Report of Independent Registered Public Accounting Firm

To the Board of Trustees and Shareholders of Franklin Custodian Funds
In planning and performing our audit of the financial statements of
Franklin US Government Securities Fund, Franklin Growth Fund,
Franklin Utilities Fund, Franklin Dynatech Fund, Franklin
Income Fund, and Franklin Focused Growth Fund
(collectively the "Funds") as of and for the year ended
September 30, 2018, in accordance with the standards of
the Public Company Accounting Oversight Board (United States)
 ("PCAOB"), we considered the Funds' internal control over
financial reporting, including controls over safeguarding
securities, as a basis for designing our auditing procedures
 for the purpose of expressing our opinion on the financial
statements and to comply with the requirements of Form N-CEN,
 but not for the purpose of expressing an opinion on the
effectiveness of the Funds' internal control over financial
 reporting.  Accordingly, we do not express an opinion on
the effectiveness of the Funds' internal control over
 financial reporting.
The management of the Funds is responsible for establishing
 and maintaining effective internal control over financial reporting.
  In fulfilling this responsibility, estimates and judgments by
 management are required to assess the expected benefits and related
costs of controls.  A company's internal control over financial
 reporting is a process designed to provide reasonable assurance
regarding the reliability of financial reporting and the preparation
 of financial statements for external purposes in accordance with
 generally accepted accounting principles.  A company's internal
control over financial reporting includes those policies and
procedures that (1) pertain to the maintenance of records that,
 in reasonable detail, accurately and fairly reflect the transactions
 and dispositions of the assets of the company; (2) provide
reasonable assurance that transactions are recorded as necessary
 to permit preparation of financial statements in accordance with
 generally accepted accounting principles, and that receipts and
 expenditures of the company are being made only in accordance with
 authorizations of management and directors of the company; and
(3) provide reasonable assurance regarding prevention or timely
 detection of unauthorized acquisition, use or disposition of
a company's assets that could have a material effect on the
 financial statements.
Because of its inherent limitations, internal control over
 financial reporting may not prevent or detect misstatements.
  Also, projections of any evaluation of effectiveness to future
 periods are subject to the risk that controls may become inadequate
 because of changes in conditions, or that the degree of compliance
 with the policies or procedures may deteriorate.
A deficiency in internal control over financial reporting exists
when the design or operation of a control does not allow management
 or employees, in the normal course of performing their assigned
 functions, to prevent or detect misstatements on a timely basis.
  A material weakness is a deficiency, or a combination of
deficiencies, in internal control over financial reporting,
 such that there is a reasonable possibility that a material
 misstatement of the company's annual or interim financial
statements will not be prevented or detected on a timely basis.
Our consideration of the Funds' internal control over financial
 reporting was for the limited purpose described in the first
 paragraph and would not necessarily disclose all deficiencies
 in internal control over financial reporting that might be
material weaknesses under standards established by the PCAOB.
  However, we noted no deficiencies in the Funds' internal
 control over financial reporting and its operation, including
 controls over safeguarding securities, that we consider to be
 a material weakness as defined above as of September 30, 2018.
This report is intended solely for the information and use of
 the Board of Trustees of Franklin Custodian Funds and the
Securities and Exchange Commission and is not intended to be
 and should not be used by anyone other than these specified parties.
