                       ZOND-PANAERO WINDSYSTEM PARTNERS I,
                        A CALIFORNIA LIMITED PARTNERSHIP


                NOTES TO UNAUDITED CONDENSED FINANCIAL STATEMENTS


NOTE 1 - BASIS OF PRESENTATION

The condensed financial statements included herein for the quarterly periods
ended June 30, 2005 and 2004 have been prepared by Zond-PanAero Windsystem
Partners I, a California Limited Partnership (the "Partnership") without audit
pursuant to the rules and regulations of the Securities and Exchange Commission
(the "SEC"). Accordingly, these statements reflect all adjustments (consisting
only of normal recurring entries), which are, in the opinion of the Partnership,
necessary for a fair statement of the financial results for the interim periods.
Certain information and notes normally included in financial statements prepared
in accordance with accounting principles generally accepted in the United States
of America have been condensed or omitted pursuant to such accounting
principals. The Partnership believes that the information and notes included in
the financial information are adequate to make the information presented not
misleading. Operating results for the interim period presented are not
necessarily indicative of the results that may be expected for the year ended
December 31, 2005.

The preparation of financial statements in conformity with accounting principles
generally accepted in the United States of America requires management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the financial statements and the reported amounts of revenues and expenses
during the reporting period. Actual results could differ from those estimates.

NOTE 2 - THE PARTNERSHIP

Introduction

The Partnership was formed on June 29, 1984 to purchase, own and operate a
system of 300 Vestas Energy A/S Model V-15 wind turbine electric generators (the
"Turbines"). The electricity generated by the Turbines is sold by the
Partnership to its sole customer, Southern California Edison Company ("SCE").

Each Turbine has a rated capacity of 65 kilowatts, and the Turbines have an
aggregate rated capacity of 19.5 megawatts. The Turbines, together with certain
infrastructural improvements (the "Infrastructural Improvements"), which are
owned by Mesa Wind Developers ("Mesa"), a joint venture between Enron Wind
Systems, LLC ("EWS") and an affiliate of PanAero Corporation ("PanAero"), form
an integrated electric power generating facility (the "Windsystem"). The
Windsystem is located in the San Gorgonio Pass area of the San Bernardino
Mountains near Palm Springs, California (the "Operating Site").

The Turbines are interconnected by a system of transformers and power transfer
lines to a substation and SCE's transmission grid. The individual power lines
from each of the Turbines are fed into step-up transformers, which increase the

                                     Page 6




voltage from 480 volts to 12.5 kilovolts. Additional 12.5 kilovolt power
transfer lines carry electricity to a substation, which steps up the electric
power to 115 kilovolts for delivery to SCE.

EWS is an operator of commercial wind-powered electric generating facilities and
PanAero is a wind resources development company. On January 3, 1997, EWS's
parent, Zond Corporation, became a wholly-owned subsidiary of Enron Renewable
Energy Corp., which is wholly-owned by Enron Corp. ("Enron"). In May 1997, the
name of Zond Corporation was changed to Enron Wind Corp. ("EWC").

The general partner (the "General Partner") of the Partnership is Zond
Windsystems Management LLC ("ZWM"), a California limited liability company
wholly-owned by EWS. See "Bankruptcy and Mergers" regarding certain affiliated
mergers and name changes affecting ZWM, EWS and EWC. The business of the
Partnership and the respective rights of its partners, including the
Partnership's limited partners (the "Limited Partners"), are governed by the
First Amended and Restated Certificate and Agreement of Limited Partnership of
Zond-PanAero Windsystem Partners I, a California Limited Partnership, entered
into on November 29, 1984, as amended (the "Partnership Agreement").

The Windsystem, which became operational in November 1984, was constructed by
Mesa Construction Company ("MCC"), a joint venture between an affiliate of EWS
and an affiliate of PanAero. The Partnership paid MCC a total of $48.9 million
for the purchase, construction and installation of the Turbines, comprised of
$22.4 million in cash and $26.5 million in the form of eighteen-year, 13% notes
payable in equal semi-annual installments of principal and interest totaling
$1.9 million (the "Purchase Notes"). As of June 30, 2005, the Partnership was in
default of the Purchase Notes. See Notes 3 and 4 below.

