        When this prospectus supplement uses the words "SCE&G," "we," "us," and "our," they refer to South Carolina Electric & Gas Company, unless otherwise expressly stated or the context otherwise requires. The term "Company," when used in this prospectus supplement, means us and our consolidated affiliates, unless otherwise expressly stated or the context otherwise requires.

        You should rely only on the information contained or incorporated by reference in this prospectus supplement and the accompanying prospectus and in any written communication from us specifying the final terms of the offering. To the extent the information in this prospectus supplement differs from the information in the accompanying prospectus, you should rely on the information in this prospectus supplement. Neither we nor the underwriters have authorized anyone to provide you with different information. If anyone provides you with different or inconsistent information, you should not rely on it. Neither we nor the underwriters are making an offer of these securities in any jurisdiction where the offer is not permitted. The information in this prospectus supplement, the accompanying prospectus, the documents incorporated by reference and any written communication from us specifying the final terms of the offering is only accurate as of the date of the respective documents in which the information appears. Our business, financial condition, results of operations and prospects may have changed since those dates.

WHERE YOU CAN FIND MORE INFORMATION

        We file annual, quarterly and current reports and other information with the SEC under the Exchange Act. Our SEC filings are available to the public over the Internet at the SEC's web site at http://www.sec.gov. You may also read and copy any document we file with the SEC at the public reference room at 100 F Street, N.E., Washington, D.C. 20549. Please call the SEC at 1-800-SEC-0330 for further information on the operation of the public reference rooms.

        This prospectus supplement does not repeat important information that you can find in our registration statement (File No. 333-184426-01) and in the reports and other documents which we file with the SEC under the Exchange Act. The SEC allows us to "incorporate by reference" the information we file with it, which means that we can disclose important information to you by referring you to those documents. The information incorporated by reference is an important part of this prospectus supplement and the accompanying prospectus, and information that we file later with the SEC will automatically update and supersede some of this information. We incorporate by reference our Annual Report on Form 10-K for the year ended December 31, 2012; our Quarterly Report on Form 10-Q for the quarter ended March 31, 2013; and our Current Reports on Form 8-K, filed January 11, 2013 and June 5, 2013; and any future filings (other than information in such documents that is deemed not to be filed) made with the SEC under Sections 13(a), 13(c), 14, or 15(d) of the Exchange Act until we sell all of the Bonds.

        We and our parent company, SCANA, separately filed on a combined basis the Annual Report on Form 10-K, the Quarterly Report on Form 10-Q and the Current Reports on Form 8-K filed on January 11, 2013 and June 5, 2013. However, the information contained in the combined reports relating solely to SCANA and its subsidiaries (other than the information in the reports filed by and relating to SCE&G and its consolidated affiliates) was separately filed by SCANA, and the information contained in the combined reports filed by and relating to SCE&G and its consolidated affiliates was separately filed by us. The only information you should rely upon in determining whether to invest in the securities offered hereby is the information relating to SCE&G and its consolidated affiliates contained in this prospectus supplement and the accompanying prospectus, the information separately filed by SCE&G and its consolidated affiliates in the documents incorporated by reference herein and any free writing prospectus used in connection with the offering of Bonds described in this prospectus supplement.

        We are not required to, and do not, provide annual reports to holders of our debt securities unless specifically requested by a holder.

        You may request a copy of our SEC filings at no cost by writing or telephoning us at the following address or phone number, as the case may be:

        You may obtain more information by visiting SCANA's Internet web site at http://www.scana.com (which is not intended to be an active hyperlink).

RECENT DEVELOPMENTS

        The consortium which is constructing our two new nuclear generation units has experienced delays in the schedule for fabrication and delivery of sub-modules for the new units. Following an examination of this issue, the consortium has preliminarily indicated that the substantial completion of the first unit is expected to be delayed until late 2017 or the first quarter of 2018 and that the substantial completion of the second new unit is expected to be similarly delayed.

        The substantial completion dates currently approved by the South Carolina Public Service Commission ("SCPSC") for the first and second new units are March 15, 2017 and May 15, 2018, respectively. The SCPSC has also approved an 18-month contingency period beyond each of these dates. As indicated above, the preliminary expected new substantial completion dates are within the contingency periods.

        We cannot predict with certainty the extent to which the issue with the sub-modules or the delays in the substantial completion of the new units will result in increased project costs. However, our preliminary estimate of the delay-related costs associated with our share of the new units is approximately $200 million. We intend to continue to work with the consortium to refine this preliminary estimate and we expect to have further discussions with them regarding responsibility for these increased costs.

USE OF PROCEEDS

        We expect to apply the net proceeds from the sale of this offering of the Bonds to pay at maturity $150 million of our First Mortgage Bonds due June 15, 2013 (which bear interest at the fixed per annum rate of 71/8%), to repay short-term debt primarily incurred as a result of our construction program, to finance capital expenditures (including costs to construct new nuclear units at our V.C. Summer Nuclear Station) and for general corporate purposes. As of May 31, 2013, SCE&G had approximately $154.5 million of short-term debt outstanding due upon demand or having maturities of one year or less and having (as of the most recent dates of determination) interest rates ranging from 0.29% to 0.32% per annum.

RATIO OF EARNINGS TO FIXED CHARGES

        Our historical ratios of earnings to fixed charges are as follows:

Three Months
Ended
March 31,
2013
  Twelve Months
Ended
March 31,
2013
  Year Ended December 31,  
  2012   2011   2010   2009   2008  
3.38     3.38     3.29     3.13     3.18     3.25     3.51  
                           

        For purposes of this ratio, earnings represent pre-tax income from continuing operations plus fixed charges and distributed income from equity investees, less preferred stock dividend requirements. Fixed charges represent interest charges, preferred security dividend requirements and the estimated interest portion of annual rentals.

TERMS OF THE BONDS

        We will issue the Bonds under the Indenture dated as of April 1, 1993, as supplemented (the "Mortgage"), made between us and The Bank of New York Mellon Trust Company, N.A., successor to NationsBank of Georgia, National Association, as trustee (the "Trustee"). The Bonds will initially be limited to $                      in aggregate principal amount.

        We may, without the consent of the existing holders of the Bonds, "reopen" the series of Bonds offered hereby and issue additional bonds under the Mortgage having the same ranking and the same

S-4


Table of Contents

interest rate, maturity and other terms as the Bonds (except for the price to public). Any additional bonds having similar terms, together with the Bonds, will constitute a single series of securities under the Mortgage. The following information concerning the Bonds supplements and should be read in conjunction with the statements under "DESCRIPTION OF THE FIRST MORTGAGE BONDS" in the accompanying prospectus.

Form

        The Bonds will be issued as one or more global certificates in the name of Cede & Co., as nominee for The Depository Trust Company ("DTC"), New York, New York, and will be available only in book-entry form. See "—Book-Entry System" herein.

Interest and Maturity

        We will pay interest on the Bonds from                            , at the rate of          % per year (based upon a 360-day year of twelve 30-day months), semiannually in arrears on                  and                of each year commencing on                          to holders of record on the preceding                   and                respectively. The Bonds will mature                            . The principal and interest are payable at the office or agency of SCE&G in Atlanta, Georgia (currently, the Trustee is designated as such office or agency).

Optional Redemption

        The Bonds are redeemable, in whole or in part, at any time and from time to time on and after                            , at our option, at a redemption price equal to 100% of the principal amount of the Bonds being redeemed, plus accrued and unpaid interest thereon to the redemption date.

        In addition, the Bonds are redeemable, in whole or in part, at any time and from time to time prior to                            , at our option, at a redemption price equal to the greater of:

        plus, in either of the above cases, accrued and unpaid interest thereon to the redemption date.

        "Adjusted Treasury Rate" means, with respect to any redemption date:

S-5


Table of Contents

        The Adjusted Treasury Rate shall be calculated on the third business day preceding the redemption date.

        "Comparable Treasury Issue" means the United States Treasury security selected by an Independent Investment Banker as having a maturity comparable to the remaining term of the Bonds to be redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of those Bonds (the "Remaining Life").

        "Comparable Treasury Price" means (1) the average of five Reference Treasury Dealer Quotations for the redemption date, after excluding the highest and lowest Reference Treasury Dealer Quotations, or (2) if the Independent Investment Banker obtains fewer than five Reference Treasury Dealer Quotations, the average of all such quotations.

        "Independent Investment Banker" means one of Merrill Lynch, Pierce, Fenner & Smith Incorporated, Morgan Stanley & Co. LLC, UBS Securities LLC or Mizuho Securities USA Inc. and their respective successors, as selected by us, or if none of such firms is willing or able to serve as such, another primary United States government securities dealer in the United States (a "Primary Treasury Dealer") appointed by us.

