entry transfers through the depositary (or a successor
securities depositary). In that event, certificated debt securities will be
printed and delivered.

     The information in this section concerning the depositary and the
depositary's book-entry system has been obtained from sources that we believe
to be reliable, but we take no responsibility for the accuracy thereof.


                                       12


 EXCHANGE OF GLOBAL SECURITIES FOR CERTIFICATED SECURITIES

     Except as otherwise may be set forth in the applicable prospectus
supplement, the global securities may be exchanged for debt securities in
certificated form only in the following circumstances:

     (1) if the depositary notifies us that it is unwilling or unable to
         continue as depositary for the global securities, or if the depositary
         is no longer registered as a clearing agency under the Securities
         Exchange Act, and we do not appoint a replacement depositary within 90
         days;

     (2) an event of default under the applicable indenture occurs; or

     (3) if we determine that an issue of debt securities will no longer be
         represented by global securities.

     If any global securities are exchangeable for certificated securities as
described above, we will execute, and the trustee will authenticate upon our
order, certificated securities of like tenor and terms in certificated form in
an aggregate principal amount equal to the principal amount of such global
securities. These certificated securities will be delivered to persons
specified by the depositary in exchange for the beneficial interests in the
global securities being exchanged.


REDEMPTION AND REPAYMENT

     The applicable prospectus supplement will specify the following:

     o if the debt securities are subject to any sinking fund and the terms of
       any such sinking fund;

     o if we may elect to redeem the debt securities prior to maturity and the
       terms of any such optional redemption;

     o if we will be required to redeem the securities prior to maturity upon
       the occurrence of certain events and the terms of any such mandatory
       redemption; or

     o if the holders of the debt securities will have the right to repayment
       of the debt securities prior to maturity and the terms of any such
       optional repayment.

     If we elect or are required to redeem debt securities, a redemption notice
will be sent to each holder of debt securities to be redeemed at least 30 but
not more than 60 days prior to the redemption date. The redemption notice will
include the following: (1) the redemption date, the places of redemption and
the redemption price; (2) a statement that payment of the redemption price will
be made on surrender of the debt securities at the places of redemption; (3) a
statement that accrued interest to the redemption date will be paid as
specified in the notice and that after the redemption date interest will cease
to accrue; (4) if less than all of the debt securities of a series are to be
redeemed, the particular debt securities or portions thereof to be redeemed;
(5) if any debt securities are to be redeemed in part only, the portion of the
debt securities to be redeemed and a statement that, upon surrender of the debt
securities for redemption, new debt securities having the same terms will be
issued in an amount equal to the unredeemed portion; and (6) if applicable, a
statement that redemption is subject to the receipt by the trustee prior to the
redemption date of sufficient funds to make such redemption.

     If notice of redemption is given as specified above, the debt securities
called for redemption will become due and payable on the date and at the places
stated in the notice at the applicable redemption price, together with accrued
interest to the redemption date. After the redemption date, the debt securities
subject to redemption will cease to bear interest and will not be entitled to
the benefits of the applicable indenture, other than the right to receive
payment of the redemption price together with accrued interest to the
redemption date.

     If debt securities are repayable at the option of the holders prior to
maturity, a holder that elects to have its debt securities repaid will be
required to deliver such debt securities (or a guarantee of delivery from an
eligible institution) to the trustee at least 30 but not more than 45 days
prior to the repayment date. For debt securities represented by global
securities held by the depositary, the


                                       13


repayment option may be exercised by a direct participant in the depositary on
behalf of the beneficial owner by sending written notice to the trustee
(specifying certain information regarding the debt securities to be repaid) at
least 30 but not more than 60 days prior to the repayment date.