The term of the Partnership ends on December 31, 2005, unless terminated earlier
in accordance with the terms of the Partnership Agreement. The Partnership will
dissolve effective on the day on which the term of the Partnership ends. Upon
the dissolution of the Partnership, the General Partner will liquidate the
assets of the Partnership, apply and distribute the proceeds thereof as
contemplated by the Partnership Agreement, and cause the cancellation of the
Partnership's Certificate of Limited Partnership with the Secretary of State of
the State of California. The Partnership will then terminate and the General
Partner will file with the SEC a Form 15 to terminate registration of the Units
under the Securities Exchange Act of 1934, as amended (the "Exchange Act"). In
anticipation of the dissolution of the Partnership on December 31, 2005, the
General Partner is evaluating the options in connection with the liquidation of
the Partnership's assets. See "Substantial Transactions and Operating
Agreements" below.

Bankruptcy and Mergers

Commencing on December 2, 2001, and periodically thereafter, Enron and certain
of its subsidiaries filed voluntary petitions for relief under Chapter 11 of the
United States Bankruptcy Code (the "Bankruptcy Code"). This matter is referred
to herein as the "Enron Bankruptcy". On February 20, 2002, EWC and Enron Wind
Systems, Inc. ("EWSI") each filed a voluntary petition for relief under Chapter
11 of the Bankruptcy Code. Additionally, two California limited liability
companies formed on February 19, 2002 for the purposes of merging with EWC and
EWSI in anticipation of the sale of Enron's wind turbine manufacturing business
also filed voluntary petitions for relief under Chapter 11 of the Bankruptcy
Code.


                                     Page 7



EWC merged with and into one of such limited liability companies on April 19,
2002 and the surviving limited liability company changed its name to Enron Wind
LLC ("EW"). EWSI merged with and into the other limited liability company, also
on April 19, 2002, and the surviving limited liability company changed its name
to Enron Wind Systems, LLC.

On April 12, 2002, Zond Windsystems Management Corporation ("ZWMC"), the general
partner of the Partnership at such time, merged with and into a third California
limited liability company, formed on March 12, 2002, and the surviving limited
liability company changed its name to Zond Windsystems Management LLC. On May 3,
2002, Zond Construction Corp. merged with and into a fourth California limited
liability company, formed on March 21, 2002, and the surviving limited liability
company changed its name to Zond Construction LLC ("ZC"). ZC is a joint venture
partner in MCC. Neither ZWM nor ZC has filed for bankruptcy.

On November 17, 2004, the Chapter 11 Plan (the "Plan") relating to the Enron
bankruptcy became effective. The Plan provides for Enron and its affiliated
debtor companies (including EWS and EW) to sell most of their assets and
distribute to their creditors the proceeds of such sales. In connection with the
Plan, EWS assumed the Management Agreement (as defined in "Operation and
Maintenance Services" below) and that agreement remains in effect.

Substituted Limited Partner

PanAero Management Corporation ("PAMC"), a California corporation wholly-owned
by PanAero, formerly served as a general partner of the Partnership. In June
1988, the Partnership solicited a vote by proxy of the Limited Partners to
remove PAMC as a general partner. Pursuant to that vote, PAMC was converted to a
substituted limited partner. Although the term "Substituted Limited Partner" is
defined in the Partnership Agreement as any individual, partnership,
corporation, trust or other entity admitted to the Partnership as a Limited
Partner pursuant to transfer provisions under the Partnership Agreement, the
term substituted limited partner is used in the accompanying Condensed Balance
Sheets at June 30, 2005 (Unaudited) and December 31, 2004 and the Unaudited
Condensed Statements of Changes in Partners' Deficit for the six months ended
June 30, 2005 in reference to the substituted limited partner interest created
by the removal of PAMC as a general partner. Under an Agreement of Settlement
and Mutual Releases executed on June 26, 2000, PAMC agreed to transfer its
substituted limited partner interest in the Partnership to ZWMC.

Sale to General Electric

On April 10, 2002, Enron, EWC and certain of its subsidiaries, including EWSI,
entered into an Amended and Restated Purchase and Sale Agreement in which such
entities agreed to sell in an asset sale (the "GE Sale") their wind turbine
manufacturing, operation and maintenance and construction businesses to General
Electric Company, acting through its GE power systems business ("GEPS"). The GE
Sale was consummated on May 10, 2002. EW and its subsidiary companies retained
its existing wind power projects including the indirect ownership of the general
partnership interest in the Partnership. However, effective as of the sale,
substantially all of the employees who had been involved in the management of
the Partnership transferred to GEPS.

