4.2 - Tariff adjustment

4.2.1- ESCELSA

On August 6, 2004, ANEEL published Approval Resolution 191/04, which fixed
ESCELSA tariffs, effective from August 7, 2004 to August 6, 2005, with an
average adjustment of 4.96%.

This adjustment index is reduced by 5.11% due to a remuneration basis arbitrated
by ANEEL, lower than that used as provisory in the August 2001 review. With this
new basis, the adjustment at the time, which was 19.89%, reduced to 17.80%.

This percentage reduction was applied to the sales from August 7, 2001 to August
6, 2004, resulting in a difference of R$ 56,720, equivalent to the 5.11%
deduction in the tariff adjustment of August 6, 2004.

In compliance with the dispositions of article 8, the adjustment amount must be
returned to ESCELSA consumers. Item 60 of the Technical Note 135/2004-SRE/ANEEL
specified that this return will be made within 12 months. Accordingly, the 5.11%
reduction will be effective until the next readjustment scheduled for August 7,
2005.

4.2.2 - ENERSUL

On April 8, 2004, ANEEL published Approval Resolution 73/04 altering the
periodical tariff adjustment of the subsidiary ENERSUL in April 2003, and
changing the adjustment percentage from 42.26% to 43.59%, and the X Factor from
2.35% to 1.35%.

In this Resolution, the phasing of the tariff adjustment was maintained, as had
been defined in 2003 by that Regulatory Agency, in order to follow the principle
of moderate tariffs and the economic/financial equilibrium of the ENERSUL
Agreement for Distribution Concession, as follows:

a)   In the first year, the tariffs for supply of electric energy were adjusted
     based on the Tariff Adjustment Index (IRT) of 32.47%; and
b)   In the annual tariff adjustments to be approved for the years 2004 to 2007,
     the difference between IRT and the tariff adjustment (RT) will be added to
     Portion B.

Considering item "b" above, ENERSUL provisioned during this quarter the income
and related taxes amounting to R$ 14,786, and started recoveries via tariff in
April 2004, recovering in the quarter R$ 7,362. The balances of these assets are
recorded in "Provision for tariff adjustment", the movement on which during the
period was as follows:

5. GENERAL ELECTRIC ENERGY SECTOR AGREEMENT

The General Electric Energy Sector Agreement, to which the Company adhered to on
December 20, 2001, established conditions for settling contractual and
administrative disputes and eliminating the possibility of judicial or
extrajudicial suits over issues arising from the electric energy rationing
period. The main points of the Agreement are as follows:

o    Declaration of desistence/renunciation;
o    Purchase agreement for net contractual surpluses;
o    Agreement for reimbursement of free energy;
o    Addendums to the initial contracts; and
o    Energy Development Account (CDE).

Based on Provisional Measure 14/01, converted into Law 10438/02, and related
legislation, the Company calculated the amount of the extraordinary tariff
recomposition applicable to all electric energy distribution companies, for the
purpose of neutralizing the margin losses resulting from the Emergency Program
for Reducing Electric Energy Consumption (PERCEE), in effect from June 2001 to
February 2002.

At the same time, in common with the other electric energy distribution
utilities, the Company calculated the monthly variations of costs not managed by
the companies (Portion A) and listed all the additional energy purchase costs in
the MAE (free energy) ambit to be repassed to the generators.

ANEEL Resolutions 480 and 481 (concerning margin losses), 482 (concerning
Portion A costs) and 483 (concerning free energy), all dated August 29, 2002,
approved the amounts of the revenue recomposition, the extraordinary electric
energy tariffs of which were as follows:

||   2.9% for residential customers (except low income users), rural users and
     public lighting;
o    7.9% for all other customers.

ANEEL Resolution 1/04 fixed new periods for application of the Extraordinary
Tariff Recomposition (RTE) (losses and free energy), modifying the tariff
recovery period from 70 to 69 months (82 to 73 months - ENERSUL), starting as
from December 2001.

Studies undertaken by management indicate that these assets will be fully
collected over the maximum period established, and therefore no provision for
losses was recorded.

5.1 - Recovery of electric energy supply losses

These losses, which are part of RTE, were as follows during the period:

5.2 - Free energy

Free energy refers to electric energy that was generated but is not part of the
initial or any equivalent agreements.

According to the Free Energy Reimbursement Agreement, electric energy generation
companies, supported by article 2 of Law 10438, paid market prices for the free
energy allocated to them by MAE (MAE prices) during the PERCEE period according
to pre-established rules.

The distribution utilities, benefited by the Extraordinary Tariff Recomposition
(RTE), will reimburse the generating utilities for the difference between the
MAE price and R$ 49.26 per MWh.