COVENANTS

     In addition to other covenants, if any, as may be described in the
applicable prospectus supplement and except as may otherwise be set forth in
the applicable prospectus supplement, the indentures will contain the following
covenants:

     o a covenant which requires us to maintain an office for payment and
       registration of transfer or exchange of the debt securities in New York,
       New York;

     o a covenant which requires us to notify the trustee in writing of any
       event of default under an indenture within five days after we become
       aware of such event of default;

     o a covenant which requires us to maintain our corporate existence, rights
       and franchises, unless the maintenance of such rights and franchises is
       no longer desirable in the conduct of our business; and

     o a covenant which prohibits us from consolidating with or merging with or
       into any other person or conveying, transferring or leasing our
       properties substantially as an entirety to any other person, unless the
       surviving company or transferee, as applicable, is a U.S. company and
       assumes all of our obligations under the indenture.


EVENTS OF DEFAULT

     Except as described in the applicable prospectus supplement, the following
events will constitute events of default under the applicable indenture:

     o we fail to pay interest on the debt securities and such failure
       continues for 30 days;

     o we fail to pay principal of the debt securities when due;

     o we breach any other covenant or representation in the indenture and such
       breach continues for 60 days (such period to be extended to up to 90 days
       if we are diligently pursuing a cure) after we receive a notice of
       default with respect thereto;

     o we default in the payment of any indebtedness other than the debt
       securities in excess of $75,000,000, or we breach any other provision of
       such indebtedness and such breach results in an acceleration of such
       indebtedness, and in each case such indebtedness is not discharged or
       such acceleration is not rescinded, as applicable, within 90 days after
       we receive a notice of default with respect thereto;

     o a final non-appealable judgment for the payment of money in excess of
       $75,000,000 is entered against us and is not discharged or satisfied
       within 90 days after we receive a notice of default with respect thereto;


     o a decree or order is entered against us in an involuntary bankruptcy
       proceeding and is not vacated in 90 days, or a similar involuntary event
       relating to our bankruptcy or insolvency occurs and continues for 90
       days; and

     o we commence a voluntary bankruptcy case or take similar voluntary
       actions relating to our bankruptcy or insolvency.

     Upon the occurrence of an event of default under an indenture, the holders
of at least a majority in aggregate principal amount of the applicable debt
securities may declare such debt securities to be immediately due and payable.
Holders of a majority in principal amount of such debt securities may rescind
the acceleration so long as the conditions set forth in the applicable
indenture have been satisfied.


                                       14


     Prior to acceleration, holders of a majority in aggregate principal amount
of an issuance of debt securities may waive an event of default, other than (1)
an event of default related to non-payment of principal or interest and (2) an
event of default related to a covenant or other provision of the indenture that
cannot be modified without the consent of each holder of debt securities
affected thereby.


MODIFICATIONS TO THE INDENTURE

     Except as otherwise set forth in the applicable prospectus supplement,
each indenture will contain provisions which allow us and the trustee to amend
the indenture without the consent of any holder of debt securities for the
following purposes:

     o to cure ambiguities or to cure, correct or supplement any defective or
       inconsistent provisions;

     o to add additional covenants, events of default or collateral, or to
       surrender a right or power conferred upon us in the indenture;

     o to establish the form of additional debt securities in accordance with
       the terms of the indenture;

     o to evidence the succession of another company to us and the assumption
       by the successor of our obligations under the indenture;

     o to grant to or confer upon the trustee for the benefit of the holders
       any additional rights, remedies, powers or authority;

     o to permit the trustee to comply with any duties imposed upon it by law;

     o to specify further the duties and responsibilities of, and to define
       further the relationships among, the trustee and any authenticating agent
       or paying agent for the debt securities; and

     o to change or eliminate any of the provisions of the indenture, so long
       as the change or elimination becomes effective only when there are no
       debt securities outstanding that were created prior to the execution of
       the supplemental indenture or other document evidencing such change or
       elimination.

     Except as set forth in the applicable prospectus supplement, each
indenture will contain provisions which allow us and the trustee to amend the
indenture for any other purpose with the consent of holders of a majority in
principal amount of the applicable issue of debt securities, other than
amendments which (1) extend the stated maturity of the debt securities, (2)
reduce the principal amount of the debt securities, (3) reduce the interest
rate for the debt securities, (4) extend the dates for scheduled payments of
principal and interest, (5) impair the right of a holder of debt securities to
institute suit for the payment of its debt securities, or (6) reduce the
percentage of holders of debt securities required to consent to amendments or
waive defaults under the indenture. The items described in (1) through (5)
above will require the consent of all holders affected by the change. The item
described in (6) above will require the consent of all holders.

