                                -----------------


         The undersigned, Peter Stokes (the "Undersigned"), does hereby
nominate, constitute and appoint Heidi Mortensen (an "Attorney-in-Fact") as the
Undersigned's true and lawful agent and attorney-in-fact, with full power and
authority of substitution and revocation and to act singly hereunder, in the
discretion of such Attorney-in-Fact, in the name of and on behalf of the
Undersigned as fully as the Undersigned could if the Undersigned were present
and acting in person, to perform any and all acts that may be necessary or
desirable to complete, make and execute any and all required or voluntary
filings (the "Filings") under Section 16(a) of the Securities Exchange Act of
1934, as amended (the "Exchange Act"), and the applicable rules and regulations
thereunder, with the Securities and Exchange Commission, the New York Stock
Exchange, Macquarie Infrastructure Company LLC (the "Company"), and any other
person or entity to which such filings may be required under Section 16(a) of
the Exchange Act as a result of the Undersigned's position as an officer and/or
director of the Company or the Undersigned's "Beneficial Ownership" (within the
meaning of Section 16(a) of the Exchange Act) of more than ten percent of any
class of equity securities of the Company.

         The Undersigned hereby consents to, ratifies and confirms all that the
said Attorney-in-Fact shall do or cause to be done by virtue of this Power of
Attorney. The Undersigned hereby acknowledges that the Attorney-in-Fact, in
serving in such capacity at the request of the Undersigned, is not assuming, nor
is the Company assuming, any of the Undersigned's responsibilities to comply
with Section 16 of the Exchange Act.

         This Power of Attorney shall remain in full force and effect from this
date forward for the term of the Undersigned's service as an officer and/or
director of the Company or the Undersigned's Beneficial Ownership of more than
ten percent of any class of equity securities of the Company and for such time
thereafter as may be necessary to make any such Filings, unless earlier revoked
or modified by the Undersigned in writing. The Undersigned hereby revokes all
prior powers of attorney relating to the foregoing acts.

         IN WITNESS WHEREOF, the Undersigned has hereunto signed this Power of
Attorney this 15th day of December, 2004.
