Notice to Prospective Investors in the European Economic Area
Neither this prospectus supplement nor the accompanying prospectus is a prospectus for the purposes of the Prospectus Directive (as defined
below). This prospectus supplement and the accompanying prospectus have been prepared on the basis that any offer of the Mortgage Bonds 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 Mortgage Bonds which are the subject of the offering contemplated in this prospectus
supplement and the accompanying prospectus may only do so with respect to Qualified Investors. Neither Duke Energy Florida nor the underwriters
have authorized, nor do they authorize, the making of any offer of Mortgage Bonds other than to Qualified

relevant implementing measure in the Relevant Member State.
PRIIPs Regulation / Prospectus Directive / Prohibition of sales to EEA retail investors --The Mortgage Bonds 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 2002/92/EC, as amended (the "Insurance Mediation 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 Mortgage Bonds or otherwise making them available to retail investors in the EEA has been prepared and therefore offering or selling the
Mortgage Bonds or otherwise making them available to any retail investor in the EEA may be unlawful under the PRIIPs Regulation.

See "Description of the Mortgage Bonds--Redemption--Special Redemption."

No Sinking Fund
The Mortgage Bonds will not be entitled to the benefit of any sinking fund or
to a special redemption by operation of a sinking fund.

Basis for Issuance of Additional First
We will issue the Mortgage Bonds based upon the amount of previously
Mortgage Bonds
authenticated First Mortgage Bonds that have been cancelled or delivered for
cancellation. Under the terms of the Mortgage, (i) as of March 31, 2018, we
could issue additional First Mortgage Bonds in amounts up to approximately
$2.9 billion based upon the bondable value of property additions and (ii) as of
June 15, 2018, we could issue additional First Mortgage Bonds in amounts
equal to approximately $1.3 billion (approximately $300 million after giving
effect to the offerings) based upon the amount of previously authenticated First
Mortgage Bonds that have been cancelled or delivered for cancellation.

Use of Proceeds
The aggregate net proceeds from the sale of the Mortgage Bonds, after
deducting the respective underwriting discounts and related offering expenses
and giving effect to the underwriters' payment to us, will be approximately
$991.7 million. The aggregate net proceeds from the sale of the Mortgage
Bonds will be used (i) to repay a portion of our outstanding intercompany
short-term debt under our money-pool borrowing arrangement with Duke
Energy Corporation and a portion of our outstanding commercial paper, which
borrowings were used to repay at maturity the 5.65% Bonds and (ii) for general
company purposes, including to fund capital expenditures for ongoing
construction and capital maintenance. At June 15, 2018, we had approximately
$389 million of outstanding money-pool and commercial paper borrowings at
an annual interest rate of 2.28%.
S-4
Table of Contents
We expect that the sales of the 2028 Mortgage Bonds and the 2048 Mortgage
Bonds will take place concurrently. However, the sales of the 2028 Mortgage
Bonds and the 2048 Mortgage Bonds 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.

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

Book-Entry
Each series of the Mortgage Bonds 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 Mortgage Bonds 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 Mortgage Bonds and Mortgage Bonds will not be
registered in your name, except under certain limited circumstances described
under the caption "Book-Entry System."

CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING INFORMATION
This prospectus supplement, the accompanying prospectus, and the information incorporated by reference herein and therein, include forward-
looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended and Section 21E of the Securities Exchange Act of