The amounts of this reimbursement were calculated according to MAE accounting
and shared among the distribution companies, proportionally to individual
consumption of energy in the National Interconnected Electricity System. The
amount of this electric energy is being reimbursed to the generating companies,
in conjunction with the RTE over 69 months (73 months for Enersul), composed as
follows:

The amounts were recorded in the Consumers and concessionaires account, in
current assets and long-term receivables, with a contra entry to Unbilled
revenue. An obligation in the same amount was recorded in the Energy suppliers
account in current and long-term liabilities, with a corresponding charge to
results in the Energy purchased for resale - short-term account.

5.3 - Variation in the composition of Portion A costs

In order to determine the concessionaires' tariffs practiced, the electric
energy distribution concession agreements establish amounts for each item of
those exogenous costs that are part of the operating expenses known as the
variable Portion A of the IRT formula, as follows:

o    Tariff for the transfer of the energy potential from Itaipu Binacional;
o    Tariff for the transport of the electric energy from Itaipu Binacional;
o    Quota for the Fuel Consumption Account (CCC);
o    Costs for transmission infrastructure usage on the basic grid;

     (*)  As from December 2002 there was an increase in the PIS rate from 0.65%
          to 1.65% and, as from February 2004, in the COFINS rate from 3% to
          7.6%. This increase was followed by the non-cumulativity principle of
          these taxes. ANEEL did not recognize the increase of these rates on
          the electric energy tariff, the indirect costs of which the Company
          has been recording as PIS/COFINS expenses. Based on Official Letter
          1482/2004 - SFF/SRE/ANEEL of September 6, 2004, the Company set up
          regulatory asset of the amount calculated between the rates and the
          previous systems with the current rates and the non-cumulativity
          principle since the dates of the increases.

According to Interministerial Ordinance 116/03, the CVA balance will be included
in the electric energy supply tariffs in the 24 months subsequent to the annual
tariff adjustment that will occur between April 8, 2004 and April 7, 2005. The
postponement includes, in the case of ESCELSA, the balance for the period from
August 2002 to July 2003 and, for ENERSUL, from April 2002 to March 2003, plus
an amount to be calculated in the 12 months subsequent to the adjustments from
August 2003 and April 2003, respectively.

5.4 -Emergency Capacity Charge

Established by Provisional Measure 14/2001, converted into Law 10438/2002, the
objective of this charge is to cover the costs necessary for contracting the
generation capacity or electric energy potential by Comercializadora Brasileira
de Energia Emergencial - CBEE. The electric energy distribution concessionaires
are responsible for the billing of this charge which reaches all consumer
classes, except the residential classified as low income, based on the
individual consumption.

The collection of this charge, approximately R$ 0.0085/kWh, is fully repassed to
CBEE, net of the taxes generated.

5.5 -SELIC remuneration

In accordance with current legislation, the RTE, Free Energy and CVA balances
are remunerated based on the SELIC interest rate, and the amount of R$ 35,213 is
recognized in results for the period ended September 30, 2004 (R$ 37,198 at
September 30, 2003) in the parent company and R$ 51,267 at September 30, 2004
(R$ 75,852 at September 30, 2003) in the consolidated.


6.   LOW INCOME CONSUMERS

Law 10438/02 established the guidelines for classifying the low income
residential sub-category, which was defined as a consumption unit with monthly
consumption of less than 80 kWh. Decree 4336/02 expanded the rules to include
units with monthly consumption between 80 and 220 kWh.

04.01 - Notes to the Quarterly Information
(All amounts in thousands of reais unless otherwise indicated)
- -------------------------------------------------------------------------------

As a result of the new classification, there was a loss on revenues amounting to
R$ 18,172 at September 30, 2004 (R$ 15,359 at September 30, 2003) in the parent
company and R$ 27,042 (R$ 21,929 at September 30, 2003) in the consolidated, net
of the Added Value Tax on Sales, Interstate and Intercity Transport Services and
Communications (ICMS).

As a result of Normative Act 03/03, published in the Diario Oficial do Estado do
Espirito Santo (Official Gazette) on November 24, 2003, issued by the Treasury
Secretariat of the State of Espirito Santo, which declares that the portion of
the subvention by the Federal Government exceeding the exempt residential
consumption based on the ICMS state legislation (50 KWh/month) is subject to
ICMS tax, management, prudently, set up a provision for a probable tax liability
of R$ 10,351 (consolidated - R$ 13,840), charged against taxes in operating
expenses.

Based on ICMS Agreement 78/04, published in the Official Gazette of September
30, 2004, the states of Espirito Santo and Mato Grosso do Sul, among others,
were authorized to dispense with the collection of ICMS related to the
subvention installments of the energy supply to low income residential
consumers, from May 1, 2002 to February 29, 2004. Accordingly, management
released the provision for tax liability of R$ 10,351 (R$ 14,941 in
consolidated).

