Information.

                                 USE OF PROCEEDS

      The net  proceeds  from the  sale of the  notes  will be used for  general
corporate  purposes  relating to our utility  business.  These purposes  include
redeeming or repurchasing  outstanding  debt or preferred stock and replenishing
working capital. If we do not use the net proceeds  immediately,  we temporarily
invest them in short-term,  interest-bearing  obligations.  We estimate that our
construction costs in 1999 will approximate $151,800,000. At September 30, 1999,
our outstanding short-term debt was $190,850,000.

                            DESCRIPTION OF THE NOTES

General

      We will  issue the notes  under an  Indenture  dated  October  1, 1998 (as
previously supplemented and amended) between us and the Trustee, The Bank of New
York. This prospectus briefly outlines some provisions of the Indenture.  If you
would like more information on these provisions, you should review the Indenture
and any  supplemental  indentures  or company  orders that we have filed or will
file with the SEC.  See Where  You Can Find  More  Information  on how to locate
these documents. You may also review these documents at the Trustee's offices at
101 Barclay Street, New York, New York.

      The Indenture  does not limit the amount of notes that may be issued.  The
Indenture  permits us to issue notes in one or more series or tranches  upon the
approval  of our board of  directors  and as  described  in one or more  company
orders or supplemental  indentures.  Each series of notes may differ as to their
terms.

      The  notes are  unsecured  and will rank  equally  with all our  unsecured
unsubordinated  debt.  Substantially  all of our fixed properties and franchises
are subject to the lien of our first  mortgage bonds issued under and secured by
an  Indenture  of  Mortgage  and Deed of  Trust,  dated as of June 1,  1939,  as
previously supplemented and amended, between us and



The Bank of New York,  formerly  Irving Trust Company,  as trustee.  For current
information on our debt outstanding see our most recent Form 10-K and 10-Q.
See Where You Can Find More Information.

      The notes will be  denominated  in U.S.  dollars and we will pay principal
and  interest  in U.S.  dollars.  Unless an  applicable  pricing  or  prospectus
supplement  states  otherwise,  the notes will not be subject to any conversion,
amortization,  or sinking fund.  We expect that the notes will be  "book-entry,"
represented by a permanent  global note registered in the name of The Depository
Trust  Company,  or its nominee.  We reserve the right,  however,  to issue note
certificates registered in the name of the noteholders.

      In the discussion that follows, whenever we talk about paying principal on
the notes,  we mean at maturity or redemption.  Also, in discussing the time for
notices and how the different  interest rates are calculated,  all times are New
York City time and all references to New York mean the City of New York,  unless
otherwise noted.

      The following  terms may apply to each note as specified in the applicable
pricing or prospectus supplement and the note.

Redemptions

      If we issue  redeemable  notes,  we may  redeem  such  notes at our option
unless an applicable  pricing or prospectus  supplement  states  otherwise.  The
pricing or  prospectus  supplement  will state the terms of  redemption.  We may
redeem notes in whole or in part by delivering written notice to the noteholders
no more than 60, and not less than 30,  days prior to  redemption.  If we do not
redeem all the notes of a series at one time,  the Trustee  selects the notes to
be redeemed in a manner it determines to be fair.

Remarketed Notes

      If we issue notes with  remarketing  features,  an  applicable  pricing or
prospectus supplement will describe the terms for the notes including:  interest
rate, remarketing  provisions,  our right to redeem notes, the holders' right to
tender notes, and any other provisions.

Book-Entry Notes - Registration, Transfer, and Payment of Interest and Principal

      Book-entry  notes of a series  will be issued in the form of a global note
that the Trustee will deposit with The Depository  Trust Company,  New York, New
York  ("DTC").  This  means  that we will not issue  note  certificates  to each
holder.  One or  more  global  notes  will be  issued  to DTC  who  will  keep a
computerized record of its participants (for example, your broker) whose clients
have purchased the notes. The participant will then keep a record of its clients
who purchased  the notes.  Unless it is exchanged in whole or in part for a note
certificate,  a  global  note  may not be  transferred,  except  that  DTC,  its
nominees,  and their  successors  may  transfer a global  note as a whole to one
another.

      Beneficial  interests in global  notes will be shown on, and  transfers of
global  notes  will be made  only  through,  records  maintained  by DTC and its
participants.