Following the sale to GEPS, certain Enron personnel who were not formerly
involved with the management of operations of the Partnership were appointed to
manage and operate the Partnership, and ZWM's principal executive offices were


                                     Page 8



moved to 1400 Smith Street, Houston, Texas 77002. In March 2004, the principal
executive offices were moved to 1221 Lamar Street, Suite 1600, Houston, Texas
77010.

Operation and Maintenance Services

EWS manages the Windsystem pursuant to a windsystem management agreement with
the Partnership executed on July 27, 1988 (the "Management Agreement"). The
Management Agreement by its terms was to terminate on June 23, 2005; however,
the Partnership and EWS entered into a Fourth Amendment to Windsystem Management
Agreement (the "Management Agreement Amendment") which was effective as of June
23, 2005 and which extended the termination date of the Management Agreement
from June 23, 2005 to December 31, 2005. See Note 3 for additional information.

Prior to May 10, 2002, Enron Wind Maintenance LLC, an affiliate of EWS, provided
operation and maintenance services for the Windsystem. On May 10, 2002, EWS
contracted with GE Wind Energy, LLC to perform certain operation and maintenance
services relating to the Windsystem for a period of one year ending on May 10,
2003.

In April 2003, EWS entered into an agreement (the "O&M Agreement") with SeaWest
Asset Management Services, LLC ("SeaWest") to provide certain operation and
maintenance services relating to the Windsystem for a 5-year period ending on
May 10, 2008. If EWS terminates the O&M Agreement prior to the end of its stated
term, EWS may be required to pay certain agreed demobilization fees to SeaWest.
If EWS is required to pay such fees, EWS may attempt to seek recovery from the
Partnership of some, or all, of the amount of such fees pursuant to the terms of
the Management Agreement. Management currently estimates that the amount of the
demobilization fee, if any, for which EWS may seek recovery from the Partnership
would not be in excess of approximately $72,000.

Substantial Transactions and Operating Agreements

The accompanying unaudited condensed financial statements include substantial
transactions with related parties. These transactions are further described in
Notes 4 and 5.

A summary of the major operating agreements entered into by the Partnership,
directly or indirectly, is set forth below:

(1)  Through June 23, 2005 the Partnership sold the electricity produced by the
     Turbines to SCE pursuant to a power purchase and sales agreement (the
     "Power Agreement") that was originally entered into between SCE and PanAero
     in April 1982 and covered an aggregate of 29.9 megawatts of generating
     capacity. PanAero assigned the Power Agreement to Mesa in July 1984. Mesa
     subsequently assigned the portion of the Power Agreement that covers the
     aggregate rated capacity of the Turbines (19.5 megawatts) to the
     Partnership pursuant to that certain Partial Assignment of Wind Park Power
     Purchase and Sales Agreement dated September 28, 1984 (the "Partial
     Assignment"). Each of the Partial Assignment and the Power Agreement
     terminated by its terms on or about June 23, 2005.

     On or about June 23, 2005, the Partnership and PAMC entered into a
     Reservation of Rights Agreement dated as of June 23, 2005 (the "Reservation
     of Rights Agreement") pursuant to which the Partnership is permitted to (i)


                                     Page 9


     sell power to SCE from the Windsystem under a Reformed Standard Offer 1
     As-Available Capacity and Energy Power Purchase Agreement dated June 23,
     2005 between SCE and PAMC (the "RSO1 Power Agreement"), and (ii)
     interconnect the Windsystem with SCE's transmission system under an
     Interconnection Facilities Agreement between SCE and PAMC which was
     effective as of June 23, 2005 (the "Interconnection Agreement").

     Under the Reservation of Rights Agreement, the Partnership is permitted and
     has agreed to deliver up to 19.5 megawatts of energy to SCE under the RSO1
     Power Agreement and to interconnect the Partnership's Windsystem to SCE's
     transmission system under the Interconnection Agreement. The Reservation of
     Rights Agreement terminates on December 31, 2005, unless terminated earlier
     by the Partnership upon 30 days advance notice to PAMC. The Partnership is
     not required under the Reservation of Rights Agreement to pay to PAMC a fee
     for the Partnership's use of the RSO1 Power Agreement or the
     Interconnection Agreement. The Partnership is required to pay for a portion
     of all fees, costs and expenses incurred by PAMC under the RSO1 Power
     Agreement and the Interconnection Agreement, including, without limitation,
     interconnection fees, back feed electricity costs and maintenance costs.
     The portion of such fees, costs and expenses to be paid by the Partnership
     is based on the ratio of (x) the aggregate installed name-plate capacity of
     the Partnership's Windsystem to (y) the aggregate installed name-plate
     capacity of all the wind power projects delivering power to SCE under the
     RSO1 Power Agreement.