8. DEFERRED INCOME TAX AND SOCIAL CONTRIBUTION

The tax credits listed below relative to income tax and social contribution
losses and other amounts that constitute temporary differences, to be used for
reduction of future taxation, were recorded based on the Company's profitability
history and expected taxable income for the coming years, considering a maximum
period of ten years.

As a result of the rules laid down by CVM Instruction 371/02, the Company did
not record new credits, as from July 1, 2002, in the amounts of R$ 108,705 in
the parent company and R$ 143,689 in the consolidated at September 30, 2004.

Based on these assumptions, the amounts of the tax assets to be appropriated
were determined as follows:

Based on SRF COSIT Opinion 26/02 and decisions of the 1st, 2nd and 6th Federal
Revenue Regional Superintendencies (SRF), the subsidiary Enersul claimed the
right at the administrative level to defer taxes on RTE (recovery of rationing
losses and free energy), as well as on the energy spot market (MAE).

Through Notification 5/04, the Company was informed of Decision 3.103/03 of the
Federal Tax Department's Regional Office in Campo Grande - MS, approving the
request for deferral of the above mentioned revenues in respect of the related
federal taxes.

In view of this fact, the Enersul tax credits, originally written-off in 2001,
were reconstituted and the following deferred tax liabilities recognized, which
are being realized.

9.1 - Other receivables and payables

These transactions refer basically to the transfer of costs of related
companies, including administrative and technical cooperation activities.

9.2 - Energy purchased for resale

ENERTRADE

On December 23, 2002, ESCELSA and its indirect subsidiary ENERSUL signed with
ENERTRADE - Comercializadora de Energia S.A. an agreement for the purchase and
sale of electric energy, effective from January 1, 2003 to December 31, 2012,
covering, for the parent company, an average of 11.45 MW in 2003 and 52 MW as
from 2004, and for ENERSUL an average of 35 MW at prices of R$ 85.67/MWh
(ESCELSA) and R$ 80.21/MWh (ENERSUL), altered on February 19 and March 20, 2003,
to R$ 83.73/MWh and R$ 79.77/MWh, respectively.

These prices were established according to the rules on the Normative Value
(VN), included in ANEEL Resolution 248/2002, applicable at the time the
agreements were entered into and submitted for registration with ANEEL on
December 23, 2002.

During the ESCELSA tariff adjustment process, the Company became aware that
ANEEL did not accept the agreement amount, fixing the amount of R$ 74.79/MWh
(base date: December 2002), taking into consideration the Technical Notes issued
by ANEEL.

During the tariff adjustment process, ENERSUL requested the transfer to the
tariff of the agreement amount restated through April 2003, that is, R$
104.74/MWh, based on current legislation. However, ANEEL recognized only R$
84.33/MWh, the average price in the Southeast region auctions for six-year
agreements.

On April 25, 2003 and August 29, 2003, ENERSUL and ESCELSA, respectively, filed
administrative appeals at ANEEL defending the full application of the
contractual amounts, for recognition in the tariff, using the following
arguments:

a) ENERSUL: (i) absence of a normative basis for recognizing only R$ 84.33/MWh;
(ii) the cost of energy purchased limited by the VN methodology must be repassed
to the electric energy tariffs, as determined by the 5th and 6th subclauses, of
clause 7 of the Concession Agreement.

b) ESCELSA: (i) the non-existence of market price references for long-term
agreements more than the marginal cost of expansion; (ii) the equivalence of
contracted price with VN, which is lower than the marginal cost of expansion,
this aligned with the moderate tariffs prescribed in the Concession Agreement;
and (iii) the long-term agreement confers and assures stable and foreseeable
prices to final consumers.

Through Official Letters 1769/03 and 1779/03-SFF/ANEEL, of October 29, 2003,
ANEEL did not approve the ENERSUL and ESCELSA agreements, and confirmed the
previous understanding to recognize R$ 79.48/MWh at the base date March 2003 and
R$ 74.79/MWh at the base date December 2002, for each of the concessionaires, in
this order.

ENERTRADE submitted the issue to the Judiciary Power, obtaining a favorable
decision in Bill of Review 2004.01.00.007.806-5/DF, which determined the
overestimation of the effects of Letters 1769/03 and 1779/03-SFF/ANEEL and
recognized the approval of the agreements for all legal purposes, until a
definite pronouncement of the Judiciary Power. This decision was communicated
through Letter 166/ENERTRADE dated March 15, 2004.

The subsidiary ENERSUL through Letter CT-PR-5/04, reported such decision to
ANEEL, with reiteration of the request for recognition of the amounts of R$
104.69/MWh in April 2003 and R$ 109.52/MWh in April 2004, in the tariff
adjustment process in course, which is still pending reply from the Agency.