GOVERNING LAW

     The senior indenture and the subordinated indenture will be governed by
the laws of the State of New York.

                         DESCRIPTION OF CAPITAL STOCK


     We have the authority under our articles of incorporation to issue
350,000,000 shares of common stock, no par value, and 100,000,000 shares of
preferred stock, no par value. As of December 31, 2002, 70,980,203 shares of
our common stock were outstanding, all of which are owned by MHC Inc. The
common stock is not listed on any exchange. All outstanding shares of common
stock are fully paid and non-assessable.



                                       15



     Also as of December 31, 2002, the following shares of our preferred stock
were outstanding: 49,451 shares of the $3.30 series; 38,305 shares of the $3.75
series; 32,630 shares of the $3.90 series; 47,362 shares of the $4.20 series;
49,945 shares of the $4.35 series; 50,000 shares of the $4.40 series; and
49,898 shares of the $4.80 series. All outstanding shares of preferred stock
are fully paid and non-assessable. The terms of these preferred securities are
described in an amendment to our articles of incorporation which is
incorporated herein by reference.


COMMON STOCK

     The shares of our authorized common stock are identical in all respects
and have equal rights and privileges. Each holder of our common stock is
entitled to one vote in the election of directors and other matters. Common
shareholders may receive dividends when declared by our board of directors.
Dividends may be paid in cash, stock or another form. In certain cases, common
shareholders may not receive dividends until we have satisfied our obligations
to any preferred shareholders. If we liquidate, dissolve or wind-up our
business, either voluntarily or not, common shareholders will share equally in
the assets remaining after we pay our creditors and preferred shareholders.


PREFERRED STOCK

     We may issue, from time to time, shares of one or more series or classes
of our preferred stock with such preferences and designations as our board of
directors may determine. The following summary description sets forth some of
the general terms of the preferred stock. We will describe the specific terms
of any series of preferred stock that we issue in a prospectus supplement. To
the extent the description contained in the prospectus supplement differs from
this summary description, you should rely on the information in the prospectus
supplement. You should also read our articles of incorporation and bylaws
before purchasing the preferred stock.

     Our board of directors is authorized to determine for each series of
preferred stock, and the applicable prospectus supplement will set forth with
respect to any such series:

     o the designation of such series and the number of shares that constitute
       such series;

     o the dividend rate (or the method of calculation thereof), if any, on the
       shares of such series and the priority as to payment of dividends with
       respect to other classes or series of our capital stock;

     o the dividend periods (or the method of calculating the dividend
       periods);

     o the voting rights of the shares, if any;

     o the liquidation preference and the priority as to payment of such
       liquidation preference with respect to the classes or series of preferred
       stock and any other rights of the shares of such series if we liquidate,
       dissolve or wind-up our affairs;

     o whether and on what terms we can redeem or repurchase the shares of
       preferred stock;

     o whether the preferred stock of such series will have the benefit of a
       sinking fund; and

     o any other material terms.

     The shares of a series of preferred stock will not have any preferences,
voting powers or relative, participating, optional or other special rights
except as set forth above or in the applicable prospectus supplement, our
articles of incorporation or the applicable certificate of designation or as
otherwise required by law.

     Except as set forth in the applicable prospectus supplement, no series of
preferred stock will be redeemable or receive the benefit of a sinking fund. If
we voluntarily or involuntarily liquidate, dissolve or wind up our affairs, the
holders of each series of preferred stock will be entitled to receive the
liquidation preference per share specified in the prospectus supplement plus
any accrued and unpaid dividends. Holders of preferred stock will be entitled
to receive these amounts before any


                                       16


distribution is made to the holders of common stock, but only after the
liquidation preference has been fully paid on any shares of senior ranking
preferred stock, if any. Neither the par value nor the liquidation preference
is indicative of the price at which the preferred stock will actually trade on
or after the date of issuance.

