FORWARD-LOOKING STATEMENTS

This prospectus supplement, the accompanying prospectus and the documents they incorporate by reference contain, and any related free writing prospectus issued by us may contain, statements that are not historical fact and constitute “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. Forward-looking statements are based upon assumptions with respect to the future, involve risks and uncertainties, and are not guarantees of performance. These forward-looking statements represent our estimates and assumptions only as of the respective dates of the documents in which such forward-looking statements appear. We assume no obligation to update or revise any forward-looking statement as a result of new information, future events or other factors.

When we use words such as “believes,” “expects,” “anticipates,” “plans,” “estimates,” “projects,” “forecasts,” “contemplates,” “assumes,” “depends,” “should,” “could,” “would,” “will,” “confident,” “may,” “can,” “potential,” “possible,” “proposed,” “target,” “pursue,” “outlook,” “maintain,” or similar expressions, or when we discuss our guidance, strategy, plans, goals, opportunities, projections, initiatives, objectives or intentions, we are making forward-looking statements.

Factors, among others, that could cause our actual results and future actions to differ materially from those described in forward-looking statements include:

• actions and the timing of actions, including decisions, new regulations, and issuances of permits and other authorizations by the California Public Utilities Commission, U.S. Department of Energy, California Division of Oil, Gas, and Geothermal Resources, Federal Energy Regulatory Commission, U.S. Environmental Protection Agency, Pipeline and Hazardous Materials Safety Administration, Los Angeles County Department of Public Health, states, cities and counties, and other regulatory and governmental bodies in the United States and other countries in which we operate;

• the timing and success of business development efforts and construction projects, including risks in obtaining or maintaining permits and other authorizations on a timely basis, risks in completing construction projects on schedule and on budget, and risks in obtaining the consent and participation of partners;

• the resolution of civil and criminal litigation and regulatory investigations;

• deviations from regulatory precedent or practice that result in a reallocation of benefits or burdens among shareholders and ratepayers; modifications of settlements; and delays in, or disallowance or denial of, regulatory agency authorizations to recover costs in rates from customers (including with respect to regulatory assets associated with the San Onofre Nuclear Generating Station facility and 2007 wildfires) or regulatory agency approval for projects required to enhance safety and reliability;

• the availability of electric power, natural gas and liquefied natural gas, and natural gas pipeline and storage capacity, including disruptions caused by failures in the transmission grid, moratoriums on the withdrawal or injection of natural gas from or into storage facilities, and equipment failures;

• changes in energy markets; volatility in commodity prices; moves to reduce or eliminate reliance on natural gas; and the impact on the value of our investment in natural gas storage and related assets from low natural gas prices, low volatility of natural gas prices and the inability to procure favorable long-term contracts for storage services;

• risks posed by actions of third parties who control the operations of our investments, and risks that our partners or counterparties will be unable or unwilling to fulfill their contractual commitments;

• weather conditions, natural disasters, accidents, equipment failures, computer system outages, explosions, terrorist attacks and other events that disrupt our operations, damage our facilities and systems, cause the release of greenhouse gases, radioactive materials and harmful emissions, cause

S-1

wildfires and subject us to third-party liability for property damage or personal injuries, fines and penalties, some of which may not be covered by insurance (including costs in excess of applicable policy limits) or may be disputed by insurers;

• cybersecurity threats to the energy grid, storage and pipeline infrastructure, the information and systems used to operate our businesses and the confidentiality of our proprietary information and the personal information of our customers and employees;

• capital markets and economic conditions, including the availability of credit and the liquidity of our investments; and fluctuations in inflation, interest and currency exchange rates and our ability to effectively hedge the risk of such fluctuations;

• changes in the tax code as a result of potential federal tax reform, such as the elimination of the deduction for interest and non-deductibility of all, or a portion of, the cost of imported materials, equipment and commodities;

• changes in foreign and domestic trade policies and laws, including border tariffs, revisions to favorable international trade agreements, and changes that make our exports less competitive or otherwise restrict our ability to export;

• the ability to win competitively bid infrastructure projects against a number of strong and aggressive competitors;

• expropriation of assets by foreign governments and title and other property disputes;

• the impact on reliability of San Diego Gas & Electric Company’s (“SDG&E”) electric transmission and distribution system due to increased amount and variability of power supply from renewable energy sources;

• the impact on competitive customer rates due to the growth in distributed and local power generation and the corresponding decrease in demand for power delivered through SDG&E’s electric transmission and distribution system and from possible departing retail load resulting from customers transferring to Direct Access and Community Choice Aggregation; and

• other uncertainties, some of which may be difficult to predict and are beyond our control.

RISK FACTORS

Investment in the notes involves risks. You should carefully consider the risk factors incorporated into this prospectus supplement and the accompanying prospectus by reference to our most recent Annual Report on Form 10-K and all other information contained or incorporated by reference into this prospectus supplement and the accompanying prospectus, as updated by our subsequent filings under the Securities Exchange Act of 1934, as amended, before acquiring any of such notes. The occurrence of any of these risks might cause you to lose all or part of your investment in the notes. See also “Forward-Looking Statements.”

USE OF PROCEEDS

The net proceeds from the sale of the notes will be approximately $         million (after deducting the underwriting discount but before deducting our estimated offering expenses), and will become part of our general treasury funds. We intend to use the net proceeds to repay outstanding commercial paper, which bears interest at rates of 1.40% per year or less and matures at various dates in June 2017. We estimate that our expenses for this offering, excluding the underwriting discount, will be approximately $1,000,000.

As described above, net proceeds from this offering will be used to repay outstanding commercial paper. One or more of the underwriters participating in this offering and/or their affiliates may hold positions in our commercial paper and one or more of the underwriters may act as dealers under our commercial paper programs. To the extent that net proceeds from this offering are applied to repay our commercial paper held by any of the underwriters or their affiliates, they will receive proceeds of this offering through the repayment of that commercial paper. If 5% or more of the net proceeds of this offering (not including the underwriting discount) is used to repay our outstanding commercial paper held by at least one of the underwriters or their affiliates, this offering will be conducted in accordance with FINRA Rule 5121. In such event, such underwriter or underwriters will not confirm sales of the notes to accounts over which they exercise discretionary authority without the prior written approval of the customer. See “Underwriting (Conflicts of Interest)—Conflicts of Interest.”

S-5

DESCRIPTION OF THE NOTES

The notes will be a series of our senior debt securities issued under an indenture between Sempra Energy, as issuer, and U.S. Bank National Association, as trustee. In this section and under the caption “Description of Debt Securities” in the accompanying prospectus, references to “Sempra Energy,” “we,” “our” and “us” mean Sempra Energy excluding its subsidiaries, unless otherwise expressly stated or the context otherwise requires.

The summary of selected provisions of the notes and the indenture appearing below supplements, and to the extent inconsistent, supersedes and replaces, the description of the general terms and provisions of the senior debt securities and the indenture contained in the accompanying prospectus. This summary is not complete and is qualified by reference to provisions of the notes and the indenture. Forms of the notes and the indenture have been or will be filed with the SEC and you may obtain copies as described under “Where You Can Find More Information” in the accompanying prospectus, except that correspondence to us as described in that section in the accompanying prospectus should be sent to the following address: 488 8th Avenue, San Diego, California 92101, Attention: Corporate Secretary, Telephone: (619) 696-2000.

Interest Rate and Maturity

The notes will bear interest at the rate of         % per year computed on the basis of a 360-day year of twelve 30-day months. Interest on the notes will accrue from                 , 2017 and will be payable semi-annually in arrears on                 and                 of each year, beginning on                 ,         , to the holders of record at the close of business on the immediately preceding                 and                 , respectively.