On May 21, 2004, in the Periodical Tariff Review process, ESCELSA, through
letter CT-PR -18/04, reiterated the request to repass to the tariffs the
contract amounts, signed on December 23, 2002 with ENERTRADE, based on the
decision of the Judiciary Power which determined that ANEEL approve the
mentioned contract.

Up to third quarter 2004, the price differences in question reached the amount
of R$ 7,426 thousand for ESCELSA and R$ 5,652 thousand for ENERSUL, recorded in
operating expenses.

Administrative decisions on the appeals are awaited, and judicial solutions are
available if there are unfavorable decisions.

04.01 - Notes to the Quarterly Information
(All amounts in thousands of reais unless otherwise indicated)
- -------------------------------------------------------------------------------


14.1 - The issuance of bonds abroad refers to the funding obtained through
Senior Notes, in a total equivalent to US$ 430,958 thousand, falling due in a
single installment in 2007, with interest of 10% p.a., payable on a semiannual
basis, on January 15 and July 15 of each year. On May 21, 1998, these Notes were
registered with the Securities and Exchange Commission (SEC), in the United
States of America, in accordance with the Securities Act of 1933.

The indirect controlling shareholder EDP - Electricidade de Portugal S.A. made a
public offer for the acquisition and request of waiver related to the Notes,
having acquired the principal of US$ 205,796 thousand, with settlement on
December 23, 2002. Before making such offer, EDP held a total of US$ 151,575
thousand in Notes, representing, approximately, 35% of the total issue. Thus EDP
became the holder of a total of US$ 357,371 thousand in Notes, representing
approximately 83% of the total issue, and the main covenants relating to these
Senior Notes were removed. ESCELSA eliminated all obligations inherent to this
issuance.

14.2) ESCELSA and ENERSUL loans from ELETROBRAS, BNDES and Banco do Brasil - FCO
are guaranteed by their receivables. The ENERSUL loans from the Secretariat of
the National Treasury (STN) are guaranteed by debit in an account, of
receivables, by the government of the State of Mato Grosso do Sul and part by
cash deposit. The other loans are guaranteed by promissory notes. The MAGISTRA
loan payable to BNDES is guaranteed by ENERSUL shares in escrow.

14.3) The breakdown of loans and financing by currency is as follows:

20. PENSION PLAN

The Company is the sponsor of FUNDACAO ESCELSA DE SEGURIDADE SOCIAL - ESCELSOS,
a nonprofit organization, the main purpose of which is to complement the
benefits granted by the official social security to the Company's employees,
through two benefit plans: a Defined Benefit Plan (Plan I) and a Defined
Contribution Plan (Plan II).

The mathematical reserves of these plans are calculated actuarially according to
the capitalization method, and reviewed annually.

The table below shows the number of participants in each plan on September 30,
2004:

04.01 - Notes to the Quarterly Information
(All amounts in thousands of reais unless otherwise indicated)
- -------------------------------------------------------------------------------



As sponsor, ESCELSA contributes with a monthly amount proportional to the
contribution of the participants in the ESCELSOS Foundation, in accordance with
that established in each plan, and the maximum percentage of the Company's
contribution, considering the two plans, is limited to 7% of the total payroll.
Up to the third quarter of 2004, ESCELSA contributed R$ 2,217 (R$ 1,955 in
2003).

As established in CVM Deliberation 371/00, as from January 1, 2002, publicly
listed companies are required to record liabilities related to post-employment
benefits, based on rules set forth by NPC (Accounts Procedure Rule)
Pronouncement 26 issued by the Institute of Independent Auditors of Brazil
(IBRACON). To meet this requirement, ESCELSA commissioned independent actuaries
to evaluate such benefits, based on the Projected Unit Credit Method.

Taking into consideration article 84 of the Deliberation, the present value of
the actuarial liabilities (health care, retirement incentive and life insurance)
of ESCELSA not covered at December 31, 2002 was recalculated. The balance
activity up to the third quarter of 2004 is as follows:

                                                             PARENT COMPANY

                                                          ------------------


Present value of actuarial obligations
   not covered                                                     (53,575)
Net unrecognized losses                                              19,751
                                                          ------------------
Liabilities recognized on December 31, 2003                        (33,824)
Realized during the period                                            1,428
                                                          ------------------
Liabilities recognized on September 30, 2004                       (32,396)
Current                                                               2,143
                                                          ------------------
Long-term                                                            30,253
                                                          ==================


The net amount of unrecognized losses corresponds to the net amount of the
actuarial losses exceeding 10% of the present value of the actuarial obligations
at December 31, 2003, which will be appropriated annually, during the period
corresponding to the average remaining work period estimated for the employees
who adhered to the Plan.

