Duke Energy Corporation is offering $600,000,000 aggregate principal amount of Senior Notes in two series. We are offering $300,000,000
aggregate principal amount of Floating Rate Senior Notes due 2022 (the "Floating Rate Notes") and $300,000,000 aggregate principal amount of
3.227% Senior Notes due 2022 (the "Fixed Rate Notes," and together with the Floating Rate Notes, the "Notes"). The per annum interest rate on
the Floating Rate Notes will be reset quarterly based on the three-month LIBOR plus 65 basis points. The per annum interest rate on the Fixed
Rate Notes will be 3.227%.

We will pay interest on the Floating Rate Notes quarterly in arrears on March 11, June 11, September 11 and December 11 of each year,
beginning on June 11, 2019. The Floating Rate Notes will mature as to principal on March 11, 2022. We will pay interest on the Fixed Rate Notes

principal on March 11, 2022.

We may redeem the Fixed Rate Notes at our option at any time, in whole or in part and from time to time, at the applicable redemption price,
as described in this prospectus supplement under the caption "Description of the Notes--Fixed Rate Notes--Optional Redemption." We may not
redeem the Floating Rate Notes prior to maturity. The Notes will not have the benefit of any sinking fund. The Notes will be our direct, unsecured
and unsubordinated obligations, ranking equally in priority with all of our existing and future unsecured and unsubordinated indebtedness and
senior in right of payment to all of our existing and future subordinated debt.

The Notes will not be listed on any securities exchange or included in any automated quotation system. Currently, there is no public market
for the Notes. Please read the information provided under the caption "Description of the Notes" in this prospectus supplement and "Description of

Notice to Prospective Investors in the European Economic Area

None of this prospectus supplement, the accompanying prospectus or any related free writing prospectus is a prospectus for the purposes
of the Prospectus Directive (as defined below). This prospectus supplement, the accompanying prospectus and any related free writing prospectus
have been prepared on the basis that any offer of the Notes in any Member State of the European Economic Area (the "EEA") which has
implemented the Prospectus Directive (each, a "Relevant Member State") will only be made to a legal entity which is a qualified investor under the
Prospectus Directive ("Qualified Investors"). Accordingly, any person making or intending to make an offer in that Relevant Member State of
Notes which are the subject of one of the offerings contemplated in this prospectus supplement, the accompanying prospectus and any related free
writing prospectus may only do so with respect to Qualified Investors. Neither Duke Energy Corporation nor the underwriters have authorized, nor
do they authorize, the making of any offer of Notes other than to Qualified Investors. The expression "Prospectus Directive" means Directive
2003/71/EC (as amended or superseded), and includes any relevant implementing measure in the Relevant Member State.

Prohibition of Sales to EEA Retail Investors--The Notes are not intended to be offered, sold or otherwise made available to and should
not be offered, sold or otherwise made available to any retail investor in the EEA. For these purposes, a retail investor means a person who is one
(or more) of: (i) a retail client as defined in point (11) of Article 4(1) of Directive 2014/65/EU, as amended ("MiFID II"); or (ii) a customer within
the meaning of Directive (EU) 2016/97, as amended or superseded (the "Insurance Distribution Directive"), where that customer would not qualify
as a professional client as defined in point (10) of Article 4(1) of MiFID II; or (iii) not a qualified investor as defined in the Prospectus Directive.
Consequently no key information document required by Regulation (EU) No 1286/2014, as amended (the "PRIIPs Regulation") for offering or
selling the Notes or otherwise making them available to retail investors in the EEA has been prepared and therefore offering or selling the Notes or

We are offering $300,000,000 aggregate principal amount of the Floating Rate Notes and
$300,000,000 aggregate principal amount of the Fixed Rate Notes.

Maturity Dates
The Floating Rate Notes will mature on March 11, 2022. The Fixed Rate Notes will mature on
March 11, 2022.

Interest Rates
The per annum interest rate on the Floating Rate Notes will be reset quarterly based on the three-
month LIBOR plus 65 basis points.

The per annum interest rate on the Fixed Rate Notes will be 3.227%.

Interest Payment Dates
Interest on the Floating Rate Notes will be payable quarterly in arrears on March 11, June 11,
September 11 and December 11 of each year, beginning on June 11, 2019.

Interest on the Fixed Rate Notes will be payable semi-annually in arrears on March 11 and
September 11 of each year, beginning on September 11, 2019.

