               APPLICATION FOR ORDER DECLARING THAT SEMPRA ENERGY
                  RESOURCES IS NOT AN ELECTRIC UTILITY COMPANY
                        PURSUANT TO SECTION 2(a)(3)(A) OF
                 THE PUBLIC UTILITY HOLDING COMPANY ACT OF 1935

                 Introduction and Request For Commission Action

     Sempra Energy Resources ("SER") seeks in this Application an order of the
Securities and Commission and Exchange Commission ("Commission") pursuant to
Section 2(a)(3)(A) of the Public Utility Holding Company Act of 1935, as amended
(the "Act"), declaring SER not to be an electric utility company, as defined in
Section 2(a)(3)  SER will for a brief period directly own a leasehold
interest in and operate facilities used to generate and transmit electric energy
for sale. However, as required by Section 2(a)(3)(A), SER is primarily engaged
in one or more businesses other than that of an electric utility company and
will sell only a small amount of electric energy using these generation and
transmission facilities. SER will transfer its interest in the electric
generation facilities in question and associated interconnecting transmission
facilities to another entity upon the issuance of necessary approvals from the
Federal Energy Regulatory Commission ("FERC"). SER thus requires the exemption
it seeks in this Application only on a temporary basis.

Item 1. Description of Proposed Transaction
        -----------------------------------

     SER is a wholly-owned subsidiary of Sempra Energy Solutions, a wholly-owned
subsidiary of Sempra Energy Global Enterprises, which, in turn, is wholly owned
by Sempra Energy ("Sempra"), a California holding company exempt from regulation
under section 3(a)(1) of the Act.1  Sempra has four public utility company
subsidiaries, San Diego Gas & Electric Company, Southern California Gas Company,
Frontier Energy LLC, and Bangor Gas Company LLC.

     SER develops and acquires power plants for the competitive market. All of
these projects are owned and operated by subsidiaries and affiliates of SER that
are exempt wholesale generators ("EWGs") under Section 32 of the Act. SER also
engages in substantial power marketing and other non-utility energy-related
activities. It has entered a 10-year, 4-month contract with the California
Department of Water Resources under which SER will sell up to 1,900 megawatts
("MW") of electric energy from its projects, market sources and/or a combination
of its projects and market sources.

     Among the projects SER is developing is the Mesquite Power Project located
near Phoenix, Arizona (the "Mesquite Project"). The Mesquite Project is
comprised of generating facilities with a capacity of approximately 1,250 MW and
associated transmission facilities used to interconnect the project with the
transmission grid. It is nominally owned by Wells Fargo Bank Northwest, N.A., as
trustee under a synthetic lease financing arrangement with several commercial
lenders. The interests these companies hold in the Mesquite Project are entirely

                                       2



passive. SER is the project lessee under the synthetic lease arrangement. SER
intends to transfer its leasehold interest in the Mesquite Project to its
wholly-owned subsidiary, Mesquite Power, LLC ("Mesquite Power"), an EWG.2
Included among the assets that comprise the leasehold interest are two step-up
transformers that become FERC jurisdictional once they are placed in service.
Accordingly, SER and Mesquite Power are seeking approval from FERC under Section
203 of the Federal Power Act to effectuate the intracorporate transfer of those
limited jurisdictional assets.3  However, SER expects that the Mesquite Project
will begin commercial operations on or about May 21, 2003, and it is unlikely
that the necessary FERC approval will have been received by that time. SER
expects to receive the FERC approval in due course and anticipates that it will
serve as both lessee and operator of the Mesquite Project for a period not to
exceed one month.

Item 2. Fees, Commissions and Expenses
        ------------------------------

     SER will state the estimated fees, commissions and expenses to be paid or
incurred in connection with the proposed transactions in an amendment to this
Application.

Item 3. Applicable Statutory Provisions
        -------------------------------

     Section 2(a)(3)(A) of the Act provides that the Commission may declare that
a company which owns or operates electric utility facilities is not an "electric
utility company" if it finds that "such company is primarily engaged in one or
more businesses other than the business of an electric utility company, and by
reason of the small amount of electric energy sold by such company it is not
necessary in the public interest or for the protection of investors or consumers
that such company be considered an electric utility company [under the Act]."
Rule 10(a)(1) under the Act exempts from the duties and obligations imposed upon
a "holding company," as defined in Section 2(a)(7) of the Act, any company which
has a subsidiary a company declared not to be an electric utility company
pursuant to Section 2(a)(3).4

----------
2    Mesquite Power, LLC, 94 FERC P. 62,235 (2001) (determining Mesquite Power
     to be an EWG). SER owns Mesquite Power through its wholly-owned subsidiary
     SEP II, the sole member in Mesquite Power.