     PAMC also concurrently entered into a separate reservation of rights
     agreement with Zond-PanAero Windsystem Partners II, a California limited
     partnership ("ZWP II") and an affiliate of the Partnership, pursuant to
     which PAMC granted ZWP II the right to sell to SCE under the RSO1 Power
     Agreement up to 10.4 megawatts of energy from its wind turbine electric
     power generation facility and to interconnect such wind power generation
     facility to SCE's transmission grid under the Interconnection Agreement.

     Under the RSO1 Power Agreement, SCE is required to purchase from PAMC, and
     PAMC is required to sell to SCE, the output from the Partnership's
     Windsystem and ZWP II's wind power facility, provided that the aggregate
     name-plate capacity of all such generating facilities may not exceed 30
     megawatts at any one time. The RSO1 Power Agreement has a five-year term,
     but may be terminated by PAMC upon 30 days advance notice to SCE. The price
     to be paid by SCE for the energy delivered under the RSO1 Power Agreement
     is equal to the short run avoided cost to SCE for energy during the
     delivery period of such energy. Under the RSO1 Power Agreement, SCE will
     also pay an annual capacity payment for the installed capacity of such
     generation facilities that is based on SCE's avoided cost for capacity.

     Unlike the Power Agreement, which terminated on or about June 23, 2005, the
     RSO1 Power Agreement does not contain a minimum energy price payable by
     SCE. The minimum price for energy that was paid by SCE under the Power
     Agreement was $0.102 per kilowatt hour of energy. As a result, the
     Partnership expects less revenue from the sale of energy under the RSO1
     Power Agreement as compared with the sale of an equal amount of energy
     under the Power Agreement.

     Under the Interconnection Agreement, PAMC and the other sellers under the
     RSO1 Power Agreement are permitted to interconnect up to an aggregate of 30
     megawatts of generating capacity to SCE's transmission grid at the existing


                                    Page 10



     SCE substation located at the Windsytem site. The Interconnection Agreement
     requires PAMC to pay to SCE a monthly interconnection fee of $8,265. The
     Interconnection Agreement terminates upon the termination of the RSO1 Power
     Agreement.

(2)  Since July 1988, the Partnership has contracted with EWS (or its
     predecessor) for the operation and maintenance of the Turbines and the
     performance of certain ancillary management services, such as collection of
     revenues from SCE and the administration and payment of all Partnership
     expenses. Under the provisions of the Management Agreement, the Partnership
     pays a management fee of 2% of the Partnership's Gross Operating Proceeds.
     "Gross Operating Proceeds" is defined as all gross receipts from the sale
     of electricity generated by the Turbines and all amounts paid in lieu of
     receipts from the sale of electricity, including, without limitation, any
     proceeds of systems performance or wind resource insurance, casualty loss
     and business interruption insurance paid in reimbursement of lost revenues
     and warranty payments in reimbursement of lost revenues. Under the
     Management Agreement, EWS is entitled to be reimbursed for 115% of the
     maintenance costs, including labor and material costs that it incurs in the
     performance of maintenance services, including maintenance services
     performed by third parties relating to the Windsystem. The term of the
     Management Agreement ends on December 31, 2005. See Note 5 for additional
     information.

(3)  The Operating Site is situated on two adjoining parcels of land, consisting
     of approximately 440 acres, located in the San Gorgonio Pass area of the
     San Bernardino Mountains approximately 16 miles northwest of Palm Springs,
     California. The Partnership owns the Turbines, including the supporting
     towers and related concrete support pads and controllers. The Partnership
     uses the Infrastructural Improvements and a portion of the Operating Site
     pursuant to an easement granted by Mesa under the terms of a Wind Park
     Easement Agreement dated as of September 7, 1984, as amended (the "Wind
     Park Easement Agreement"). The Infrastructural Improvements include roads,
     fences, power transfer system, substation and maintenance facilities. Mesa
     has title to the Infrastructural Improvements, but has granted the
     Partnership a security interest in such assets under the Wind Park Easement
     Agreement. The Infrastructural Improvements are also utilized by ZPII under
     a similar arrangement with Mesa.

