NON-CONSOLIDATED FINANCIAL STATEMENTS

FOR THE YEAR ENDED DECEMBER 31, 2007

AND INDEPENDENT AUDITORS’ REPORT

Independent Auditors’ Report

English Translation of a Report Originally Issued in Korean

To the Shareholders and Board of Directors of

Korea Electric Power Corporation:

We have audited the accompanying non-consolidated balance sheet of Korea Electric Power Corporation (the “Company”) as of December 31, 2007, the related non-consolidated statements of income, appropriation of retained earnings, statements of cash flows and changes in shareholders’ equity for the year ended December 31, 2007, all expressed in Korean Won. These non-consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these non-consolidated financial statements based on our audit. We did not audit the financial statements of Korea South-East Power Co., Ltd., Korea Midland Power Co., Ltd., Korea Western Power Co., Ltd. and Korea Southern Power Co., Ltd., which statements reflect 14.7 percent of the total assets as of December 31, 2007 and 36.2 percent of income before income tax expenses for the year ended December 31, 2007. Those statements were audited by other auditors whose reports have been furnished to us, and our opinion, in so far as it relates to the amounts included for those companies, is based solely on the reports of the other auditors. The accompanying non-consolidated balance sheet of the company as of December 31, 2006 and the related non-consolidated statements of income, appropriations of retained earnings and cash flows for the year then ended, which are presented for comparative purposes, were audited by other auditors whose report, dated January 31, 2007, expressed an unqualified opinion on those statements.

We conducted our audit in accordance with auditing standards generally accepted in the Republic of Korea. Those standards require that we plan and perform the audit to obtain reasonable assurance as to whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audit and the report of the other auditors provide a reasonable basis for our opinion.

In our opinion, based on our audit and the reports of the other auditors, the financial statements referred to above present fairly, in all material respects, the financial position of Korea Electric Power Corporation as of December 31, 2007, and the results of its operations, the changes in its retained earnings and shareholders’ equity, and its cash flows for the year then ended in conformity with the Korea Electric Power Corporation Act, the Accounting Regulations for Public Enterprise & Associate Government Agency and accounting principles generally accepted in the Republic of Korea.

Our audit also comprehended the translation of Korean Won amounts into U.S. dollar amounts and, in our opinion, such translation has been made in conformity with the basis in Note 2. Such U.S. dollar amounts are presented solely for the convenience of readers outside of Korea.

Accounting principles and audit standards and their application in practice vary among countries. The accompanying non-consolidated financial statements are not intended to present the financial position, results of operations, cash flows and changes in shareholders’ equity in accordance with accounting principles and practices generally accepted in countries other than the Republic of Korea. In addition, the procedures and practices utilized in the Republic of Korea to audit such financial statements may differ from those generally accepted and applied in other countries. Accordingly, this report and the accompanying non-consolidated financial statements are for use by those knowledgeable about Korean accounting procedures and audit standards and their application in practice.

February 11, 2008

Certain subsequent events or circumstances may have occurred between the auditors’ report date and the time the auditors’ report is read.

KOREA ELECTRIC POWER CORPORATION

NOTES TO NON-CONSOLIDATED FINANCIAL STATEMENTS

DECEMBER 31, 2007 AND 2006

1. GENERAL

Korea Electric Power Corporation (the “Company” or “KEPCO”) 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. The Company was given the status of a government-invested enterprise on December 31, 1983 following the enactment of the Government-Invested Enterprise Management Basic Act. The Company’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 December 31, 2007, the Government of the Republic of Korea, Korea Development Bank (“KDB”), which is wholly owned by the Korean Government and foreign investors held 21.12%, 29.95% and 27.47%, respectively, of the Company’s shares.

In accordance with the restructuring plan by the Ministry of Commerce, Industry and Energy (MOCIE) on January 21, 1999, the Company spun off its power generation division on April 2, 2001, resulting in the establishment of six power generation subsidiaries. In order to promote the internal competition, the Company organized SBU (Strategy Business Unit) on September 25, 2006 and had been operating it.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The Company maintains its accounting records in Korean Won and prepares statutory non-consolidated financial statements in the Korean language (Hangul) in conformity with the KEPCO Act, Accounting Regulations for Public Enterprise·Associate Government Agency, which have been approved by the Korean Ministry of Finance and Economy and, in the absence of specialized accounting regulations for utility companies, and 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 non-consolidated financial statements are intended solely for use by only those who are informed in Korean accounting principles and practices, KEPCO Act and Accounting Regulations for Public Enterprise & Associate Government Agency.

The accompanying non-consolidated financial statements have been condensed, restructured and translated into English (with certain expanded descriptions) from the Korean language non-consolidated financial statements.

The Company’s 2007 financial statements to be presented to the shareholders’ meeting were approved at the board of director meeting on February 11, 2008.

