                                     PART I

 ITEM  1.  BUSINESS.

                                    GENERAL

         The registrant, Union Electric Company (the "Company"), incorporated in
 Missouri in 1922, is successor to a number of companies, the oldest of which
 was organized in 1881.  The Company, which is the largest electric utility in
 the State of Missouri, supplies electric service in territories in Missouri and
 Illinois having an estimated population of 2,600,000 within an area of
 approximately 24,500 square miles, including the greater St. Louis area.
 Natural gas purchased from non-affiliated pipeline companies is distributed in
 90 Missouri communities and in the City of Alton, Illinois and vicinity.

         For the year 1993, 95.2% of total operating revenues was derived from
 the sale of electric energy and 4.8% from the sale of natural gas.  Electric
 operating revenues as a percentage of total operating revenues for the years
 1989, 1990, 1991, and 1992 were 96%, 95.9%, 95.7%, and 95.7% respectively.

         The Company employed 6,417 persons at December 31, 1993.  Approximately
 70% of the Company's employees are represented by local unions affiliated with
 the AFL-CIO.  Labor agreements representing approximately 4,400 employees will
 expire in 1996.  One agreement covering 107 employees expires in 1994, and one
 agreement covering 21 employees will expire in 1997.



                       CONSTRUCTION PROGRAM AND FINANCING

         The Company is engaged in a construction program under which
 expenditures averaging approximately $310 million are anticipated during each
 of the next five years.  Capital expenditures for compliance with the Clean Air
 Act Amendments of 1990 are included in the construction program -- also see
 "Regulation", below.  The Company does not anticipate a need for additional
 electric generating capacity before the year 2000.

         During the five-year period ended 1993 gross additions to the property
 of the Company, including allowance for funds used during construction and
 excluding nuclear fuel, were approximately $1.2 billion (including $266 million
 in 1993) and property retirements were $190 million.

         In addition to the funds required for construction during the 1994-1998
 period, $174 million will be required to repay long-term debt and preferred
 stock as follows:  $31 million in 1994, $38 million in 1995, $60 million in
 1996, and $45 million in 1997.  Amounts for years subsequent to 1994 do not
 include nuclear fuel lease payments since the amounts of such payments are not
 currently determinable.

         For information on the Company's external cash sources, see "Liquidity
 and Capital Resources" under "Management's Discussion and Analysis" on Page 18
 of the 1993 Annual Report pages incorporated herein by reference.

                                      -1-

 
         Financing Restrictions.  Under the most restrictive earnings test
 contained in the Company's principal Indenture of Mortgage and Deed of Trust
 ("Mortgage") relating to its First Mortgage Bonds ("Bonds"), no Bonds may be
 issued (except in certain refunding operations) unless the Company's net
 earnings available for interest after depreciation for 12 consecutive months
 within the 15 months preceding such issuance are at least two times annual
 interest charges on all Bonds and prior lien bonds then outstanding and to be
 issued (all calculated as provided in the Mortgage).  Such ratio for the 12
 months ended December 31, 1993 was 6.3, which would permit the Company to issue
 an additional $2.9 billion of Bonds (7% annual interest rate assumed).
 Additionally, the Mortgage permits issuance of new bonds up to (a) 60% of
 defined property additions, or (b) the amount of previous bonds retired or to
 be retired, or (c) the amount of cash put up for such purpose.  At December 31,
 1993, the aggregate amount of Bonds issuable under (a) and (b) above was
 approximately $1.5 billion.  The Company's Articles of Incorporation restrict
 the Company from selling Preferred Stock unless its net earnings for a period
 of 12 consecutive months within 15 months preceding such sale are at least two
 and one-half times the annual dividend requirements on its Preferred Stock then
 outstanding and to be issued.  Such ratio for the 12 months ended December 31,
 1993 was 22.0, which would permit the Company to issue an additional $1.5
 billion stated value of Preferred Stock (7% annual dividend rate assumed).
 Certain other financing arrangements require the Company to obtain prior
 consents to various actions by the Company, including any future borrowings,
 except for permitted financings such as borrowings under revolving credit
 agreements, the nuclear fuel lease, unsecured short-term borrowings (subject to
 certain conditions), and the issuance of additional Bonds.


                                     RATES

         For the year 1993, approximately 89%, 8%, and 3% of the Company's
 electric operating revenues were based on rates regulated by Missouri Public
 Service Commission, Illinois Commerce Commission, and the Federal Energy
 Regulatory Commission ("FERC") of the Department of Energy, respectively.

         For additional information on rates, see the penultimate paragraph of
 Note 10 to the "Notes to Financial Statements" on Page 32 of the 1993 Annual
 Report pages incorporated herein by reference.

       Coal.  Because of uncertainties of supply due to potential work
 stoppages, equipment breakdowns and other factors, the Company has a policy of
 maintaining a coal inventory of 75 days, based on normal annual burn practices.
 See "Regulation" for additional reference to the Company's coal requirements.

