Duke Energy Corporation
Duke Energy, together with its subsidiaries, is a diversified energy company with both regulated and unregulated utility operations. We conduct
business through the following operating business segments: Electric Utilities and Infrastructure, Gas Utilities and Infrastructure, and Commercial
Renewables.
Duke Energy's Electric Utilities and Infrastructure segment conducts operations primarily through the regulated public utilities of Duke Energy
Carolinas, LLC, Duke Energy Progress, LLC, Duke Energy Florida, LLC, Duke Energy Indiana, LLC and Duke Energy Ohio, Inc. Duke Energy's
Electric Utilities and Infrastructure segment provides retail electric service through the generation, transmission, distribution and sale of electricity to
approximately 7.5 million customers within the Southeast and Midwest regions of the U.S. The service territory is approximately 95,000 square miles
across six states with a total estimated population of 24 million people. The operations include electricity sold wholesale to municipalities, electric
cooperative utilities and other load-serving entities. Duke Energy's Electric Utilities and Infrastructure segment is also a joint owner in certain electric
transmission projects.
Duke Energy's Gas Utilities and Infrastructure segment conducts natural gas operations primarily through the regulated public utilities of Piedmont
Natural Gas Company, Inc. ("Piedmont") and Duke Energy Ohio, Inc. Duke Energy's Gas Utilities and Infrastructure segment, which serves residential,
commercial, industrial and power generation natural gas customers, has over 1.5 million customers, including more than 1 million customers located in
North Carolina, South Carolina and Tennessee, and an additional 529,000 customers located within southwestern Ohio and northern Kentucky.
Duke Energy's Commercial Renewables segment primarily acquires, builds, develops and operates wind and solar renewable generation throughout
the continental U.S. The portfolio includes nonregulated renewable energy and energy storage businesses. This segment's renewable energy includes
utility-scale wind and solar generation assets which total 2,900 megawatts across 14 states from 21 wind farms and 63 commercial solar farms.
Revenues are primarily generated by selling the power produced from renewable generation through long-term contracts to utilities, electric
cooperatives, municipalities and commercial and industrial customers. In most instances, these customers have obligations under state-mandated
renewable energy portfolio standards or similar state or local renewable energy goals.
Duke Energy is a Delaware corporation. The address of Duke Energy's principal executive offices is 550 South Tryon Street, Charlotte, North
Carolina 28202-1803 and its telephone number is (704) 382-3853. Duke Energy's common stock is listed and trades on the New York Stock Exchange
under the symbol "DUK".
The foregoing information about Duke Energy is only a general summary and is not intended to be comprehensive. For additional information

supplement.

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 June 30, 2017, we had
approximately $14.9 billion of outstanding indebtedness, consisting of
approximately $14.4 billion of unsecured and unsubordinated indebtedness
and $0.5 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 June 30, 2017, our subsidiaries had
approximately $35.6 billion of indebtedness, payment upon approximately
$0.7 billion 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.

Use of Proceeds
The aggregate net proceeds from the sale of the Notes, after deducting the

repay at maturity $700 million aggregate principal amount of our 1.625%

paper and (iii) for general corporate purposes. At August 1, 2017, we had

has a weighted average interest rate of approximately 1.43% 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."
S-4
Table of Contents
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 1.625%
Senior Notes due August 15, 2017 described above or our commercial paper,
the repayment of which will be funded with a portion of the 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,

"Book-Entry System."

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' payment to us, will be approximately $1.7 billion. We intend to use the aggregate net proceeds from the sale of the
Notes (i) to repay at maturity $700 million aggregate principal amount of our 1.625% Senior Notes due August 15, 2017, (ii) to repay outstanding
commercial paper and (iii) for general corporate purposes. At August 1, 2017, we had approximately $3.1 billion of commercial paper outstanding. Our
outstanding commercial paper matures not later than 90 days after its date of issue and has a weighted average interest rate of approximately 1.43% 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 1.625% Senior Notes due August 15, 2017 described above or our commercial paper, the
repayment of which will be funded with a portion of the net proceeds from the sale of the Notes. See "Underwriting (Conflicts of Interest)--Conflicts of
Interest."
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.

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 three
separate 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 Seventeenth
Supplemental Indenture, to be dated as of August 10, 2017, 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 2022 Notes will be issued in an initial
aggregate principal amount of $500,000,000, the 2027 Notes will be issued in an initial aggregate principal amount of $750,000,000, and the 2047 Notes
will be issued in an initial aggregate principal amount of $500,000,000.
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 2022
Notes, the 2027 Notes or the 2047 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 such additional notes must be fungible with the applicable
Notes offered hereby for U.S. federal income tax purposes, and any such additional notes issued in this manner will be consolidated with, and will
form a single series with, the applicable previously issued 2022 Notes, 2027 Notes or 2047 Notes.
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 June 30, 2017, we had
approximately $14.9 billion of outstanding indebtedness, consisting of approximately $14.4 billion of unsecured and unsubordinated indebtedness and
$0.5 billion of unsecured junior subordinated indebtedness. Our Indenture 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 June 30, 2017, our subsidiaries had
approximately $35.6 billion of indebtedness, payment upon approximately $0.7 billion 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.
Interest and Payment
The 2022 Notes will mature on August 15, 2022 and will bear interest at a rate of 2.40% per year. The 2027 Notes will mature on August 15, 2027
and will bear interest at a rate of 3.15% per year. The
S-12
Table of Contents
2047 Notes will mature on August 15, 2047 and will bear interest at a rate of 3.95% per year. Interest on each series of the Notes shall be payable semi-
annually in arrears on February 15 and August 15 of each year, commencing on February 15, 2018. If an interest payment date falls on a day that is not a
business day, interest will be payable on the next succeeding business day (and without any interest or payment in respect of any such delay) with the
same force and effect as if made on such interest payment date. If a due date for the payment of interest or principal on the Notes falls on a day that is
not a business day, then the payment will be made on the next succeeding business day, and no interest will accrue on the amounts payable for the
period from and after the original due date and until the next business day. Interest will be paid to the person in whose name each Note is registered at
the close of business on the fifteenth calendar day next preceding each semi-annual interest payment date (whether or not a business day). Interest on
the Notes will be calculated on the basis of a 360-day year, consisting of twelve 30-day months. Interest on the Notes will accrue from August 10, 2017,
or from the most recent interest payment date to which interest has been paid or duly provided for.
Optional Redemption
We will have the right to redeem each series of the Notes at any time before the applicable Par Call Date (as set forth in the table below), 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 such Notes being redeemed and
(2) the sum of the present values of the remaining scheduled payments of principal and interest on such Notes being redeemed that would be due if such
Notes matured on the applicable Par Call Date (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 a number of basis points equal
to the applicable Make-Whole Spread (as set forth in the table below), plus, in each case, accrued and unpaid interest on the principal amount of such
Notes being redeemed to, but excluding, such redemption date.
We will have the right to redeem each series of the Notes at any time on or after the applicable Par Call Date, in whole or in part and from time to
time, at a redemption price equal to 100% of the principal amount of such series of Notes being redeemed plus accrued and unpaid interest on the
principal amount of such Notes being redeemed to, but excluding, such redemption date.
