Exhibit 10.7

WORKING CAPITAL LOAN AGREEMENT

This Working Capital Loan Agreement (this “Agreement”) is made as of ___, 2007 (the
“Effective Date”), between The Williams Companies, Inc., a Delaware corporation, with principal
offices at One Williams Center, Tulsa, Oklahoma 74172 (“Lender”) and Williams Pipeline Partners
L.P., a Delaware limited partnership with principal offices at One Williams Center, Tulsa, Oklahoma
74172 (“Borrower”).

1. Loan. Lender shall make revolving loans to Borrower during the term of this Agreement in an
aggregate amount outstanding of up to, but not exceeding, $20,000,000.00 at any time (the “Loan”).

2. Term. Borrower may borrow sums (each, a “Borrowing”) from Lender up to the total amount of the
Loan at any time from the Effective Date through the 365th day following the Effective Date (the
“Maturity Date”). Borrower may extend the term of the Loan for another 365-day term upon notice to
Lender given at least five business days prior to the Maturity Date. If the term is so extended,
“Maturity Date” shall mean the last day of the term as extended. Notwithstanding the foregoing,
for a period of at least fifteen consecutive days during each 365-day period commencing with the
period commencing on the Effective Date, Borrower shall have no Borrowings under the Loan
outstanding. Borrower promises to pay to Lender interest when due hereunder and all outstanding
principal, interest and other payments owing under this Agreement in full on the Maturity Date.

3. Early Termination. Notwithstanding anything contained in this Agreement to the contrary, in the
event of a Change of Control (hereinafter defined) of the General Partner (hereinafter defined),
the Maturity Date shall be deemed to have immediately occurred as of the date of such Change of
Control. As used herein, the following terms shall have the following meanings: “General Partner”
means Williams Pipeline Partners GP LLC, a Delaware limited liability company (including any
permitted successors and assigns under the Agreement of Limited Partnership of Borrower dated
August 31, 2007 by and between the General Partner and Williams Pipeline Services Company, as
amended from time to time). “Change of Control” means any of the following events: (i) any sale,
lease, exchange or other transfer (in one transaction or a series of related transactions) of all
or substantially all of the General Partner’s assets to any other Person, unless immediately
following such sale, lease, exchange or other transfer such assets are owned, directly or
indirectly, by Lender; (ii) the dissolution or liquidation of the General Partner; (iii) the
consolidation or merger of the General Partner with or into another Person pursuant to a
transaction in which the outstanding membership interests of the General Partner are changed into
or exchanged for cash, securities or other property, other than any such transaction where (a)
outstanding membership interests of the General Partner are changed into or exchanged for Voting
Securities of the surviving Person or its parent and (b) Lender continues to own, directly or
indirectly, not less than a majority of the outstanding Voting Securities of the surviving Person
or its parent immediately after such transaction; and (iv) other than Lender and its affiliates, a
“person” or “group” (within the meaning of Sections 13(d) or 14(d)(2) of the Exchange Act) being or
becoming the “beneficial owner” (as defined in Rules 13d-3 and 13d-5 under the Exchange Act) of
more than 50% of all of the then outstanding membership interests of the General Partner, except in
a merger or consolidation that would not constitute a Change of Control under clause (iii) above.
“Exchange Act” means the Securities

Page 1

 

Exchange Act of 1934, as amended. “Person” means a corporation, partnership, joint venture, trust,
limited liability company, unincorporated organization or any other entity. “Voting Securities”
means securities of any class of Person entitling the holders thereof to vote in the election of
members of the board of directors or other similar governing body of the Person, or in the case of
a limited partnership, a majority of the general partner interests in such limited partnership.

4. Procedure for Borrowing. Borrower may initiate Borrowings in amounts of not less than
$50,000.00, and in additional multiples of not less than $5,000.00, by giving written notice to
Lender. Each Borrowing shall be requested on a business day with a same day notice by 10:00 a.m.
(Tulsa, Oklahoma time) the day of the proposed Borrowing. Any notice received after 10:00 a.m.
(Tulsa, Oklahoma time) shall be deemed to be received the next business day.

5. Revolving Nature and Availability. Subject to the terms and conditions hereof, Borrower may
increase or decrease Borrowings made under this Agreement by making drawdowns, repayments and
further drawdowns.