Ranking
The Notes will be two new series of our direct, unsecured and unsubordinated obligations, ranking
equally in priority with all of our existing and future unsecured and unsubordinated indebtedness
and senior in right of payment to all of our existing and future subordinated debt. At December 31,
2018, we had approximately $16.5 billion of outstanding indebtedness, consisting of approximately
$15.5 billion of unsecured and unsubordinated indebtedness and $1.0 billion of unsecured junior
subordinated indebtedness. Our Indenture (as defined herein) contains no restrictions on the amount
of additional indebtedness that we may issue under it.

The Notes will be structurally subordinated to all liabilities and any preferred stock of our
subsidiaries. At December 31, 2018, our subsidiaries had approximately $39.2 billion of
indebtedness, payment upon approximately $650 million of which is guaranteed by Duke Energy
Corporation. All of such guarantees were granted to the holders of certain unsecured debt of our
subsidiary Duke Energy Carolinas, LLC, in connection with changes in our corporate structure
relating to the closing of our merger with Cinergy Corp. in 2006.

Optional Redemption
We will have the right to redeem the Fixed Rate Notes at any time, in whole or in part and from
time to time, at a redemption price equal to the greater of (1) 100% of the principal amount of the

payments of principal and interest on the Fixed Rate Notes being redeemed (exclusive of interest
accrued to the redemption date), discounted to the redemption date on a semi-annual basis
(assuming a 360-day year

consisting of twelve 30-day months) at the Treasury Rate (as defined herein) plus 15 basis points,
plus, in either case, accrued and unpaid interest on the principal amount of the Fixed Rate Notes
being redeemed to, but excluding, such redemption date.

We may not redeem the Floating Rate Notes prior to their maturity.

No Sinking Fund
There will not be any sinking fund for the Notes.

Use of Proceeds
The aggregate net proceeds from the sale of the Notes, after deducting the respective underwriting
discounts and related offering expenses and giving effect to the underwriters' reimbursement to us,
will be approximately $597.8 million. The aggregate net proceeds from the sale of the Notes are
expected to be used to repay a portion of our outstanding commercial paper and for general
corporate purposes. At February 28, 2019, we had approximately $3.0 billion of commercial paper
outstanding. Our outstanding commercial paper has a weighted average interest rate of
approximately 2.77% per year. We issue commercial paper from time to time to fund our working
capital and other needs and those of our subsidiaries. See "Use of Proceeds."

We expect that the sale of each series of the Notes will take place concurrently. However, the sales
of the Notes are not conditioned upon each other, and we may consummate the sale of one or more
series of Notes and not any of the other series of Notes, or consummate the sales at different times.

Conflicts of Interest
Certain of the underwriters or their affiliates may own some of our commercial paper, the
repayment of which will be funded with the aggregate net proceeds from the sale of the Notes. See
"Underwriting (Conflicts of Interest)--Conflicts of Interest."

Book-Entry
Each series of the Notes will be represented by one or more global securities registered in the name
of and deposited with or on behalf of The Depository Trust Company ("DTC") or its nominee.
Beneficial interests in each series of the Notes will be represented through book-entry accounts of
financial institutions acting on behalf of beneficial owners as direct and indirect participants in
DTC. Investors may elect to hold interests in the global securities through either DTC in the United
States or Clearstream Banking, S.A. ("Clearstream") or Euroclear Bank S.A./N.V., as operator of
the Euroclear System (the "Euroclear System"), in Europe if they are participants in those systems,
or indirectly through organizations which are participants in those systems. This means that you
will not receive a certificate for your Notes and Notes will not be registered in your name, except
under certain limited circumstances described under the caption "Book-Entry System."

Risk Factors
An investment in the Floating Rate Notes involves risks. You should carefully consider the
discussion of risks in "Risk Factors" in this prospectus supplement and the other information in this
prospectus supplement and the accompanying prospectus, including "Cautionary Statement
Regarding Forward-Looking Information" in this prospectus supplement, before making an
investment decision.

Table of Contents

RISK FACTORS

In addition to the risk factors described below, you should carefully consider the risk factors in our Annual Report on Form 10-K for the year
ended December 31, 2018, which has been filed with the Securities and Exchange Commission (the "SEC") and is incorporated by reference in
this prospectus supplement and the accompanying prospectus, as well as all of the other information included or incorporated by reference in this
prospectus supplement and the accompanying prospectus, before making an investment decision.

Additional Risks Related to the Floating Rate Notes
https://www.sec.gov/Archives/edgar/data/1326160/000110465919013328/a19-5892_1424b5.htm[3/7/2019 2:13:57 PM]

Uncertainty relating to the LIBOR calculation process and potential phasing out of LIBOR after 2021 may adversely affect the value of the
Floating Rate Notes.