     We will designate the transfer agent for each series of preferred stock in
the applicable prospectus supplement.

                              PLAN OF DISTRIBUTION

     We may offer and sell or exchange the securities described in this
      prospectus:

     o through agents,

     o through one or more underwriters,

     o through one or more dealers,

     o directly to one or more purchasers (through a specific bidding or
       auction process or otherwise), or

     o through a combination of any such methods of sale.

     The distribution of the securities described in this prospectus may be
effected from time to time in one or more transactions either:

     o at a fixed price or prices, which may be changed,

     o at market prices prevailing at the time of sale,

     o at prices relating to such prevailing market prices,

     o at negotiated prices, or

     o at a fixed exchange ratio in return for other of our securities.

     Offers to purchase or exchange the securities may be solicited by agents
designated by us from time to time. Any such agent will be named, and any
commissions payable by us to such agent will be set forth, in the applicable
prospectus supplement. Unless otherwise indicated in the applicable prospectus
supplement, any such agent will be acting on a best efforts basis for the
period of its appointment. Any such agent may be deemed to be an underwriter,
as that term is defined in the Securities Act, of the securities so offered and
sold.

     If an underwriter or underwriters are utilized in the sale of the
securities, we will execute an underwriting agreement with such underwriter or
underwriters at the time an agreement for such sale is reached. The names of
the specific managing underwriter or underwriters, as well as any other
underwriters, and the terms of the transactions, including compensation of the
underwriters and dealers, which may be in the form of discounts, concessions or
commissions, if any, will be set forth in the applicable prospectus supplement,
which will be used by the underwriters to make resales of the securities.

     If a dealer is utilized in the sale of the securities, we or an
underwriter will sell such securities to the dealer as principal. The dealer
may then resell such securities to the public at varying prices to be
determined by such dealer at the time of resale. The name of the dealer and the
terms of the transactions will be set forth in the applicable prospectus
supplement relating thereto.

     Offers to purchase or exchange the securities may be solicited directly by
us and sales or exchanges thereof may be made by us directly to institutional
investors or others. The terms of any such sales, including the terms of any
bidding or auction process, if utilized, will be described in the applicable
prospectus supplement relating thereto.

     We may enter into agreements with agents, underwriters and dealers under
which we agree to indemnify them against certain liabilities, including
liabilities under the Securities Act, or to contribute


                                       17


to payments they may be required to make in respect thereof. The terms and
conditions of such indemnification or contribution will be described in the
applicable prospectus supplement. Certain of the agents, underwriters or
dealers, or their affiliates, may be customers of, engage in transactions with
or perform services for us in the ordinary course of business.

                                 LEGAL MATTERS

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS


     Sections 490.850-490.859 of the Iowa Business Corporation Act permit
corporations organized thereunder to indemnify directors, officers, employees
and agents against liability under certain circumstances. The Restated Articles
of Incorporation, as amended, and the Restated Bylaws, as amended, of
MidAmerican Energy Company provide for indemnification of directors, officers
and employees to the full extent provided by the Iowa Business Corporation Act.
The Articles of Incorporation and the Bylaws state that the indemnification

purchase and maintain insurance on behalf of any person who is or was a
director, officer, employee or agent of MidAmerican Energy Company or another
corporation, partnership, joint venture, trust or other enterprise against any
expense, liability or loss, whether or not MidAmerican Energy Company would
have the power to indemnify such person against such expense, liability or loss
under the Iowa Business Corporation Act. Pursuant to Section 490.857 of the
Iowa Business Corporation Act, the Articles of Incorporation and the Bylaws,
MidAmerican Energy Company, through MidAmerican Energy Holdings Company,
maintains directors' and officers' liability insurance coverage. MidAmerican
Energy Company has also entered into indemnification agreements with certain
directors and officers, and expects to enter into similar agreements with
future directors and officers, to further assure such persons indemnification
as permitted by Iowa law.

