                   Notes to Consolidated Financial Statements

                             June 30, 2004 and 2003

                                   (Unaudited)

(1)  Summary of Significant Accounting Policies and Basis of Presenting
     Consolidated Financial Statements

     (a)  Description of Business

          Korea Electric Power Corporation (KEPCO or the "Company") was
          incorporated on January 1, 1982 in accordance with the Korea Electric
          Power Corporation Act (the "KEPCO Act") to engage in the generation,
          transmission and distribution of electricity and development of
          electric power resources in the Republic of Korea. KEPCO was given a
          status of government-invested enterprise on December 31, 1983
          following the enactment of the Government-Invested Enterprise
          Management Basic Act. KEPCO's stock was listed on the Korea Stock
          Exchange on August 10, 1989 and the Company listed its Depository
          Receipts (DR) on the New York Stock Exchange on October 27, 1994.

          As of June 30, 2004, the Government of the Republic of Korea, Korea
          Development Bank and foreign investors hold 27.03%, 26.93% and 29.61%,
          respectively, of KEPCO's shares.

          KEPCO spun off its power generation division on April 2, 2001,
          resulting in the establishment of six new power generation
          subsidiaries. The Company has been considering the gradual
          privatization of the Company's power generation subsidiaries and
          distribution business, which is in accordance with the restructuring
          plan, dated January 21, 1999, of the electricity industry in the
          Republic of Korea announced by the Ministry of Commerce, Industry and
          Energy ("Restructuring Plan"). This Restructuring Plan, which is
          intended to introduce a competitive system in the electricity
          industry, is expected to affect the determination of utility rates,
          result in changes in management structure, related laws and
          regulations, and affect electricity supply and demand policy.

     (b)  Basis of Presenting Consolidated Financial Statements

          KEPCO maintains its accounting records in Korean Won and prepares the
          consolidated financial statements in the Korean language (Hangul) in
          conformity with the Korea Electric Power Corporation Act ("KEPCO
          Act"), the Accounting Regulations for Government Invested Enterprises,
          which have been approved by the Korean Ministry of Finance and Economy
          and, in the absence of specialized accounting regulations for utility
          companies, the accounting principles generally accepted in the
          Republic of Korea. Certain accounting principles applied by the
          Company that conform with financial accounting standards and
          accounting principles in the Republic of Korea may not conform with
          generally accepted accounting principles in other countries.
          Accordingly, these financial statements are intended for use only by
          those who are informed about Korean accounting principles and
          practices, KEPCO Act and Accounting Regulations for Government
          Invested Enterprises. The accompanying financial statements have been
          condensed, restructured and translated into English (with certain
          expanded descriptions) from the Korean language financial statements.

          Certain information included in the Korean language financial
          statements, but not required for a fair presentation of the Company's
          financial position, results of operations or cash flows, is not
          presented in the accompanying financial statements.

                   Notes to Consolidated Financial Statements

(1)  Summary of Significant Accounting Policies and Basis of Presenting
     Consolidated Financial Statements, Continued

     (b)  Basis of Presenting Consolidated Financial Statements, Continued

          Effective January 1, 2004, the Company adopted Statements of Korea
          Accounting Standards No. 10, 12 and 13. The adoption of these
          standards did not have any impact on the accompanying financial
          statements.

          The consolidated financial statements include the accounts of KEPCO
          and controlled subsidiaries (collectively referred to as the
          "Company") as of December 31, 2003 and June 30, 2004. Controlled
          subsidiaries include majority-owned entities be either the Company or
          controlled subsidiaries and other entities where the Company or its
          controlled subsidiary owns more than 30% of total outstanding common
          stock and is the largest shareholder. Investments in affiliates in
          which KEPCO is able to exercise significant influence over the
          operating and financial policies of the investee are accounted for
          using the equity method. Significant influence is deemed to exist when
          the investor owns more than 20 % of the investee's voting shares
          unless there is evidence to the contrary.

          Investments of KEPCO and equity accounts of subsidiaries subject to
          consolidation were eliminated at the dates KEPCO obtained control of
          the subsidiaries. Any difference between the cost of acquisition and
          the book value of the subsidiary is recorded as either goodwill or
          negative goodwill. Goodwill is amortized using the straight-line
          method within twenty years from the year the acquisition occurred.
          Negative goodwill is recovered, within the limit of the aggregate fair
          values of identifiable non-monetary assets, using the straight-line
          method over weighted-average years of depreciable assets and the
          amounts in excess of the limit are charged to current operations and
          presented as extraordinary gain at the acquisition date.

          Intercompany receivables and payables including trade receivables and
          trade payables are eliminated. Profits and losses on intercompany
          sales of products, property or other assets are eliminated in the
          consolidated financial statements based on the gross profit or loss
          recognized. For sales from KEPCO to subsidiaries (downstream sales),
          the full amount of intercompany gain or loss is eliminated in the
          consolidated income. For upstream sales, the elimination is allocated
          proportionately to consolidated income and minority interests.

     (c)  Property, Plant and Equipment

          Property, plant and equipment are stated at cost, except in the case
          of revaluation made in accordance with the KEPCO Act and the Assets
          Revaluation Law of Korea. Plant and equipment under capital leases are
          stated at an amount equal to the lower of their fair value or the
          present value of minimum lease payments at inception of lease.
          Significant additions or improvements extending useful lives of assets
          are capitalized. However, normal maintenance and repairs are charged
          to expense as incurred.