The actuarial assessments of ESCELSA and ENERSUL showed also that in the Plans
the fair value of assets exceeds the present value of the fully or partially
covered actuarial obligations, which, at December 31, 2003, amounted to R$
28,079 (consolidated R$ 44,051).

However, the Companies' management, on a conservative basis, decided not to
record these assets.

The fair value of assets used to calculate the result of the actuarial
evaluation of ENERSUL does not include the receivables from the sponsor arising
from the debt confession amounting to R$ 19,250 (12/31/2002). Considering this
right of the Foundation in the calculation of the asset not recognized in the
balance at December 31, 2002, the same would increase to R$ 35,222 (R$ 64,301 in
consolidated).


21. INSURANCE (Unaudited)

The following is a breakdown by risk type and by validity period of the main
insurance policies:

RISKS                   VALIDITY                 INSURED AMOUNT   PREMIUM AMOUNT
- ----------------------- ------------------------ ---------------  --------------

Third-party liability   06/24/2004 to 06/23/2005         4,770              76

Specific equipment

22. FINANCIAL INSTRUMENTS

The Company's business comprises the distribution and sale of electric energy to
customers within its concession area - the state of Espirito Santo - and,
therefore, significant financial instruments are related to the following
transactions:

|X|  Balances of long-term accounts receivable and accounts payable are related
     to the extraordinary tariff recomposition and, therefore, are not subject
     to adjustments to market values.

|X|  Investments in short-term mutual funds and/or fixed income investments are
     recorded at approximate market values as they are adjusted for accrued
     interest on a pro-rata basis, and for a provision for losses when
     applicable.

|X|  Equity interests in other companies are in most cases through shares that
     are not publicly traded.

|X|  Loans and financing of the Company are mainly long term, since most of them
     are from specific funding sources.

22.1 Foreign exchange and interest rate risks

The book values of the main financial instruments in foreign currency are as
follows:

04.01 - Notes to the Quarterly Information
(All amounts in thousands of reais unless otherwise indicated)
- -------------------------------------------------------------------------------


As the market rate (or opportunity cost of capital) is defined by these
government entities, taking into consideration the risk premium relative to the
sector's activities and the fact that there are no other financing sources or
market options and/or means to estimate the market value thereof in light of the
Company's business and sector peculiarities, the market value for the portion
comprised of local loans approximates book value, as do other financial assets
and liabilities.

As mentioned in Note 14, foreign currency financing obtained (in U.S. dollars),
and the indebtedness and earnings were significantly impacted by the foreign
exchange risk.

Such risk may cause the Company to incur losses due to foreign exchange
fluctuations, which may increase the liabilities denominated in foreign
currency.

The net exposure to foreign currency risks of the parent company's financial
instruments is as follows:

                                   BOOK VALUE               MARKET VALUE

U.S. dollar assets            190,566       201,974      214,320       221,038

                          ============  ============  ============  ============


The method used to determine the fair value of the Senior Notes obligation was
the average market price, as of September 30, 2004, of Senior Note transactions
(Source: Sherman & Sterling), in New York, USA, and, for the U.S. dollar assets,
the contract market price at the end of the period was used, which is equivalent
to book value.

In addition, the Company had derivative contracts aimed at reducing the above
mentioned net exposure, which resulted in monetary variations being recorded in
the financial statements for realized and unrealized losses of R$ 5,502, as
follows:

In consolidated, the loans and financing contracted by companies of the ESCELSA
System were raised based on rates and charges usually practiced in the local and
foreign markets for investment funding in the electric energy sector in their
concession areas.

The subsidiary MAGISTRA consolidates the foreign currency (US$) financial
liabilities of its subsidiaries ENERSUL and CESA. In order to reduce foreign
exchange and interest rate risk, swap instruments were used to hedge a portion
of these liabilities, with changes of indices, as described in Note 14.

These swap indices are CDI, plus interest between 0.95% p.a. and 3.35% p.a.

Considering the appreciation of the real against the U.S. dollar, these hedge
transactions yielded losses of R$ 7,587, recognized in the financial statements,
in monetary variations.

At September 30, 2004, the position of this debt was as follows:

                                                         AMOUNT

Loans and financing                   69,899              77,486      7,587


In the consolidated position, foreign currency debt totals R$ 74,196, the terms
and conditions of which constitute a natural hedge, thus reducing the foreign
exchange and interest rate risks to a minimum.

For the remaining contracts, given the peculiar characteristics of these
transactions and the impossibility of determining a market value for this type
of financial instrument, management estimates that the market or realizable
values of these instruments are equal or approximate to their book values.

To determine this estimate, management considered the evidences of risks
inherent to the business, the strategy and the measures taken to manage the debt
service.

22.2 Credit risk

There is a possibility that the Company will incur losses due to default of its
customers.