      DTC has provided us the following  information:  DTC 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 United  States
Federal Reserve System, a "clearing  corporation"  within the meaning of the New
York  Uniform  Commercial  Code and a  "clearing  agency"  registered  under the
provisions  of Section 17A of the  Securities  Exchange  Act of 1934.  DTC holds
securities that its participants



("Direct  Participants") deposit with DTC. DTC also records the settlement among
Direct Participants of securities  transactions,  such as transfers and pledges,
in deposited  securities through  computerized  records for Direct Participant's
accounts.  This  eliminates  the  need to  exchange  note  certificates.  Direct
Participants  include  securities  brokers and dealers,  banks, trust companies,
clearing corporations and certain other organizations.

      Other  organizations  such as  securities  brokers and dealers,  banks and
trust companies that work through a Direct Participant also use DTC's book-entry
system.  The rules that apply to DTC and its  participants  are on file with the
SEC.

      A number of its Direct Participants and the New York Stock Exchange,
Inc., The American Stock Exchange, Inc. and the National Association of
Securities Dealers, Inc. own DTC.

      We will wire principal and interest payments to DTC's nominee.  We and the
Trustee  will  treat  DTC's  nominee  as the owner of the  global  notes for all
purposes.  Accordingly, we, the Trustee and any paying agent will have no direct
responsibility  or liability to pay amounts due on the global notes to owners of
beneficial interests in the global notes.

      It is DTC's current practice,  upon receipt of any payment of principal or
interest, to credit Direct Participants'  accounts on the payment date according
to their  respective  holdings of  beneficial  interests  in the global notes as
shown on DTC's records. In addition,  it is DTC's current practice to assign any
consenting or voting rights to Direct  Participants  whose accounts are credited
with notes on a record date. The customary  practices  between the  participants
and owners of  beneficial  interests  will govern  payments by  participants  to
owners of beneficial  interests in the global notes and voting by  participants,
as is the case with  notes  held for the  account  of  customers  registered  in
"street name." However,  payments will be the responsibility of the participants
and not of DTC, the Trustee or us.

      DTC management is aware that some computer  applications,  systems and the
like for processing  data  ("Systems")  that are dependent upon calendar  dates,
including  dates before,  on and after January 1, 2000, may encounter "Year 2000
problems".  DTC has informed its Direct  Participants  and other  members of the
financial community (the "Industry") that it has developed and is implementing a
program  so that its  Systems,  as the same  relate  to the  timely  payment  of
distributions  (including  principal  and income  payments) to  securityholders,
book-entry  deliveries  and  settlement of trades  within DTC ("DTC  Services"),
continue to function appropriately. This program includes a technical assessment
and a  remediation  plan,  each of which is complete.  Additionally,  DTC's plan
includes a testing phase,  which is expected to be completed within  appropriate
time frames.

      However,  DTC's ability to perform properly its services is also dependent
upon other  parties,  including but not limited to issuers and their agents,  as
well as third party vendors from whom DTC licenses  software and  hardware,  and
third  party  vendors on whom DTC relies for  information  or the  provision  of
services,  including telecommunication and electrical utility service providers,
among  others.  DTC has informed the Industry  that it is  contacting  (and will
continue to contact) third party vendors from whom DTC acquires services to: (i)
impress upon them the importance of such services being Year 2000 compliant; and
(ii)  determine the extent of their efforts for Year 2000  remediation  (and, as
appropriate,



testing) of their services.  In addition, DTC is in the process of developing
such contingency plans as it deems appropriate.

      According to DTC, the foregoing  information  with respect to DTC has been
provided to the Industry for informational  purposes only and is not intended to
serve as a representation, warranty or contract modification of any kind.

      Notes  represented  by  a  global  note  will  be  exchangeable  for  note
certificates with the same terms in authorized denominations only if:

     DTC notifies us that it is unwilling or unable to continue as depositary or
     if DTC ceases to be a clearing agency registered under applicable law and a
     successor depositary is not appointed by us within 90 days; or

     we determine not to require all of the notes of a series to be  represented
     by a global note and notify the Trustee of our decision.

Note Certificates-Registration, Transfer, and Payment of Interest and Principal

      If we issue note certificates,  they will be registered in the name of the
noteholder.   The  notes  may  be   transferred   or   exchanged,   pursuant  to
administrative  procedures in the indenture,  without the payment of any service
charge  (other  than any tax or other  governmental  charge) by  contacting  the
paying agent. Payments on note certificates will be made by check.