          The Company capitalizes interest cost and other financial charges on
          borrowing associated with the manufacture, purchase, or construction
          of property, plant and equipment, incurred prior to completing the
          acquisition, as part of the cost of such assets. The calculation of
          capitalized interest includes exchange differences arising from
          foreign borrowings to the extent that they are regarded as an
          adjustment to interest costs, which is limited to the extent of
          interest cost calculated by the weighted average interest rate of
          local currency borrowings. For the six-month periods ended June 30,
          2003 and 2004, the amounts of capitalized interest were KRW
          252,639 million and KRW 160,619 million, respectively. The foreign
          currency transactions and translation gains excluded from the
          calculation of capitalized interest rate amounted to KRW
          124,520 million and foreign currency transaction and translation loss
          added to the calculation of capitalized interest rate amounted to KRW
          24,323 million for the six-month period ended June 30, 2004.

          Depreciation is computed by the declining-balance method
          (straight-line method for buildings and structures, unit-of-production
          method and straight-line method for nuclear fuel) using rates based on
          the estimated useful lives described in the Korean Corporate Income
          Tax Law and as permitted under the Accounting Regulations for
          Government Invested Enterprises as follows:

                       Estimated useful life
                       ---------------------
          Buildings            8~ 30
          Structures           8~ 30
          Machinery              16
          Vehicles               4
          Others                4, 9

          KEPCO records the following funds and materials, which relate to the
          construction of transmission and distribution facilities as
          construction grants:

          .    Grants from the government or public institutions
          .    Funds, construction materials or other items contributed by
               customers

          Construction grants are initially recorded and presented in the
          accompanying financial statements as deductions from the assets
          acquired under such grants and are offset against depreciation expense
          during the estimated useful lives of the related assets. The Company
          received KRW 280,086 million and KRW 282,616 million of construction
          grants, and offset KRW 61,993 million and KRW 71,424 million against
          depreciation expense, and KRW 18,274 million and KRW 18,333 million
          against utility plant removal cost for the six-month periods ended
          June 30, 2003 and 2004, respectively.

     (d)  Leases

          The Company accounts for and classifies its lease transactions as
          either operating or capital leases, depending on the terms of the
          lease under Korea Lease Accounting Standards. If a lease is
          substantially noncancellable and meets any of the criteria listed
          below, the present value of future minimum lease payments is reflected
          as an obligation under capital lease.

          .    Ownership of the leased property shall be transferred to the
               lessee at the end of the lease term without additional payment or
               for a contract price.

          .    The lease has a bargain purchase option.

          .    The lease term is equal to 75% or more of the estimated economic
               useful life of the leased property.

          .    The present value at the beginning of the lease term of the
               minimum lease payments equals or exceeds 90% of the fair value of
               the leased property.

          If the above criteria are not met, the lease is classified as an
          operating lease and lease payments are expensed on a straight-line
          basis over the lease term.

     (e)  Investments in Securities

          Debt and equity securities are classified into one of the three
          categories of held-to-maturity, available-for-sale, or trading
          securities at the time of acquisition and such determination is
          reassessed at each balance sheet date. Investments in debt securities
          that the Company has the positive intent and ability to hold to
          maturity are classified as held-to-maturity. Securities that are
          bought and held principally for the purpose of selling them in the
          near term (thus held for only a short period of time) are classified
          as trading securities. Trading generally reflects active and frequent
          buying and selling, and trading securities are generally used to
          generate profit on short-term differences in price. Investments not
          classified as either held-to-maturity or trading securities are
          classified as available-for-sale securities.

          Trading securities are carried at fair value, with unrealized holding
          gains and losses included in earnings. Available-for-sale securities
          are carried at fair value, with unrealized holding gains and losses
          reported as a capital adjustment. Investments in equity securities
          that do not have readily determinable fair values are stated at cost.
          Declines in value judged to be other-than-temporary on
          available-for-sale securities are charged to current results of
          operations. Investments in debt securities that are classified into
          held-to-maturity are reported at amortized cost at the balance sheet
          date and such amortization is included in interest income.

          Marketable securities are at the quoted market prices as of the period
          end. Non-marketable debt securities are recorded at the fair values
          derived from the discounted cash flows by using an interest rate
          deemed to approximate the market interest rate. The market interest
          rate is determined by the issuers' credit rate announced by the
          accredited credit rating agencies in Korea. Money market funds are
          recorded at the fair value determined by the investment management
          companies.

          Trading securities are classified as current assets, whereas
          available-for-sale securities and held-to-maturity securities are
          classified as long-term investments. However, available-for-sale
          securities whose maturity dates are due within one year from the
          balance sheet date or whose likelihood of being disposed of within one
          year from the balance sheet date is probable are classified as current
          assets. Likewise, held-to-maturity securities whose maturity dates are
          due within one year from the balance sheet date are classified as
          current assets.

     (f)  Investment Securities under the Equity Method of Accounting

          Investments in affiliated companies owned 20% or more or of which the
          Company is able to exercise significant influence over the operating
          and financial policies are stated at an amount as determined using the
          equity method. Under the equity method of accounting, the Company's
          initial investment is recorded at cost and is subsequently increased
          to reflect the Company's share of the investee income and reduced to
          reflect the Company's share of the investee losses or dividends
          received. Any excess in the Company's acquisition cost over the
          Company's share of the investee's identifiable net assets is generally
          recorded as goodwill or other intangibles and amortized by the
          straight-line method over the estimated useful life. The amortization
          of goodwill is recorded against the equity income of affiliates. When
          events or circumstances indicate that carrying amount may not be
          recoverable, the Company reviews goodwill for any impairment.