                                      -2-

 
       Nuclear.  The components of the nuclear fuel cycle required for nuclear
 generating units are as follows:  (1) uranium; (2) conversion of uranium into
 uranium hexafluoride; (3) enrichment of uranium hexafluoride; (4) conversion of
 enriched uranium hexafluoride into uranium dioxide and the fabrication into
 nuclear fuel assemblies; and (5) disposal and/or reprocessing of spent nuclear
 fuel.

       The Company has contracts to fulfill its needs for uranium, enrichment,
 and fabrication services through 2002.  The Company's contract for conversion
 services is sufficient to supply the Callaway Plant through 1995.  Additional
 contracts will have to be entered into in order to supply nuclear fuel during
 the remainder of the estimated life of the Plant, at prices which cannot now be
 accurately predicted.  The Callaway Plant normally requires re-fueling at 18-
 month intervals and re-fuelings are presently scheduled for the spring of 1995
 and fall of 1996.

       Under the Nuclear Waste Policy Act of 1982, the U. S. Department of
 Energy (DOE) is responsible for the permanent storage and disposal of spent
 nuclear fuel.  DOE currently charges one mill per kilowatt-hour sold for future
 disposal of spent fuel.  Electric rates charged to customers provide for
 recovery of such costs.  DOE is not expected to have its permanent storage
 facility for spent fuel available until at least 2010.  The Company has
 sufficient storage capacity at the Callaway Plant site until 2004 and has
 viable storage alternatives under consideration that would provide additional
 storage facilities.  Each alternative will likely require Nuclear Regulatory
 Commission approval and may require other regulatory approvals. The delayed
 availability of DOE's disposal facility is not expected to adversely affect the
 continued operation of the Callaway Plant.

       Oil and Gas.  The actual and prospective use of such fuels is minimal,
 and the Company has not experienced and does not expect to experience
 difficulty in obtaining adequate supplies.



                                   REGULATION

       The Company is subject to regulation by the Missouri Commission and
 Illinois Commission as to rates, service, accounts, issuance of equity
 securities, issuance of debt having a maturity of more than twelve months, and
 various other matters.  The Company is also subject to regulation by the FERC
 as to rates and charges in connection with the transmission of electric energy
 in interstate commerce and the sale of such energy at wholesale in interstate
 commerce, and certain other matters.  Authorization to issue debt having a
 maturity of twelve months or less is obtained from the FERC.

       Operation of the Company's Callaway Plant is subject to regulation by the
 Nuclear Regulatory Commission.  The Company's Facility Operating License for
 the Callaway Plant expires on October 18, 2024.

       The Company's Osage hydroelectric plant and its Taum Sauk pumped-storage
 hydro plant, as licensed projects under the Federal Power Act, are subject to
 certain federal regulations affecting, among other things, the general
 operation and maintenance of the projects.  The Company's license for the Osage
 Plant expires on February 28, 2006, and its license for the Taum Sauk Plant
 expires on June 30, 2010.  The Company's Keokuk Plant and dam located in the
 Mississippi River between Hamilton, Illinois and Keokuk, Iowa, are operated
 under authority, unlimited in time, granted by an Act of Congress in 1905.

                                      -3-

 
       The Company is exempt from the provisions of the Public Utility Holding
 Company Act of 1935, except Section 9(a)(2) relating to the acquisition of
 securities of other public utility companies and Section 11(b)(2) with respect
 to concluding matters relating to the 1974 acquisition of the common stock of a
 former subsidiary.  When the Securities and Exchange Commission approved such
 acquisition it reserved jurisdiction to pass upon the right of the Company to
 retain its gas properties.

       The Company is regulated, in certain of its operations, by air and water
 pollution and hazardous waste regulations at the city, county, state and
 federal levels.  The Company is in substantial compliance with such existing
 regulations.

       Under the Clean Air Act Amendments of 1990, the Company is required to
 reduce total annual emissions of sulfur dioxide by approximately two-thirds by
 the year 2000.  Significant reductions in nitrogen oxide will also be required.
 With switching to low-sulfur coal and early banking of emission credits, the
 Company anticipates that it can comply with the requirements of the law with no
 significant increase in revenue needs because the related capital costs,
 currently estimated at about $300 million, will be largely offset by lower fuel
 costs.  The Company's Clean Air Act compliance program is subject to approval
 by regulatory authorities.

       As of December 31, 1993, the Company was designated a potentially
 responsible party (PRP) by federal and state environmental protection agencies
 for five hazardous waste sites.  Other hazardous waste sites have been
 identified for which the Company may be responsible but has not been designated
 a PRP.  The Company is presently investigating the remedial costs that will be
 required for all of these sites.  Such costs are not expected to have a
 material adverse effect on the Company's financial position.

       Other aspects of the Company's business are subject to the jurisdiction
 of various regulatory authorities.



                                INDUSTRY ISSUES

       The Company is facing issues common to the electric and gas utility
 industries which have emerged during the past several years.  These issues
 include:  changes in the structure of the industry as a result of amendments to
 federal laws regulating ownership of generating facilities and access to
 transmission systems; continually developing environmental laws, regulations
 and issues; public concern about the siting of new facilities; increasing
 public attention on the potential public health consequences of exposure to
 electric and magnetic fields emanating from power lines and other electric
 sources; proposals for demand side management programs; and public concerns
 about the disposal of nuclear wastes and about global climate issues.  The
 Company is monitoring these issues and is unable to predict at this time what
 impact, if any, these issues will have on its operations or financial
 condition.