     As permitted by Section 490.202 of the Iowa Business Corporation Act and
Article XI.B. of the Articles of Incorporation, the Articles of Incorporation
are deemed to provide that no director shall be personally liable to
MidAmerican Energy Company or its shareholders for money damages for any action
taken, or any failure to take any action, as a director, except liability for
any of the following: (1) the amount of a financial benefit received by a
director to which the director is not entitled; (2) an intentional infliction
of harm on the corporation or the shareholders; (3) a violation of section
490.833 (relating to certain unlawful distributions to shareholders); or, (4)
an intentional violation of criminal law.


     The form of distribution agreement filed as Exhibit 1.1 hereto and the
form of underwriting agreement filed as Exhibit 1.2 hereto include provisions
requiring the underwriters, dealers or agents, as applicable, to indemnify
directors, officers and certain controlling persons of MidAmerican Energy
Company in certain circumstances.

                      Registration No. 1-11505)



ITEM 17. UNDERTAKINGS

     The undersigned registrant hereby undertakes:

     (1) To file, during any period in which offers or sales are being made, a
post-effective amendment to this registration statement:

          (i) To include any prospectus required by Section 10(a)(3) of the
     Securities Act of 1933;

          (ii) To reflect in the prospectus any facts of events arising after
     the effective date of the registration statement (or the most recent
     post-effective amendment thereof) which, individually or in the aggregate,
     represent a fundamental change in the information set forth in the
     registration statement. Notwithstanding the foregoing, any increase or
     decrease in volume of securities offered (if the total dollar value of
     securities offered would not exceed that which was registered) and any
     deviation from the low or high end of the estimated maximum offering range
     may be reflected in the form of prospectus filed with the Commission
     pursuant to Rule 424(b) under the Securities Act if, in the aggregate, the
     changes in volume and price present no more than a 20% change in the
     maximum aggregate offering price set forth in the "Calculation of
     Registration Fee" table in the effective registration statement;

          (iii) To include any material information with respect to the plan of
     distribution not previously disclosed in the registration statement or any
     material change to such information in the registration statement;

     provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) above do not
     apply if the information

                                      II-2


    required to be included in a post-effective amendment by those paragraphs
    is contained in periodic reports filed with or furnished to the Commission
    by the Registrant pursuant to Section 13 or 15(d) of the Securities
    Exchange Act of 1934 that are incorporated by reference in the
    registration statement.

     (2) That, for the purpose of determining any liability under the
Securities Act of 1933, each such post-effective amendment shall be deemed to
be a new registration statement relating to the securities offered therein, and
the offering of such securities at the time shall be deemed to be the initial
bona fide offering thereof.

     (3) To remove from registration by means of a post-effective amendment any
of the securities being registered which remain unsold at the termination of
the offering.

     (4) That, for purposes of determining any liability under the Securities
Act of 1933, each filing of the registrant's annual report pursuant to Section
13(a) or 15(d) of the Securities Exchange Act of 1934 that is incorporated by
reference in this registration statement shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

     (5) To file an application for the purpose of determining the eligibility
of the trustee to act under subsection (a) of Section 310 of the Trust
Indenture Act of 1939 in accordance with the rules and regulations prescribed
by the Commission under Section 305(b)(2) of the Trust Indenture Act of 1939.

     (6) Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers and controlling
persons of the registrant pursuant to the provisions referred to in Item 15 of
this registration statement, or otherwise, the registrant has been advised that
in the opinion of the Securities and Exchange Commission such indemnification
is against public policy as expressed in the Securities Act of 1933 and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the registrant of expenses incurred
or paid by a director, officer or controlling person of the registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the
matter has been settled by controlling precedent, submit to a court of
appropriate jurisdiction the question whether such indemnification by it is
against public policy as expressed in the Securities Act and will be governed
by the final adjudication of such issue.


                                      II-3


                                  SIGNATURES


     Pursuant to the requirements of the Securities Act of 1933, as amended, the
registrant certifies that it has reasonable grounds to believe that it meets all
of the requirements for filing on Form S-3 and has duly caused this
post-effective amendment no. 1 to be signed on its behalf by the undersigned,
thereunto duly authorized, in the City of Des Moines, State of Iowa, on April 9,
2003.