The notes will mature on                 , 2027. The notes are subject to earlier redemption at our option as described under “—Optional Redemption.”

If any interest payment date, redemption date or the maturity date of the notes is not a business day at any place of payment, then payment of the principal, premium, if any, and interest may be made on the next business day at that place of payment. In that case, no interest will accrue on the amount payable for the period from and after the applicable interest payment date, redemption date or maturity date, as the case may be.

Ranking

The notes will be our unsecured and unsubordinated obligations and will rank on a parity in right of payment with all of our other unsecured and unsubordinated indebtedness and guarantees. The notes will rank senior to all of our existing and future indebtedness, if any, that is subordinated to the notes. The notes will be effectively subordinated to any secured indebtedness we have or may incur (to the extent of the collateral securing that indebtedness). The notes are our obligations exclusively, and are not the obligations of any of our subsidiaries. Because we conduct our operations primarily through our subsidiaries and substantially all of our consolidated assets are held by our subsidiaries, the notes will be effectively subordinated to all existing and future indebtedness and other liabilities of our subsidiaries. At March 31, 2017, our subsidiaries had total liabilities of approximately $26 billion to non-affiliated third parties. In addition, at March 31, 2017, our subsidiaries had approximately $108 million of liabilities owed to us. See “Description of Debt Securities—Holding Company Structure” in the accompanying prospectus.

Optional Redemption

We will be entitled to redeem the notes at our option as described below.

Prior to                 , 2027 (the “Par Call Date”), we may at our option redeem the notes, at any time in whole or from time to time in part, at a redemption price for any redemption date equal to the greater of the following amounts:

• 100% of the principal amount of the notes being redeemed on that redemption date; or

S-6

• the sum of the present values of the remaining scheduled payments of principal and interest on the notes being redeemed on that redemption date (not including any portion of any payments of interest accrued to the redemption date) that would be due if the notes matured, and accrued and unpaid interest was payable, on the Par Call Date, discounted to that redemption date on a semi-annual basis at the Adjusted Treasury Rate (as defined below) plus         basis points, as determined by the Independent Investment Banker (as defined below),

plus, in each case, accrued and unpaid interest on the notes to be redeemed to the redemption date.

On and after the Par Call Date, we may at our option redeem the notes, at any time in whole or from time to time in part, at a redemption price equal to 100% of the principal amount of the notes to be redeemed, plus accrued and unpaid interest on the notes to be redeemed to the redemption date.

Notwithstanding the foregoing, installments of interest on the notes that are due and payable on any interest payment date falling on or prior to a redemption date for the notes will be payable on that interest payment date to the registered holders thereof as of the close of business on the relevant record date according to the terms of the notes and the indenture. The redemption price will, if applicable, be calculated on the basis of a 360-day year consisting of twelve 30-day months.

“Adjusted Treasury Rate” means, with respect to any redemption date for the notes, the rate per annum equal to the semi-annual equivalent yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such redemption date.

“Comparable Treasury Issue” means, with respect to any redemption date for the notes, the United States Treasury security selected by the Independent Investment Banker as having an actual or interpolated maturity comparable to the remaining term of the notes to be redeemed on such redemption date (assuming the notes matured on the Par Call Date) 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 the notes (assuming the notes matured on the Par Call Date).

“Comparable Treasury Price” means, with respect to any redemption date for the notes, (A) the average of the Reference Treasury Dealer Quotations for such redemption date or (B) if only one Reference Treasury Dealer Quotation is received, such quotation.

“Independent Investment Banker” means, with respect to any redemption date for the notes, one of the Reference Treasury Dealers appointed by us to act as the “Independent Investment Banker.”

“Reference Treasury Dealers” mean, with respect to any redemption date for the notes, (A) Citigroup Global Markets Inc., RBC Capital Markets, LLC and Wells Fargo Securities, LLC (or their respective affiliates which are Primary Treasury Dealers (as defined below)), and their respective successors; provided, however, that if any of the foregoing shall cease to be a primary U.S. Government securities dealer in the United States (a “Primary Treasury Dealer”), we will substitute therefor another Primary Treasury Dealer; (B) one Primary Treasury Dealer selected by U.S. Bancorp Investments, Inc. and its successors; and (C) any other Primary Treasury Dealer(s) selected by us.

“Reference Treasury Dealer Quotation” means, with respect to each Reference Treasury Dealer and any redemption date for the notes, the average, as determined by us, 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 us by such Reference Treasury Dealer at 5:00 p.m. (New York City time) on the third business day preceding such redemption date. As used in the preceding sentence, “business day” means any day (other than a Saturday or Sunday) on which banking institutions in The City of New York are not authorized or obligated by law or executive order to remain closed.

S-7

We will mail notice of any redemption at least 30 days but not more than 60 days before the redemption date to each registered holder of the notes to be redeemed. Once notice of redemption is mailed, the notes called for redemption will become due and payable on the redemption date at the applicable redemption price, plus accrued and unpaid interest to the redemption date, and will be paid upon surrender thereof for redemption. If only part of a note is redeemed, the trustee will deliver a new note in a principal amount equal to the unredeemed portion of the principal of the note surrendered for redemption. If we elect to redeem all or a portion of the notes, that redemption will not be conditional upon receipt by the paying agent or the trustee of monies sufficient to pay the redemption price.

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

Events of Default

An “event of default” occurs with respect to the notes if:

(a) we do not pay any interest on any note within 30 days of the due date;

(b) we do not pay any principal of or premium, if any, on any note on the due date;

(c) we remain in breach of any other covenant or warranty (excluding covenants and warranties solely applicable to another series of debt securities issued under the indenture) in the indenture or the notes for 60 days after we are given a written notice of default specifying such breach and requiring remedy of the breach; the notice must be sent by either the trustee or registered holders of at least 25% of the principal amount of the outstanding notes; or

(d) we file for bankruptcy or other specified events of bankruptcy, insolvency, receivership or reorganization of us occur.

No event of default with respect to the notes necessarily constitutes an event of default with respect to the debt securities of any other series issued under the indenture.

The terms of approximately $1.75 billion aggregate principal amount of outstanding senior debt securities that we previously issued under the indenture (the “prior debt securities”) include a so-called “cross-default” event of default, which would occur, in general, upon our failure to pay when due, or the acceleration of, certain threshold amounts of our debt. The prior debt securities with a “cross default” event of default have a threshold amount of at least $25 million. The notes offered hereby do not include a cross-default event of default. Accordingly, the principal of and interest on the prior debt securities may be declared due and payable immediately upon the occurrence of a cross-default event of default, while the holders of the notes will not be entitled to accelerate the notes as a result of such event.

Other

The notes will not be subject to a sinking fund or entitled to any guarantees and you will not be permitted to require us to redeem or repurchase the notes at your option.

We will pay principal of and premium, if any, on the notes at stated maturity, upon redemption or otherwise, upon presentation of the notes at the office of the trustee, as our paying agent. In our discretion, we may appoint one or more additional paying agents and security registrars and designate one or more additional places for payment and for registration of transfer, but we must at all times maintain a place of payment of the notes and a place for registration of transfer of the notes in the Borough of Manhattan, The City of New York.

We may, from time to time, without notice to or the consent of the holders of the notes, increase the principal amount of the notes under the indenture and issue such increased principal amount (or any portion thereof), in which case any additional notes so issued shall have the same form and terms (other than offering

S-8

price, the date of issuance and, under certain circumstances, the date from which interest thereon shall begin to accrue and the first interest payment date), and shall carry the same right to receive accrued and unpaid interest, as the notes previously issued and such additional notes shall form a single series with the notes offered by this prospectus supplement, provided that such additional notes shall be fungible with the notes offered by this prospectus supplement for United States federal income tax purposes.