          Under the equity method of accounting, the Company does not record its
          share of losses of affiliate companies when such losses would make the
          Company's investment in such entity less than zero.

     (g)  Intangible Assets

          Intangible assets are stated at cost less accumulated amortization, as
          described below.

          (i)  Research and Development Costs

               Expenditure on research activities, undertaken with the prospects
               of gaining new scientific or technical knowledge and
               understanding, is recognized in the statement of income as an
               expense as incurred.

               Expenditure on development incurred in conjunction with new
               products or technologies, in which the elements of costs can be
               identified and future economic benefits are clearly expected, is
               capitalized and amortized on a straight-line basis over 5 years.
               The capitalized expenditure includes the cost of materials,
               direct labor and an appropriate proportion of overheads.

          (ii) Other Intangible Assets

               Other intangible assets, which consist of industrial rights, land
               rights and others, are stated at cost less accumulated
               amortization and impairment losses. Such intangible assets are
               amortized using the straight-line method over a reasonable
               period, from 4 years to 50 years, based on the nature of the
               asset.

     (h)  Cash Equivalents

          The Company considers short-term financial instruments with maturities
          of three months or less at the acquisition date to be cash
          equivalents.

     (i)  Financial Instruments

          Short-term financial instruments are financial instruments handled by
          financial institutions which are held for short-term cash management
          purposes or will mature within one year, including time deposits,
          installment savings deposits and restricted bank deposits.

     (j)  Allowance for Doubtful Accounts

          Allowance for doubtful accounts is estimated based on an analysis of
          individual accounts and past experience of collection.

     Consolidated Financial Statements, Continued

     (k)  Inventories

          Inventories are stated at the lower of cost or net realizable value,
          cost being determined using the weighted average method for raw
          materials, moving average method for supplies and specific
          identification method for other inventories. The Company maintains
          perpetual inventory records, which are adjusted through physical
          counts at the end of year.

          Effective January 1, 2004, the Company adopted Statement of Korea
          Accounting Standards No. 10, "Inventories". Through 2003, a valuation
          loss incurred when the market value of inventory falls below its
          carrying amount was reported as non-operating expense. In 2004, in
          accordance with SKAS No. 10, the Company included inventory valuation
          loss in operating expenses.

     (l)  Long-Lived Assets

          The Company reviews for the impairment of long-lived assets, whenever
          events or changes in circumstances indicate that the carrying amount
          of an asset may not be recoverable. An impairment loss would be
          recognized when estimated undiscounted future net cash flows expected
          to result from the use of the asset and its eventual disposition are
          less than its carrying amount. If such assets are considered to be
          impaired, the impairment to be recognized is measured at the amount by
          which the carrying amount of the assets exceeds the fair value of the
          assets.

          In 2001, the Company recognized an impairment loss on property, plant
          and equipment in the Youngwol an Busan thermal plant amounting to
          KRW 11,206 million, which is the difference between the carrying
          amount and recoverable value considering future cash flows.

     (m)  Valuation of Receivables and Payables at Present Value

          Receivables and payables arising from long-term installment
          transactions, long-term cash loans/borrowings and other similar
          loan/borrowing transactions are stated at present value. The
          difference between nominal value and present value is deducted
          directly from the nominal value of related receivables or payables and
          is amortized using the effective interest method. The amount amortized
          is included in interest expense or interest income.

          When the conversion rights are exercised during an accounting period,
          the value of common shares issued pursuant to the exercise shall be
          measured based on the carrying amount of the convertible bonds
          determined on the actual date such rights have been exercised.

     (n)  Convertible Bonds

          When issuing convertible bonds or bonds with stock purchase warrants,
          the values of the conversion rights or stock warrants shall be
          recognized separately. Considerations for conversion rights or stock
          warrants shall be measured by deducting the present value of ordinary
          or straight debt securities from the gross proceeds of the convertible
          bonds or bonds with stock purchase warrants received at the date of
          issue.

          The value of the common shares issued pursuant to the exercise of the
          conversion rights shall be measured as the sum of the carrying amount,
          at the time of conversion, and the amount of consideration received
          for such rights, at the time of issuance, of those convertible bonds
          that are actually related to the exercise.

     (o)  Discount (Premium) on Debentures

          Discount (premium) on debenture issued, which represents the
          difference between the face value and issuance price of debentures, is
          amortized using the effective interest rate method over the life of
          the debentures. The amount amortized is included in interest expense.

     (p)  Retirement and Severance Benefits

          Employees and directors who have been with the Company for more than
          one year are entitled to lump-sum payments based on current rates of
          pay and length of service when they leave the Company. The Company's
          estimated liability under the plan which would be payable if all
          employees left on the balance sheet date is accrued in the
          accompanying balance sheets. A portion of the liability is covered by
          an employees' severance benefit insurance where the employees have a
          vested interest in the deposit with the insurance company. Therefore,
          such deposit for severance benefit insurance amounting to KRW 82,771
          million and KRW 82,456 million as of December 31, 2003 and June 30,
          2004 are reflected in the accompanying consolidated balance sheets as
          a deduction of the liability for retirement and severance benefits.

          Through March 1999, under the National Pension Scheme of Korea, the
          Company transferred a certain portion of retirement allowances of
          employees to the National Pension Fund. The amount transferred will
          reduce the retirement and severance benefit amount to be payable to
          the employees when they leave the Company and is accordingly reflected
          in the accompanying financial statements as a reduction from the
          retirement and severance benefit liability. Since April 1999, however,
          a new regulation applies and such transfers to the National Pension
          Fund are no longer required.