        "Reference Treasury Dealer" means each of Merrill Lynch, Pierce, Fenner & Smith Incorporated, Morgan Stanley & Co. LLC, UBS Securities LLC, Mizuho Securities USA Inc. and one other Primary Treasury Dealer selected by TD Securities (USA) LLC and their respective successors; provided that, if any such firm or its successor ceases to be a Primary Treasury Dealer, we shall substitute another Primary Treasury Dealer.

        "Reference Treasury Dealer Quotations" means, with respect to each Reference Treasury Dealer and any redemption date, the average, as determined by the Independent Investment Banker, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Independent Investment Banker at 5:00 p.m., New York City time, on the third business day preceding such redemption date.

        Unless we default in payment of the redemption price, interest will cease to accrue on and after the redemption date on the Bonds or portions thereof called for redemption.

Book-Entry System

        The following information concerning DTC and its book-entry system has been obtained from sources that we believe to be reliable, but neither we nor any underwriter take any responsibility for the accuracy of that information. The following language supplements the information contained under the heading "BOOK-ENTRY SYSTEM" in the accompanying prospectus.

        DTC will act as securities depository for the Bonds. The Bonds will be issued initially as fully-registered securities registered in the name of Cede & Co. (DTC's partnership nominee), or such other name as may be requested by an authorized representative of DTC. One fully-registered certificate will be issued for the Bonds in the aggregate principal amount of such issue, and will be deposited with DTC. If, however, the aggregate principal amount of the Bonds exceeds $500 million, one certificate will be issued with respect to each $500 million of principal amount, and an additional certificate will be issued with respect to any remaining principal amount of the Bonds.

        DTC, the world's largest depository, 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

S-6


Table of Contents

Commercial Code, and a "clearing agency" registered pursuant to the provisions of Section 17A of the Exchange Act. DTC holds and provides asset servicing for over 3.5 million issues of U.S. and non-U.S. equity issues, corporate and municipal debt issues, and money market instruments (from over 100 countries) that DTC's participants ("Direct Participants") deposit with DTC. DTC also facilitates the post-trade settlement among Direct Participants of sales and other securities transactions in deposited securities, through electronic computerized book-entry transfers and pledges between Direct Participants' accounts. This eliminates the need for physical movement of securities certificates. Direct Participants include both U.S. and non-U.S. securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations. DTC is a wholly-owned subsidiary of The Depository Trust & Clearing Corporation ("DTCC"). DTCC is the holding company for DTC, National Securities Clearing Corporation and Fixed Income Clearing Corporation, all of which are registered clearing agencies. DTCC is owned by the users of its regulated subsidiaries. Access to the DTC system is also available to others such as both U.S. and non-U.S. securities brokers and dealers, banks, trust companies, and clearing corporations that clear through or maintain a custodial relationship with a Direct Participant, either directly or indirectly ("Indirect Participants" and, together with the Direct Participants, "DTC Participants"). The DTC rules applicable to DTC's Participants are on file with the SEC.

        Purchases of Bonds under the DTC system must be made by or through Direct Participants, which will receive a credit for the Bonds on DTC's records. The ownership interest of each actual purchaser of each Bond ("Beneficial Owner") is in turn to be recorded on the Direct and Indirect Participants' records. Beneficial Owners will not receive written confirmation from DTC of their purchases. Beneficial Owners are, however, expected to receive written confirmation from DTC 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 beneficial ownership interests in the Bonds 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 the Bonds, unless the use of the book-entry only system for the Bonds is discontinued.

        To facilitate subsequent transfers, all Bonds deposited by Direct Participants with DTC are registered in the name of DTC's partnership nominee, Cede & Co., or such other name as may be requested by an authorized representative of DTC. The deposit of the Bonds with DTC and their registration in the name of Cede & Co. or such other DTC nominee do not effect any change in beneficial ownership. DTC has no knowledge of the actual Beneficial Owners of the Bonds; DTC's records reflect only the identity of the Direct Participants to whose accounts such Bonds 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 DTC 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. Beneficial Owners of Bonds may wish to take certain steps to augment the transmission to them of notices of significant events with respect to the Bonds, such as redemptions, tenders, defaults, and proposed amendments to the Bond documents. For example, Beneficial Owners of Bonds may wish to ascertain that the nominee holding the Bonds for their benefit has agreed to obtain and transmit notices to Beneficial Owners.

        In the alternative, Beneficial Owners may wish to provide their names and addresses to the Trustee and request that copies of notices be provided directly to them.

        Redemption notices will be sent to DTC. If less than all of the Bonds are being redeemed, DTC's practice is to determine by lot the amount of the interest of each Direct Participant to be redeemed.

        Neither DTC nor Cede & Co. (nor such other DTC nominee) will consent or vote with respect to Bonds unless authorized by a Direct Participant in accordance with DTC's MMI procedures. Under its

S-7


Table of Contents

usual procedures, DTC 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 Bonds are credited on the record date (identified in a listing attached to the Omnibus Proxy).

        Payments of principal, interest and redemption premium, if any, on the Bonds will be made to Cede & Co., or such other nominee as may be requested by an authorized representative of DTC. DTC's practice is to credit Direct Participants' accounts upon DTC's receipt of funds and corresponding detail information from us or the Trustee on the payable date in accordance with their respective holdings shown on DTC's records. Payments by DTC 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 DTC Participant and not of DTC, the Trustee or us, subject to any statutory or regulatory requirements as may be in effect from time to time. Payment of principal, premium, if any, and interest to Cede & Co. (or such other nominee as may be requested by an authorized representative of DTC) is the responsibility of us or the Trustee, disbursement of such payments to Direct Participants is DTC's responsibility, and disbursement of such payments to the Beneficial Owners shall be the responsibility of Direct and Indirect Participants.

        DTC may discontinue providing its services as depository with respect to the Bonds by giving reasonable notice to us or the Trustee. Under such circumstances, in the event a successor depository is not obtained, Bond certificates are required to be printed and delivered.

        We may decide to discontinue use of the book-entry only system through DTC (or a successor depository). In that event, Bond certificates will be printed and delivered to DTC.

BASIS FOR ISSUANCE OF THE BONDS

        We will issue the Bonds upon the basis of property additions certified to the Trustee and designated by us as the basis for such issuance. See "DESCRIPTION OF THE FIRST MORTGAGE BONDS" in the accompanying prospectus. Based upon property additions expected to be certified to the Trustee as of the date of delivery of the Bonds, we will have unfunded net property additions of approximately $3.7 billion, sufficient to permit the issuance of approximately $2.6 billion of additional bonds on the basis thereof (including $                      of the Bonds offered hereby). At May 31, 2013, we had approximately $341 million of credits from the retirement of bonds under the Mortgage, which may be used as the basis for the authentication of additional bonds under the Mortgage.

UNDERWRITING

        Under the terms and subject to the conditions contained in an underwriting agreement, dated June     , 2013, the underwriters named below have severally agreed to purchase, and we have agreed to sell to them, severally, the respective principal amount of Bonds set forth opposite their names below:

Underwriter
  Principal Amount
of Bonds
 

Merrill Lynch, Pierce, Fenner & Smith
                      Incorporated

       

Morgan Stanley & Co. LLC

       

UBS Securities LLC

       

Mizuho Securities USA Inc. 

       

TD Securities (USA) LLC

       

BB&T Capital Markets,

Mitsubishi UFJ Securities (USA), Inc. 

       

Synovus Securities, Inc. 

       
       

Total

       
       

        The underwriting agreement provides that the obligations of the underwriters to pay for and accept delivery of the Bonds are subject to, among other things, the approval of certain legal matters by their counsel and certain other conditions. The underwriters are obligated to take and pay for all of the Bonds if any are taken.

        The underwriters initially propose to offer part of the Bonds directly to the public at the public offering price set forth on the cover page of this prospectus supplement and part of the Bonds to certain dealers at a price that represents a concession not in excess of          % of the principal amount of the Bonds. Any underwriter may allow, and any such dealers may reallow, a concession to certain other dealers not to exceed          % of the principal amount of the Bonds. After the initial offering of the Bonds, the offering price and other selling terms may be changed by the underwriters.

        We have agreed to indemnify the underwriters against certain liabilities, including liabilities under the Securities Act, and to contribute to payments the underwriters may be required to make in respect of any of these liabilities.

        We estimate that our total expenses relating to the offering, not including the underwriting discount, will be approximately $720,000.