6. Conditions of Loan and Borrowing. The obligation of Lender to make the Loan and any Borrowing
is subject to the following conditions:

     (a) No event shall have occurred that would constitute a Default (as defined below) or that
with the giving of notice or lapse of time, or both, would become a Default and was not waived by
Lender; and

     (b) The proceeds of the proposed Borrowing shall be used by Borrower for working capital
purposes, as reasonably determined by Borrower, including the payment of distributions to the
limited partners of Borrower.

7. Interest. Borrower promises to pay interest on the unpaid principal amount of the Loan on the
last day of each quarter or each time a Borrowing is repaid. The interest rate on all Borrowings
will be the one-month LIBOR rate determined the date of the Borrowing. The Borrowings may be
repaid prior to the end of the one-month LIBOR rate period. If a Borrowing is not repaid within
one month, the interest rate for such Borrowing will be adjusted to the one-month LIBOR rate 30
days after the most recent Borrowing. All payments of principal and interest shall be payable in
lawful currency of the United State of America at the office of Lender as provided above or such
other address as the holder hereof shall have designated to Borrower, in immediately available
funds. For purposes hereof, the “one-month LIBOR rate” as of any date, shall mean the rate per
month (rounded upwards, if necessary, to the nearest 1/100 of 1%) appearing on Dow Jones Markets
Page 3750 (or any successor page) as the London interbank offered rate for deposits in U.S. dollars
at approximately 11:00 a.m. (London time).

8. Prepayment. Borrower may prepay all or part of any amounts outstanding under the Loan at any
time without payment of penalty. Any partial prepayment, however, shall be applied against unpaid
installments outstanding hereunder in the inverse order of maturity beginning with the shortest
maturity and shall not be made in amounts of less than $5,000.00.

9. Default. Borrower shall be in default (“Default”) if any of the following events occur and
continue:

Page 2

 

     (a) Borrower becomes insolvent or admits in writing its inability to pay its debts as they
mature; applies for, consents to, or acquiesces in the appointment of a trustee or receiver for any
of Borrower’s property; in the absence of an application, consent, or acquiescence a trustee or
receiver is appointed for it or a substantial part of its property and is not discharged within 120
days; Borrower otherwise commits an act of bankruptcy; or any bankruptcy, reorganization, debt
arrangement, or other proceeding under any bankruptcy or insolvency law, or any dissolution or
liquidation proceeding, is instituted by or against it and if instituted is consented to or
acquiesced in by it or remains for 120 days undismissed;

     (b) Borrower defaults in the performance of the terms and conditions of this Agreement and
such default continues for 30 days after written notice thereof from Lender; or

     (c) Any government, board, agency, department, or commission takes possession or control of a
substantial part of Borrower’s property and such possession or control continues for 30 days.

10. Acceleration at Option of Lender; Cost of Enforcement. If any of the events listed in
paragraph 9(a), (b), or (c) occur and continue, Lender may declare the amounts outstanding under
this Agreement immediately due and payable, at which time all unpaid installments shall immediately
become due and payable. Lender shall promptly advise Borrower in writing of any acceleration under
this paragraph, but the failure to do so shall not impair the effect of a subsequent declaration.
Borrower agrees to pay reasonable attorneys’ fees and all other reasonable costs and expenses
incurred, after a Default, in the enforcement of this Agreement, the enforcement of any security
interest with respect to this Agreement, and the collection of amounts due hereunder, whether such
enforcement or collection is by court action or otherwise.

11. Binding Effect. This Agreement shall be binding on the respective successors and assigns of
Lender and Borrower and shall inure to the benefit of Lender’s successors and assigns.

12. Loan Expenses. Except as expressly set forth herein, Borrower shall not be required to pay any
fees or other expenses of Lender in connection with this Agreement or the Borrowings made
hereunder.

13. Commitment Fee. Borrower shall pay to Lender a commitment fee on the daily average unused
amount of the Loan for the period from and including the Effective Date up to, but excluding, the
Maturity Date at a rate of 0.25% per annum. Accrued commitment fees shall be payable quarterly in
arrears on the last day of each fiscal quarter of Borrower and on the Maturity Date. All
commitment fees shall be computed on the basis of a year of 365 days (or 366 days in a leap year)
and shall be payable for the actual number of days elapsed (including the first day but excluding
the last day).

14. Non-Waiver. No delay or failure by Lender to exercise any right under this Agreement, and no
partial or single exercise of that right, shall constitute a waiver of that or any other right,
unless otherwise expressly provided herein.

15. Governing Law. This Agreement shall be construed in accordance with and governed by the laws
of the State of New York.

16. Headings. Headings in this Agreement are for convenience only and shall not be used to
interpret or construe its provisions.