The notes initially will be issued in book-entry form and represented by one or more global securities deposited with, or on behalf of, The Depository Trust Company, as Depositary, and registered in the name of Cede & Co., its nominee. This means that you will not be entitled to receive a certificate for the notes that you purchase except in limited circumstances set forth in the indenture. The notes will be issued only in fully registered form without coupons, in denominations of $2,000 and integral multiples of $1,000 in excess thereof. We expect that payments due on notes in book-entry form will be paid by wire transfer of funds to the Depositary or its nominee.

S-9

MATERIAL UNITED STATES FEDERAL TAX CONSIDERATIONS

The following is a summary of certain material United States federal income tax considerations relating to the purchase, ownership and disposition of the notes, but does not purport to be a complete analysis of all the potential tax considerations relating thereto. This summary is based upon the provisions of the Internal Revenue Code of 1986, as amended (the “Code”), Treasury Regulations promulgated thereunder, administrative rulings and judicial decisions, each as of the date hereof. These authorities may be changed, perhaps retroactively, so as to result in United States federal income tax consequences different from those set forth below. We have not sought any ruling from the Internal Revenue Service (the “IRS”) or an opinion of counsel with respect to the statements made and the conclusions reached in the following summary, and there can be no assurance that the IRS will agree with such statements and conclusions.

This summary is limited to holders who purchase the notes upon their initial issuance at their initial issue price (which will equal the first price at which a substantial amount of notes is sold to the public for cash) and who hold the notes as capital assets (generally, property held for investment). This summary does not address United States federal tax laws other than income tax laws, and it does not address tax considerations arising under the laws of any foreign, state or local jurisdiction. In addition, this discussion does not address all tax considerations that may be applicable to a holder’s particular circumstances or to holders that may be subject to special tax rules, including, without limitation:

• holders subject to the alternative minimum tax;

• banks, insurance companies or other financial institutions;

• tax-exempt organizations;

• regulated investment companies or real estate investment trusts;

• dealers in securities or commodities;

• traders in securities that elect to use a mark-to-market method of accounting for their securities holdings;

• foreign persons or entities (except to the extent specifically set forth below);

• S-corporations, partnerships or other pass-through entities;

• expatriates and certain former citizens or long-term residents of the United States;

• “U.S. holders” (as defined below) whose “functional currency” is not the United States dollar;

• persons who hold the notes as a position in a hedging transaction, “straddle,” “conversion transaction” or other risk reduction transaction; or

• persons deemed to sell the notes under the constructive sale provisions of the Code.

If a partnership (or other entity taxable as a partnership for United States federal income tax purposes) holds notes, the tax treatment of a partner in the partnership generally will depend upon the status of the partner and the activities of the partnership. If you are a partner in a partnership holding our notes, you should consult your tax advisor regarding the tax consequences of the purchase, ownership and disposition of the notes.

THIS SUMMARY OF CERTAIN MATERIAL UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS IS FOR GENERAL INFORMATION ONLY AND IS NOT TAX ADVICE. YOU ARE URGED TO CONSULT YOUR TAX ADVISOR WITH RESPECT TO THE APPLICATION OF UNITED STATES FEDERAL INCOME TAX LAWS TO YOUR PARTICULAR SITUATION AS WELL AS ANY TAX CONSEQUENCES OF THE PURCHASE, OWNERSHIP AND DISPOSITION OF THE NOTES ARISING UNDER OTHER UNITED STATES FEDERAL TAX RULES OR UNDER THE LAWS OF ANY STATE, LOCAL, FOREIGN OR OTHER TAXING JURISDICTION OR UNDER ANY APPLICABLE TAX TREATY.

S-10

Consequences to U.S. Holders

The following is a summary of certain material United States federal income tax consequences that will apply to you if you are a U.S. holder (as defined below) of the notes. Certain consequences to non-U.S. holders (as defined below) of the notes are described under “—Consequences to Non-U.S. Holders” below. The term “U.S. holder” means a beneficial owner of a note that is:

• an individual who is a citizen or resident of the United States;

• a corporation (or other entity taxable as a corporation for United States federal income tax purposes) created or organized in or under the laws of the United States or of any state thereof or the District of Columbia;

• an estate the income of which is subject to United States federal income taxation regardless of its source; or

• a trust that (i) is subject to the primary supervision of a United States court and the control of one or more United States persons or (ii) has a valid election in effect under applicable Treasury Regulations to be treated as a United States person.

Payments of Interest

You generally will be required to recognize any stated interest as ordinary income at the time it is paid or accrued on the notes in accordance with your regular method of accounting for United States federal income tax purposes.

Sale, Exchange, Redemption or Other Taxable Disposition of Notes

You generally will recognize capital gain or loss upon the sale, exchange, redemption or other taxable disposition of a note in an amount equal to the difference between (i) the sum of cash plus the fair market value of all other property received on such disposition (except to the extent such cash or property is attributable to accrued but unpaid interest not previously included in income, which generally will be taxable as ordinary income) and (ii) your adjusted tax basis in the note. Your adjusted tax basis in a note generally will equal the amount you paid for the note. Under current law, if you are a non-corporate U.S. holder, including an individual, and have held the note for more than one year at the time of disposition, such capital gain generally will be subject to tax at a maximum rate of 20%. Your ability to deduct capital losses may be limited.

Backup Withholding and Information Reporting

Payments of interest and principal on notes held by U.S. holders and the proceeds received upon the sale, exchange, redemption or other disposition of such notes may be subject to information reporting and backup withholding. Payments to certain holders (including, among others, certain tax-exempt organizations) are generally not subject to information reporting or backup withholding. If you are a U.S. holder and you are not otherwise exempt, payments to you will be subject to backup withholding if:

• you fail to furnish your taxpayer identification number (“TIN”), which, for an individual, is ordinarily his or her social security number, in the manner required by the Code and applicable Treasury Regulations;

• we or our agent (or other payor) are notified by the IRS that the TIN you furnished is incorrect;

• there has been a “notified payee underreporting” with respect to interest or dividends paid to you, as described in the Code; or

• you have failed to certify under penalty of perjury that you have furnished a correct TIN and that you are not subject to backup withholding under the Code.

S-11

You should consult your tax advisor regarding your qualification for an exemption from backup withholding and information reporting and the procedures for obtaining such an exemption, if applicable. Backup withholding is not an additional tax, and you may use amounts withheld under the backup withholding rules as a credit against your United States federal income tax liability or may claim a refund as long as you provide the required information to the IRS in a timely manner.

Net Investment Income

A 3.8% tax will be imposed on a portion or all of the net investment income of certain individuals with a modified adjusted gross income of over $200,000 ($250,000 in the case of joint filers) and on the undistributed net investment income of certain estates and trusts. Among other items, net investment income generally includes gross income from interest and net gain attributable to the disposition of certain property, such as the notes, less certain deductions. U.S. holders should consult their own tax advisors regarding the possible implications of this tax to their particular circumstances.

Consequences to Non-U.S. Holders

The following is a summary of certain material United States federal income tax consequences that will apply to you if you are a non-U.S. holder of notes. The term “non-U.S. holder” means a beneficial owner of a note that is not a partnership (or other entity taxable as a partnership for United States federal income tax purposes) or a U.S. holder.

Special rules may apply to certain non-U.S. holders such as “controlled foreign corporations” and “passive foreign investment companies.” Such entities should consult their tax advisors to determine the United States federal, state, local and other tax consequences that may be relevant to them.