3    See Application for Expedited Consideration of Intracorporate Transfer
     filed in FERC Docket No. EC03-88-000 on May 12, 2003.

4    Section 2(a)(3) also provides that the Commission may as a condition to an
     order under Section 2(a)(3)(A) "require application to be made periodically
     for a renewal of such order, and may require the filing of such periodic or
     special reports regarding the business of the company as the Commission may
     find necessary or appropriate to insure that such company continues to be
     entitled to such exemption during the period for which such order is
     effective." SER expects to need an exemption under Section 2(a)(3)(A) for a
     brief period not to exceed one month. It therefore believes that any such
     requirements would serve no purpose in this case.


                                       3

     SER clearly meets the requirements set forth in Section 2(a)(3)(A). First,
it is engaged in one or more businesses other than the business of an electric
utility company, as defined in Section 2(a)(3) of the Act. Specifically, SER
engages in energy project development, ownership of power producers that are not
public utility companies under the Act, extensive marketing of electric power,
and purchases and sales of other energy-related products. None of these
activities would subject an entity to regulation as either an electric utility
company or a holding company under the Act. The Commission has taken the
position in a series of no-action letters that the paper assets owned by power
marketers do not constitute electric utility facilities and that power trading
does not by itself make an entity an electric utility company under the Act.5 In
addition, Commission Rule 58(b)(1)(v) under the Act treats power marketing as a
non-utility energy-related business. Other than the Mesquite Project upon
commencement of commercial operations, SER neither owns, operates nor will own
or operate any facilities that would cause it to become an electric utility
company.6 Therefore, while SER engages in an extensive array of energy-related
activities, none of these activities cause it to become an electric utility
company. It thus is primarily engaged in one or more businesses other than that
of an electric utility company.

     Secondly, SER will sell a small amount of electricity using the Mesquite
Project during the period that it will operate the Mesquite Project. SER expects
that during this period its revenues from sales of electricity generated by the
Mesquite Project will be approximately $10 million. On the other hand, SER had
approximately $322 million in operating revenues in 2002 and expects to have
operating revenues for 2003 of approximately $500 million. Its expected power
sales thus will be approximately 3.1 percent of its known 2002 operating
revenues and approximately 2 percent of its expected 2003 operating revenues.
The Commission has not established a test for what constitutes a small amount of

----------
5    See, e.g., Enron Power Marketing, Inc., SEC No-Action Letter (Jan. 5,
     1994); EML Power LLC, SEC No-Action Letter (Nov. 12, 1999).

6    While the Mesquite Project is an eligible facility, as defined in Section
     32(a)(2) of the Act, and while a number of the activities that SER engages
     in may under FERC precedent qualify as allowable EWG incidental activities,
     it is SER's understanding, based on FERC precedent and discussions with
     FERC staff that FERC would be unlikely to grant EWG status to SER at this
     time because its energy-related activities qualitatively and quantitatively
     go beyond the scope of allowable incidental activities, such as power
     marketing operations, purchase and resale of transmission capacity and
     financial instruments and certain gas sales, in each case, unrelated to the
     eligible facilities in which it owns an interest. For this reason, Section
     32(i) of the Act does not apply to the Commission action requested in this
     Application.

                                       4


electricity in this context, but this amount is consistent with existing
Commission precedent.7

     Finally, it should be noted that SER's exemption would be of limited
duration. Once the necessary FERC approval has been obtained, and the Mesquite
Project is transferred to Mesquite Power, SER will no longer need to retain the
exemption it seeks in this Application. The Commission has indicated that the
limited duration of an exemption can be a consideration that supports the
granting of an exemption under Section 2(a)(3)(A).8

     For all these reasons, SER qualifies for an exemption under Section
2(a)(3)(A) of the Act.

Item 4. Regulatory Approval
        -------------------

     SER requires no other regulatory approvals that are relevant to the subject
matter of this Application.

Item 5. Procedure
        ---------

     SER respectfully requests that the Commission issue and publish not later
than June 20, 2003 the requisite notice under Rule 23 with respect to the filing
of this Application, such notice to specify a date not later than July 8, 2003
by which comments may be entered and a date not later than August 8, 2003 as a
date after which an order of the Commission granting this Application may be
entered by the Commission.

     SER hereby (i) waives a recommended decision by a hearing officer, (ii)
waives a recommended decision by any other responsible officer or the
Commission, (iii) consents that the Division of Investment Management may assist
in the preparation of the Commission's decision, and (iv) waives a 30-day
waiting period between the issuance of the Commission's order and the date on
which it is to become effective.