     (q)  Reserve for Decommissioning Costs and Self-Insurance

          Under the Korean Electricity Business Act (EBA) Article 94, the
          Company is required to accrue for the decommissioning of nuclear
          facilities and dismantling of radioactive waste. In addition, under
          the Korean Atomic Energy Act (AEAC), an entity which constructs and
          operates a nuclear power reactor and related facilities must obtain
          permission from the Korean Minister of Science and Technology (MOST).

          The Company accrues for estimated decommissioning costs of nuclear
          facilities based on engineering studies and the expected
          decommissioning dates of the nuclear power plant. The expected
          decommissioning date is approximately 25 years from initial operation.
          However, the service period of the nuclear power plant is dependent
          upon the economy and safety of plant operation and supervision of MOST
          with periodic safety inspections and safety review.

          As of December 31, 2003 and June 30, 2004, the Company has accrued KRW
          5,091,070 million and KRW 5,399,206 million for the costs of
          dismantling and decontaminating existing nuclear power plants,
          consisting of dismantling costs of nuclear plant and dismantling costs
          of spent fuel and radioactive waste. Annual additions to the reserve
          are in amounts such that the current costs would be fully accrued for
          at estimated dates of decommissioning on a straight-line basis,
          reflecting the inflation rate. The Company accrued KRW 312,756 million
          and KRW 313,585 million as the reserve for decommissioning costs for
          the six-month period ended June 30, 2003 and 2004, respectively.

          The Company estimates its reserve for decommissioning costs based on
          engineering studies provided by a third party and applies it
          prospectively. As a result of changes of estimates, for the year ended
          December 31, 2003, the provision for decommissioning costs increased
          by KRW 72,888 million and operating income and net income decreased by
          KRW 72,888 million and KRW 52,844 million, respectively.

          In accordance with SKAS No. 5 - "Tangible Assets", the Company is
          required to recognize the fair value of a liability for an asset
          retirement obligation (e.g., dismantlement or restoration costs) in
          the period in which it is incurred. The fair value could be estimated
          based on the present value of the estimated future cash outflows
          required to satisfy the liabilities and would be discounted using a
          current credit risk-adjusted interest rate. The accretion of the
          liability due to the passage of time is recognized each period as
          expense until the settlement of the liability. Upon initial
          recognition of a liability for an asset retirement obligation, an
          asset retirement cost shall be capitalized by increasing the carrying
          amount of the related tangible asset by the same amount as the
          liability. That asset retirement cost is allocated to expense using a
          systematic and rational method over its useful life. As permitted
          under SKAS No. 5, the Company applies the accounting for asset
          retirement obligation only to assets acquired after December 31, 2002.

          In accordance with the Accounting Regulations for Government Invested
          Enterprises, KEPCO provides a self-insurance reserve for loss from
          accident and liability to third parties that may arise in connection
          with KEPCO's non-insured facilities. Payments made to settle
          applicable claims and damages are charged to this reserve.

     Consolidated Financial Statements, Continued

     (r)  Foreign Currency Translation

          KEPCO and its domestic subsidiaries maintain their accounts in Korean
          Won. Transactions in foreign currencies are recorded in Korean Won
          based on the prevailing rates of exchange on the transaction date.
          Monetary assets and liabilities denominated in foreign currencies are
          translated into Korean Won at the balance sheet date, with the
          resulting gains and losses recognized in current results of
          operations. Monetary assets and liabilities denominated in foreign
          currencies are translated into Korean Won at KRW1,152.5 to US$1, the
          rate of exchange on June 30, 2004 that is permitted by the Financial
          Accounting Standards. Non-monetary assets and liabilities denominated
          in foreign currencies, which are stated at historical cost, are
          translated into Korean Won at the foreign exchange rate ruling at the
          date of the transaction.

          Foreign currency assets and liabilities of foreign-based operations
          and the Company's overseas subsidiaries are translated at current rate
          of exchange at the balance sheet date while profit and loss items in
          the statement of income are translated at average rate and capital
          account at historical rate. The translation gains and losses arising
          from collective translation of the foreign currency financial
          statements of foreign-based operations and the Company's overseas
          subsidiaries are offset and the balance is accumulated as a capital
          adjustment.

     (s)  Derivatives

          All derivative instruments are accounted for at fair value with the
          valuation gain or loss recorded as an asset or liability. If the
          derivative instrument is not part of a transaction qualifying as a
          hedge, the adjustment to fair value is reflected in current
          operations. The accounting for derivative transactions that are part
          of a qualified hedge based both on the purpose of the transaction and
          on meeting the specified criteria for hedge accounting differs
          depending on whether the transaction is a fair value hedge or a cash
          flow hedge. Fair value hedge accounting is applied to a derivative
          instrument designed as hedging the exposure to changes in the fair
          value of an asset or a liability or a firm commitment (hedged item)
          that is attributable to a particular risk. The gain or loss on the
          hedging derivative instruments and on the hedged item attributable to
          the hedged risk is reflected in current operations. Cash flow hedge
          accounting is applied to a derivative instrument designated as hedging
          the exposure to variability in expected future cash flows of an asset
          or a liability or a forecasted transaction that is attributable to a
          particular risk. The effective portion of gain or loss on a derivative
          instrument designated as a cash flow hedge is recorded as a capital
          adjustment and the ineffective portion is recorded in current
          operations. The effective portion of gain or loss recorded as a
          capital adjustment is reclassified to current earnings in the same
          period during which the hedged forecasted transaction affects
          earnings. If the hedged transaction results in the acquisition of an
          asset or the incurrence of a liability, the gain or loss in capital
          adjustment is added to or deducted from the asset or the liability.