        We do not intend to apply for listing of the Bonds on a national securities exchange or for their inclusion in any automated quotation system, but have been advised by the underwriters that they intend to make a market in the Bonds. The underwriters are not obligated, however, to do so and may discontinue their market making at any time without notice. No assurance can be given as to the liquidity or development of the trading market for the Bonds.

        In order to facilitate the offering of the Bonds, the underwriters may engage in transactions that stabilize, maintain or otherwise affect the price of the Bonds. Specifically, the underwriters may overallot in connection with the offering, creating a short position in the Bonds for their own account. In addition, to cover overallotments or to stabilize the price of the Bonds, the underwriters may bid for, and purchase, the Bonds in the open market. Finally, the underwriters may reclaim selling concessions allowed to an underwriter or a dealer for distributing the Bonds in the offering, if they repurchase previously distributed Bonds in transactions to cover syndicate short positions, in stabilization transactions or otherwise. Any of these activities may stabilize or maintain the market price for the Bonds above independent market levels. The underwriters are not required to engage in these activities and may end any of these activities at any time without notice.

        We expect that delivery of the Bonds will be made against payment therefor on or about                            which will be the fourth business day following the date hereof (this settlement date being referred to as "T+4"). Under Rule 15c6-1 of the SEC under the Exchange Act, trades in the secondary market generally are required to settle in three business days, unless the parties to that trade expressly agree to otherwise. Accordingly, purchasers who wish to trade Bonds on the date hereof will be required, by virtue of the fact that the Bonds initially will settle in T+4, to specify an alternate settlement cycle at the time of any such trade to prevent a failed settlement and should consult their own advisors.

        The underwriters and their respective affiliates are full service financial institutions engaged in various activities, which may include securities trading, commercial and investment banking, financial advisory, investment management, investment research, principal investment, hedging, financing and brokerage activities. Certain of the underwriters and their respective affiliates have, from time to time, performed, and may in the future perform, various commercial banking, investment banking and advisory services for us, for which they received or will receive customary fees and expenses.

        In addition, in the ordinary course of their business activities, the underwriters and their affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers. Such investments and securities activities may involve securities and/or instruments of ours or our affiliates. Certain of the underwriters or their affiliates that have a lending relationship with us routinely hedge their credit exposure to us consistent with their customary risk management policies. Typically, such underwriters and their affiliates would hedge such exposure by entering into transactions which consist of either the purchase of credit default swaps or the creation of short positions in our securities, including potentially the Bonds offered hereby. Any such credit default swaps or short positions could adversely affect future trading prices of the Bonds offered hereby. The underwriters and their affiliates may also make investment recommendations and/or publish or express independent research views in respect of such securities or financial instruments and may hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments.

Conflicts of Interest

        As described in "Use of Proceeds" on page S-4, a portion of the net proceeds of this offering may be used to repay short-term debt primarily incurred as a result of our construction program. In addition, certain of the underwriters or their affiliates are counterparties with respect to interest rate hedges entered into by SCE&G in anticipation of the issuance of the Bonds which will be settled at or about the time of issuance of the Bonds. If more than 5% of the net proceeds of this offering, not including underwriting compensation, will be received by affiliates of any underwriter in this offering, the offering will be conducted in compliance with FINRA Rule 5121, as administered by the Financial Industry Regulatory Authority. Pursuant to that rule, the appointment of a qualified independent underwriter is not necessary in connection with this offering.

LEGAL MATTERS

        Certain legal matters in connection with the offering of the Bonds will be passed on for SCE&G by McNair Law Firm, P.A., of Columbia, South Carolina, and Ronald T. Lindsay, Esq., our Senior Vice President and General Counsel, and for the underwriters by Troutman Sanders LLP, of Richmond, Virginia, which also performs other legal services for us. Troutman Sanders LLP will rely as to all matters of South Carolina law upon the opinion of Ronald T. Lindsay, Esq.

        At May 31, 2013, Ronald T. Lindsay, Esq., owned beneficially 1,976 shares of SCANA's Common Stock, including shares acquired by the trustee under SCANA's Stock Purchase-Savings Program by use of contributions made by Mr. Lindsay and earnings thereon and including shares purchased by that trustee by use of SCANA contributions and earnings thereon.

EXPERTS

        The consolidated financial statements and the related financial statement schedule, incorporated in this prospectus supplement and the related prospectus by reference from SCE&G's Annual Report on Form 10-K for the year ended December 31, 2012, have been audited by Deloitte & Touche LLP, an independent registered public accounting firm, as stated in their report, which is incorporated herein by reference.

THE REGISTRANTS

        SCANA is an energy-based holding company which, through its subsidiaries, engages principally in electric and natural gas utility operations and other energy-related businesses. Through its subsidiaries, the Company serves more than 664,000 electric customers in South Carolina and more than 1.2 million natural gas customers in South Carolina, North Carolina and Georgia.

        SCANA is a South Carolina corporation with general business powers, and was incorporated on October 10, 1984. SCANA's principal executive office is located at 100 SCANA Parkway, Cayce, South Carolina 29033, telephone (803) 217-9000, and its mailing address is 220 Operation Way, Cayce, South Carolina 29033-3701.

        The Company operates its regulated utility businesses in North Carolina and South Carolina through wholly-owned subsidiaries. These regulated businesses continue to be the foundation of the Company's operations and are conducted in an environment supported by growing service territories and favorable regulatory treatment. The Company is allowed, subject to state commission approval during annual fuel and purchased gas cost hearings, full pass-through to retail customers of its electric fuel and natural gas costs. This approval has historically been granted. There is also a weather normalization clause in effect for our electric customers and for our natural gas customers in South Carolina. In North Carolina, Public Service Company of North Carolina, Incorporated ("PSNC Energy") utilizes a customer usage tracker ("CUT"), a rate decoupling mechanism that breaks the link between revenues and the amount of natural gas sold, which allows PSNC Energy to periodically adjust its base rates for residential and commercial customers based on average per customer consumption. These measures mitigate our commodity price risk and customer usage fluctuations and allow us to focus our efforts on serving our customers. The following is a discussion of the Company's principal regulated utility subsidiaries.

        SCE&G.    SCE&G is a public utility engaged in the generation, transmission, distribution and sale of electricity and the purchase, sale and transportation of natural gas in South Carolina. SCE&G's electric service area extends into 24 counties covering more than 17,000 square miles of the central, southern and southwestern portions of South Carolina. SCE&G's service area for natural gas encompasses more than 22,600 square miles in all or part of 35 of South Carolina's 46 counties. The total population of the counties representing SCE&G's combined service area is more than 3.2 million. SCE&G's principal executive office is located at 100 SCANA Parkway, Cayce, South Carolina 29033, telephone (803) 217-9000, and its mailing address is 220 Operation Way, Cayce, South Carolina 29033-3701.

        SCE&G provides all of its electric generation capacity through its own facilities and through the purchase of all of the electric generation of Williams Station, which is owned by South Carolina Generating Company, Inc. ("GENCO"), a wholly owned subsidiary of SCANA.

        SCE&G also operates and has a two-thirds interest in V. C. Summer Nuclear Station in South Carolina. This station furnished approximately 19% of SCE&G's electric generating capacity in 2011.

        SCE&G is a party to construction and operating agreements in which it agreed to be joint owner, and share operating costs and generation output, of two 1,117-MW nuclear generation units to be constructed at the site of Summer Station, with SCE&G responsible for 55 percent of the cost and receiving 55 percent of the output. Under these agreements, SCE&G has the primary responsibility for oversight of the construction of the two new nuclear generation units and will be responsible for their operation as they come online. SCE&G's share of the estimated cash outlays (future value, excluding allowance for funds used during construction) totals approximately $6 billion for plant costs and related transmission infrastructure costs, which costs are projected based on historical one-year and five-year

escalating rates as required by the Public Service Commission of South Carolina. The first of the two new nuclear generation units is scheduled for substantial completion in 2017, and the second new unit is scheduled for substantial completion in 2018.

        PSNC Energy.    PSNC Energy is a public utility engaged primarily in purchasing, selling and transporting natural gas to approximately 487,000 residential, commercial and industrial customers in North Carolina. PSNC Energy's franchised service area includes 28 counties covering approximately 12,000 square miles of North Carolina.

        PSNC Energy is regulated by the North Carolina Utilities Commission ("NCUC"). PSNC Energy's rates are established using a benchmark cost of gas approved by the NCUC, which may be modified periodically to reflect changes in the market price of natural gas and, through operation of the CUT, PSNC Energy's base rates for residential and commercial customers are also adjusted based on average per customer consumption. The NCUC reviews PSNC Energy's gas purchasing practices each year.