Regulators and law enforcement agencies in the United Kingdom and elsewhere are conducting civil and criminal investigations into whether
the banks that contribute to the British Bankers' Association (the "BBA") in connection with the calculation of daily LIBOR may have been under-
reporting or otherwise manipulating or attempting to manipulate LIBOR. A number of BBA member banks have entered into settlements with their
regulators and law enforcement agencies with respect to this alleged manipulation of LIBOR.

Actions by the BBA, regulators or law enforcement agencies may result in changes to the manner in which LIBOR is determined or the
establishment of alternative reference rates. For example, on July 27, 2017, the United Kingdom's Financial Conduct Authority announced that it
intends to stop persuading or compelling banks to submit LIBOR rates after 2021. At this time, it is not possible to predict the effect that these
developments, any discontinuance, modification or other reforms to LIBOR or any other reference rate, or the establishment of alternative reference
rates may have on LIBOR, other benchmarks or floating rate debt securities, including the Floating Rate Notes. Uncertainty as to the nature of such
potential discontinuance, modification, alternative reference rates or other reforms may materially adversely affect the trading market for securities
linked to such benchmarks, including the Floating Rate Notes. Furthermore, the use of alternative reference rates or other reforms could cause the
interest rate calculated for the Floating Rate Notes, and consequently the value of the Floating Rate Notes, to be materially lower than expected.

If the Calculation Agent is unable to determine three-month LIBOR based on screen-based reporting or if three-month LIBOR is
discontinued, interest on the Floating Rate Notes will be calculated by alternative means, which could adversely affect the interest rate on the
Floating Rate Notes and the return on, value of and market for the Floating Rate Notes.

Under the terms of the Floating Rate Notes, the interest rate on the Floating Rate Notes is based on three-month LIBOR. If the Calculation
Agent is unable to determine three-month LIBOR based on screen-based reporting of that base rate, except where LIBOR has been discontinued,
LIBOR will be determined on the basis of (i) the rates at which deposits in U.S. dollars for the Interest Period (as defined herein) and in a principal
amount of not less than $1,000,000 are offered to prime banks in the London interbank market or, under certain circumstances, (ii) the rates quoted
by three major banks in New York City for loans in U.S. dollars to leading European banks for that Interest Period and in a principal amount of not
less than $1,000,000. If the Calculation Agent is also unable to obtain suitable quotations, LIBOR for that Interest Period will be the same as
LIBOR as determined for the previous Interest Period.

In addition, if we determine on the relevant Interest Determination Date (as defined herein) that LIBOR for deposits in U.S. dollars having an
index maturity of three months in amounts of at least $1,000,000 has been permanently discontinued, or the reference to LIBOR becomes illegal, or
most other debt obligations similar to the Floating Rate Notes have converted away from LIBOR to a new reference rate, the Calculation Agent
will use, as directed by us, as a substitute for three-month LIBOR, the alternative reference rate selected by the central bank, reserve bank,
monetary authority or similar institution (including any committee or working group thereof) that is consistent with accepted market practice. In
such instances, the Calculation Agent will, as directed by us, make such adjustments to the Alternative Rate (as defined herein) and the spread
thereon to

S-6
Table of Contents

account for the basis between LIBOR and the Alternative Rate, as well as the business day convention, Interest Determination Dates (as defined
herein) and related provisions and definitions, in each case that are consistent with accepted market practice for the use of such Alternative Rate for
floating rate debt securities such as the Floating Rate Notes. If we determine that the three-month LIBOR has been permanently discontinued and
no Alternative Rate has been determined, we may appoint in our sole discretion an independent financial advisor (the "IFA") to determine an
appropriate Alternative Rate, and any Adjustments, and the decision of the IFA will be binding on us, the Calculation Agent, the Trustee and the
holders of the Floating Rate Notes. If, however, we determine that LIBOR has been discontinued, but for any reason an Alternative Rate has not
been determined, LIBOR will be equal to such rate on the Interest Determination Date when LIBOR for deposits in U.S. dollars having an index
maturity of three months in amounts of at least $1,000,000 was last available on BBAM (as defined herein) and, if such page is not available from
the Reuters LIBOR01 Page, as determined by the Calculation Agent. See "Description of the Notes--Interest and Payment--Floating Rate
Notes." Any of the foregoing determinations or actions could result in adverse consequences to the interest rate on the Floating Rate Notes, which
could adversely affect the return on, value of and market for the Floating Rate Notes.

Regulation and reform of interest rate "benchmarks," including LIBOR, may cause such "benchmarks" to perform differently than in the
past, to disappear entirely or to have other consequences which cannot be predicted.