Interest Rate

      The  interest  rate on the notes  will  either be fixed or  floating.  The
interest  paid will  include  interest  accrued to, but  excluding,  the date of
maturity or  redemption.  Interest is  generally  payable to the person in whose
name the note is  registered  at the close of business on the record date before
each interest payment date. Interest payable at maturity or redemption, however,
will be payable to the person to whom principal is payable.

      If we  issue a note  after a record  date  but on or prior to the  related
interest  payment date, we will pay the first  interest  payment on the interest
payment date after the next record date. We will pay interest  payments by check
or wire transfer, at our option.

      Fixed Rate Notes

      A pricing or  prospectus  supplement  will  designate  the  record  dates,
payment  dates and the fixed rate of  interest  payable  on a note.  We will pay
interest quarterly or semi-annually,  and upon maturity or redemption. Unless an
applicable  pricing or prospectus  supplement states  otherwise,  if any payment
date falls on a day that is not a business day, we will pay interest on the next
business day and no additional  interest will be paid. Interest payments will be
the amount of interest  accrued to, but excluding,  each payment date.  Interest
will be computed using a 360-day year of twelve 30-day months.

      Floating Rate Notes

      Each floating rate note will have an interest rate formula. The applicable
pricing supplement will state the initial interest rate or interest rate formula
on each note  effective  until the first  interest  reset date.  The  applicable
pricing or  prospectus  supplement  will state the method and dates on which the
interest rate will be determined, reset and paid.



Events of Default

      "Event of Default" means any of the following:

       - failure to pay for three business days the principal of (or premium,
       if any, on) any note of a series when due and payable;

       - failure to pay for 30 days any interest on any note of any series when
       due and payable;

       - failure to perform  any other  requirements  in such  notes,  or in the
       Indenture in regard to such notes, for 90 days after notice;

       - certain events of bankruptcy or insolvency; or

       - any other event of default specified in a series of notes.

      An Event of Default for a particular  series of notes does not necessarily
mean that an Event of Default has  occurred for any other series of notes issued
under the Indenture. If an Event of Default occurs and continues, the Trustee or
the holders of at least 33% of the  principal  amount of the notes of the series
affected  may  require  us to repay the  entire  principal  of the notes of such
series immediately ("Repayment Acceleration"). In most instances, the holders of
at least a majority in aggregate  principal  amount of the notes of the affected
series may rescind a previously triggered Repayment Acceleration. However, if we
cause  an  Event  of  Default  because  we have  failed  to pay  (unaccelerated)
principal, premium, if any, or interest, Repayment Acceleration may be rescinded
only if we have first cured our default by  depositing  with the Trustee  enough
money to pay all (unaccelerated) past due amounts and penalties, if any.

      The Trustee must within 90 days after a default occurs, notify the holders
of the notes of the  series of default  unless  such  default  has been cured or
waived. We are required to file an annual  certificate with the Trustee,  signed
by an  officer,  concerning  any  default  by us  under  any  provisions  of the
Indenture.

      Subject to the provisions of the Indenture  relating to its duties in case
of default,  the Trustee  shall be under no  obligation  to exercise  any of its
rights or powers under the  Indenture at the request,  order or direction of any
holders unless such holders offer the Trustee reasonable  indemnity.  Subject to
the  provisions  for  indemnification,  the holders of a majority  in  principal
amount of the notes of any  series  may  direct  the time,  method  and place of
conducting any proceedings for any remedy  available to, or exercising any trust
or power conferred on, the Trustee with respect to such notes.

Modification of Indenture

      Under the  Indenture,  our  rights and  obligations  and the rights of the
holders  of any notes may be  changed.  Any change  affecting  the rights of the
holders of any series of notes  requires  the consent of the holders of not less
than a majority in aggregate  principal  amount of the outstanding  notes of all
series affected by the change,  voting as one class.  However,  we cannot change
the terms of payment of principal or interest,  or a reduction in the percentage
required for changes or a waiver of default,  unless the holder consents. We may
issue additional  series of notes and take other action that does not affect the
rights of holders of any series by executing supplemental indentures without the
consent of any noteholders.



Consolidation, Merger or Sale

      We may merge or consolidate with any corporation or sell substantially all
of our assets as an entirety as long as the  successor  or  purchaser  expressly
assumes the payment of  principal,  and  premium,  if any,  and  interest on the
notes.