        Carolina Gas Transmission Corporation ("CGT").    CGT operates as an open access, transportation-only interstate pipeline company and is regulated by the Federal Energy Regulatory Commission.

        CGT transports natural gas in southeastern Georgia and in South Carolina and has interconnections with Southern Natural Gas Company ("Southern Natural") at Port Wentworth, Georgia and with Southern LNG, Inc. at Elba Island, near Savannah, Georgia. CGT also has interconnections with Southern Natural in Aiken County, South Carolina, and with Transcontinental Gas Pipeline Corporation in Cherokee and Spartanburg counties, South Carolina. CGT's customers include SCE&G (which uses natural gas for electricity generation and for gas distribution to retail customers), SCANA Energy Marketing, Inc. (which markets natural gas to industrial and sale for resale customers, primarily in the Southeast), municipalities, county gas authorities, federal and state agencies, marketers, power generators and industrial customers primarily engaged in the manufacturing or processing of ceramics, paper, metal, and textiles.

        SCANA Energy Marketing, Inc.    SCANA Energy Marketing, Inc. markets natural gas primarily in the southeastern United States, and provides energy-related risk management services to producers and customers. SCANA Energy, a division of SCANA Energy Marketing, Inc., markets natural gas in Georgia's deregulated natural gas market. At June 30, 2012, SCANA Energy had approximately 450,000 natural gas customers in the Georgia market and serves as Georgia's regulated provider under a contract with the Georgia Public Service Commission. SCANA Energy is the second-largest marketer in Georgia's non-regulated retail gas market. SCANA Energy faces significant competition in the Georgia natural gas market.

        The information above concerning us and our subsidiaries is only a summary and does not purport to be comprehensive. For additional information concerning us and our subsidiaries, you should refer to the information described in "WHERE YOU CAN FIND MORE INFORMATION."

DESCRIPTION OF THE MEDIUM TERM NOTES

General

        SCANA will issue the Notes under an Indenture dated as of November 1, 1989, as amended by the First Supplemental Indenture dated as of November 1, 2009 (as so amended, the "Note Indenture"), between SCANA and The Bank of New York Mellon Trust Company, N. A. (successor to The Bank of New York), as trustee (the "Note Trustee"). A copy of the Note Indenture has been incorporated by reference as an exhibit to the registration statement of which this prospectus is a part. The information in this section "DESCRIPTION OF THE MEDIUM TERM NOTES" briefly outlines some of the provisions of the Note Indenture. Please review the Note Indenture that we filed with the SEC for a full statement of those provisions. See "WHERE YOU CAN FIND MORE INFORMATION" on how to obtain a copy of the Note Indenture. You may also review the Note Indenture at the Note Trustee's offices at 101 Barclay Street 8W, New York, New York 10286.

        Capitalized terms used and defined under this heading "DESCRIPTION OF THE MEDIUM TERM NOTES" have the meanings given such terms as defined herein. Capitalized terms used under this heading which are not otherwise defined in this prospectus have the meanings given those terms in the Note Indenture. The summaries under this heading "DESCRIPTION OF THE MEDIUM TERM NOTES" are not detailed. Whenever particular provisions of the Note Indenture or terms defined in the Note Indenture are referred to, those statements are qualified by reference to the Note Indenture. References to article and section numbers under this heading "DESCRIPTION OF THE MEDIUM TERM NOTES," unless otherwise indicated, are references to article and section numbers of the Note Indenture.

        The Notes and all other debentures, notes or other evidences of indebtedness issued under the Note Indenture (referenced in this section as "debt securities") will be unsecured and will in all respects be equally and ratably entitled to the benefits of the Note Indenture, without preference, priority or distinction, and will rank equally with all other unsecured and unsubordinated indebtedness of SCANA. The Note Indenture does not limit the amount of debt securities that can be issued thereunder, and provides that our Notes may be executed in one or more series, as established in or pursuant to a board resolution and set forth in an officers' certificate or established in one or more supplemental indentures, and authenticated and delivered upon the delivery to the Note Trustee of

6


Table of Contents

such company orders, opinions and officers' certificates as may be required under the Note Indenture. (Sections 301 and 302). The Note Indenture also allows us to "reopen" any series of debt securities (including any series of Notes) by issuing additional debt securities of that series, if permitted by the terms of that series.

        Each prospectus supplement which accompanies this prospectus in connection with an offering of Notes will set forth some or all of the following information to describe a particular series of Notes:

Payment of Notes; Transfers; Exchanges

        Unless otherwise provided in a prospectus supplement, we will pay any interest due on each Note to the person in whose name that Note is registered as of the close of business on the record date relating to each Interest Payment Date. However, we will pay interest when the Notes mature (whether the Notes mature on their stated date of maturity, the date the Notes are redeemed or otherwise) to the person to whom the principal payment on the Notes is paid. If there is a default in the payment of interest on the Notes, we may either (1) choose a special record date which special record date is between ten and fifteen days prior to a payment date and pay on that payment date the holders of the Notes as of the close of business on that special record date, or (2) pay the holders of the Notes in any other lawful manner, all as more fully described in the Note Indenture. (Section 307)

        We will pay principal of, and any premium and interest due on, the Notes at maturity or upon earlier redemption or repayment of a Note upon surrender of that Note at the office of the paying agent (currently, the Note Trustee in New York, New York). (Sections 307, 308, 1001 and 1105) The applicable prospectus supplement identifies any other place of payment and any other paying agent. We may change the place at which the Notes will be payable, may appoint one or more additional paying agents and may remove any paying agent, all at our discretion. (Section 1002) Further, if we provide money to a paying agent to be used to make payments of principal of, premium (if any) or interest on any Note and that money has not rightfully been claimed two years after the applicable principal, premium or interest payment is due, then we may instruct the paying agent to remit that money to us, and any holder of a Note seeking those payments may thereafter look only to us for that money. (Section 1003)

        Except as provided in the following sentence or in a prospectus supplement, if principal of or premium (if any) or interest on the Notes is payable on a day which is not a Business Day, payment

7


Table of Contents

thereof will be postponed to the next Business Day, and no additional interest will accrue as a result of the delayed payment. (Section 114)

        "Business Day" means any day other than a Saturday or Sunday that is not a day on which banking institutions in Washington, D.C., or in New York, New York, are authorized or obligated by law or executive order to be closed.

        The "record date" will be 15 calendar days prior to each Interest Payment Date, whether or not that day is a Business Day, unless otherwise indicated in this prospectus or in the applicable prospectus supplement.

        You may transfer or exchange the Notes for other Notes of the same series, in authorized denominations (which are, unless otherwise stated in the prospectus supplement, denominations of $1,000 and any integral multiple thereof), and of like aggregate principal amount, at our office or agency in New York, New York (currently, the Note Trustee). At our discretion, we may change the place for registration and transfer of the Notes, and we may appoint one or more additional security registrars and remove any security registrar. The prospectus supplement will identify any additional place for registration of transfer and any additional security registrar. You are not responsible for paying a service charge for any transfer or exchange of the Notes, but you may have to pay a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of the Notes. (Sections 305, 307 and 1002).

Redemptions

        The Notes are subject to redemption prior to their stated maturity, as set forth in the relevant prospectus supplement. (Section 1101) If we redeem some or all of the Notes, the Note Trustee must notify you between 30 and 60 (or such shorter period specified in the applicable prospectus supplement) days before the redemption date (by first-class mail, postage prepaid) that some or all of the Notes will be redeemed. (Sections 106 and 1104) Further, if only a part of a Note is redeemed, then the holder of the unredeemed part of that Note will receive one or more new Notes. (Section 1107) The Notes will not be subject to any sinking fund. (Section 1201)

        Notwithstanding the foregoing, at any time, we may purchase the Notes or beneficial ownership interests in the Notes (if they are held in book-entry form) at any price in the open market or otherwise. In our sole discretion, we may hold, resell or retire any Notes or beneficial ownership interests in those Notes that we purchase.