       In planning its construction program, the Company is presently utilizing
 a forecast of kilowatthour sales growth of approximately 1.8% and peak load
 growth of 1.0%, each compounded annually, and is providing for a minimum
 reserve margin of approximately 18% to 20% above its anticipated peak load
 requirements.

       See "Operating Statistics", incorporated by reference in Part I of this
 Form 10-K, for information on loads and capability during the five-year period
 ended 1993.

       See "Liquidity and Capital Resources" under "Management's Discussion and
 Analysis" on Pages 17 and 18 of the 1993 Annual Report pages incorporated
 herein by reference for information on the 1992 purchase and sale of certain
 properties.

       The Company is a member of one of the nine regional electric reliability
 councils organized for coordinating the planning and operation of the nation's
 bulk power supply - MAIN (Mid-America Interconnected Network) operating
 primarily in Wisconsin, Illinois and Missouri.  The Company has
 interconnections for the exchange of power, directly and through the facilities
 of

                                      -6-

 
 others, with fifteen private utilities and with Associated Electric
 Cooperative, Inc., the City of Columbia, Missouri, the Southwestern Power
 Administration and the Tennessee Valley Authority.

       The Company owns 40% of the capital stock of Electric Energy, Inc.
 ("EEI"), the balance of which is held by three other sponsoring companies --
 Kentucky Utilities Company ("KU"), Central Illinois Public Service ("CIPS"),
 and Illinois Power Company ("IP").  EEI owns and operates a generating plant
 with a nominal capacity of 1,000 mW.  As of January 1, 1994, 60% of the plant's
 output is committed to the Paducah Project of the DOE, 20% is committed to KU,
 10% to the Company, and 5% each to IP and CIPS.

       As of December 31, 1993, the Company owned approximately 3,297 circuit
 miles of electric transmission lines and 731 substations with a transformer
 capacity of approximately 44,324,000 kVA.  The Company owns four propane-air
 plants with an aggregate daily natural gas equivalent capacity of 31,590
 million cubic feet and 2,599 miles of gas mains.  Other properties of the
 Company include distribution lines, underground cable, steam distribution
 facilities in Jefferson City, Missouri and office buildings, warehouses,
 garages and repair shops.

       The Company has fee title to all principal plants and other important
 units of property, or to the real property on which such facilities are located
 (subject to mortgage liens securing outstanding indebtedness of the Company and
 to permitted liens and judgment liens, as defined), except that (i) a portion
 of the Osage Plant reservoir, certain facilities at the Sioux Plant, certain of
 the Company's substations and most of its transmission and distribution lines
 and gas mains are situated on lands occupied under leases, easements,
 franchises, licenses or permits; (ii) the United States and/or the State of
 Missouri own, or have or may have, paramount rights to certain lands lying in
 the bed of the Osage River or located between the inner and outer harbor lines
 of the Mississippi River, on which certain generating and other properties of
 the Company are located; and (iii) the United States and/or State of Illinois
 and/or State of Iowa and/or City of Keokuk, Iowa own, or have or may have,
 paramount rights with respect to, certain lands lying in the bed of the
 Mississippi River on which a portion of the Company's Keokuk Plant is located.

       Substantially all of the Company's property and plant is subject to the
 direct first lien of an Indenture of Mortgage and Deed of Trust dated June 15,
 1937, as amended and supplemented.  As part of the 1983 merger of the Company
 with its utility subsidiaries, the Company assumed the mortgage indenture of
 each subsidiary.  Currently, the prior liens of two former subsidiary
 indentures extend to the property and franchises acquired by the Company from
 such subsidiaries.  Such indentures also contain provisions subjecting to the
 prior lien thereof after-acquired property of the Company constituting (with
 certain exceptions) additions, extensions, improvements, repairs, and
 replacements appurtenant to property acquired in the merger.  In addition, one
 such indenture contains a provision subjecting to the prior lien thereof after-
 acquired property of the Company situated in the territory served by the former
 subsidiary prior to the merger.


 ITEM   3.  LEGAL PROCEEDINGS.

     The Company is involved in legal and administrative proceedings before
 various courts and agencies with respect to matters arising in the ordinary
 course of business, some of which involve substantial amounts.  Management is
 of the opinion that the final disposition of these proceedings will not have a
 material adverse effect on the Company's financial position.

         Our audits of the financial statements referred to in our report dated
         February 2, 1994 appearing on page 19 of the 1993 Annual Report to
         Stockholders of Union Electric Company (which report and financial
         statements are incorporated by reference in this Annual Report on Form
         10-K) also included an audit of the Financial Statement Schedules
         listed in Item 14(a) of this Form 10-K.  In our opinion, these
         Financial Statement Schedules present fairly, in all material respects,
         the information set forth therein when read in conjunction with the
         related financial statements.