To reduce this risk, the Company has the right to interrupt the supply of
electric energy if a customer fails to make payment within the parameters and
periods defined by legislation and specific regulations. An allowance for
doubtful accounts is set up in an amount considered sufficient by management to
cover possible accounts receivable risks.


23. PROGRAMA NACIONAL DE UNIVERSALIZACAO

Through Decree 4873/03 the Federal government created the Programa Nacional de
Universalizacao - Luz para Todos (National Program of Universalization -
Electricity for All) in order to provide access to public electric energy
services for the entire Brazilian rural population up to 2008.

The Company is defined as an executing agent of the Program, that is, it is
compulsorily responsible for its execution and will have a 75% financing on the
applicable amount.

Within the regulation established by the Federal Government, through the
Ministry of Mines and Energy (MME), a commitment between the Ministry of Mines
and Energy, the state government and ESCELSA was signed on May 19, 2004, with
the intervention of ANEEL and ELETROBRAS, to serve 10,694 consumers in the
Company's concession area, from July 2004 to December 2005. The total amount of
R$ 67,647 is estimated for application, the amounts and resources of which are
distributed as follows: (i) Executing agent - R$ 31,915; (ii) RGR- ELETROBRAS
financing - R$ 30,968; (iii) CDE (lost fund) - R$ 4,764.

On May 21, 2004, a financing agreement with ELETROBRAS was signed, in the global
amount of R$ 35,732, of which R$ 30,968 for resources arising from RGR
(financing) and R$ 4,764 for resources arising from CDE (lost fund).

24. NEW MODEL OF THE ELECTRIC SECTOR

The Federal Government, through the Ministry of Mines and Energy (MME),
presented an outline of its project for the national electric sector reform,
especially as it relates to the institutional model, culminating with the issue
of Provisional Measures 144 and 145/03, converted into Laws 10848 and 10847/04,
respectively.

The relevant points are:

o    Transfer of responsibilities of ANEEL to MME.
o    Creation of the Energy Research Company (EPE), of the Committee of Electric
     Sector Monitoring (CMSE) and the Chamber of Electric Energy
     Commercialization (CCEE), organs which will promote the planning and
     monitoring of the generation and transmission expansion, in addition to
     market management.
o    Definition of rules for electric energy sales, with emphasis on: (i) offer
     expansion (new projects for energy production) through auctions; (ii) free
     (ACL) and regulated (ACR) contracts; (iii) distribution activities focused
     on line service and networks, and energy sales to captive customers; (iv)
     restrictions on contracts between related parties; and (v) new rules for
     free consumer classes.

On July 30, 2004, the Federal Government published Decree 5163, which (i)
regulates the sale of electric energy in the Regulated and Free Contracting
Environments and (ii) provides for the process for granting concession and
authorization to electric energy generation. The main dispositions are:

o    General rules on electric energy sale;

o    Sale of electric energy in the Regulated Contracting Environment (including
     the rules about information and declarations of electric energy needs,
     auctions for purchase of electric energy, electric energy sale and purchase
     agreements and repass of tariffs to the consumers);

o    Sale of electric energy in the Free Contracting Environment;

o    Recording and settlement of differences in the short-term market; and

o    Concession grantings.

                                       47

Due to this regulation, all extent aspects that its effects will produce should
be verified, as well as the complexities that will impact on Company's
operations, in order to evaluate the risks and opportunities that could impact
its business.


25 - CORPORATE RESTRUCTURING

On April 20 and 21, 2004, ESCELSA and its subsidiary ENERSUL published a
Significant Event Notice concerning the request for prior approval of ANEEL in
order to carry out a corporate restructuring, under the terms of current
legislation.

The notice was as follows:

                            SIGNIFICANT EVENT NOTICE
The management of EDP BRASIL S.A. ("EDP Brasil"), BANDEIRANTE ENERGIA S.A.
("Bandeirante"), IVEN S.A. ("Iven"), ESPIRITO SANTO CENTRAIS ELETRICAS S.A. -
ESCELSA ("Escelsa") and EMPRESA ENERGETICA DE MATO GROSSO DO SUL S.A. - ENERSUL
("Enersul") (EDP Brasil, Bandeirante, Iven, Escelsa and Enersul, collectively
referred to as the "Companies"), under the terms and for CVM Instruction 358/02
purposes, publicly inform that, on this date, they filed with the Brazilian
Electricity Regulatory Agency ("ANEEL") a request for prior approval of the
corporate reorganization (the "Reorganization"), the main objective of which is
to simplify the Companies' corporate structure, obtain synergies and
consolidate, exclusively in EDP Brasil, the liquidity and dispersion of the
securities issued by the Companies. EDP Brasil intends to, in the future, adhere
to the segment of the New Market of the Sao Paulo Stock Exchange. The
Reorganization is part of an ongoing process aiming at the self-sustainable
growth of the EDP companies in Brazil. The Reorganization does not change the
Companies' indirect control, currently held by the EDP Group.