Defaults

        The following are defaults under the Note Indenture with respect to debt securities issued under the Note Indenture:

8


Table of Contents

        Certain of these events become defaults only after the lapse of prescribed periods of time and/or notice from the Note Trustee. (Section 501)

        Upon the occurrence of a default under the Note Indenture, either the Note Trustee or the holder of at least 25% in principal amount of outstanding debt securities of the affected series may declare the principal of all outstanding debt securities of that series immediately due and payable. However, if the default is cured, the holders of a majority in principal amount of outstanding debt securities of the affected series may rescind that declaration and annul the declaration and its consequences. (Section 502)

        The holders of a majority in principal amount of outstanding debt securities of the affected series may direct the time, method and place of conducting any proceeding for the enforcement of the Note Indenture. (Section 512)

        No holder of any debt security of any series has the right to institute any proceeding with respect to the Note Indenture unless:

provided, however, that each holder of a Note shall have the right to enforce payment of that Note when due. (Sections 507 and 508)

        The Note Trustee must notify the holders of the debt securities of any series within 90 days after a default has occurred with respect to those debt securities, unless that default has been cured or waived, provided, however, except in the case of default in the payment of principal of, premium (if any), or interest or other amount payable on any debt security, the Note Trustee may withhold the notice if it determines that it is in the interest of those holders to do so. (Section 602)

        We are required under the Trust Indenture Act of 1939, as amended (the "Trust Indenture Act"), to furnish to the Note Trustee at least once every year a certificate as to our compliance with the conditions and covenants under the Note Indenture and to deliver reports, information and other documents to the Note Trustee and to file certain documents with the SEC. (Sections 704 and 1005)

Covenants, Consolidation, Merger, Etc.

        The Note Indenture provides that we will keep the property that we use in our business, or in the business of our subsidiaries, in good working order, and will improve it as necessary to properly conduct our business and that of our subsidiaries, as the case may be. (Section 1007) Except as described in the next paragraph, the Note Indenture provides that we will also maintain our corporate existence, rights and franchises and those of SCE&G and GENCO (collectively, our "Principal Subsidiaries"). (Section 1006) However, we are not required to preserve (a) the corporate existence of any of our subsidiaries other than our Principal Subsidiaries or (b) any such right or franchise if we determine that its preservation is not desirable in the conduct of our business or the business of our

9


Table of Contents

subsidiaries, consolidated as a whole, or its loss is not disadvantageous in any material respect to the holders of the outstanding debt securities of any series. (Section 1006)

        The Note Indenture provides that we may, without the consent of the holders of the debt securities, consolidate with, or sell, lease or convey all or substantially all of our assets to, or merge into another corporation, provided that (1) we are the continuing corporation, or, if not, the successor corporation assumes by a supplemental indenture our obligations under the Note Indenture and (2) immediately after giving effect to such transaction there will be no default in the performance of any such obligations. (Section 801)

        The Note Indenture provides that neither we nor our subsidiaries may issue, assume or guarantee any notes, bonds, debentures or other similar evidences of indebtedness for money borrowed ("Debt") secured by a mortgage, lien, pledge or other encumbrance ("Mortgages") upon any property of ours or our subsidiaries without effectively providing that the debt securities of each series issued under the Note Indenture (together with, if we so determine, any other indebtedness or obligation then existing or thereafter created ranking equally with those debt securities) are secured equally and ratably with (or prior to) such Debt so long as such Debt is so secured, except that this restriction will not apply to:

10


Table of Contents

        "Consolidated Net Tangible Assets" is defined as the total amount of assets appearing on the consolidated balance sheet of us and our subsidiaries subtracting, without duplication, the following:

Modification, Waiver and Meetings

        We may, without the consent of any holders of outstanding debt securities, enter into supplemental indentures for, including but not limited to, the following purposes:

        We may amend the Note Indenture for other purposes only with the consent of the holders of a majority in principal amount of each affected series of outstanding debt securities. However, we may not amend the Note Indenture without the consent of the holder of each affected outstanding debt security for the following purposes:

11


Table of Contents

        Except with respect to certain fundamental provisions, the holders of a majority in principal amount of outstanding debt securities of any series may waive past defaults with respect to that series and may waive our compliance with certain provisions of the Note Indenture with respect to that series.

DESCRIPTION OF THE JUNIOR SUBORDINATED NOTES

        SCANA will issue the Junior Subordinated Notes under a Junior Subordinated Indenture dated as of November 1, 2009 (the "Subordinated Indenture") between SCANA and U.S. Bank National Association, as trustee (the "Subordinated Note Trustee"). A copy of the Subordinated Indenture has been incorporated by reference as an exhibit to the registration statement of which this prospectus is a part. The information in this heading "DESCRIPTION OF THE JUNIOR SUBORDINATED NOTES" briefly outlines some of the provisions of the Subordinated Indenture. Please review the Subordinated Indenture that we filed with the SEC for a full statement of those provisions. See "WHERE YOU CAN FIND MORE INFORMATION" on how to obtain a copy of the Subordinated Indenture. You may also review the Subordinated Indenture at the Subordinated Note Trustee's offices at 1441 Main Street, Suite 775, Columbia, South Carolina 29201.

        Capitalized terms used and defined under this heading "DESCRIPTION OF THE JUNIOR SUBORDINATED NOTES" have the meanings given such terms as defined herein. Capitalized terms used under this heading that are not otherwise defined in this prospectus have the meanings given those terms in the Subordinated Indenture. The summaries under this heading "DESCRIPTION OF THE JUNIOR SUBORDINATED NOTES" are not detailed. Whenever particular provisions of the Subordinated Indenture or terms defined in the Subordinated Indenture are referred to, those statements are qualified by reference to the Subordinated Indenture. References to article and section numbers under this heading "DESCRIPTION OF THE JUNIOR SUBORDINATED NOTES," unless otherwise indicated, are references to article and section numbers of the Subordinated Indenture.

General

        The Junior Subordinated Notes will be our unsecured obligation and are junior in right of payment to our Priority Indebtedness, as described under the caption "Subordination" herein.

        Because we are a holding company that conducts all of our operations through our subsidiaries, our ability to meet our obligations under the Junior Subordinated Notes is dependent on the earnings and cash flows of those subsidiaries and the ability of those subsidiaries to pay dividends or to advance or repay funds to us. Holders of Junior Subordinated Notes will generally have a junior position to claims of creditors of our subsidiaries, including trade creditors, debt holders, secured creditors, taxing authorities, guarantee holders and any preferred stockholders. As of August 31, 2012 we had no outstanding shares of preferred stock. In addition, as of August 31, 2012, our subsidiaries had approximately $4.1 billion in aggregate principal amount of outstanding long-term debt (including securities due within one year).

        The Subordinated Indenture does not limit the amount of Junior Subordinated Notes that we may issue. We may issue Junior Subordinated Notes from time to time under the Subordinated Indenture in one or more series by entering into supplemental indentures or by resolutions of our board of directors or duly authorized officers authorizing the issuance, which Subordinated Indenture provides for the authentication and delivery of the Junior Subordinated Notes upon the delivery to the Subordinated Note Trustee of an opinion of counsel and officer's certificate as contemplated by the Subordinated Indenture. (Section 2.1) A form of supplemental indenture to the Subordinated Indenture is an exhibit to the registration statement.

        The Subordinated Indenture does not protect the holders of Junior Subordinated Notes if we engage in a highly leveraged transaction.

Provisions of a Particular Series

        The Junior Subordinated Notes of a series need not be issued at the same time, bear interest at the same rate or mature on the same date. Unless otherwise provided in the terms of a series, a series

13


Table of Contents

may be reopened, without notice to or consent of any holder of outstanding Junior Subordinated Notes, for issuances of additional Junior Subordinated Notes of that series. The prospectus supplement for a particular series of Junior Subordinated Notes will describe the terms of that series, including, if applicable, some or all of the following:

        The prospectus supplement will also indicate any special tax implications of the Junior Subordinated Notes and any provisions granting special rights to holders when a specified event occurs.

