POWER OF ATTORNEY

      The undersigned, a person subject to ownership reporting pursuant to
Section 16(a) of the Securities Exchange Act of 1934, as amended (the "Exchange
Act"), and requirements pursuant to Rule 144 under the Securities Act of 1933,
as amended (the "Securities Act"), in respect of the equity securities of DCP
Midstream, LP, hereby makes, constitutes and appoints any of Julie P. Pradel,
Maine Goodfellow, Lisa D. Thompkins, and Debra M. Green my true and lawful
attorney-in-fact with full power and authority:
      (1)    to prepare, execute in my name and on my behalf, and file with the
U.S. Securities and Exchange Commission (the "SEC") any of the following forms
which I may be required or permitted to file:
             (A)    Form ID and any other documents necessary or appropriate to
         obtain codes and passwords enabling the undersigned to make electronic
         filings with the SEC of reports required by Section 16(a) of the
         Exchange Act or any rule or regulation of the SEC;
             (B)    Forms 3, 4 and 5 or any other reports or statements of
         beneficial ownership or changes of beneficial ownership necessary or
         appropriate under Section 16(a) of the Exchange Act; and
             (C)    Form 144, or any other notice of proposed sale of securities
         or other document necessary or appropriate under Rule 144 of the
         Securities Act.
     (2)    to do and perform any and all acts for and on my behalf which may be
necessary or desirable to complete and execute any such Form ID, 3, 4, 5, or
144, complete and execute any amendment or amendments thereto, and timely file
such form with the SEC and any stock exchange or similar authority.
      I hereby revoke any previous power of attorney I may have given to any
person to make and file such reports, statements and notices with respect to the
equity securities of DCP Midstream, LP.  This power of attorney shall remain in
force for so long as I may be subject to reporting obligations under Section
16(a) of the Exchange Act or the requirements of Rule 144 under the Securities
Act, unless earlier expressly revoked by me in writing and delivered to DCP
Midstream, LP.  Each of my attorneys-in-fact may at their sole discretion
designate one or more substitute attorneys-in-fact to act in their place.  I
acknowledge that my attorneys-in-fact, in serving in this capacity at my
request, are not assuming, nor is DCP Midstream, LP assuming, any of my
responsibilities to comply with the Exchange Act, the Securities Act, or the
rules and regulations thereunder.