Payments of Interest

Subject to the discussion of backup withholding and information reporting and FATCA below, United States federal withholding tax will not apply to any payment to you of interest on a note provided that such interest is not effectively connected with your conduct of a United States trade or business and:

• you do not own, actually or constructively, 10% or more of the total combined voting power of all classes of our stock entitled to vote;

• you are not a “controlled foreign corporation” with respect to which we are, directly or indirectly, a “related person”;

• you are not a bank receiving interest pursuant to a loan agreement entered into in the ordinary course of your trade or business; and

• (a) you provide your name and address, and certify, under penalties of perjury, that you are not a United States person (which certification may be made on an IRS Form W-8BEN or IRS Form W-8BEN-E, as applicable (or substitute Form W-8BEN or Form W-8BEN-E, or the appropriate successor form for either form)) or (b) a securities clearing organization, bank, or other financial institution that holds customers’ securities in the ordinary course of its business holds the note on your behalf and certifies, under penalties of perjury, that it has received IRS Form W-8BEN or IRS Form W-8BEN-E, as applicable (or substitute Form W-8BEN or Form W-8BEN-E, or the appropriate successor form for either form), from you or from another qualifying financial institution intermediary, and, in certain circumstances, provides a copy of the IRS Form W-8BEN or IRS Form W-8BEN-E, as applicable (or substitute Form W-8BEN or Form W-8BEN-E, or the appropriate successor form for either form). If you hold your notes through certain foreign intermediaries or certain foreign partnerships, such foreign intermediaries or partnerships must also satisfy the certification requirements of applicable Treasury Regulations.

S-12

If you cannot satisfy the requirements described above, you will be subject to a 30% United States federal withholding tax with respect to payments of interest on the notes, unless you provide us with a properly executed (1) IRS Form W-8BEN or IRS Form W-8BEN-E, as applicable (or substitute Form W-8BEN or Form W-8BEN-E, or the appropriate successor form for either form) claiming an exemption from or reduction in withholding under the benefit of an applicable United States income tax treaty or (2) IRS Form W-8ECI (or successor form) stating that the interest paid on the note is not subject to withholding tax because it is effectively connected with your conduct of a trade or business in the United States.

If you are engaged in a trade or business in the United States and interest on a note is effectively connected with your conduct of that trade or business (and, if an income tax treaty applies, such interest is attributable to a permanent establishment maintained by you in the United States), you will be subject to United States federal income tax on that interest on a net income basis (although you will be exempt from the 30% withholding tax, provided the certification requirements described above are satisfied) in the same manner as if you were a United States person as defined under the Code. In addition, if you are a foreign corporation, you may be subject to a branch profits tax equal to 30% (or lower applicable treaty rate) of your earnings and profits for the taxable year, subject to adjustments, that are effectively connected with your conduct of a trade or business in the United States. For this purpose, interest will be included in the earnings and profits of such foreign corporation.

Sale, Exchange, Redemption or Other Taxable Disposition of Notes

Subject to the discussion of backup withholding and information reporting and FATCA below, any gain realized upon the sale, exchange, redemption or other taxable disposition of a note (other than any amount allocable to accrued and unpaid interest, which will be taxable as interest and may be subject to the rules discussed above in “—Consequences to Non-U.S. Holders—Payments of Interest”) generally will not be subject to United States federal income tax unless:

• that gain is effectively connected with your conduct of a trade or business in the United States (and, if an income tax treaty applies, such gain is attributable to a permanent establishment maintained by you in the United States); or

• you are an individual who is present in the United States for 183 days or more in the taxable year of that disposition, and certain other conditions are met.

If your gain is effectively connected with your conduct of a United States trade or business (and, if an income tax treaty applies, such gain is attributable to a permanent establishment maintained by you in the United States), you generally will be subject to United States federal income tax on the net gain derived from the sale, exchange, redemption or other disposition in the same manner as if you were a United States person (as defined under the Code). If you are a corporation, any such effectively connected gain received by you may also, under certain circumstances, be subject to the branch profits tax at a 30% rate (or such lower rate as may be prescribed under an applicable United States income tax treaty). If you are described in the second bullet point above, you will be subject to United States federal income tax on the gain derived from the sale, exchange, redemption or other disposition at a 30% rate (or such lower rate as may be prescribed under an applicable United States income tax treaty), which gain may be offset by United States source capital losses, even though you are not considered a resident of the United States.

Backup Withholding and Information Reporting

If you are a non-U.S. holder, you will generally not be subject to backup withholding and information reporting with respect to payments that we make to you, or with respect to the proceeds of the sale of a note within the United States or conducted through certain United States-related financial intermediaries, if the payor receives the statement described above under “—Consequences to Non-U.S. Holders—Payments of Interest” and does not have actual knowledge or reason to know that you are a United States person, as defined under the Code, or you otherwise establish an exemption. However, we may be required to report annually to the IRS and

S-13

to you the amount of, and the tax withheld with respect to, any interest paid to you, regardless of whether any tax was actually withheld. Copies of these information returns may also be made available under the provisions of a specific treaty or agreement to the tax authorities of the country in which you reside.

You generally will be entitled to credit any amounts withheld under the backup withholding rules against your United States federal income tax liability provided that the required information is furnished to the IRS in a timely manner.

Foreign Account Tax Compliance Act

Pursuant to legislation commonly referred to as “FATCA” and regulations promulgated thereunder, payments to foreign entities of interest on and the gross proceeds of dispositions of debt obligations of a U.S. issuer will be subject to a withholding tax (separate and apart from, but without duplication of, the withholding tax described above) at a rate of 30%, unless various U.S. information reporting and due diligence requirements (generally relating to ownership by U.S. persons of interests in or accounts with those entities) have been satisfied. FATCA currently applies to payments of interest on the notes and will apply to payments of gross proceeds of a sale or other disposition of notes occurring on or after January 1, 2019. You should consult your tax advisor regarding the possible effect of FATCA on your investment in the notes.

UNDERWRITING (CONFLICTS OF INTEREST)

Citigroup Global Markets Inc., RBC Capital Markets, LLC, U.S. Bancorp Investments, Inc. and Wells Fargo Securities, LLC are acting as representatives of the underwriters named below.

Subject to the terms and conditions stated in the underwriting agreement dated the date of this prospectus supplement, each underwriter named below has severally agreed to purchase, and we have agreed to sell to that underwriter, the principal amount of notes set forth opposite the underwriter’s name.

Name	Principal Amount of Notes
Citigroup Global Markets Inc.	$
RBC Capital Markets, LLC
U.S. Bancorp Investments, Inc.
Wells Fargo Securities, LLC
Total	$

The underwriting agreement provides that the obligations of the several underwriters to purchase the notes included in this offering are subject to approval of certain legal matters by counsel and to other conditions. The underwriters are obligated to purchase all the notes if they purchase any of the notes. The offering of the notes by the underwriters is subject to receipt and acceptance and to the underwriters’ right to reject any order in whole or in part.

The underwriters propose to offer the notes directly to the public initially at the public offering price set forth on the cover page of this prospectus supplement. Notes sold by the underwriters to dealers may be sold at the public offering price less a concession not to exceed     % of the principal amount of the notes. The underwriters may allow, and dealers may reallow, a concession not to exceed     % of the principal amount of the notes on sales to other dealers. After the initial offering of the notes to the public, the representatives may change the public offering price and concessions.

The notes are a new issue of securities with no established trading market. There can be no assurance of a secondary market for the notes or the continued liquidity of such market if one develops. It is not anticipated that the notes will be listed on any securities exchange.