Legal Defeasance

      We will be discharged  from our  obligations on the notes of any series at
any time if:

      - we deposit with the Trustee sufficient cash or government  securities to
      pay the  principal,  interest,  any  premium and any other sums due to the
      stated maturity date or a redemption date of the note of the series, and

      - we deliver to the Trustee an opinion of counsel stating that the federal
      income tax  obligations of noteholders of that series will not change as a
      result of our performing the action described above.

      If this happens, the noteholders of the series will not be entitled to the
benefits of the Indenture  except for  registration  of transfer and exchange of
notes and replacement of lost, stolen or mutilated notes.

Covenant Defeasance

      We will be discharged from our obligations under any restrictive  covenant
applicable  to the notes of a  particular  series  if we  perform  both  actions
described above. See Legal Defeasance. If this happens, any later breach of that
particular restrictive covenant will not result in Repayment Acceleration. If we
cause an Event of Default apart from breaching that restrictive covenant,  there
may not be  sufficient  money or  government  obligations  on  deposit  with the
Trustee to pay all amounts due on the notes of that series. In that instance, we
would remain liable for such amounts.

Governing Law

      The  Indenture and notes of all series will be governed by the laws of the
State of New York.

Concerning the Trustee

      We and our affiliates use or will use some of the banking  services of the
Trustee in the normal course of business.

                              PLAN OF DISTRIBUTION

      We may sell the notes (a)  through  agents;  (b) through  underwriters  or
dealers; or (c) directly to one or more purchasers.

By Agents

      Notes may be sold on a continuing  basis through agents  designated by us.
The agents will agree to use their reasonable  efforts to solicit  purchases for
the period of their appointment.

      Unless the pricing supplement states otherwise,  the notes will be sold to
the public at 100% of their principal  amount.  Agents will receive  commissions
from .125% to .750% of the principal  amount per note  depending on the maturity
of the note they sell.

      The Agents will not be obligated to make a market in the notes.  We cannot
predict the amount of trading or liquidity of the notes.



By Underwriters

      If underwriters  are used in the sale, the  underwriters  will acquire the
notes for their own  account.  The  underwriters  may resell the notes in one or
more transactions, including negotiated transactions, at a fixed public offering
price or at varying prices  determined at the time of sale.  The  obligations of
the  underwriters  to purchase the notes will be subject to certain  conditions.
The  underwriters  will be  obligated  to  purchase  all the notes of the series
offered if any of the notes are purchased. Any initial public offering price and
any  discounts or  concessions  allowed or  re-allowed or paid to dealers may be
changed from time to time.

Direct Sales

      We may also sell notes  directly.  In this case, no underwriters or agents
would be involved.

General Information

      Underwriters,  dealers, and agents that participate in the distribution of
the notes may be  underwriters  as  defined in the  Securities  Act of 1933 (the
"Act"), and any discounts or commissions received by them from us and any profit
on the resale of the notes by them may be treated as underwriting  discounts and
commissions under the Act.

      We may have  agreements  with the  underwriters,  dealers  and  agents  to
indemnify them against certain civil  liabilities,  including  liabilities under
the Act.

      Underwriters,  dealers  and  agents may engage in  transactions  with,  or
perform  services  for, us or our  affiliates  in the  ordinary  course of their
businesses.



                                 LEGAL OPINIONS

      Our  counsel,  Simpson  Thacher & Bartlett,  New York,  NY, and one of our
lawyers will each issue an opinion about the legality of the notes for us. Dewey
Ballantine  LLP,  New  York,  NY  will  issue  an  opinion  for  the  agents  or
underwriters.  From time to time,  Dewey  Ballantine  LLP acts as counsel to our
affiliates for some matters.

Item 15.  Indemnification of Directors and Officers.