     (t)  Contingent Liabilities

          Contingent losses are generally recognized as a liability when
          probable and reasonably estimable.

     (u)  Revenue Recognition

          The Company recognizes revenue from the sale of electric power based
          on meter readings made on a monthly basis. The Company does not accrue
          revenue for power sold after the meter readings but prior to the end
          of the accounting period. The Company recognizes revenue on long-term
          contacts, which are related to the construction of power plants in the
          Democratic People's Republic of Korea (North Korea), based on the
          percentage-of-completion method. Revenue other than sale of electric
          power and revenue on long-term contracts is recognized when the
          Company's revenue-earning activities have been substantially
          completed, the amount of revenue can be measured reliably, and it is
          probable that the economic benefits associated with the transaction
          will flow to the Company.

     (v)  Income Taxes

          Income tax on the earnings or loss for the period comprises current
          and deferred tax. Income tax is recognized in the statement of income
          except to the extent that it relates to items recognized directly to
          equity, in which case it is recognized in equity.

          Deferred tax is provided using the asset and liability method,
          providing for temporary differences between the carrying amounts of
          assets and liabilities for financial reporting purposes and the
          amounts used for taxation purposes. The amount of deferred tax
          provided is based on the expected manner of realization or settlement
          of the carrying amount of assets and liabilities, using tax rates
          enacted or substantially enacted at the balance sheet date.

          Deferred tax assets are recognized only to the extent that it is
          probable that future taxable earnings will be available against which
          the unused tax losses and credits can be utilized. Deferred tax assets
          are reduced to the extent that it is no longer probable that the
          related tax benefit will be realized.

     (w)  Dividends payable

          Dividends are recorded when approved by the board of director and
          shareholders.

     (x)  Prior Period Adjustments

          Prior period adjustments resulting from other than fundamental errors
          are charged or credited to result of operations for the current
          period. The fundamental errors are defined as errors with such a
          significant effect on the financial statements for one or more prior
          periods that those financial statements can no longer be considered to
          have been reliable at the date of their issue. The prior period
          adjustments resulting from the fundamental errors are charged or
          credited to the beginning balance of retained earnings, and the
          financial statements of the prior year are restated.

     (y)  Earnings Per Share

          Earnings per common share are calculated by dividing net earnings by
          the weighted-average number of shares of common stock outstanding
          during each period.

     (z)  Minority Interest in Consolidated Subsidiaries

          Minority interest in consolidated subsidiaries is presented as a
          separate component of stockholders' equity in the consolidated balance
          sheets.

     (aa) Use of Estimates

          The preparation of consolidated financial statements in accordance
          with accounting principles generally accepted in the Republic of Korea
          requires management to make estimates and assumptions that affect the
          amounts reported in the financial statements and related notes to
          financial statements. Actual results could differ from those
          estimates.

(2)  Basis of Translating Consolidated Financial Statements

     The consolidated financial statements are expressed in Korean Won and,
     solely for the convenience of the reader, the consolidated financial
     statements as of and for the six-month ended period June 30, 2004, have
     been translated into United States dollars at the rate of KRW1,156.0 to
     US$1, the noon buying rate in the City of New York for cable transfers in
     won as certified for customs purposes by the Federal Reserve Bank of New
     York as of June 30, 2004. The translation should not be construed as a
     representation that any or all of the amounts shown could be converted into
     U.S. dollars at this or any other rate.

(3)  Property, Plant and Equipment

     (a)  Asset revaluation

          KEPCO revalued its property, plant and equipment in accordance with
          the KEPCO Act and the Asset Revaluation Law (the latest revaluation
          date was January 1, 1999), and recorded a revaluation gain of
          KRW12,552,973 million as a reserve for asset revaluation, a component
          of capital surplus.

(12) Appropriated Retained Earnings, Continued

     The KEPCO Act requires the Company to appropriate a legal reserve equal to
     at least 20 percent of net income for each accounting period until the
     reserve equals 50 percent of the common stock. The legal reserve is not
     available for cash dividends; however, this reserve may be credited to
     paid-in capital or offset against accumulated deficit by the resolution of
     the shareholders.

     Under the Special Tax Treatment Control Law, investment tax credit was
     allowed for certain investments. The Company was, however, required to
     appropriate from retained earnings the amount of tax benefits obtained and
     transfer such amount into a reserve for business rationalization. Effective
     December 11, 2002, the Company is no longer required to establish a reserve
     for business rationalization despite tax benefits received for certain
     investments and, consequently, the existing balance is now regarded as a
     voluntary reserve.

     The reserves for the investment on social overhead capital and research and
     human development are appropriated by the Company to avail itself of
     qualified tax credits to reduce corporate tax liabilities. This reserve is
     not available for cash dividends for a certain period as defined in the Tax
     Incentive Control Law.

(28) Employee Welfare and Contributions to Society

     For employee welfare, the Company maintains a refectory, an infirmary,
     athletic facilities, a scholarship fund, workmen's accident compensation
     insurance, unemployment insurance and medical insurance.

     The Company donated KRW 40,490 million and KRW 87,958 million to the fund
     for the welfare of the Company's employees and others for the six-month
     periods ended June 30, 2004 and 2003, respectively.

(29) Economic Environment

     In common with other Asian countries, the economic environment in the
     Republic of Korea continues to be volatile. In addition, the Korean
     government and the private sector continue to implement structural reforms
     to historical business practices including corporate governance. The
     Company may be either directly or indirectly affected by these economic
     conditions and the reform program described above. The accompanying
     consolidated financial statements reflect management's assessment of the
     impact to date of the economic environment on the financial position and
     results of operations of the Company. Actual results may differ materially
     from management's current assessment.