The following table shows the underwriting discount that we are to pay to the underwriters in connection with this offering (expressed as a percentage of the principal amount of the notes).

	Paid by Sempra Energy
Per note		%

In connection with the offering, the representatives, on behalf of the underwriters, may purchase and sell notes in the open market. These transactions may include over-allotment, syndicate covering transactions and stabilizing transactions. Over-allotment involves syndicate sales of notes in excess of the principal amount of notes to be purchased from us by the underwriters in the offering, which creates a syndicate short position. Syndicate covering transactions involve purchases of the notes in the open market after the distribution has been completed in order to cover syndicate short positions. Stabilizing transactions consist of certain bids or purchases of notes made for the purpose of preventing or retarding a decline in the market prices of the notes while the offering is in progress.

S-15

The underwriters also may impose a penalty bid. Penalty bids permit the underwriters to reclaim a selling concession from a syndicate member when the representatives, in covering syndicate short positions or making stabilizing purchases, repurchase notes originally sold by that syndicate member.

Any of these activities may have the effect of preventing or retarding a decline in the market prices of the notes. They may also cause the prices of the notes to be higher than the prices that otherwise would exist in the open market in the absence of these transactions. The underwriters may conduct these transactions in the over-the-counter market or otherwise. If the underwriters commence any of these transactions, they may discontinue them at any time.

We estimate that our total expenses for this offering, excluding the underwriting discount, will be approximately $1,000,000.

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. Some or all of the underwriters and/or their affiliates have acted and/or are acting as lenders to, and/or have from time to time performed and/or are performing certain investment banking, advisory, general financing, trustee and commercial banking and other commercial transactions and services for, us and/or our affiliates for which they have received and in the future may receive customary fees and expenses. The underwriters and their affiliates may, from time to time, engage in other transactions with or perform other services for us and our affiliates in the ordinary course of their business for which they receive customary fees and expenses.

In addition, in the ordinary course of their business activities, the underwriters and their respective 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, and such investment and securities activities may involve securities and/or instruments of ours or our affiliates. If any of the underwriters or their affiliates has a lending relationship with us, certain of those underwriters or their affiliates routinely hedge and certain other of those underwriters or their affiliates may hedge, their credit exposure to us consistent with their customary risk management policies. Typically, these underwriters and their affiliates would hedge such exposure by entering into transactions which may consist of either the purchase of credit default swaps or the creation of short positions in our securities, including potentially the notes offered hereby. Any such credit default swaps or short positions could adversely affect future trading prices of the notes 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.

We have agreed to indemnify the several underwriters against certain liabilities, including liabilities under the Securities Act of 1933, as amended, or to contribute to payments the underwriters may be required to make because of any of those liabilities.

Conflicts of Interest

As described in this prospectus supplement under “Use of Proceeds,” net proceeds of this offering will be used to repay outstanding commercial paper. One or more of the underwriters participating in this offering and/or their affiliates may hold positions in our commercial paper, and one or more of the underwriters may act as dealers under our commercial paper programs. To the extent that net proceeds from this offering are applied to repay our commercial paper held by any of the underwriters or their affiliates, they will receive proceeds of this offering through the repayment of that commercial paper. If 5% or more of the net proceeds of this offering (not including the underwriting discount) is used to repay our outstanding commercial paper held by at least one of the underwriters or their affiliates, this offering will be conducted in accordance with FINRA Rule 5121. In such

S-16

event, such underwriter or underwriters will not confirm sales of the notes to accounts over which they exercise discretionary authority without the prior written approval of the customer.

DESCRIPTION OF DEBT SECURITIES

Unless indicated differently in a prospectus supplement, the following description sets forth the general terms and provisions of the debt securities that Sempra Energy may offer by this prospectus. The debt securities may be issued as senior debt securities or subordinated debt securities.

The senior debt securities will be governed by the senior indenture and the subordinated debt securities will be governed by the subordinated indenture. Each indenture gives the issuer broad authority to set the particular terms of each series of debt securities, including the right to modify certain of the terms contained in the indenture. The particular terms of a series of debt securities and the extent, if any, to which the particular terms of the issue modify the terms of the applicable indenture will be described in the accompanying prospectus supplement relating to such series of debt securities.

Each indenture contains the full legal text of the matters described in this section. Because this section is a summary, it does not describe every aspect of the debt securities or the applicable indentures. This summary is subject to and qualified in its entirety by reference to all the provisions of the applicable indenture, including definitions of terms used in such indenture. We also include references in parentheses to certain sections of the indenture. Whenever we refer to particular sections or defined terms of the indentures in this prospectus or in a prospectus supplement, these sections or defined terms are incorporated by reference into this prospectus or into the prospectus supplement. This summary also is subject to and qualified by reference to the description of the particular terms of a particular series of debt securities described in the applicable prospectus supplement or supplements.

General

Sempra Energy may issue an unlimited amount of debt securities under the indentures in one or more series. Sempra Energy is not required to issue all debt securities of one series at the same time and, unless otherwise provided in a prospectus supplement, may reopen a series, without the consent of the holders of the debt securities of that series, for issuances of additional debt securities of that series.

The debt securities of Sempra Energy will be its unsecured obligations.

Before the issuance of each series of debt securities, the terms of the particular securities will be specified in either a supplemental indenture (including any pricing supplement) and a board resolution of Sempra Energy or in one or more officers’ certificates of Sempra Energy pursuant to a supplemental indenture or a board resolution. We refer you to the applicable prospectus supplement for a description of the following terms of each series of debt securities:

(a) the title of the debt securities;

(b) any limit upon the aggregate principal amount of the debt securities;

(c) the person to whom any interest on a security of the series shall be payable, if other than the person in whose name that security is registered;

(d) the date or dates on which principal will be payable or how to determine the dates;

(e) the rate or rates or method of determination of interest; the date or dates from which interest will accrue; the dates on which interest will be payable, which we refer to as the “interest payment dates”; and any record dates for the interest payable on the interest payment dates;

(f) the right, if any, to extend the interest payment periods, and the terms of any such extensions;

(g) the place or places where principal of and any premium and interest on the debt securities will be payable and whether, if acceptable to the trustee, any principal of such securities will be payable without presentation or surrender thereof;

9

(h) the period or periods within which, or the date or dates on which, the price or prices at which and the terms and conditions upon which Sempra Energy may redeem the debt securities, in whole or in part, and the manner in which any election by Sempra Energy to redeem the debt securities shall be evidenced;

(i) any obligation of Sempra Energy to redeem or purchase debt securities pursuant to any sinking fund, purchase fund or similar provision, or any option of the registered holder to require us to redeem or purchase debt securities, and the terms and conditions upon which the debt securities will be redeemed or purchased, in whole or in part;

(j) the denominations in which the debt securities will be issuable (if other than denominations of $1,000 and any integral multiple thereof);

(k) whether the amount of principal or any premium or interest on any debt securities may be determined with reference to an index or pursuant to a formula and the manner in which such amounts will be determined;

(l) the currency, currencies or currency units in which the principal of and any premium or interest on the debt securities will be payable, if other than United States dollars, and the manner of determining the equivalent thereof in United States dollars;

(m) if at the election of Sempra Energy or the holder, the payments of principal of or any premium or interest on the debt securities will be payable in one or more currencies or currency units other than those in which the debt securities are stated to be payable, the terms and conditions upon which such election is to be made and the manner in which such amounts shall be determined;

(n) the portion of the principal amount of the debt securities that will be payable upon declaration of acceleration of the maturity date, if other than the entire principal amount;

(o) the amount which will be deemed to be the principal amount of the debt securities as of any date or dates before the stated maturity date, if the principal amount will not be determinable as of any such date or dates prior to the stated maturity date, including the amount which will be due and payable or outstanding as of any such date;

(p) whether the sections of the indenture providing for defeasance do not apply to any debt securities;

(q) whether the debt securities are to be issued in whole or in part in the form of one or more global debt securities and, if so, the identity of the depositary for the global debt securities;

(r) any addition, modification or deletion of any Events of Default or covenants provided in the indenture with respect to debt securities and any change in the acceleration provisions with respect to the debt securities;

(s) any addition to or change in the covenants set forth in the indenture with respect to the debt securities; and

(t) any other terms of the debt securities.

