Item 1.01.  Entry into a Material Definitive Agreement.
            ------------------------------------------

     As previously reported in the Quarterly Report on Form 10-Q for the
fiscal quarter ended June 30, 2006 of Zond Windsystem Partners, Ltd., Series
85-B, a California Limited Partnership (the "Partnership"), Enron Wind Systems,
LLC ("EWS") and Southern California Edison Company ("SCE") entered into a
Settlement Agreement and Release of Claims dated as of August 11, 2006 (the "SCE
Settlement Agreement"), pursuant to which, in consideration for the payment by
EWS of amounts overpaid by SCE under the Power Purchase Agreement dated as of
June 22, 1984, as amended, between SCE and the Partnership (the "85-B Power
Agreement"), plus applicable interest, as agreed between the parties, SCE agreed
to release EWS, the Partnership and Zond Windsystem Partners, Ltd., Series 85-A,
a California Limited Partnership ("Series 85-A"), among others, from liability
associated with such overpayments. The SCE Settlement Agreement was approved by
the United States Bankruptcy Court for the Southern District of New York on
August 24, 2006. The releases provided by SCE under the Settlement Agreement
became effective on September 8, 2006, the date on which EWS made a payment
to SCE of $7 million pursuant to the terms of the Settlement Agreement.

     In 1996, the Partnership had informed the Partnership's limited
partners that it was reviewing the payments received from SCE in 1996 for energy
delivered under the 85-B Power Agreement in the context of the Partnership's
contractual rights, and due to the apparent uncertainty concerning this issue,
the Partnership recognized the difference between the cash received by the
Partnership applicable to the windsystem under the fixed rate of the 85-B Power
Agreement and the avoided cost variable rates during the year ended December 31,
1996 (approximately $3.9 million) as deferred revenue (the "Deferred Energy
Revenue"). The Deferred Energy Revenue was segregated from the Partnership's
operating cash account and was not recognized as income. In connection with
discussions with SCE, it was further discovered that from January 1996 through
June 2006, SCE made capacity payments under the 85-B Power Agreement in the
amount of approximately $628,000 in excess of the amounts required to be paid
under the 85-B Power Agreement. Of this amount, approximately $589,000 related
to and was retained by the Partnership (the "Excess Capacity Revenue"). Prior to
September 8, 2006, the Deferred Energy Revenue, related accrued interest and the
Excess Capacity Revenue were classified as deferred revenue in the Partnership's
financial statements. Effective September 8, 2006, in conjunction with the
releases provided by SCE, as discussed above, this deferred revenue of
approximately $4.7 million will be recognized as other income in the
Partnership's financial statements.

     There is no assurance that regulators or other governmental authorities
will not make certain assertions related to this matter, including that a
violation of law has occurred, or take some type of action against the
Partnership or others associated with these events. At this time, the
Partnership is unable to determine whether, and to what extent, the Partnership
has financial exposure related to any such potential claims, assertions or
actions, and the Partnership reserves all of its rights and defenses associated
therewith. Therefore, the Partnership is unable to predict the ultimate outcome
this matter may have on the Partnership's financial position, results of
operations or cash flows.

Item 1.02.  Termination of a Material Definitive Agreement.
            ----------------------------------------------

     On September 8, 2006, the Partnership sold substantially all of its