Conversion or Redemption

        No Junior Subordinated Note will be subject to conversion, amortization or redemption, unless otherwise provided in the applicable prospectus supplement. Any provisions relating to the conversion

14


Table of Contents

or redemption of Junior Subordinated Notes will be set forth in the applicable prospectus supplement, including whether conversion is mandatory or at our option. If no redemption date or redemption price is indicated with respect to a Junior Subordinated Note, we may not redeem the Junior Subordinated Note prior to its stated maturity. Junior Subordinated Notes subject to redemption by us will be subject to the following terms:

        We will not be required to:

Payment and Transfer; Paying Agent

        The paying agent will pay the principal of any Junior Subordinated Notes only if those Junior Subordinated Notes are surrendered to it. Unless we state otherwise in the applicable prospectus supplement, the paying agent will pay principal, interest and premium, if any, on Junior Subordinated Notes, subject to such surrender, where applicable, at its office or by (1) check mailed to the address of the person entitled to that interest as that address appears in the security register for those Junior Subordinated Notes or (2) wire transfer to an account maintained for the person entitled to that interest as specified in the security register for those Junior Subordinated Notes, provided proper transfer instructions have been received by the record date. (Section 4.1)

        Unless we state otherwise in the applicable prospectus supplement, the Subordinated Note Trustee will act as paying agent for the Junior Subordinated Notes, and the principal corporate trust office of the Subordinated Note Trustee will be the office through which the paying agent acts. We may, however, change or add paying agents or approve a change in the office through which a paying agent acts. (Section 4.4)

        Any money that we have paid to a paying agent for principal or interest on any Junior Subordinated Notes that remains unclaimed at the end of two years after that principal or interest has become due will be repaid to us at our request. After repayment to the Company, holders should look only to us for those payments. (Section 12.4)

        Fully registered securities may be transferred or exchanged at the corporate trust office of the Subordinated Note Trustee or at any other office or agency we maintain for those purposes, without the payment of any service charge except for any tax or governmental charge and related expenses. (Section 2.5)

Covenants

        Under the Subordinated Indenture we will:

Consolidation, Merger or Sale

        The Subordinated Indenture provides that we may consolidate or merge with or into, or sell all or substantially all of our properties and assets to, another corporation or other entity, provided that any successor assumes our obligations under the Subordinated Indenture and the Junior Subordinated Notes issued under the Subordinated Indenture. We must also deliver an opinion of counsel to the Subordinated Note Trustee affirming our compliance with all conditions in the Subordinated Indenture relating to the transaction. When the conditions are satisfied, the successor will succeed to and be substituted for us under the Subordinated Indenture, and, in the case of a sale of all or substantially all of our assets, we will be relieved of our obligations under the Subordinated Indenture and the Junior Subordinated Notes issued under it. (Sections 11.1, 11.2 and 11.3)

Events of Default

        Event of Default, when used in the Subordinated Indenture, will mean any of the following with respect to Junior Subordinated Notes of any series:

        In the case of a general covenant default described above, the Subordinated Note Trustee may extend the grace period. In addition, if holders of a particular series have given a notice of default, then holders of at least the same percentage of Junior Subordinated Notes of that series, together with the Subordinated Note Trustee, may also extend the grace period. The grace period will be automatically extended if we have initiated and are diligently pursuing corrective action.

16


Table of Contents

        An Event of Default for a particular series of Junior Subordinated Notes does not necessarily constitute an Event of Default for any other series of Junior Subordinated Notes issued under the Subordinated Indenture. Additional events of default may be established for a particular series and, if established, will be described in the applicable prospectus supplement.

        If such an event of default under the Subordinated Indenture occurs due to our failure to pay principal or interest on the Junior Subordinated Notes, the Trustee or the holders of not less than 25% in principal amount of all the then outstanding Junior Subordinated Notes will have the right to declare the principal amount of the Junior Subordinated Notes and any accrued interest thereon, immediately due and payable. If such an event of default under the Subordinated Indenture occurs as a result of our failure to perform certain other covenants or as a result of certain events of bankruptcy, the Trustee or the holders of not less than 25% in principal amount of all of the then outstanding securities issued under the Subordinated Indenture (including the Junior Subordinated Notes then outstanding) as to which such event of default has occurred will have the right to declare, voting as one class, the principal amount of the Junior Subordinated Notes and any accrued interest thereon, immediately due and payable. If this happens, subject to certain conditions, the holders of a majority of the aggregate principal amount of the Junior Subordinated Notes of that series can void the declaration. (Section 6.1)

        The Subordinated Note Trustee must give the holders of Junior Subordinated Notes notice of any default known to it; however, the Subordinated Note Trustee may withhold notice to the holders of Junior Subordinated Notes of any default (except in the payment of principal or interest) if it in good faith considers the withholding of notice to be in the interests of the holders. Other than its duties in case of a default, a Trustee is not obligated to exercise any of its rights or powers under the Subordinated Indenture at the request, order or direction of any holders, unless the holders offer the Subordinated Note Trustee reasonable indemnity. If they provide this reasonable indemnification, the holders of a majority in principal amount of any series of Junior Subordinated Notes may direct the time, method and place of conducting any proceeding or any remedy available to the Subordinated Note Trustee, or exercising any power conferred upon the Subordinated Note Trustee, for any series of Junior Subordinated Notes. (Sections 6.6, 6.7, 7.1 and 7.2)

        The holder of any Junior Subordinated Note will have an absolute and unconditional right to receive payment of the principal, any premium and, within certain limitations, any interest on that Junior Subordinated Note on its maturity date or redemption date and to enforce those payments. (Section 14.2)

Option to Extend Interest Payment Period

        If elected in the applicable supplemental indenture, we may defer interest payments by extending the interest payment period for the number of consecutive extension periods specified in the applicable prospectus supplement (each, an "Extension Period"). Other details regarding the Extension Period will also be specified in the applicable prospectus supplement. No Extension Period may end on a date other than an interest payment date or extend beyond the maturity of the applicable series of Junior Subordinated Notes. At the end of the Extension Period(s), we will pay all interest then accrued and unpaid, together with additional interest thereon at the interest rate specified for the applicable series of Junior Subordinated Notes, to the extent permitted by applicable law. (Section 2.10)

Satisfaction and Discharge; Defeasance

        We may discharge all our obligations (except those described below) to holders of the Junior Subordinated Notes issued under the Subordinated Indenture, which Junior Subordinated Notes have not already been delivered to the Subordinated Note Trustee for cancellation and which either have become due and payable or are by their terms due and payable within one year, or are to be called for redemption within one year, by depositing with the Subordinated Note Trustee an amount certified to

17


Table of Contents

be sufficient to pay when due the principal, interest and premium, if any, on all outstanding Junior Subordinated Notes. However, certain of our obligations under the Subordinated Indenture will survive, including with respect to the following:

        Unless we elect differently in the applicable supplemental indenture, we will be discharged from our obligations on the Junior Subordinated Notes of any series at any time if we deposit with the Subordinated Note 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 Junior Subordinated Notes of the series. If this happens, the holders of the Junior Subordinated Notes of the series will not be entitled to the benefits of the Subordinated Indenture, except for registration of transfer and exchange of Junior Subordinated Notes and replacement of lost, stolen or mutilated Junior Subordinated Notes. (Section 12.5)

Modification of Subordinated Indenture; Waiver

        Under the Subordinated Indenture our rights and obligations and the rights of the holders of the Junior Subordinated Notes may be modified with the consent of the holders of a majority in aggregate principal amount of the outstanding Junior Subordinated Notes of all series affected by the modification (voting as one class). No modification of the principal or interest payment terms of the Junior Subordinated Notes or of the provisions of the Subordinated Indenture to (1) reduce the percentage of principal amount of holders of Junior Subordinated Notes required for modifications or (2) modify the subordination provisions thereof adverse to the holders of Junior Subordinated Notes, is effective against any holder without its consent. (Section 10.2) In addition, we may supplement the Subordinated Indenture to create one or more new series of Junior Subordinated Notes and for certain other purposes, without the consent of any holders of Junior Subordinated Notes. (Section 10.1)

        The holders of a majority of the outstanding Junior Subordinated Notes of all series with respect to which a default has occurred and is continuing may waive a default for all those series, except a default in the payment of principal or interest, or any premium, on any Junior Subordinated Notes or a default with respect to a covenant or provision which cannot be amended or modified without the consent of the holder of each outstanding Junior Subordinated Note of the series affected. (Section 6.6)

        In addition, under certain circumstances, the holders of a majority of the outstanding Junior Subordinated Notes of any series may waive in advance, for that series, our compliance with certain restrictive provisions of the Subordinated Indenture under which those Junior Subordinated Notes were issued. (Section 4.7)

Concerning the Subordinated Note Trustee

        U.S. Bank National Association is the Subordinated Note Trustee under the Subordinated Indenture. U.S. Bank National Association may be a lender under our, or our subsidiaries or affiliates', credit agreements and may provide other commercial banking and other services to us and/or our subsidiaries or affiliates.

18


Table of Contents

        The Subordinated Note Trustee will perform only those duties that are specifically described in the Subordinated Indenture unless an event of default thereunder occurs and is continuing. The Subordinated Note Trustee is under no obligation to exercise any of its powers under the Subordinated Indenture at the request of any holder of Junior Subordinated Notes unless that holder offers reasonable indemnity to the Subordinated Note Trustee against the costs, expenses and liabilities which it might incur as a result. (Sections 7.1 and 7.2)

        The Subordinated Note Trustee administers its corporate trust business at 1441 Main Street, Suite 775, Columbia, South Carolina 29201.