(See Section 301.)

Ranking

The senior debt securities will be the unsecured and unsubordinated obligations of Sempra Energy. The indebtedness represented by the senior debt securities will rank equally with all other unsecured and unsubordinated debt of the company. The indebtedness represented by the subordinated debt securities will rank junior and subordinate in right of payment to the prior payment in full of the senior debt of Sempra Energy, to the extent and in the manner set forth under the caption “—Subordination” below and as may be set forth in a prospectus supplement. The debt securities are obligations of Sempra Energy exclusively, and are not the

10

obligations of any of its subsidiaries. Because Sempra Energy conducts its operations primarily through its subsidiaries and substantially all of its consolidated assets are held by its subsidiaries, the debt securities will be effectively subordinated to all existing and future indebtedness and other liabilities of Sempra Energy’s subsidiaries.

Holding Company Structure

Sempra Energy conducts its operations primarily through its subsidiaries and substantially all of its consolidated assets are held by its subsidiaries. Accordingly, Sempra Energy’s cash flow and its ability to meet its obligations under its debt securities are largely dependent upon the earnings of its subsidiaries and the distribution or other payment of these earnings to Sempra Energy in the form of dividends or loans or advances and repayment of loans and advances from Sempra Energy. The subsidiaries are separate and distinct legal entities and have no obligation to pay any amounts due on the Sempra Energy debt securities or to make any funds available for payment of amounts due on these debt securities.

Because Sempra Energy is a holding company, its obligations under the debt securities will be structurally subordinated to all existing and future liabilities of its subsidiaries. Therefore, Sempra Energy’s rights and the rights of its creditors, including the rights of the holders of the debt securities issued by Sempra Energy, to participate in the assets of any subsidiary upon the liquidation or reorganization of the subsidiary will be subject to the prior claims of the subsidiary’s creditors. To the extent that Sempra Energy may itself be a creditor with recognized claims against any of its subsidiaries, Sempra Energy’s claims would still be effectively subordinated to any security interest in, or mortgages or other liens on, the assets of the subsidiary and would be subordinated to any indebtedness or other liabilities of the subsidiary that are senior to the claims held by Sempra Energy. Sempra Energy expects to incur, and expects that its subsidiaries will incur, substantial additional amounts of indebtedness.

Payment of Debt Securities—Interest

Unless indicated differently in a prospectus supplement, Sempra Energy will pay interest on the debt securities on each interest payment date by check mailed, or by wire transfer at such place and to such account at a banking institution in the United States as may be designated in writing to the Trustee at least 15 days prior to the date for payment, to the person in whose name the debt securities are registered as of the close of business on the regular record date relating to the interest payment date.

However, if we default in paying interest on a debt security, we will pay defaulted interest in either of the two following ways:

(a) We will first propose to the trustee a payment date for the defaulted interest. Next, the trustee will choose a special record date for determining which registered holders are entitled to the payment. The special record date will be between ten and 15 days before the proposed payment date. Finally, we will pay the defaulted interest on the payment date to the registered holder of the debt security as of the close of business on the special record date.

(b) Alternatively, we can propose to the trustee any other lawful manner of payment that is consistent with the requirements of any securities exchange on which the debt securities are listed for trading. If the trustee thinks the proposal is practicable, payment will be made as proposed.

(See Section 307.)

Payment of Debt Securities—Principal

Sempra Energy will pay principal of and any premium and interest on the debt securities at stated maturity, upon redemption or otherwise, upon presentation of the debt securities at the office of the paying agent, which

11

initially will be the trustee or such other paying agent designated in accordance with the applicable indenture. Any other paying agent initially designated for the debt securities of a particular series will be named in the applicable prospectus supplement.

If any interest payment date, redemption date or the maturity date of the debt securities is not a business day at any place of payment, then payment of the principal, premium, if any, and interest may be made on the next business day at that place of payment. In that case, no interest will accrue on the amount payable for the period from and after the applicable interest payment date, redemption date or maturity date, as the case may be.

Sempra Energy will pay principal of and any premium on the debt securities at stated maturity, upon redemption or otherwise, upon presentation of the debt securities at the office of the paying agent. In its discretion, Sempra Energy may appoint one or more additional paying agents and security registrars and designate one or more additional places for payment and for registration of transfer, but must at all times maintain a place of payment of the debt securities and a place for registration of transfer of the debt securities in the Borough of Manhattan, the City of New York. (See Section 1002.)

Form; Transfers; Exchanges

The debt securities will be issued:

(a) only in fully registered form;

(b) without interest coupons; and

(c) in denominations that are even multiples of $1,000.

You may have your debt securities divided into debt securities of smaller denominations (of at least $1,000) or combined into debt securities of larger denominations, as long as the total principal amount is not changed. This is called an “exchange.” (See Section 305.)

You may exchange or transfer debt securities at the office of the trustee. The trustee acts as our agent for registering debt securities in the names of holders and transferring debt securities. Sempra Energy may appoint another agent or act as its own agent for this purpose. The entity performing the role of maintaining the list of registered holders is called the “security registrar.” It will also perform transfers. (See Section 305.)

In our discretion, we may change the place for registration of transfer of the debt securities and may remove and/or appoint one or more additional security registrars. (See Sections 305 and 1002.)

There will be no service charge for any transfer or exchange of the debt securities, but you may be required to pay a sum sufficient to cover any tax or other governmental charge payable in connection with the transfer or exchange.

We may block the transfer or exchange of (a) debt securities during a period of 15 days before giving any notice of redemption or (b) any debt security selected for redemption in whole or in part, except the unredeemed portion of any debt security being redeemed in part. (See Section 305.)

Events of Default

An “event of default” occurs with respect to the debt securities of any series if:

(a) Sempra Energy does not pay any interest on any debt securities of the applicable series within 30 days of the due date;

(b) Sempra Energy does not pay any principal of or premium on any debt securities of the applicable series on the due date;

12

(c) Sempra Energy does not make a sinking fund payment with respect to any debt securities of the applicable series when due;

(d) Sempra Energy remains in breach of a covenant or warranty (excluding covenants and warranties solely applicable to another series of debt securities issued under the applicable indenture) in the applicable indenture or the debt securities of the applicable series for 60 days after it receives, by registered or certified mail, a written notice of default specifying such default or breach and requiring remedy of the default or breach; the notice must be sent by either the trustee or registered holders of at least 25% of the principal amount of the outstanding debt securities of that series;

(e) default occurs under any bond, note, debenture or other instrument evidencing any indebtedness for money borrowed by Sempra Energy, excluding any of its subsidiaries (including a default with respect to any other series of debt securities issued under the applicable indenture), or under any mortgage, indenture or other instrument under which there may be issued or by which there may be secured or evidenced any indebtedness for money borrowed by Sempra Energy (or the payment of which is guaranteed by Sempra Energy), excluding any of its subsidiaries, whether such indebtedness or guarantee exists on the date of the applicable indenture or is issued or entered into following the date of the applicable indenture, if:

(1) either:

• such default results from the failure to pay any such indebtedness when due; or

• as a result of such default the maturity of such indebtedness has been accelerated prior to its expressed maturity; and

(2) the principal amount of such indebtedness, together with the principal amount of any other such indebtedness in default for failure to pay any such indebtedness when due or the maturity of which has been so accelerated, aggregates at least $25 million;

(f) Sempra Energy (excluding any of its subsidiaries) files for bankruptcy, or other specified events in bankruptcy, insolvency, receivership or reorganization occur with respect to Sempra Energy (excluding any of its subsidiaries); or

(g) any other event of default specified in the applicable prospectus supplement for such series occurs.