     Mesa has rights to develop wind energy resources at the Operating Site,
     which includes the Infrastructural Improvements, under a right-of-way grant
     (the "Right-of-Way Grant") from the United States Bureau of Land Management
     ("BLM"). The Right-of-Way Grant was originally issued to PanAero on January
     26, 1983, and was assigned by PanAero to Mesa in April 1984. The primary
     term of the Right-of-Way Grant expired on January 26, 2003. On December 19,
     2002, the Right-of-Way Grant was extended for a ten-year period commencing
     on January 27, 2003.

     The Wind Park Easement Agreement, as previously amended, was to terminate
     on June 23, 2005. The Partnership and Mesa entered into the Amendment to
     Wind Park Easement Agreement (the "Easement Amendment") which was effective
     as of June 23, 2005 and which extended the termination date of the Wind
     Park Easement Agreement from June 23, 2005 to December 31, 2005.

     At the termination of the Wind Park Easement Agreement, the Partnership
     may: (1) elect to abandon the Turbines, (2) at its own expense, remove the
     Turbines, or (3) elect to sell the Turbines. If the Partnership elects to


                                    Page 11



     sell the Turbines at any time, the Partnership must first offer the
     Turbines to Mesa on the same terms and conditions. If the Partnership
     abandons the Turbines, neither Mesa nor any affiliate shall have the right
     to operate the Turbines unless Mesa pays to the Partnership the appraised
     fair market value (as defined) of the Turbines. The General Partner is in
     the process of evaluating the Partnership's options under the Wind Park
     Easement Agreement upon termination.

     EWSI, PanAero, and their affiliates have developed and sold additional wind
     turbines on the Operating Site to ZPII and Mesa has granted a similar
     easement to ZPII.

     Under the Wind Park Easement Agreement, Mesa charges the Partnership
     easement fees for the use of the Operating Site and Infrastructural
     Improvements in an amount equal to the greater of 5% of Gross Operating
     Proceeds or the Partnership's pro rata share (with the other producers of
     electric energy from wind power on the Operating Site) of the payments due
     the BLM under the Right-of-Way Grant. See Note 5 for additional
     information.

Cash Distributions

The Partnership distributes cash in accordance with the terms of the Partnership
Agreement. Due to less-than-projected operating results, the Partnership has not
distributed any cash during any fiscal year other than 1985, in which the
Partnership distributed an aggregate of approximately $158,000 to the Limited
Partners and $2,000 to the then General Partners. Under the Purchase Notes, the
Partnership cannot make cash distributions to its partners unless certain cash
reserve balances are maintained, no events of default exist, and certain ratio
tests are met. The Partnership has not met these criteria since 1985 and did not
make cash distributions to its partners during the six month periods ended June
30, 2005 or June 30, 2004.

SCE Curtailment

SCE substantially curtailed the Partnership's electrical production from the
Windsystem from April 13, 2004 through May 17, 2004 (the "SCE Curtailment").
During this period, SCE curtailed the Partnership's production of electric power
by approximately 75% resulting in the Partnership's inability to produce and
sell a significant portion of electric power. By letter dated June 22, 2004,
Enron Wind LLC, on behalf of the sellers under the Power Agreement, issued for
payment an invoice to SCE in the amount of approximately $750,000 to compensate
the Partnership and ZP II for their estimated losses during the SCE Curtailment.
Of the approximately $750,000 invoiced to SCE, approximately $482,000 represents
lost revenue that otherwise would have been paid to the Partnership. By letter
dated September 22, 2004, SCE informed Enron Wind LLC that the SCE Curtailment
was in compliance with all applicable power purchase agreements, and that SCE
would not reimburse any projects, including the Partnership, for any revenues
that may have been lost during the SCE Curtailment. As a result, none of the
amount invoiced to SCE has been recorded as revenue for the Partnership.

NOTE 3 - GOING CONCERN

The following matters raise substantial doubt about the Partnership's ability to
continue as a going concern:

     1.   The Purchase Notes matured on December 31, 2002 and all of the accrued
          and unpaid interest and outstanding principal on the Purchase Notes


                                    Page 12



          was due on that date. As discussed in Note 4 below, the Partnership
          has not had, and does not anticipate that it will have, sufficient
          cash flows from operations to make scheduled payments of interest in
          arrears on the Purchase Notes. Accordingly, the Partnership is in
          default of the Purchase Notes. Upon notice of default, MCC has a right
          to foreclose against its security interests in the assets of the
          Partnership. As of August 15, 2005, MCC has not notified the
          Partnership of its intent to foreclose on its security interest. Any
          such foreclosure by MCC on its security interests in the assets of the
          Partnership would have a material adverse effect on the Partnership.