The Reorganization will include the stages described below, which, subject to
the prior approval of ANEEL, are expected to occur on the same date, but in
sequence and in the following order:

        (i)    merger into Enersul of the investment and goodwill recorded in
               its direct parent company;

        (ii)   merger of Iven into Escelsa;

        (iii)  merger into Escelsa of the Enersul shares not held by the merging
               company; and

                                       48

        (iv)   merger into EDP Brasil of the Escelsa and Bandeirante shares not
               held by the merging company.

EDP Brasil has already started to prepare the necessary documentation for
registration as an open capital company and be able to trade its shares in the
New Market segment. According to applicable legislation, specialized companies
will be contracted to calculate the Companies' economical values, which will be
the basis to determine the exchange ratio for substitution of the shares of the
non-controlling shareholders, as well as to prepare the appraisal reports of the
accounting net equities and the market values of the Companies.

Subject to the prior approval of ANEEL, the Reorganization is expected to be
implemented and concluded in the second six-month period of 2004, when a
significant event notice will be published for CVM Instruction 319/99 purposes.

The Regulatory Agency had not manifested itself on the matter by the end of this
quarter.

Energy sold (*)

Energy sales up to the 3rd quarter of 2004 totaled 4,177,167 MWh, while sales
during the same period in the previous year reached 4,412,902 MWh, representing
a decrease of 5.3%.

The decrease verified in the residential sector was due to reduced consumption
as the result of climatic conditions in the concession area where average
temperatures were milder than normal, and the decrease in the rural sector was
due to heavy rains that reduced irrigation activities.

In the industrial sector, the decrease was due to customers Belgo Mineira and
CST leaving to seek energy in the open market. Excluding the consumption of
these customers in 2003 and 2004, the market grew 3.0% in the industrial sector
and the global market variation (retail + wholesale) is 0.1%. It should be noted
that a drop in consumption reduces revenues from supply and the expenses related
to purchasing energy, being offset by an increase in revenues from use of the
distribution system.

ECONOMIC-FINANCIAL ASPECTS

In the quarter, non-recurring events which had impact on the financial
statements were recorded as follows:

1. Tariff adjustment - effects of the tariff return defined in the 3rd review of
August 2004.

On August 6, 2004, ANEEL published Approval Resolution 191/2004, which fixed
ESCELSA tariffs, effective from August 7, 2004 to August 6, 2005, with an
average adjustment of 4.96%.

This adjustment index, already reduced by 5.11%, considers ANEEL arbitration of
a remuneration basis for 2001, in the amount of R$ 796 million, lower than that
used as provisory, in the amount of R$ 980 million, at the time of the 2nd
tariff adjustment in August 2001. With this new basis, the adjustment at the
time, which was 19.89%, changed to 17.80%.

The difference between these adjustment percentages was applied to the electric
energy sold during the period between the 2nd and 3rd adjustments, amounting to
R$ 46,950 thousand which, restated by IGP-M, totaled R$ 56,720 thousand.

This total represented a discount of 5.11% in the tariff readjustment, which
started to be applied as from August 7, 2004 until August 6, 2005. In view of
this, ESCELSA management decided to record immediately the amount to be
returned, the effects of which are presented in Note 4.2

2. ICMS on subvention to low income consumer

Based on Espirito Santo Finance Secretariat Normative Opinion 03/2003 of
November 24, 2003, which declared that the subvention conceded by the Federal
Government to low income consumers is ICMS taxable, management determined the
provisioning of the possible tax liability in the amount of R$ 10,351 thousand
in December 2003.

On September 30, ICMS Agreement 78/04 was published in the Official Gazette,
authorizing the states of Espirito Santo and Mato Grosso do Sul, among others,
to dispense with ICMS incidence calculated in the period from May 1, 2002 to
February 29, 2004 by reason of the subvention.

As a consequence the provision was reversed in December 2003.


3. Equity in the results

a) The results of subsidiary ENERSUL were positively impacted by the recognition
of the tax effects in the amount of R$ 25,575 thousand arising from the use of
the provisions for reduction to market value of the UTE Campo Grande turbine,
sold on September 22, 2004.

Consequently, ESCELSA recognized equity in the results from its subsidiary
MAGISTRA (parent company of ENERSUL) of R$ 17,781 thousand.

b) ENERSUL adopted identical procedures for reversal of the ICMS provision for
low income consumers, described in item 2, recording R$ 4,590 thousand, and also
recording in ESCELSA a positive equity in the results of R$ 2,993 thousand.

