hereby notifies the Commission, pursuant to Section 33(a) of the Act and Rule 57

thereunder, that during the reporting period, COPESA was a foreign utility

company within the meaning of Section 33(a) of the Act.

          The name and business address for COPESA is as follows:

             COPESA
             Avenida Federico Boyd
             E.D.F. Scotia Plaza
             PISO VI Panama City, Panama

          Listed below is a description of the COPESA facility:

          COPESA owns an approximately 42 MW diesel-fired combustion turbine

facility located in Panama City, Panama.  The project sells electricity to

distribution companies and large industrial users in Panama.

     b.   Name of each system company that holds an interest in such EWG or

foreign utility company; and description of the interest held.

          The ownership of COPESA is as follows:

          A.   Nations International Ltd., a wholly-owned subsidiary of Nations

Energy, holds a 40% equity interest in COPESA.

          B.   Electric Machinery Enterprises, a Florida company, holds a 21.67%

equity interest in COPESA.

          C.   Proquim, a Panama company, owns a 22.67% equity interest in
COPESA.

          D.   Martino, S.A., a Panama corporation, holds an 11.66% equity

interest in COPESA.

          E.   Ingenieria R-M, S.A., a Panama corporation, holds a 3% equity

interest in COPESA.

          F.   The remaining 1.0% equity interest in COPESA is held by certain

Panamanian individuals.

     c.   Type and amount of capital invested, directly or indirectly, by the

holding company claiming exemption; any direct or indirect guarantee of the

security of the EWG or foreign utility company by the holding company claiming

exemption; and any debt or other financial obligation for which there is

recourse, directly or indirectly, to the holding company claiming exemption or

another system company, other than the EWG or foreign utility company.

          During 2002, no additional amounts were invested by Nations

International Ltd. as additional equity in COPESA.  Project debt in COPESA is

non-recourse.

     d.   Capitalization and earnings of the EWG or foreign utility company

during the reporting period.

          The financial information for COPESA for the year ended December 31,

2002 has not been made available to UniSource Energy at the time of this filing.

UniSource Energy has been advised by adminstrative personnel of COPESA that the

2002 financial statements have not yet been completed by COPESA's auditors

because the auditors were delayed in beginning their reveiw of 2002 financial

information as the Panama internal revenue service was conducting a tax audit of

COPESA for prior years, and that audit was only recently completed.  Based on

information furnished by COPESA personnel, UniSource Energy expects that the

financial information for 2002 will be available shortly.  Upon receipt of that

information, this filing will be supplemented to include the 2002 financial data

for COPESA.

     e.   Identify any service, sales or construction contract(s) between the

EWG or foreign utility company and a system company, and describe the services

to be rendered or goods sold and fees or revenues under such agreement(s).

          Inapplicable.

                                   ---------

     Consolidating statements of income of the claimants and their subsidiary

companies for the last calendar year, together with the consolidating balance

sheets of claimants and their subsidiary companies as of the close of such

     This statement is being filed by TEP to claim exemption in the event that

San Carlos Resources Inc. is an "electric utility company" under the Act.

However, the filing of this statement is not an acknowledgment by TEP that San

Carlos Resources Inc. is an "electric utility company."

     The above-named claimants have caused this statement to be duly executed on

their behalf by its authorized officer on this 28th day of February, 2003.

UniSource Energy and TEP use the following methods to report investments in their subsidiaries or other companies:

 - Consolidation:  When we own a majority of the voting stock of a subsidiary and we have control over the subsidiary,
   we combine the accounts of the subsidiary with our accounts.  We eliminate intercompany balances and transactions
   when we combine these accounts.

 - The Equity Method: We use the equity method to report corporate joint ventures, partnerships, and affiliated
   companies when we hold a 20% to 50% voting interest or we have the ability to exercise  significant influence
   over the operating and financial policies of the investee company.  Under the equity method, we report:

   - Our interest in the equity of an entity as an investment on our balance sheet; and
   - Our percentage share of the net income (loss) from the entity as "other income" in our income statements.
     For investments where we are committed to providing all of the financing, we recognize 100% of the losses.

 - The Cost Method: When we do not own enough shares to exercise significant influence over an investee company, we
   use the cost method to report these investments.  Typically the cost method is used for investments of less than
   20% of the voting interest in an investee company.  Under the cost method we report:

   - Our interest in the equity of an entity as an investment on our balance sheet; and
   - Income based on dividend distributions from the investee company; and
   - Loss when impairment of the value of the investment becomes evident.