     2.   As discussed in Note 2 above, the term of the Partnership ends on
          December 31, 2005, unless terminated earlier in accordance with the
          terms of the Partnership Agreement. The Partnership will dissolve
          effective on the day on which the term of the Partnership ends. Upon
          the dissolution of the Partnership, the General Partner will liquidate
          the assets of the Partnership, apply and distribute the proceeds
          thereof as contemplated by the Partnership Agreement, and cause the
          cancellation of the Partnership's Certificate of Limited Partnership
          with the Secretary of State of the State of California. The
          Partnership will then terminate and the General Partner will file with
          the Commission a Form 15 to terminate registration of the Units under
          the Exchange Act.

NOTE 4 - PURCHASE NOTES

Under an agreement reached in April 1989, MCC reduced the interest rate on the
Purchase Notes from 13% to 11% per annum effective in January 1990. The
Partnership secured its payment obligations under the Purchase Notes by granting
MCC security interests in the Turbines and other collateral, including the
rights, title and interests of the Partnership under several of the
Partnership's major operating agreements.

The Purchase Notes matured in December 31, 2002. The Partnership has not had,
and may not have, sufficient cash flows from operations to make all payments of
interest on the Purchase Notes. The Partnership is in default under the terms of
the Purchase Notes. During the first six months of 2005, the Partnership made
payments of $1.9 million which were applied towards the accrued and unpaid
interest. As of June 30, 2005, the amount in default was $2.4 million, which was
comprised solely of interest in arrears. Under the terms of the Purchase Notes,
payments made by the Partnership are applied towards principal and then towards
accrued and unpaid interest. The terms of the Purchase Notes do not require that
the Partnership pay additional interest on the accrued and unpaid interest due
under the Purchase Notes. Upon notice of default, MCC has a right to foreclose
against its security interest in all the assets of the Partnership, including
the Turbines. As of August 15, 2005, MCC has not notified the Partnership of its
intent to foreclose on its security interests. Any such foreclosure by MCC on
its security interests in the assets of the Partnership would have a material
adverse effect on the Partnership.

NOTE 5 - TRANSACTIONS WITH RELATED PARTIES

In addition to the Purchase Notes (See Note 4 above) the Partnership had amounts
payable to Mesa and EWS, respectively as of June 30, 2005. Amounts payable to
Mesa include easement fees and other miscellaneous expenses related to
Windsystem operations. Amounts payable to EWS include management fees,
maintenance costs and other miscellaneous expenses related to Windsystem
operations.

The Partnership has the following related party transactions and relationships:


                                    Page 13



(1)  Mesa assigned easement rights to a portion of the Operating Site and
     granted rights to use the Infrastructural Improvements to the Partnership
     under the Wind Park Easement Agreement (See Note 2 above). The Partnership
     paid $0.05 million in easement fees during the second quarter of 2005 as
     compared to $0.03 million during the second quarter of 2004 pursuant to the
     Wind Park Easement Agreement.

(2)  The Partnership has a contract with EWS to operate and maintain the
     Turbines and to perform certain management and administrative services
     under the Management Agreement (See Note 2 above). The Partnership incurred
     expenses of $0.2 million during both the second quarter of 2005 and the
     second quarter of 2004, respectively, pursuant to the Management Agreement.

In 1988, Mesa assigned $581,000 of receivables from the Partnership to each of
its partners, EWS and an affiliate of PanAero. EWS subsequently forgave its
$581,000 of receivables from the Partnership. This forgiveness was treated as a
capital contribution in the accompanying financial statements.

NOTE 6 - COMMITMENTS AND CONTINGENCIES

Future annual minimum payments under non-cancelable obligations as of June 30,
2005 are $0.2 million. There are no lease obligations subsequent to December 31,
2005.

NOTE 7 - SUBSEQUENT EVENTS

SCE Curtailment

The Partnership is currently considering its options relating to SCE's refusal
to compensate the Partnership for its lost revenues resulting from the SCE
Curtailment. See Note 2, SCE Curtailment, above.