(30) Reconciliation to United States Generally Accepted Accounting Principles

     The accompanying consolidated financial statements are prepared in
     accordance with generally accepted accounting principles in the Republic of
     Korea ("Korean GAAP") which differ in certain respects from accounting
     principles generally accepted in the United States of America ("U.S.
     GAAP"). The significant differences between Korean GAAP and U.S. GAAP that
     affect the Company's financial statements are described below. Other
     differences do not have a significant effect on either consolidated net
     earnings or stockholders' equity.

     (a)  Asset Revaluation and Depreciation

          Under Korean GAAP, assets revaluation was allowed before 2000.
          However, under U.S. GAAP, assets revaluation has not been allowed and
          accordingly property, plant and equipment must be stated at cost less
          accumulated depreciation. The effect of revaluation of property, plant
          and equipment and the resulting depreciation of revalued amounts are
          reversed out for U.S. GAAP reporting purposes.

     (b)  Special Depreciation

          Under Korean GAAP, special depreciation, which was recognized prior to
          1994, represents an acceleration of depreciation on certain energy
          saving and anti-pollution facilities and equipment. However, this is
          not in accordance with U.S. GAAP. Accordingly, U.S. GAAP
          reconciliation reflects the reversal of special depreciation effect.

     (c)  Accounting for Regulation

          Under U.S. GAAP regulations for the establishment of electric rates
          consider, in certain cases, certain income and expenses to be
          recognized in different years than they are recognized for financial
          reporting. In accordance with SFAS No. 71 - "Accounting for the
          Effects of Certain Types of Regulation" for regulated enterprises, a
          regulatory liability or regulatory asset is recognized on the
          consolidated balance sheet by a charge or credit to operations to
          match revenues and expenses. These assets or liabilities relate to the
          adjustments for foreign currency translation, reserve for
          self-insurance and deferred income taxes described below.

          The following table shows the components of regulated assets and
          liabilities as of December 31, 2003 and June 30, 2004.



                                                                       U.S. dollars (note 2)

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


          As discussed below, such adjustments exclude those relating to the
          non-regulated subsidiaries and affiliates of the Company.

          As discussed in Note 1, on April 2, 2001, six new power generation
          subsidiaries were established in accordance with the Restructuring
          Plan. Since the power generation subsidiaries' rates are determined by
          a competitive system that is not cost based, they no longer meet the
          criteria for application of SFAS No. 71. The power transmission and
          distribution divisions of KEPCO continue to meet the criteria for
          application of SFAS No. 71.

          U.S. GAAP reconciliation summarized in note (30) (o) reflects the
          elimination of such regulation effects that was recognized as
          regulatory assets and liabilities pursuant to SFAS No 71. The effect
          of this change has been recognized in current operations, resulting in
          the increase in net income under U.S. GAAP of (Won) 423,146
          million, in accordance with SFAS No. 101 - "Accounting for the
          Discontinuation of Application of SFAS No 71". However, in accordance
          with SFAS No. 101, the carrying amounts of property, plant and
          equipment measured and reported pursuant to SFAS No. 71 were not
          adjusted since they were not impaired under the provisions of SFAS No.
          121 - "Accounting for the Impairment of Long-Lived Assets and for
          Long-Lived Assets to be Disposed Of".

          The Government of the Republic of Korea approves the rates that KEPCO
          charges to its customers. KEPCO's utility rates are designed to
          recover its reasonable costs plus a fair investment return. In June
          2001, the Ministry of Commerce, Industry and Energy announced the
          revised guidelines for utility rate setting, stating that
          non-operating expenses should be excluded from reasonable costs while
          income tax expense (including deferred income taxes), instead of
          income tax payables, should be included for rate-making purposes. As a
          result of this guideline change and the deregulation of the power
          generation subsidiaries, only KEPCO's deferred income taxes caused by
          the difference between Korean GAAP and U.S. GAAP are subject to SFAS
          No. 71, to the extent that tax benefits or obligation will affect
          future allowable costs for rate-making purposes.

     Continued

     (c)  Accounting for Regulation, Continued

          Regulatory assets and liabilities are established based on the current
          regulations and rate-making process. Accordingly, these assets and
          liabilities may be significantly changed due to the potential future
          deregulation or changes in the rate-making process.

          Korean GAAP does not have accounting standards specifying for
          regulated enterprises such as SFAS 71 under U.S. GAAP.

     (d)  Reversal of Eliminated Profit on Transactions with Subsidiaries and
          Affiliated Companies

          Under Korean GAAP, KEPCO's share of the profit on transactions between
          KEPCO and its affiliated companies is eliminated in the preparation of
          the consolidated financial statements. No elimination of such profit
          is required to be in accordance with U.S. GAAP for regulated
          enterprises, where the sales prices are reasonable and it is probable
          that, through the rate-making process, future revenues approximately
          equal to the sales price will result from KEPCO's use of the utility
          plant. KEPCO meets both of these criteria, and no elimination of
          profit on transactions between KEPCO and its affiliated companies is
          necessary for reporting under U.S. GAAP.

     (e)  Foreign Currency Translation

          As discussed in Note 1, under Korean GAAP, the Company capitalizes
          certain foreign exchange transaction and translation gains and losses
          on borrowings denominated in foreign currency associated with
          property, plant and equipment during the construction period.