LIBOR and other interest rate, foreign exchange rate and other types of indices which are deemed to be "benchmarks" are the subject of recent
international, national and other regulatory guidance and proposals for reform. Some of these reforms are already effective while others are still to
be implemented. These reforms may cause such "benchmarks" to perform differently than in the past, or to disappear entirely, or have other
https://www.sec.gov/Archives/edgar/data/1326160/000110465919013328/a19-5892_1424b5.htm[3/7/2019 2:13:57 PM]

consequences which cannot be predicted. Any such consequence could have a material adverse effect on the return on, value of and market for the
Floating Rate Notes. Any of the international, national or other proposals for reform or the general increased regulatory scrutiny of LIBOR and
other "benchmarks" could increase the costs and risks of administering or otherwise participating in the setting of such "benchmarks" and
complying with any such regulations or requirements. Such factors may have the effect of discouraging market participants from continuing to
administer or contribute to certain "benchmarks," trigger changes in the rules or methodologies used in certain "benchmarks" or lead to the
disappearance of certain "benchmarks." In particular, changes in the manner of administration of LIBOR could result in adverse consequences to
the interest rate on the Floating Rate Notes, which could adversely affect the return on, value of and market for the Floating Rate Notes.

USE OF PROCEEDS

The aggregate net proceeds from the sale of the Notes, after deducting the respective underwriting discounts and related offering expenses and
giving effect to the underwriters' reimbursement to us, will be approximately $597.8 million. The aggregate net proceeds from the sale of the
Notes are expected to be used to repay a portion of our outstanding commercial paper and for general corporate purposes. At February 28, 2019,
we had approximately $3.0 billion of commercial paper outstanding. Our outstanding commercial paper has a weighted average interest rate of
approximately 2.77% per year. We issue commercial paper from time to time to fund our working capital and other needs and those of our
subsidiaries. Certain of the underwriters or their affiliates may own some of our commercial paper, the repayment of which will be funded with the
aggregate net proceeds from the sale of the Notes. See "Underwriting (Conflicts of Interest)--Conflicts of Interest."

We expect that the sales of the Floating Rate Notes and the Fixed Rate Notes will take place concurrently. However, the sales of the Floating
Rate Notes and the Fixed Rate Notes are not conditioned upon each other, and we may consummate the sale of one series and not the other, or
consummate the sales at different times.

DESCRIPTION OF THE NOTES

General

The following description of the terms of the Notes summarizes certain general terms that will apply to the Notes. The Notes will be issued as
two new series of senior debt securities under an Indenture between us and The Bank of New York Mellon Trust Company, N.A. (formerly known
as The Bank of New York Trust Company, N.A.), as Trustee, dated as of June 3, 2008, as supplemented from time to time, including by the
Twenty-first Supplemental Indenture, to be dated as of March 11, 2019, collectively referred to as the "Indenture."

Please read the following information concerning the Notes in conjunction with the statements under "Description of Debt Securities" in the
accompanying prospectus, which the following information supplements and, in the event of any inconsistencies, supersedes. Capitalized terms not
defined in this prospectus supplement are used as defined in the Indenture or as otherwise provided in the accompanying prospectus.

The Notes are issuable in denominations of $2,000 or any integral multiple of $1,000 in excess thereof.

The Floating Rate Notes will be issued in an initial aggregate principal amount of $300,000,000 and the Fixed Rate Notes will be issued in an
initial aggregate principal amount of $300,000,000.

We may from time to time, without the consent of existing holders, create and issue further notes having the same terms and conditions as the
Floating Rate Notes or Fixed Rate Notes being offered hereby in all respects, except for the issue date, the issue price and, if applicable, the first
payment of interest thereon and the initial interest accrual date; provided, however, that any such additional notes must be fungible with the then
outstanding Floating Rate Notes or Fixed Rate Notes, as the case may be, for U.S. federal income tax purposes, and any such additional notes,
together with the then outstanding notes of such series, will be taken to constitute the same series of notes under the Indenture.

As used in this prospectus supplement, "business day" means, with respect to the Notes, any day other than a Saturday or Sunday that is
neither a legal holiday in New York, New York nor a day on which banking institutions in New York, New York are authorized or required by law,
regulation or executive order to close, or a day on which the Corporate Trust Office is closed for business.

Ranking

The Notes will be our direct, unsecured and unsubordinated obligations, ranking equally in priority with all of our existing and future
unsecured and unsubordinated indebtedness and senior in right of payment to all of our existing and future subordinated debt. At December 31,
2018, we had approximately $16.5 billion of outstanding indebtedness, consisting of approximately $15.5 billion of unsecured and unsubordinated
indebtedness and $1.0 billion of unsecured junior subordinated indebtedness. Our Indenture contains no restrictions on the amount of additional