Subordination

        Each series of Junior Subordinated Notes will be subordinate and junior in right of payment, to the extent set forth in the Subordinated Indenture, to all Priority Indebtedness as defined below. If:

then, unless otherwise specified in the prospectus supplement, the holders of Priority Indebtedness generally will have the right to receive payment, in the case of the first instance, of all amounts due or to become due upon that Priority Indebtedness, and, in the case of the second and third instances, of all amounts due on that Priority Indebtedness, or we will make provision for those payments, before the holders of any Junior Subordinated Notes have the right to receive any payments of principal or interest on their Junior Subordinated Notes. (Sections 14.1 and 14.9)

        Priority Indebtedness means, with respect to any series of Junior Subordinated Notes, the principal, premium, interest and any other payment in respect of any of the following:

other than obligations ranking on a parity with or junior to the Junior Subordinated Notes.

        Priority Indebtedness will not include indebtedness to our subsidiaries. (Section 1.1)

19


Table of Contents

        Priority Indebtedness will be entitled to the benefits of the subordination provisions in the Subordinated Indenture irrespective of the amendment, modification or waiver of any term of the Priority Indebtedness. (Section 14.7)

        As of August 31, 2012, SCANA had approximately $1.0 billion principal amount of outstanding long-term debt, on an unconsolidated basis (including securities due within one year) that would be senior to the Junior Subordinated Notes. Holders of Junior Subordinated Notes will generally have a junior position to claims of creditors of our subsidiaries, including trade creditors, debt holders, secured creditors, taxing authorities, guarantee holders and any preferred stockholders. In addition to trade debt, many of our operating subsidiaries have ongoing intercompany debt programs used to finance their business activities. All of this intercompany debt will be effectively senior to the Junior Subordinated Notes.

        Neither our Subordinated Indenture nor the Junior Subordinated Notes contain restrictions on the amount of additional indebtedness that we or our subsidiaries may incur. We and our subsidiaries expect to incur additional indebtedness from time to time that will be senior to the Junior Subordinated Notes.


DESCRIPTION OF THE COMMON STOCK

DESCRIPTION OF THE FIRST MORTGAGE BONDS

General

        SCE&G will issue the Bonds in one or more series under an Indenture, dated as of April 1, 1993, as supplemented (the "Mortgage"), between SCE&G and The Bank of New York Mellon Trust Company, N.A. (successor to NationsBank of Georgia, National Association), as trustee (the "Bond Trustee"). The term "Bonds" in this prospectus also includes all other debt securities issued and outstanding under the Mortgage. A copy of the Mortgage has been incorporated by reference as an exhibit to the registration statement of which this prospectus is a part. The information under this heading "DESCRIPTION OF THE FIRST MORTGAGE BONDS" briefly outlines some of the provisions of the Mortgage. Please review the Mortgage that we filed with the SEC for a full statement of those provisions. See "WHERE YOU CAN FIND MORE INFORMATION" on how to obtain a copy of the Mortgage. You may also review the Mortgage at the Bond Trustee's offices at 900 Ashwood Parkway, Suite 425, Atlanta, Georgia 30338.

        Capitalized terms used and defined under this heading "DESCRIPTION OF THE FIRST MORTGAGE BONDS" have the meanings given such terms as defined herein. Capitalized terms used under this heading "DESCRIPTION OF THE FIRST MORTGAGE BONDS" which are not otherwise defined in this prospectus have the meanings given those terms in the Mortgage.

Provisions of a Particular Series

        The Bonds of a series need not be issued at the same time, bear interest at the same rate or mature on the same date. Unless otherwise provided in the terms of a series, a series may be reopened, without notice to or consent of any holder of outstanding Bonds, for issuances of additional Bonds of that series. Each prospectus supplement relating to a series of Bonds which accompanies this prospectus will set forth the following information to describe the series of Bonds, unless the information is the same as the information included in this section:

22


Table of Contents

Payment of Bonds; Transfers; Exchanges

        We will pay any interest which is due on each New Bond to the person in whose name that New Bond is registered as of the close of business on the record date relating to the Interest Payment Date. (Section 207) However, we will pay interest which is payable when the Bonds mature (whether the Bonds mature on their stated date of maturity, the date the Bonds are redeemed or otherwise) to the person to whom the relevant principal payment on the Bonds is to be paid.

        We will pay principal of, and any premium and interest on, the Bonds at our office or agency in Atlanta, Georgia (currently, the Bond Trustee). The applicable prospectus supplement for any series of Bonds will specify any other place of payment and any other paying agent. We may change the place at which the Bonds will be payable, may appoint one or more additional paying agents (including us) and may remove any paying agent, all at our discretion. (Section 702)

        Except as provided in a prospectus supplement, if principal of or premium (if any) or interest on the Bonds is payable on a day which is not a Business Day, payment thereof may be postponed to the next succeeding Business Day, and no additional interest will accrue as a result of the delayed payment. (Section 116)

        "Business Day" means any day, other than a Saturday or Sunday, which is not a day on which banking institutions or trust companies in Atlanta, Georgia are generally authorized or required by law, regulation or executive order to remain closed. (Section 101)

        You may transfer or exchange the Bonds for other Bonds of the same series, in authorized denominations, and of like tenor and aggregate principal amount, at our office or agency in Atlanta, Georgia (currently, the Bond Trustee). At our discretion, we may change the place for registration and transfer of the Bonds, and we may appoint one or more additional security registrars (including us) and remove any security registrar. The prospectus supplement will identify any additional place for registration of transfer and any additional security registrar. You are not responsible for paying a service charge for any transfer or exchange of the Bonds, but you may have to pay a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of the Bonds. (Sections 202 and 205)

Redemption

        The Bonds are subject to redemption, as set forth in the relevant prospectus supplement, only upon notice by mail (unless waived) not less than 30 days (or such other period set forth in the relevant prospectus supplement) prior to the redemption date. If less than all the Bonds of a series are to be redeemed, the particular Bonds to be redeemed will be selected by the method as shall be provided for any particular series, or in the absence of any such provision, by any method as the security registrar deems fair and appropriate. (Sections 109, 903 and 904)

23


Table of Contents

        We may, in any notice of redemption, make any redemption conditional upon receipt by the Bond Trustee, on or prior to the date fixed for redemption, of money sufficient to pay the redemption price. If the Bond Trustee has not received that money, we will not be required to redeem those Bonds and we will then give notice to that effect. (Section 904)

Security

        The Bonds of each series will be equally and ratably secured under the Mortgage. The Bonds are secured by the lien of the Mortgage on substantially all of our properties used in the generation, purchase, transmission, distribution and sale of electricity which have not been released from, or transferred not subject to, the lien of the Mortgage, and any other property which we may elect to subject to the lien of the Mortgage. (Granting Clauses)

        If we merge or are consolidated with another corporation and certain conditions set forth in the Mortgage are satisfied, the existing mortgage or deed of trust or similar indenture entered into by such corporation may be designated as a "Class A Mortgage" and bonds issued thereunder would be "Class A Bonds" for purpose of the Mortgage. In that event, the Bonds will be secured, additionally, by such Class A Bonds as may be issued under the Class A Mortgage and deposited with the Bond Trustee and by the lien of the Mortgage, which lien would be junior to the lien of Class A Mortgage with respect to the property subject to such Class A Mortgage. (Section 1206) Presently, we have no Class A Bonds outstanding.

        The lien of the Mortgage is subject to the prior first mortgage lien of a Class A Mortgage, if any, liens on after-acquired property existing at the time of acquisition and various permitted liens, including:

        The following, among other things, are excepted from the lien of the Mortgage:

24


Table of Contents

        The Mortgage contains provisions subjecting (with certain exceptions and limitations and subject to the prior lien of a Class A Mortgage, if any, and the provisions of the U.S. Bankruptcy Code) after-acquired electric utility property to the lien of the Mortgage. (Granting Clauses) Notwithstanding the foregoing, it may be necessary to comply with applicable recording requirements to perfect such lien on after-acquired electric utility property.