Gross Operating Revenue

Gross operating revenue up to the 3rd quarter of 2004 was R$ 1,077,596 thousand,
a 11.9% increase compared to the same period of the previous year. The following
factors contributed to this: i) an increase in supply revenues and the supply of
electrical energy, which reached R$ 57,326 thousand, 6.5% higher than the
previous year, despite negative market growth of 5.3%, compensated by a tariff
adjustment of 17.3% in August 2003; ii) an increase in the emergency capacity
charge; iii) an increase in the tariff for the use of the transmission and
distribution system and the number of free customers, whose tariff was
readjusted in August 2003, contributing to the maintenance of margins. The
reduction in other revenue is due to an agreement signed in March 2003, with a
customer, to settle a judicial claim.

Net operating revenue up to the 3rd quarter of 2004 totaled R$ 728,851 thousand,
8.6% higher than the same period in 2003. The breakdown of customers, per class,
is the following:

OPERATING COSTS

Operating costs, which include operating expenses plus the RGR quota, reached R$
646,064 thousand up to the end of the 3rd quarter of 2004, compared to R$
597,446 thousand during the same period in the previous year, an increase of
8.1%.

Costs manageable by the company decreased 9.2%, from R$ 169,356 thousand on
September 30, 2003 to R$ 153,708 thousand on September 30, 2004. Depreciation
increased 3.1%. The main variations were:

a) Personnel - increase due to the repercussion of the adjustment granted in
August/2003, the application of the compensation policy and the collective
bargaining agreement of November 2003, compensated by higher amounts of costs
transferred to investments;

b) Material - increase in the use of materials for the renovation of
transformers, acquisitions of meter seals, connections, cuts and reconnections;

c) Third party services - increase in costs related to cuts, consumer unit
inspections, reconnection, call center services, meter readings and delivery of
billing statements and maintenance of transmission lines and distribution
networks, consulting, legal services and environment;

d) Provision for Contingencies - the decrease in 2004 is due, in fact, to the
recording of tax contingencies in 2003;

e) Other - the reduction in this account is due to a smaller allowance for
doubtful accounts, a reduction in the amount of the energy conservation program
and reversal of the ICMS provision for low income consumers.

The operating costs that the Company does not manage, increased 15.0%, mainly
attributable to the increase of purchased energy expense, costs of connection of
the basic network, besides the payment of the Energy Development Fund (CDE)
created in 2003, and the costs with the Rationing of Electric Energy Program
which are being recognized in the tariff.

The reduction of Furnas /Tractbel amounts is due to cancellations of initial
contracts at the rate of 25% per annum. The necessity was contracted with other
suppliers. The reduction of Itaipu amounts is due to the deferral of the CVA
account established by ANEEL over 24 months as from August 2004.

Financial Result

The financial result up to the 3rd quarter of 2004 was negative by R$ 104,131
thousand, compared to positive of R$ 164,639 thousand for the same period in
2003. The negative result up to the 3rd quarter arose because of the devaluation
of the Brazilian Real against the U.S. dollar, while, in the same prior-year
period, the appreciation of the Real resulted in exchange gains. Financial
revenue decreased due to the lower level of financial investments.

Results for the period

A significant factor in the calculation of the profit of R$ 47,504 thousand up
to 3rd quarter 2004 was the financial result, in part offset by the positive
result of the holding in MAGISTRA of R$ 57,783 thousand, as well as the reversal
of provisions for IRPJ and CSSL in view of the tax losses.

Available Resources

ESCELSA had available resources on September 30, 2004 deposited with banking
institutions or invested in the financial market in the amount of R$ 202,095
thousand and consolidated of R$ 265,153 thousand as shown below:

     Report of Independent Accountants on the Limited Review of Quarterly

     To the Board of Directors and Stockholders
     Espirito Santo Centrais Eletricas S.A.




1    We have carried out limited reviews of the accounting information included
     in the Quarterly Information (ITR) of Espirito Santo Centrais Eletricas
     S.A. - ESCELSA and of Espirito Santo Centrais Eletricas S.A. - ESCELSA and
     its subsidiaries for the quarters and periods ended September 30 and June
     30, 2004. This information is the responsibility of the Company's
     management.

2    Our reviews were carried out in accordance with specific standards
     established by the Institute of Independent Auditors of Brazil (IBRACON),
     in conjunction with the Federal Accounting Council (CFC), and mainly
     comprised: (a) inquiries of and discussions with management responsible for
     the accounting, financial and operating areas of the Company with regard to
     the main criteria adopted for the preparation of the quarterly information
     and (b) a review of the significant information and of the subsequent
     events which have, or could have, significant effects on the Company's
     financial position and operations.

3    Based on our limited reviews, we are not aware of any material
     modifications that should be made to the quarterly information referred to
     above in order that such information be stated in accordance with the
     accounting practices adopted in Brazil applicable to the preparation of
     quarterly information, consistent with the Brazilian Securities Commission
     (CVM) regulations.