      Section 23-1-37-8 of the Indiana Code provides that an Indiana corporation
may indemnify an individual made a party to a proceeding  because the individual
is or was a director if (i) the individual's conduct was in good faith, (ii) the
individual  reasonably believed that, in the case of conduct in the individual's
official  capacity  with the  corporation,  his or her  conduct  was in the best
interests of the corporation  and, in all other cases, his or her conduct was at
least not opposed to the best interests of the corporation and (iii) in the case
of a criminal  proceeding,  that the  director  either had  reasonable  cause to
believe his or her conduct was lawful or had no reasonable cause to believe that
such conduct was unlawful.  The termination of a proceeding by judgment,  order,
settlement,  conviction,  or upon a plea of nolo contendere or its equivalent is
not, of itself, determinative that a director did not meet the required standard
of conduct.  Section  23-1-37-9  requires a  corporation,  unless limited by its
articles  of  incorporation,  to  indemnify  a  director  who  has  been  wholly
successful in the defense of a proceeding against reasonable expenses (including
counsel fees) so incurred.  Section  23-1-37-10  authorizes a corporation to pay
for or reimburse the reasonable  expenses (including counsel fees) incurred by a
director  in  advance  of  final   disposition  of  a  proceeding  upon:  (1)  a
determination  that,  in light  of the  facts  then  known,  indemnification  is
permissible;  (2) receipt by the  corporation  of a written  affirmation  by the
director of his or her good faith belief that the  required  standard of conduct
has been met; and (3) receipt by the corporation of a written undertaking by the
director  to repay any such  advance  if it is  ultimately  determined  that the
director did not meet the required standard of conduct.

      Pursuant to Section  23-1-37-11,  a director may apply for indemnification
to a court of competent jurisdiction. Pursuant to Section 23-1-37-13, an officer
is entitled to mandatory  indemnification  under Section  23-1-37-9 and to apply
for court-ordered indemnification under Section 23-1-37-11 to the same extent as
a director.  A corporation  may  indemnify  and advance  expenses to an officer,
employee  or agent to the same  extent as to a  director.  Pursuant  to  Section
23-1-37-14, a corporation


may  purchase  and  maintain  insurance  on  behalf  of an  individual  who is a
director,  officer,  employee  or agent of the  corporation,  whether or not the
corporation would have power by statute to indemnify the individual  against the
same liability. Section 23-1-37-15 provides that the statutory provisions do not
exclude any other  rights to  indemnification  and advance for  expenses  that a
person  may  otherwise  have.  The  by-laws  of  the  Company  provide  for  the
indemnification of directors and officers of the Company
 to the full extent permitted by the Indiana Code.

      The above is a general  summary of  certain  provisions  of the  Company's
by-laws and of the Indiana  Code and is subject in all  respects to the specific
and detailed provisions of the Company's by-laws and the Indiana Code.

      Reference  is made to the  Underwriting  Agreement,  filed as Exhibit 1(b)
hereto, which provides for indemnification,  under certain circumstances, of the
Company,  certain of its  directors  and  officers,  and persons who control the
Company.

      The Company  maintains  insurance  policies  insuring  its  directors  and
officers against certain obligations that may be incurred by them.

Item 16.  Exhibits.

      Reference is made to the information  contained in the Exhibit Index filed
as a part of this Registration Statement.

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 or 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 unsecured  notes  offered (if the total dollar value
      of unsecured notes 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)  of the  Securities  Act  of  1933  if,  in the
      aggregate,  the changes in volume and price  represent  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  (i) and (ii) do not  apply if the  registration
statement  is on  Form  S-3 or Form  S-8,  and the  information  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 section 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 that 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  section  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 unsecured  notes offered,  and the
offering  thereof  at that  time  shall be deemed  to be the  initial  bona fide
offering thereof.

      (5)  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 laws of the State of  Indiana,  the
registrant's  by-laws or otherwise,  the registrant has been advised that in the
opinion of the  Commission  such  indemnification  is against  public  policy as
expressed  in said Act 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 unsecured  notes,  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 said Act and will
be governed by the final adjudication of such issue.

      (6) For purposes of determining  any liability under the Securities Act of
1933, the information  omitted from the form of prospectus filed as part of this
registration  statement  in reliance  upon Rule 430A and  contained in a form of
prospectus  filed by the registrant  pursuant to Rule 424(b)(1) or (4) or 497(h)
under  the  Securities  Act  shall  be  deemed  to be part of this  registration
statement as of the time it was declared effective.

      (7) For purposes of determining  any liability under the Securities Act of
1933, each post-effective  amendment that contains a form of prospectus 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.


                                   SIGNATURES

      Pursuant to the requirements of the Securities Act of 1933, the registrant
certifies  that it has  reasonable  cause to  believe  that it meets  all of the
requirements  for  filing  on Form S-3 and has  duly  caused  this  registration
statement  to be  signed  on its  behalf  by  the  undersigned,  thereunto  duly
authorized,  in the  City of  Columbus  and  State  of  Ohio,  on the 6th day of