        The Mortgage provides that the Bond Trustee has a lien upon the property subject to the lien of the Mortgage, for the payment of its compensation and expenses. This Bond Trustee's lien is prior to the lien on behalf of the holders of the Bonds. (Section 1607)

Issuance of Bonds

        The maximum principal amount of Bonds which we may issue under the Mortgage is unlimited. Under the Mortgage, Bonds may be authenticated and delivered, upon receipt by the Bond Trustee of a supplemental indenture, a board resolution or an officer's certificate pursuant thereto, together with a company order to the Bond Trustee, an opinion of counsel and an officer's certificate, subject to the further requirements of the Mortgage described below. (Sections 201 and 301)

        We may issue Bonds of any series from time to time on the basis of, and in an aggregate principal amount not exceeding the sum of:

        Property Additions are generally defined to include any property subject to the lien of the Mortgage (the "Mortgaged Property") which we may elect to designate as such, except (with certain exceptions) goodwill, going concern value, intangible property or any property the cost of acquisition or construction of which is properly chargeable to an operating expense account. (Sections 101 and 104)

        Based upon Property Additions certified on January 30, 2012 to the Bond Trustee as of December 31, 2011 (the last date of certification of Property Additions under the Mortgage), we have Unfunded Net Property Additions of approximately $2.6 billion, sufficient to permit the issuance of approximately $1.8 billion of additional Bonds on the basis thereof. At August 31, 2012, we had $250 million of credits from the retirement of Bonds under the Mortgage, which may be used as the basis for the authentication of additional Bonds under the Mortgage.

25


Table of Contents

        With certain exceptions in the case of Bonds issued on the basis of Class A Bonds and retired Bonds as described above, we can issue Bonds only if our Adjusted Net Earnings (as defined in the Mortgage) for 12 consecutive months within the preceding 18 months is at least twice the Annual Interest Requirements (as defined in the Mortgage) on:

Release of Property

        We may obtain the release of property from the lien of the Mortgage either upon the basis of an equal amount of Unfunded Net Property Additions or upon the basis of the deposit of cash or a credit for retired Bonds. We may also obtain the release of property upon the basis of the release of the property from the lien of a Class A Mortgage, if any. (Article Ten)

Withdrawal of Cash

        We may withdraw cash deposited as the basis for the issuance of Bonds and cash representing certain payments in respect of Class A Bonds, if any, designated as the basis for the issuance of Bonds or the withdrawal of cash ("Designated Class A Bonds") upon the basis of (1) Unfunded Net Property Additions in an amount equal to ten-sevenths of such cash, (2) an equal amount of retired Bonds or (3) an equal amount of Class A Bonds which are not Designated Class A Bonds. (Sections 601 and 1202) In addition, we may withdraw any other cash (with certain exceptions) upon the basis of (a) an equal amount of Unfunded Net Property Additions, or (b) ten-sevenths of the amount of retired Bonds, or may apply such cash to (y) the purchase of Bonds (at prices not exceeding ten-sevenths of the principal amount thereof) or (z) the redemption or payment at stated maturity of Bonds. (Sections 601 and 1005)

Modification of Mortgage

        We may, without the consent of any holders of outstanding Bonds, enter into supplemental indentures for, including but not limited to, the following purposes:

        We may amend the Mortgage for other purposes only with the consent of the holders of a majority in principal amount of the Bonds then outstanding, considered as one class, unless such amendment directly affects the rights of the holders of Bonds of one or more, but less than all, series, in which case only the consent of the holders of a majority in principal amount of the affected series of the Bonds

then outstanding, considered as one class, need be obtained. However, without the consent of the holder of each affected outstanding Bond, we may not amend the Mortgage for the following purposes:

Events of Default

        Each of the following events is an Event of Default under the Mortgage:

        If an Event of Default occurs and is continuing, either the Bond Trustee or the Holders of 25% in principal amount of the Outstanding Bonds may declare the principal amount of all of the Outstanding Bonds to be immediately due and payable. After the declaration of acceleration has been made, but before the sale of any of the Mortgaged Property and before the Bond Trustee has obtained a judgment or decree for payment of money, the Event of Default giving rise to such declaration of acceleration will be deemed to be waived, and such declaration and its consequences will be rescinded and annulled, if we (a) pay to the Bond Trustee all overdue interest, principal and any premium on any Outstanding Bonds and (b) cure any other such Event of Default. (Sections 1102 and 1117)

        The Holders of a majority in principal amount of the Outstanding Bonds may direct the time, method and place of conducting any proceeding for the enforcement of the Mortgage available to the Bond Trustee or exercising any trust or power conferred on the Bond Trustee. No Holder of any Bond

27

has the right to institute any proceeding with respect to the Mortgage, or for the appointment of a receiver or for any other remedy thereunder, unless:

provided, however, that each Holder of a Bond has the right to enforce payment of that Bond when due. (Sections 1111, 1112 and 1116)

        In addition to the rights and remedies provided in the Mortgage, the Bond Trustee may exercise any right or remedy available to the Bond Trustee in its capacity as the owner and holder of Class A Bonds, if any, which arises as a result of a default under any Class A Mortgage. (Section 1119)

Defeasance; Satisfaction and Discharge

        Upon receipt by the Bond Trustee of moneys or Eligible Obligations (as defined in the Mortgage), or both, sufficient to pay when due the principal of and premium, if any, and interest, if any, due and to become due on the Bonds together with a company order and opinion of counsel required by the Mortgage, the holders of the Bonds or portions thereof in respect of which such deposit was made will no longer be entitled to the benefit of certain of our covenants under the Mortgage, and the Bond Trustee will, upon receipt of a company order as required by the Mortgage, acknowledge in writing that such Bonds or portions thereof are deemed to have been paid for purposes of the Mortgage and that our entire indebtedness in respect of the Mortgage has been deemed to have been satisfied and discharged. Notwithstanding the satisfaction and discharge of any Bonds as described above, certain of our obligations and the obligations of the Bond Trustee shall survive. (Section 1301)

Restrictions on Payment of Dividends

        The Mortgage prohibits us from declaring and paying dividends on any shares of our common stock except from either (1) the excess (the "Surplus") of our net assets over our Capital (as defined herein) or (2) if there is no Surplus, our net profits for the fiscal year in which the dividend is declared and/or the preceding fiscal year; provided, that no dividends may be declared if and while our Capital is significantly impaired as described in the Mortgage. "Capital" is defined in the Mortgage to mean the part of the consideration we received for any shares of our capital stock as determined by our board of directors to be capital or, if our board has not made such a determination, the aggregate par amount of shares having a par value plus the amount of consideration for such shares without par value. All of the outstanding shares of our common stock are held of record by SCANA. (Section 711)

Evidence of Compliance and Indemnification of Bond Trustee

        The Trust Indenture Act requires that we give the Bond Trustee, at least annually, a brief statement as to our compliance with the conditions and covenants under the Mortgage and periodically deliver reports, information and other documents to the Bond Trustee and file certain documents with the SEC. (Article Eight)

        The Bond Trustee will be under no obligation to exercise any of the rights or powers vested in it by the Mortgage at the request or direction of any Holder pursuant to the Mortgage, unless such Holder shall have offered to the Bond Trustee reasonable security or indemnity against the costs,

expenses and liabilities which might be incurred by it in compliance with such request or direction. (Section 1603)

Our Relationship with the Bond Trustee

        The Bond Trustee and/or one or more of its affiliates, may be lenders under our, or our subsidiaries' or affiliates', credit agreements and may provide other commercial banking, investment banking and other services to us and/or our subsidiaries or affiliates. The Bond Trustee will be permitted to engage in other transactions with us and/or our subsidiaries or affiliates; however, if the Bond Trustee acquires any conflicting interest, as defined in the Trust Indenture Act, it must eliminate the conflict or resign.


BOOK-ENTRY SYSTEM

        If provided in the applicable prospectus supplement, except under the circumstances described therein, we will issue each of the Notes, Junior Subordinated Notes or Bonds sold pursuant to this prospectus (the "Securities") as one or more global certificates (each a "Global Certificate"), each of which will represent beneficial interests in the Securities. We will deposit those Global Certificates with, or on behalf of The Depository Trust Company, New York, New York or another depository which we subsequently designate (the "Depository") relating to the Securities, and register them in the name of a nominee of the Depository.

        So long as the Depository, or its nominee, is the registered owner of a Global Certificate, the Depository or its nominee, as the case may be, will be considered the owner of that Global Certificate. We will make payments of principal of, any premium, and interest on the Global Certificate to the Depository or its nominee, as the case may be, as the registered owner of that Global Certificate. Except as set forth in the applicable prospectus supplement, owners of a beneficial interest in a Global Certificate will not be entitled to have any individual Securities registered in their names, will not receive or be entitled to receive physical delivery of any Securities and will not be considered the owners of Securities.

        Accordingly, to exercise any of the rights of the registered owners of the Securities, each person holding a beneficial interest in a Global Certificate must rely on the procedures of the Depository. If that person is not a DTC participant, then that person must also rely on procedures of the DTC participant through which that person holds its interest.