The accompanying financial statements are stated in Korean Won, the currency of the country in which the Company is incorporated and operates. The translation of Korean Won amounts into U.S. dollar amounts is included solely for the convenience of the readers outside of the Republic of Korea and has been made at the rate of (Won)938.20 to US$1.00 at December 31, 2007, the Base Rate announced by Seoul Money Brokerage Service, Ltd. Such translations should not be construed as representations that the Korean Won amounts could be converted at that or any other rate.

Certain information included in the Korean language non-consolidated financial statements, but not required for a fair presentation of the Company’s financial position, results of operations, cash flows or changes in shareholders’ equity is not presented in the accompanying non-consolidated financial statements

Significant accounting policies followed by the Company in preparing the accompanying non-consolidated financial statements are summarized as follows:

Adoption of Newly Effective Statements of Korea Accounting Standards

The Korea Accounting Standards Board (“KASB”) has published a series of Statements of Korea Accounting Standards (“SKAS”), which replace the existing financial accounting standards, established by the Korean Financial and Supervisory Board. The Company prepared its financial statements as of December 31, 2007 in accordance with Financial Accounting Standards and SKAS in the Republic of Korea.

The Company newly adopted SKAS No. 11-”Discontinuing Operations”, No. 21-”Preparation and Presentation of Financial Statements”, No. 22-”Share-based Payment”, No. 23-”Earning per Share”, No. 24-”Preparation and Presentation of Financial Statements (Financial Industry)” and No. 25-”Consolidation Financial Statements”, effective from January 1, 2007.

Pursuant to adoption of SKAS No. 21, statement of changes in shareholders’ equity was prepared only for the year ended December 31, 2007 in accordance with the transitional provision of the above SKAS. Also, certain amounts and accounts of prior year’s financial statements are reclassified to conform to the current period’s presentation. This reclassification does not affect the net loss and net assets of the prior year.

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. 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 costs 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.

Depreciation is computed by the declining-balance method (straight-line method for buildings and structures) using rates based on the estimated useful lives as follows:

	Estimated useful lives (years)
Buildings	8, 15, 30
Structures	8, 15, 30
Machinery	16
Ships	9
Vehicles	4
Others	4

Construction grants are initially recorded and presented in the accompanying non-consolidated 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.

Major maintenance and repair expenditure that increases the value of assets or increase the estimated useful life of assets are recorded as an increase of the book value, while ordinary expenditure that maintains normal operating condition is recorded as expense incurred.

Tangible assets are evaluated at each balance sheet date to determine whether there is any objective evidence of impairment loss. If future economic benefits can be less than carrying amount and the present value of expected future cash flows is less than the carrying amount, the company considers recognition of an impairment loss. The amount of impairment loss is measured as the difference between the recoverable amount and the carrying amount.

Intangibles Assets

Intangible assets, which consist of computer software, 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 (decline-balance method for other purchased computer software) over a reasonable period, from 4 years to 20 years, based on the nature of the asset.

	Estimated useful lives (years)
Software	5
Industrial right	10
Land right	10
Others	4~20

Due to a significant adverse change in the extent or manner its being used, or a significant decrease in the market price of intangibles asset, if it’s future economic benefits are less than its carrying amount significantly, and the sum of the undiscounted cash flows expected to result from its use and eventual disposition is less than its carrying amount, the company considers recognition of an impairment loss.

Investment Securities Other than those Accounted for Using the Equity Method

Classification of Securities

At acquisition, the Company classifies securities into one of the three categories: trading, held-to-maturity or available-for-sale. Trading securities are those that were acquired principally to generate profits from short-term fluctuations in prices. Held-to-maturity securities are those with fixed and determinable payments and fixed maturity that an enterprise has the positive intent and ability to hold to maturity. Available-for-sale securities are those not classified either as held-to-maturity or trading securities. Trading securities are classified as short-term investment securities, whereas held-to-maturity and available-for-sale securities are classified as long-term investment securities, except for those whose maturity dates or whose likelihood of being disposed of are within one year from the balance sheet date, which are classified as short-term investment securities.

Valuation of Securities

Securities are recognized initially at cost (determined by the moving average method for equity securities and by the specific identification for debt securities), which includes the market value of the consideration given and incidental expenses. If the market price of the consideration given is not available, the market prices of the securities purchased are used as the basis for measurement. If neither the market prices of the consideration given nor those of the acquired securities are available, the acquisition cost is measured at the best estimates of its fair value.

After initial recognition, held-to-maturity securities are valued at amortized cost. The difference between their acquisition costs and face vales (commonly referred to as “discounts” or “premiums” on debt securities) is amortized over the remaining term of the securities by applying the effective interest method and added to or subtracted from the acquisition costs and interest income of the remaining period.