(See Section 501.)

No event of default with respect to a series of debt securities necessarily constitutes an event of default with respect to the debt securities of any other series issued under the applicable indenture.

Remedies

Acceleration

If an event of default occurs and is continuing with respect to any series of debt securities, then either the trustee or the registered holders of at least 25% in principal amount of the outstanding debt securities of that series may declare the principal amount of all of the debt securities of that series, together with accrued and unpaid interest thereon, to be due and payable immediately. (See Section 502.)

13

Rescission of Acceleration

After the declaration of acceleration has been made with respect to any series of debt securities and before the trustee has obtained a judgment or decree for payment of the money due, the declaration and its consequences will be rescinded and annulled, if:

(a) Sempra Energy pays or deposits with the trustee a sum sufficient to pay:

(1) all overdue interest on the debt securities of that series, other than interest which has become due by declaration of acceleration;

(2) the principal of and any premium on the debt securities of that series which have become due, otherwise than by the declaration of acceleration, and overdue interest on these amounts;

(3) interest on overdue interest, other than interest which has become due by declaration of acceleration, on the debt securities of that series to the extent lawful; and

(4) all amounts due to the trustee under the applicable indenture; and

(b) all events of default with respect to the debt securities of that series, other than the nonpayment of the principal and interest which has become due solely by the declaration of acceleration, have been cured or waived as provided in the applicable indenture.

(See Section 502.)

For more information as to waiver of defaults, see “—Waiver of Default and of Compliance” below.

Control by Registered Holders; Limitations

If an event of default with respect to the debt securities of any series occurs and is continuing, the registered holders of a majority in principal amount of the outstanding debt securities of that series, voting as a single class, without regard to the holders of outstanding debt securities of any other series that may also be in default, will have the right to direct the time, method and place of:

(a) conducting any proceeding for any remedy available to the trustee with respect to the debt securities of that series; and

(b) exercising any trust or power conferred on the trustee with respect to the debt securities of that series.

These rights of registered holders to give directions are subject to the following limitations:

(a) the registered holders’ directions do not conflict with any law or the applicable indenture; and

(b) the direction is not unduly prejudicial to the rights of holders of the debt securities of that series who do not join in that action.

The trustee may also take any other action it deems proper which is consistent with the registered holders’ direction. (See Sections 512 and 603.)

In addition, each indenture provides that no registered holder of debt securities of any series will have any right to institute any proceeding, judicial or otherwise, with respect to the applicable indenture or for the appointment of a receiver or for any other remedy thereunder unless:

(a) that registered holder has previously given the trustee written notice of a continuing event of default;

(b) the registered holders of at least 25% in aggregate principal amount of the outstanding debt securities of that series have made written request to the trustee to institute proceedings in respect of that event of default and have offered the trustee reasonable indemnity against costs and liabilities incurred in complying with the request; and

14

(c) for 60 days after receipt of the notice, the trustee has failed to institute a proceeding and no direction inconsistent with the request has been given to the trustee during the 60-day period by the registered holders of a majority in aggregate principal amount of outstanding debt securities of that series.

Furthermore, no registered holder will be entitled to institute any action if and to the extent that the action would disturb or prejudice the rights of other registered holders of debt securities. (See Section 507.)

However, each registered holder has an absolute and unconditional right to receive payment when due and to bring a suit to enforce that right. (See Section 508.)

Notice of Default

The trustee is required to give the registered holders of debt securities of the affected series notice of any default under the applicable indenture to the extent required by the Trust Indenture Act, unless the default has been cured or waived; except that in the case of an event of default of the character specified above in clause (d) under “—Events of Default,” no notice shall be given to such registered holders until at least 30 days after the occurrence of the default. The Trust Indenture Act currently permits the trustee to withhold notices of default (except for certain payment defaults) if the trustee in good faith determines the withholding of the notice to be in the interests of the registered holders. (See Section 602.)

We will furnish the trustee with an annual statement as to our compliance with the conditions and covenants in the applicable indenture.

Waiver of Default and of Compliance

The registered holders of a majority in aggregate principal amount of the outstanding debt securities of any series, voting as a single class, without regard to the holders of outstanding debt securities of any other series, may waive, on behalf of all registered holders of the debt securities of that series, any past default under the applicable indenture, except a default in the payment of principal, premium or interest, or with respect to compliance with certain provisions of the applicable indenture that cannot be amended without the consent of the registered holder of each outstanding debt security of that series. (See Section 513.)

Unless indicated differently in a prospectus supplement, compliance with certain covenants in the applicable indenture or otherwise provided with respect to debt securities of any series may be waived before the time specified for compliance by the registered holders of a majority in aggregate principal amount of the debt securities of such series. (See Section 1006.)

Consolidation, Merger and Conveyance of Assets as an Entirety; No Financial Covenants

Sempra Energy has agreed not to consolidate or merge with or into any other entity, or to sell, transfer, lease or otherwise convey its properties and assets as an entirety or substantially as an entirety to any entity, unless:

(a) (i) it is the continuing entity (in the case of a merger), or (ii) the successor entity formed by such consolidation or into which it is merged or which acquires by sale, transfer, lease or other conveyance its properties and assets, as an entirety or substantially as an entirety, is a corporation organized and existing under the laws of the United States of America or any State thereof or the District of Columbia, and expressly assumes, by supplemental indenture, the due and punctual payment of the principal, premium and interest on all the debt securities and the performance of all of the covenants under the indenture; and

(b) immediately after giving effect to the transaction, no event of default, and no event which after notice or lapse of time or both would become an event of default, has or will have occurred and be continuing.

15

Neither the applicable indenture nor the debt securities guarantee contains any financial or other similar restrictive covenants.

(See Section 801.)

Modification of Indenture

Without Registered Holder Consent. Without the consent of any registered holders of debt securities, Sempra Energy and the trustee may enter into one or more supplemental indentures for any of the following purposes:

(a) to evidence the succession of another entity to Sempra Energy; or

(b) to add one or more covenants for the benefit of the holders of all or any series of debt securities or to surrender any right or power conferred upon Sempra Energy; or

(c) to add any additional events of default for all or any series of debt securities; or

(d) to change or eliminate any provision of the applicable indenture so long as the change or elimination does not apply to any debt securities entitled to the benefit of such provision or to add any new provision to the applicable indenture (in addition to the provisions which may otherwise be added to the applicable indenture pursuant to the other clauses of this paragraph) so long as the addition does not apply to any outstanding debt securities; or

(e) to provide security for the debt securities of any series; or

(f) to establish the form or terms of debt securities of any series, as permitted by the applicable indenture; or

(g) to evidence and provide for the acceptance of appointment of a separate or successor trustee; or

(h) to cure any ambiguity, defect or inconsistency or to make any other changes with respect to any series of debt securities that does not adversely affect the interests of the holders of debt securities of that series in any material respect.

(See Section 901.)