Item 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
        CONDITION AND RESULTS OF OPERATIONS

Going Concern

The following matters raise substantial doubt about the Partnership's ability to
continue as a going concern:

1.   The Purchase Notes matured on December 31, 2002 and all of the accrued and
     unpaid interest and outstanding principal on the Purchase Notes was due on
     that date. As discussed in Note 4 to the Financial Statements, the
     Partnership has not had, and does not anticipate that it will have,
     sufficient cash flows from operations to make scheduled payments of
     interest in arrears on the Purchase Notes. Accordingly, the Partnership is
     in default of the Purchase Notes. Upon notice of default, MCC has a right
     to foreclose against its security interests in all the assets of the
     Partnership. As of August 15, 2005, MCC has not notified the Partnership of
     its intent to foreclose on its security interest. Any such foreclosure by
     MCC on its security interests in the assets of the Partnership would have a
     material adverse effect on the Partnership.

2.   As discussed in Note 2 to the Financial Statements, the term of the
     Partnership ends on December 31, 2005, unless terminated earlier in
     accordance with the terms of the Partnership Agreement. The Partnership
     will dissolve effective on the day on which the term of the Partnership
     ends. Upon the dissolution of the Partnership, the General Partner will
     liquidate the assets of the Partnership, apply and distribute the proceeds
     thereof as contemplated by the Partnership Agreement, and cause the
     cancellation of the Partnership's Certificate of Limited Partnership with
     the Secretary of State of the State of California. The Partnership will
     then terminate and the General Partner will file with the Commission a Form
     15 to terminate registration of the Units under the Exchange Act.

Liquidity and Capital Resources

The Partnership continued to experience a lack of liquidity throughout the
second quarter of 2005, primarily due to an ongoing shortfall in revenues from
operations in comparison to the costs and expenses of operations. As a result,
interest payments on the Purchase Notes in the aggregate amount of $2.4 million
were in arrears as of June 30, 2005. The Partnership's failure to make timely
payments on the Purchase Notes gave MCC the right to foreclose against its
security interest in all the assets of the Partnership, including the Turbines.
MCC has not exercised its right to foreclosure under the Purchase Notes. See
"Results of Operations for the Six months Ended June 30, 2005 Compared to the
Six months Ended June 30, 2004".

The Partnership's primary source of revenues and liquidity to fund operations of
the Windsystem, repay debt, administer the Partnership, and make distributions
to its partners is the production and sale of electricity from the Windsystem.
The Partnership's sole customer is SCE. The price paid by SCE for the
electricity is contractually defined under the RSO1 Power Agreement.

As of June 30, 2005, the Partnership had no current or planned commitments for
capital expenditures.


                                    Page 15



Results of Operations for the Six Months Ended June 30, 2005 Compared to the Six
Months Ended June 30, 2004

During the first six months of 2005, the Partnership's electricity revenue was
$2.1 million, and the Windsystem produced 21.3 million kWh of electricity sold
to SCE. This was an increase of $0.3 million or 13% in revenue and an increase
of 3.0 million kWh or 16% of electricity produced as compared to the first six
months of 2004. The increase was primarily due to the effect of the SCE
Curtailment on the Partnership's electricity sales during the first six months
of 2004. There were no curtailments during the first six months of 2005.

Costs and expenses in the first six months of 2005 were $0.7 million, a decrease
of $1.4 million or 65%, as compared to the first six months of 2004.
Depreciation decreased $1.2 million during the first six months of 2005 as
compared to the first six months of 2004 as the Turbines were fully depreciated
in 2004. The Partnership is continuing to depreciate other assets, including the
building and relocation/upgrades on the Turbines. Property taxes were $0.05
million lower during the first six months of 2005 as compared to the first six
months of 2004 due to penalties and interest which were assessed during the
first six months of 2004 relating to the late payment of property taxes. No such
assessments were made during the first six months of 2005.

Easement fees and management fees remained constant during the first six months
of 2005 as compared to the first six months of 2004. Easement and management
fees are calculated as a percentage of Gross Operating Proceeds. "Gross
Operating Proceeds" is defined as all gross receipts from the sale of
electricity generated by the Turbines and all amounts paid in lieu of receipts
from the sale of electricity, including, without limitation, any proceeds of
systems performance or wind resource insurance, casualty loss and business
interruption insurance paid in reimbursement of lost revenues and warranty
payments in reimbursement of lost revenues. Maintenance expenses decreased $0.05
million in the first six months of 2005, as compared to the first six months of
2004, due to a decrease in unscheduled maintenance. Insurance costs decreased by
$0.03 million in the first six months of 2005 due to a decrease in premiums as
compared with the first six months of 2004. Other operating costs decreased
$0.02 million in the first six months of 2005 due to a decrease in the use of
outside consultants as compared to the same period in 2004.