17. Counterparts and Facsimile or Electronic Signatures. This Agreement may be executed in any
number of counterparts, each of which shall be deemed an original and all of which, taken together,
shall constitute one agreement. A facsimile or electronic signature to this Agreement shall be

18. Time of Essence. Time is expressly declared to be the essence of this Agreement.

19. Entire Agreement; Modification. This Agreement and any other loan documents executed in

There are no oral agreements between the parties. This Agreement may not be modified except in a
writing signed by both parties.

20. Notices. All notices under this Agreement shall be in writing and delivered to the respective
parties at their principal offices stated at the beginning hereof.

21. No Third Party Beneficiaries. The agreement of Lender to make the Loan to Borrower for the
account of Borrower on the terms and conditions set forth in this Agreement, is solely for the
benefit of Borrower and no other person has any rights hereunder against Lender or with respect to
the extension of credit contemplated hereby.

22. UCC Waivers. Borrower waives demand for payment, presentment for payment, notice of nonpayment
or dishonor, protest and notice of protest, and agrees to any extension of time of payment and
partial payments before, at, or after maturity of the Loan. No renewal or extension of this
Agreement, no release or surrender of any security for this Agreement, no release of any person
liable hereon, no delay in the enforcement hereof, and no delay or omission in exercising any right
or power hereunder, shall affect the liability of Borrower. Each legal holder hereof shall have
and may exercise all the rights and powers given to Lender herein.

23. Special Exculpation. No claim may be made by Borrower or any other person against Lender, or
its directors, officers, employees, attorneys or agents of any of them for any special, indirect,
consequential or punitive damages in respect of any claim for breach of contract or any other
theory of liability arising out of or relating to this Agreement or any other financing document or
the transactions contemplated hereby or thereby, or any act, omission or event occurring in
connection therewith and Borrower hereby waives, releases and agrees not to sue upon any claim for
any such damages, whether or not accrued and whether or not known or suspected to exist in its
favor.

24. Waiver of Jury Trial. Each of Borrower and Lender hereby irrevocably waives, to the fullest

Page 4

 

officers, employees and agents (each an “Indemnified Party”) from and against any and all claims,
damages, liabilities and expenses (including without limitation fees and disbursements of counsel)
arising out of or in connection with any investigation, litigation or proceeding (whether or not
any Indemnified Party is a party) arising out of, related to or in connection with this Agreement,
the Borrowing made hereunder or any transaction in which any proceeds of all or any part of the
Loan are applied.

26. Severability. If any term or provision of this Agreement shall be determined to be illegal or
unenforceable, all other terms and provisions of this Agreement shall nevertheless remain effective
and shall be enforced to the fullest extent permitted by applicable law.

27. Further Assurances. The parties agree (a) to furnish upon request to each other such further
information, (b) to execute and deliver to each other such other documents, and (c) to do such
other acts and things, all as the other party may reasonably request for the purpose of carrying
out the intent of this Agreement.

28. Interest Rate Limitation. Notwithstanding anything herein to the contrary, if at any time the
interest rate applicable to any amounts outstanding hereunder, together with all fees, charges and
other amounts which are treated as interest on such amounts under applicable law (collectively the
“Charges”), shall exceed the maximum lawful rate (the “Maximum Rate”) which may be contracted for,
charged, taken, received or reserved by Lender in accordance with applicable law, the rate of
interest payable in respect of such amounts outstanding hereunder, together with all Charges
payable in respect thereof, shall be limited to the Maximum Rate and, to the extent lawful, the
interest and Charges that would have been payable in respect of such amounts outstanding but were
not payable as a result of the operation of this Section 27 shall be cumulated and the interest and
Charges payable to Lender in respect of other amounts outstanding hereunder or periods shall be
increased (but not above the Maximum Rate therefor) until such cumulated amount, together with
interest thereon at the Federal Funds Effective Rate to the date of repayment, shall have been
received by Lender. “Federal Funds Effective Rate” as used herein means, for any day, the weighted
average (rounded upwards, if necessary, to the next 1/100 of 1%) of the rates on overnight Federal
funds transactions with members of the Federal Reserve System arranged by Federal funds brokers, as
published on the next succeeding business day by the Federal Reserve Bank of New York, or, if such
rate is not so published for any day that is a business day, the average (rounded upwards, if
necessary, to the next 1/100 of 1%) of the quotations for such day for such transactions received
by Lender from three Federal funds brokers of recognized standing selected by it.

The parties have caused this Agreement to be executed by their proper officers as of the
Effective Date.