With Registered Holder Consent. Subject to the following sentence, Sempra Energy and the trustee may, with some exceptions, amend or modify the applicable indenture with the consent of the registered holders of at least a majority in aggregate principal amount of the debt securities of each series affected by the amendment or modification. However, no amendment or modification may, without the consent of the registered holder of each outstanding debt security affected thereby:

(a) change the stated maturity of the principal or interest on any debt security or reduce the principal amount, interest or premium payable or change any place of payment where or the currency in which any debt security is payable, or impair the right to bring suit to enforce any payment;

(b) reduce the percentages of registered holders whose consent is required for any supplemental indenture or waiver; or

(c) modify certain provisions in the applicable indenture relating to supplemental indentures and waivers of certain covenants and past defaults.

A supplemental indenture which changes or eliminates any provision of the applicable indenture expressly included solely for the benefit of holders of debt securities of one or more particular series will be deemed not to affect the interests under the applicable indenture of the holders of debt securities of any other series.

(See Section 902.)

16

Defeasance

The indentures provide, unless the terms of the particular series of debt securities provide otherwise, that Sempra Energy may, upon satisfying several conditions, cause it to be discharged from its obligations, with some exceptions, with respect to any series of debt securities, which we refer to as “defeasance.”

One condition Sempra Energy must satisfy is the irrevocable deposit with the trustee, in trust, of money and/or government obligations which, through the scheduled payment of principal and interest on those obligations, would provide sufficient moneys to pay the principal of and any premium and interest on those debt securities on the maturity dates of the payments or upon redemption.

In addition, Sempra Energy will be required to deliver an opinion of counsel to the effect that a holder of debt securities will not recognize income, gain or loss for federal income tax purposes as a result of the defeasance and will be subject to federal income tax on the same amounts, at the same times and in the same manner as if that defeasance had not occurred. The opinion of counsel must be based upon a ruling of the Internal Revenue Service or a change in law after the date of the applicable indenture.

(See Article XIII.)

Satisfaction and Discharge

The applicable indenture will cease to be of further effect with respect to any series of debt securities, and we will be deemed to have satisfied and discharged all of our obligations under the applicable indenture, except as noted below, when:

• all outstanding debt securities of such series have become due or will become due within one year at their stated maturity or on a redemption date; and

• Sempra Energy deposits with the trustee, in trust, funds that are sufficient to pay and discharge all remaining indebtedness on the outstanding debt securities of such series.

Sempra Energy will remain obligated to pay all other amounts due under the applicable indenture and to perform certain ministerial tasks as described in the applicable indenture.

(See Section 401.)

Resignation and Removal of the Trustee; Deemed Resignation

The trustee with respect to any series of debt securities may resign at any time by giving written notice to us. The trustee may also be removed with respect to the debt securities of any series by act of the registered holders of a majority in principal amount of the then outstanding debt securities of such series. No resignation or removal of the trustee and no appointment of a successor trustee will become effective until the acceptance of appointment by a successor trustee in accordance with the requirements of the applicable indenture. Under certain circumstances, Sempra Energy may appoint a successor trustee with respect to such series of debt securities, and if the successor trustee accepts, the trustee will be deemed to have resigned. (See Section 610.)

Subordination

Unless indicated differently in a prospectus supplement, Sempra Energy’s subordinated debt securities will be subordinated in right of payment to the prior payment in full of all its senior debt. This means that upon:

(a) any distribution of the assets of Sempra Energy upon its dissolution, winding-up, liquidation or reorganization in bankruptcy, insolvency, receivership or other proceedings; or

(b) acceleration of the maturity of the subordinated debt securities; or

17

(c) a failure to pay any senior debt or interest thereon when due and continuance of that default beyond any applicable grace period; or

(d) acceleration of the maturity of any senior debt as a result of a default;

the holders of all of Sempra Energy’s senior debt will be entitled to receive:

• in the case of clauses (a) and (b) above, payment of all amounts due or to become due on all senior debt; and

• in the case of clauses (c) and (d) above, payment of all amounts due on all senior debt,

before the holders of any of the subordinated debt securities are entitled to receive any payment. So long as any of the events in clauses (a), (b), (c) or (d) above has occurred and is continuing, any amounts payable on the subordinated debt securities will instead be paid directly to the holders of all senior debt to the extent necessary to pay the senior debt in full and, if any payment is received by the subordinated indenture trustee under the subordinated indenture or the holders of any of the subordinated debt securities before all senior debt is paid in full, the payment or distribution must be paid over to the holders of the unpaid senior debt. Subject to paying the senior debt in full, the holders of the subordinated debt securities will be subrogated to the rights of the holders of the senior debt to the extent that payments are made to the holders of senior debt out of the distributive share of the subordinated debt securities. (See Section 1401.)

“senior debt” means with respect to the subordinated debt securities, the principal of, and premium, if any, and interest on and any other payment in respect of indebtedness due pursuant to any of the following, whether outstanding on the date the subordinated debt securities are issued or thereafter incurred, created or assumed:

(a) all of the indebtedness of Sempra Energy evidenced by notes, debentures, bonds or other securities sold by it for money or other obligations for money borrowed;

(b) all indebtedness of others of the kinds described in the preceding clause (a) assumed by or guaranteed in any manner by Sempra Energy or in effect guaranteed by Sempra Energy through an agreement to purchase, contingent or otherwise, as applicable; and

(c) all renewals, extensions or refundings of indebtedness of the kinds described in either of the preceding clauses (a) and (b), unless, in the case of any particular indebtedness, renewal, extension or refunding, the instrument creating or evidencing the same or the assumption or guarantee of the same by its terms provides that such indebtedness, renewal, extension or refunding is not superior in right of payment to or is pari passu with such securities. (See Section 101.)

Due to the subordination, if assets of Sempra Energy are distributed upon insolvency, certain of its general creditors may recover more, ratably, than holders of subordinated debt securities. The subordination provisions will not apply to money and securities held in trust under the satisfaction and discharge and the defeasance provisions of the applicable subordinated indenture. (See Section 1410.)

The subordinated debt securities and the subordinated indenture do not limit Sempra Energy or any of its subsidiaries’ ability to incur additional indebtedness, including indebtedness that will rank senior to subordinated debt securities. Sempra Energy expects that it will incur, and that its subsidiaries will incur, substantial additional amounts of indebtedness in the future. (See Section 301.)

Conversion Rights

The terms and conditions of any series of debt securities being offered that are convertible into common stock of Sempra Energy will be set forth in a prospectus supplement. These terms will include the conversion price, the conversion period, provisions as to whether conversion will be at the option of the holder or Sempra Energy, the events requiring an adjustment of the conversion price and provisions affecting conversion if such series of debt securities are redeemed.

18

Miscellaneous Provisions

Each indenture provides that certain debt securities, including those for which payment or redemption money has been deposited or set aside in trust as described under “—Satisfaction and Discharge” above, will not be deemed to be “outstanding” in determining whether the registered holders of the requisite principal amount of the outstanding debt securities have given or taken any demand, direction, consent or other action under the indenture as of any date, or are present at a meeting of registered holders for quorum purposes. (See Section 101.)

Sempra Energy will be entitled to set any day as a record date for the purpose of determining the registered holders of outstanding debt securities of any series entitled to give or take any demand, direction, consent or other action under the applicable indenture, in the manner and subject to the limitations provided in the applicable indenture. In certain circumstances, the trustee also will be entitled to set a record date for action by registered holders of any series of outstanding debt securities. If a record date is set for any action to be taken by registered holders of particular debt securities, the action may be taken only by persons who are registered holders of the respective debt securities on the record date. (See Section 104.)

Governing Law

Each indenture and the related debt securities will be governed by and construed in accordance with the laws of the State of New York. (See Section 112.)