"forecast," "target," "guidance," "outlook," or other similar terminology. Various factors may cause actual results to be materially different than the
suggested outcomes within forward-looking statements; accordingly, there is no assurance that such results will be realized. These factors include, but
are not limited to:
·
State and federal legislative and regulatory initiatives, including costs of compliance with existing and future environmental
requirements, including those related to climate change, as well as rulings that affect cost and investment recovery or have an impact on
rate structures or market prices;
·
The extent and timing of costs and liabilities to comply with federal and state laws, regulations, and legal requirements related to coal
ash remediation, including amounts for required closure of certain ash impoundments, are uncertain and difficult to estimate;
·
The ability to recover eligible costs, including amounts associated with coal ash impoundment retirement obligations and costs related to
significant weather events, and to earn an adequate return on investment through rate case proceedings and the regulatory process;
·
The costs of decommissioning Crystal River Unit 3 and other nuclear facilities could prove to be more extensive than amounts estimated
and all costs may not be fully recoverable through the regulatory process;
·
Costs and effects of legal and administrative proceedings, settlements, investigations and claims;
·
Industrial, commercial and residential growth or decline in our service territories or customer bases resulting from sustained downturns
of the economy and the economic health of our service territories or variations in customer usage patterns, including energy efficiency
efforts and use of alternative energy sources, such as self-generation and distributed generation technologies;
·
Federal and state regulations, laws and other efforts designed to promote and expand the use of energy efficiency measures and
distributed generation technologies, such as private solar and battery storage, in Duke Energy Florida service territories could result in
customers leaving the electric distribution system, excess generation resources as well as stranded costs;
·
Advancements in technology;
·
Additional competition in electric and natural gas markets and continued industry consolidation;
·
The influence of weather and other natural phenomena on our operations, including the economic, operational and other effects of severe
storms, hurricanes, droughts, earthquakes and tornadoes, including extreme weather associated with climate change;

USE OF PROCEEDS
The aggregate net proceeds from the sale of the Mortgage Bonds, after deducting the respective underwriting discounts and related offering
expenses and giving effect to the underwriters' payment to us, will be approximately $991.7 million. The aggregate net proceeds from the sale of the
Mortgage Bonds will be used (i) to repay a portion of our outstanding intercompany short-term debt under our money-pool borrowing arrangement
with Duke Energy Corporation and a portion of our outstanding commercial paper, which borrowings were used to repay at maturity the 5.65% Bonds
and (ii) for general company purposes, including to fund capital expenditures for ongoing construction and capital maintenance. At June 15, 2018, we
had approximately $389 million of outstanding money-pool and commercial paper borrowings at an annual interest rate of 2.28%. Some of the
underwriters or their affiliates may own some of our commercial paper, the repayment of which will be funded with a portion of the aggregate net
proceeds from the sale of the Mortgage Bonds. See "Underwriting (Conflicts of Interest)--Conflicts of Interest."
We expect that the sales of the 2028 Mortgage Bonds and the 2048 Mortgage Bonds will take place concurrently. However, the sales of the 2028
Mortgage Bonds and the 2048 Mortgage Bonds 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 MORTGAGE BONDS
We will issue the Mortgage Bonds as two new series of First Mortgage Bonds under an Indenture, dated as of January 1, 1944 (the "Original
Indenture"), with The Bank of New York Mellon, as successor trustee (the "Mortgage Trustee"). The Original Indenture is supplemented by
supplemental indentures, including by the Fifty-Fifth Supplemental Indenture to be dated as of June 1, 2018 (the "Supplemental Indenture"), which
establishes the specific terms of the Mortgage Bonds. In the following discussion, we will refer to the Original Indenture and all indentures
supplemental to the Indenture together as the "Mortgage."
Please read the following information concerning the Mortgage Bonds in conjunction with the statements under "Description of First Mortgage
Bonds" 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 Mortgage and the Supplemental Indenture governing the Mortgage Bonds or
as otherwise provided in the accompanying prospectus.
General
We will initially offer $1,000,000,000 aggregate principal amount of the Mortgage Bonds, consisting of $600,000,000 aggregate principal amount
of the 2028 Mortgage Bonds and $400,000,000 aggregate principal amount of the 2048 Mortgage Bonds. Subject to the limits contained in the Mortgage
that are described under "--Basis for Issuance of the Mortgage Bonds," we may, at any time, without the consent of the holders of the Mortgage Bonds,
issue additional First Mortgage Bonds having the same ranking, interest rate, maturity and other terms as the Mortgage Bonds of either series being
offered hereby; provided, however, that such additional First Mortgage Bonds must be fungible with the applicable Mortgage Bonds offered hereby for
U.S. federal income tax purposes, and any such additional First Mortgage Bonds, together with the Mortgage Bonds of such series, will be taken to
constitute the same series of First Mortgage Bonds under the Mortgage.
The Mortgage Bonds will be issuable in denominations of $2,000 and integral multiples of $1,000 above that amount. For more information on
DTC, see "Book-Entry System--The Depository Trust Company" below.
Basis for Issuance of the Mortgage Bonds
We will issue the Mortgage Bonds under the Mortgage based upon the amount of previously authenticated First Mortgage Bonds that have been
cancelled or delivered for cancellation.