Overall, the Partnership reported net income of $1.4 million for the first six
months of 2005 as compared with a net loss of $0.2 million for the first six
months of 2004. During the first six months of 2005, the total partners' deficit
decreased $1.4 million to $0.0 million. The net income per Unit was $1,178 for
the first six months of 2005 compared with a net loss per Unit of $197 for the
first six months of 2004.

Cash flows from operations decreased $0.03 million in the first six months of
2005 as compared to the first six months of 2004. This decrease was primarily
due to unfavorable changes in working capital during the first six months of
2005 as compared to the first six months of 2004. Cash flows used in financing
activities decreased by $0.5 million due to principal payments made on the
Purchase Notes during the six months ended June 30, 2004, while none were made
during the six months ended June 30, 2005. Excess cash flows from operations are
used primarily to fund payments of the interest in arrears on the Purchase
Notes.


                                    Page 16



Results of Operations for the Three Months Ended June 30, 2005 Compared to the
Three Months Ended June 30, 2004

For the three months ended June 30, 2005, revenues from power sales were $1.4
million, and the Windsystem produced 14.7 million kWh of electricity for sale to
SCE. This was an increase of $0.2 million or 17% in revenue and an increase of
2.6 million kWh of electricity produced or 21% as compared to the same period in
2004.

Costs and expenses for the second quarter of 2005 were $0.4 million. This was a
decrease of $0.5 million or 56%, as compared to the second quarter of 2004.
Depreciation decreased $0.6 million during the second quarter of 2005 as
compared to the second quarter of 2004 as the Turbines were fully depreciated in
2004. The Partnership is continuing to depreciate other assets, including the
building and relocation/upgrades on the Turbines. Property taxes were constant
during the second quarter of 2005 as compared to the second quarter of 2004.

Easement fees and management fees increased $0.02 and $0.01 million,
respectively, during the second quarter of 2005 as compared to the second
quarter of 2004. Easement and management fees are calculated as a percentage of
Gross Operating Proceeds. Maintenance expenses increased $0.01 million in the
second quarter of 2005, as compared to the second quarter of 2004, due to an
increase in unscheduled maintenance. Insurance costs decreased by $0.01 million
in the second quarter of 2005 due to a decrease in premiums as compared with the
second quarter of 2004. Other operating costs increased $0.05 million in the
second quarter of 2005 due to an increase in the use of outside consultants as
compared to the same period in 2004.

Overall, the Partnership reported net income of $1.0 million for the second
quarter of 2005, which is an increase of $0.7 million or 233% as compared to the
second quarter of 2004. Net income per Unit was $860 for the second quarter of
2005 compared with a net income per Unit of $237 for the second quarter of 2004.

Item 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The Partnership's management with the participation of the General Partners'
Chief Executive Officer and Chief Financial Officer has evaluated the disclosure
requirements of Item 305 of Regulation S-K "Quantitative and Qualitative


                                    Page 17



Disclosures about Market Risk," and has concluded that the Partnership currently
has no market risk sensitive instruments for which this disclosure is required.

Item 4. CONTROLS AND PROCEDURES

The term "disclosure controls and procedures" is defined in Rules 13a-15(e) and
15d-15(e) of the Exchange Act. This term means controls and other procedures of
a company that are designed to ensure that information required to be disclosed
by the company in the reports that it files or submits under the Exchange Act is
recorded, processed, summarized and reported, within the time periods specified
in the SEC's rules and forms. Disclosure controls and procedures include,
without limitation, controls and procedures designed to ensure that information
required to be disclosed by a company in the reports that it files or submits
under the Exchange Act is accumulated and communicated to the company's
management, including its principal executive and principal financial officers,
or persons performing similar functions, as appropriate to allow timely
decisions regarding required disclosure.

The Partnership's management, with the participation of the General Partner's
Chief Executive Officer and Chief Financial Officer, has evaluated the
effectiveness of the Partnership's disclosure controls and procedures as of June
30, 2005. Based on these evaluations, the General Partner's Chief Executive
Officer and Chief Financial Officer concluded that the Partnership's disclosure
controls and procedures were effective as of June 30, 2005.

During the six months ended June 30, 2005, the Partnership made no change in its
internal control over financial reporting that materially affected, or is
reasonably likely to materially affect, its internal control over financial
reporting.