          Under U.S. GAAP, all foreign exchange transaction gains and losses
          (referred to as either transaction or translation gains (losses) under
          Korean GAAP) are included in the results of operations for the current
          period. The amounts of foreign exchange transaction and translation
          gains and losses included in property, plant and equipment under
          Korean GAAP are reversed into results of operations for the current
          period under U.S. GAAP.

          Under Korean GAAP, the convertible bond denominated in a foreign
          currency are regarded as non-monetary liabilities since they have
          equity-like characteristics, and the Company does not recognize the
          associated foreign currency translation gain or loss.

          Under U.S. GAAP, the convertible bond denominated in a foreign
          currency are translated at the rate of exchange on the balance sheet
          date, and the resulting foreign currency transaction gain or loss is
          included in the results of operations.

     (f)  Deferred Income Taxes

          As discussed in note 1, deferred tax assets and liabilities are
          recorded in the financial statements prepared in accordance with
          Korean GAAP, which is substantially the same as U.S. GAAP. For U.S.
          GAAP purposes, the Company recognizes the deferred tax assets and
          liabilities on temporary differences resulting from differences
          between Korean GAAP and U.S. GAAP.

     (g)  Asset retirement obligation

          Under SFAS No. 143 of U.S. GAAP. - "Accounting for Asset Retirement
          Obligations", the Company is required to recognize an estimated
          liability for legal obligations associated with the retirement of
          tangible long-lived assets. The Company measures the liability at fair
          value when incurred and capitalizes a corresponding amount as part of
          the book value of the related long-lived assets. The increase in the
          capitalized cost is depreciated over the estimated useful life of
          these assets. Since the fair value of the asset retirement obligations
          is determined using a present value approach, accretion of the
          liability due to the passage of time is recognized each period as
          expense until the settlement of the liability. The Company records a
          gain or loss when the liability is settled after retirement.

          This statement is effective for financial statements issued for fiscal
          years beginning after June 15, 2002 and it is to be applied to all
          existing long-lived assets including those acquired before January 1,
          2003. Accounting for asset retirement obligations under Korean GAAP is
          substantially the same as SFAS No. 143, except that those assets
          acquired before January 1, 2003 can be excluded from the application
          of the accounting for asset retirement obligation under Korean GAAP.
          Accordingly, the Company's assets acquired before January 1, 2003 were
          excluded from the application of the accounting for asset retirement
          obligation under Korean GAAP.

          As a result of the adoption of SFAS No. 143, the Company recognized
          (Won) 1,775,306 million additional pretax gain as a cumulative effect
          of accounting change on January 1, 2003.

          As explained in Note 1 (q) "Reserve for Decommissioning Costs and
          Self-Insurance", under Korean GAAP the Company has accrued
          (Won) 5,091,070 million and (Won) 5,399,206 million for the cost of
          dismantling and decontaminating existing nuclear power plants as of
          December 31, 2003 and June 30, 2004 in accordance with the Korean
          Electricity Business Act.

          For U.S. GAAP reporting purpose, the Company capitalizes asset
          retirement cost additionally and recognizes asset retirement
          obligation liability additionally as of December 31, 2003 and June 30,
          2004 is as follows:

          As of December 31, 2003 and June 30, 2004, asset retirement obligation
          amounted to KRW 4,612,930 million and KRW 4,765,561 million under U.S.
          GAAP, respectively.

     (h)  Derivatives

          Under SFAS No. 133 - "Accounting for Derivative Instruments and
          Hedging Activities", as amended by SFAS No. 138, the Company is
          required to recognize all derivatives on the consolidated balance
          sheet at fair value. Derivatives that do not qualify as a hedge must
          be adjusted to fair value through current operations. If derivatives
          qualify as a hedge, depending on the nature of the hedge, changes in
          the fair value of derivatives will either be offset against the change
          in fair value of the hedged assets, liabilities or firm commitment
          through earnings or recognized in other comprehensive income until the
          hedged item is recognized in earnings. The ineffective portion of a
          derivative's changes in fair value will be immediately recognized in
          current earnings. Derivatives accounting under Korea GAAP is
          substantially the same as SFSA No. 133.

     (i)  Convertible bonds

          Under U.S. GAAP, no portion of the proceeds from the issuance of
          convertible debt securities are accounted for as attributable to the
          conversion feature, while under Korean GAAP, the value of the
          conversion rights are recognized as capital surplus.

     (j)  Principles of Consolidation

          Under Korean GAAP, minority interests in consolidated subsidiaries are
          presented as a component of shareholder's equity in the consolidated
          balance sheet.

          Under U.S. GAAP, minority interests are presented between the
          liability section and the stockholders' equity section in the
          consolidated balance sheet.

     (k)  Reserve for self-insurance

          The Company accrues a reserve for self-insurance for non-insured
          facilities in accordance with Accounting Regulations for Government
          Invested Enterprises. U.S. GAAP considers accidental damage to be a
          contingency that is only provided for when asset has been impaired or
          a liability has been incurred.

     (l)  Comprehensive Income

          Effective January 1, 1998, the Company adopted the provision of SFAS
          No.130 under U.S.GAAP - "Reporting Comprehensive Income", which
          requires the reporting and presentation of comprehensive income and
          its components (revenues, expenses, gains and losses) for each period
          presented. Such a presentation is not required under Korean GAAP.
          Comprehensive income for the six-month periods ended June 30, 2003 and
          2004 is summarized as follows:



                                                                                       U.S. dollars (note 2)

     (m)  Fair Value of Financial Instruments

          The following methods and assumptions were used to estimate the fair
          value of each class of significant financial instruments when it is
          practicable to estimate such value:

          (i)  Cash and cash equivalents, short term financial instruments,
               trade receivables, short-term borrowings, and trade payables:

               The carrying amount approximates fair value because of the nature
               or short maturity of those instruments.

