This registration statement registers the offer and sale of an
aggregate of 200,000,000 shares of the registrant's Common Stock as
described in the table, of which the registrant estimates that
170,000,000 shares are for use under the Duke Energy Retirement
Savings Plan, 20,000,000 shares are for use under the Duke Energy
Retirement Savings Plan for Legacy Cinergy Union Employees (Midwest),
and 10,000,000 shares are for use under the Duke Energy Retirement
Savings Plan for Legacy Cinergy Employees (IBEW 1393).
(2)
Estimated solely for the purpose of computing the amount of the
registration fee under Rules 457(c) and (h) of the Securities Act
based on the average of the high and low prices of the Common Stock
reported in the consolidated reporting system by the New York Stock
Exchange on July 30, 2010.
In
accordance with Rule 415(a)(6), this Registration Statement includes 10,365,328 shares of the
registrant's Common Stock previously registered for issuance under the registrant's Form S-8 filed
November 5, 2007, File No. 333-147132 (the "Prior Registration Statement"). Such shares were
unused for the plans described herein as of August 1, 2010. The
registrant paid a fee of $5,961
with respect to such shares upon the filing of the Prior Registration
Statement, and therefore a registration fee of $238,028 has been paid
with this filing, reflecting the reduction of the fee paid upon such
unused shares.
This Registration Statement shall become effective upon filing in accordance with Rule 462(a) under
the Securities Act.