          (ii) Investments.

               The fair value of market-traded investments is estimated based on
               quoted market prices for those or similar investments. For other
               investments for which there are no quoted market prices, a
               reasonable estimate of fair value could not be made without
               incurring excessive costs.

          (iii) Long-term debt

               The fair value of long-term debt is estimated based on the quoted
               market prices for the same or similar issues or on the current
               rates offered for debt of the same remaining maturities.

          The estimated fair values of the Company's financial instruments at
          December 31, 2003 and June 30, 2004 are summarized as follow (won in
          millions):



                                                                              Won (million)

     (n)  Recent changes in U.S. GAAP

          In April 2003, the FASB issued Statement No. 149 - "Amendment of
          Statement 133 on Derivative Instruments and Hedging Activities." This
          statement amends and clarifies accounting for derivative instruments,
          including certain derivative instruments embedded in other contracts,
          and for hedging activities under Statement 133. The new guidance
          amends statement 133 regarding implementation issues raised in
          relation to the application of the definition of a derivative,
          particularly regarding the meaning of an underlying and the
          characteristics of a derivative that contains financing components.
          The amendments set forth in statement 149 improve financial reporting
          by requiring that contracts with comparable characteristics be
          accounted for similarly. In particular, this statement clarifies under
          what circumstances a contract with an initial net investment meets the
          characteristics of a derivative as discussed in statement 133. In
          addition, it clarifies when a derivative contains a financing
          component that warrants special reporting in the statement of cash
          flows. The Company does not believe that the impact will be
          significant.

          In May 2003, the FASB issued SFAS No. 150-"Accounting for Certain
          Financial Instruments with Characteristics of Both Liabilities and
          Equity". SFAS No. 150 provides guidance on how an entity classifies
          and measures certain financial instruments with characteristics of
          both liabilities and equity. SFAS No. 150 is effective for financial
          instruments entered into, or monitored after, May 31, 2003, and
          otherwise is effective at the beginning of the first interim period
          beginning after June 15, 2003. The Company does not believe that the
          adoption of this statement will have a significant impact on its
          financial condition or result of operations.

          In January and December 2003, the FASB issued and then revised FIN
          No.46-"Consolidation of Variable Interest Entities", which is
          effective immediately for all variable interest entities created after
          January 31, 2003. FIN No.46 must be applied for the first fiscal year
          or interim period ending after March 15, 2004 for variable interest
          entities or the first quarter of 2004. FIN No.46 requires existing
          unconsolidated variable interest entities to be consolidated by their
          primary beneficiaries if the entities do not effectively disperse
          risks among the parties involved. A primary beneficiary absorbs the
          majority of the entity's losses or receives a majority of the entity's
          residual returns, if they occur, or both. Where it is reasonably
          possible that the information about the variable interest entity
          relationships must be disclosed or consolidated, the Company must
          disclose the nature, purpose, size and activity of the variable
          interest entity and the maximum exposure to loss as a result of the
          Company's involvement with the variable interest entity in all
          financial statements issued after January 31, 2003. The Company does
          not believe that the adoption of this statement will have a
          significant impact on its financial condition or result of operations.

          In March 2004, the EITF reached a consensus regarding EITF 03-1, " The
          Meaning of Other-Than-Temporary Impairment and Its Application to
          Certain Investments". The consensus provides guidance for evaluating
          whether an investment is other-than-temporarily impaired. The EITF
          03-1 guidance for determining other-than-temporary will be effective
          beginning from the second half of 2004. The Company is currently
          evaluating the impact that EITF 03-1 may have on its consolidated
          financial statements.

          Effectively January 1, 2005, the statutory tax rate, including
          resident surcharge, will be changed from 29.7% to 27.5%. Enacted
          future tax rate of 27.5% was applied to calculate the deferred income
          tax liabilities of which the tax effect will be realized after 2005.

     (p)  Segment Information

          Under U.S. GAAP, a company reports segment information based on the
          disaggregation of the company by management for making operating
          decisions. Each of the Company's consolidated subsidiaries is an
          operating segment in accordance with SFAS No. 131 - "Disclosures about
          Segments of an Enterprise and Related Information". Operating segments
          that have similar economic characteristics and are similar in terms of
          the nature of their products and services, the nature of the
          production process, the type or class of customer, and methods of
          distribution have been aggregated into two reportable segments:
          transmission and distribution of electricity, and power generation,
          which are engaged in the transmission and sales of electricity, and
          production of electricity, respectively. Prior to the spin-off of the
          power generation division (see Note 1), the Company did not
          disaggregate the information for transmission and distribution of
          electricity, and power generation. Therefore, the reportable segments
          in 2000 were combined into one operating segment, the electric
          business. Operating segments that do not meet the quantitative
          thresholds of SFAS No. 131 have been combined and disclosed in an "all
          other" category. All other revenues consist primarily of the revenues
          from the engineering and maintenance for utility plant, information
          services, sales of nuclear fuel, communication line leasing and
          others.

          The accounting policies of the segments are the same as those
          described in Note 1 - Summary of Significant Accounting Policies and
          Note 30 - Reconciliation to United States Generally Accepted
          Accounting Principles. The Company evaluates performance based on net
          income. There are no revenues from transactions with a single external
          customer that amount to 10% or more of the consolidated revenues of
          the Company.