Trading securities are valued at fair value, with unrealized gains or losses included in current operations. Available-for-sale securities are also valued at fair value, with unrealized gains or losses included in accumulated other comprehensive income (loss), until the securities are sold or if the securities are determined to be impaired and the lump-sum cumulative amount of accumulated other comprehensive income (loss) is reflected in current operations. For those securities that are traded in an active market (marketable securities), fair values refer to the quoted market prices, which are measured as the closing price at the balance sheet date. The fair values of non-marketable debt securities are measured at the discounted future cash flows by using the discount rate that appropriately reflects the credit rating of the issuing entity assessed by a publicly reliable independent credit rating agency. If application of such measurement method is not feasible, estimates of the fair values may be made using a reasonable valuation model or quoted market prices of similar debt securities issued by entities conducting similar business in similar industries.

Securities are evaluated at each balance sheet date to determine whether there is any objective evidence of impairment loss. When any such evidence exists, unless there is a clear counter-evidence that recognition of impairment is unnecessary, the Company estimates the recoverable amount of the impaired security and recognizes any impairment loss in current operations. The amount of impairment loss of the held-to-maturity security or non-marketable equity security is measured as the difference between the recoverable amount and the carrying amount.

The recoverable amount of held-to maturity security is the present value of expected future cash flows discounted at the securities’ original effective interest rate. For available-for-sale debt or equity security stated at fair value, the amount of impairment loss to be recognized in the current period is determined by subtracting the amount of impairment loss of debt or equity security already recognized in prior period from the amount of amortized cost in excess of the recoverable amount for debt security or the amount of the acquisition cost in excess of the fair value for equity security. For non-marketable equity securities accounted for at acquisition costs, the impairment loss is equal to the difference between the recoverable amount and the carrying amount.

If the realizable value subsequently recovers, in case of a security stated at fair value, the increase in value is recorded in current operations, up to the amount of the previously recognized impairment loss, while for the security stated at amortized cost or acquisition cost, the increase in value is recorded in current operation, so that its recovered value does not exceed what its amortized cost would be as of the recovery date if there had been no impairment loss.

Reclassification of Securities

When transfers of securities between categories are needed because of changes in an entity’s intention and ability to hold those securities, such transfer is accounted for as follows: trading securities cannot be reclassified into available-for-sale and held-to- maturity securities, and vice versa, except when certain trading securities lose their marketability. Available-for-sale securities and held-to-maturity securities can be reclassified into each other after fair value recognition. When held-to-maturity security is reclassified into available-for-sale security, the difference between the book value and fair value is reported in accumulated other comprehensive income. Whereas, in case available-for-sale security is reclassified into held-to-maturity securities, the difference is reported in accumulated other comprehensive income and amortized over the remaining term of the securities using the effective interest method.

Investment Securities Using the Equity Method

For investments in companies, whether or not publicly held, under the Company’s significant influence, the Company utilizes the equity method of accounting. Significant influence is generally deemed to exist if the Company can exercise influence over the operating and financial policies of an investee. The ability to exercise that influence may be indicated in several ways, such as the Company’s representation on its board of directors, the Company’s participation in its policy making processes, material transactions with the investee, interchange of managerial personnel, or technological dependency. Also, if the Company owns directly or indirectly 20% or more of the voting stock of an investee, the Company generally presumes that the investee is under significant influence. The change in the Company’s share of an investee’s net equity resulting from a change in an investee’s net equity is reflected in current operations, retained earnings, and accumulated other comprehensive income in accordance with the causes of the change which consist of the investee’s net income (loss), changes in retained earnings and changes in capital surplus and accumulated other comprehensive income.

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. The Company does not record its share of losses of an affiliate when such losses would make the Company’s investment in such entity less than zero unless the Company has guaranteed obligations of the investee or is otherwise committed to provide additional financial support.

Any excess in the Company’s acquisition cost over the Company’s share of the net fair value of the investee’s identifiable net assets is considered as goodwill and amortized by the straight-line method over the estimated useful life. The amortization of such goodwill is recorded against the equity income (losses) 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, unrealized gains and losses on transactions with an investee are eliminated to the extent of the Company’s interest in the investee. However, unrealized gains and losses from a down-stream transaction with a subsidiary are eliminated in their entirety.

Assets and liabilities of foreign-based companies accounted for using the equity method are translated at the current rate of exchange at the balance sheet date while profit and loss items in the statement of income are translated at the average rate and the capital account at the historical rate. The translation gains and losses arising from collective translation of the foreign currency financial statements of foreign-based companies are offset and the balance is recognized as accumulated other comprehensive income.

Cash and Cash Equivalents

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

Financial Instruments

Short-term financial instruments are instruments managed by financial institutions which are held for short-term cash management purposes, maturing within one year, including time deposits, installment savings deposits. Long-term financial instruments are financial instruments not included in current assets.

Allowance for Doubtful Accounts

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

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.

Convertible Bonds

When issuing convertible bonds, the values of the conversion rights are recognized separately. Considerations for conversion rights are measured by deducting the present value of ordinary or straight debt securities from the gross proceeds of the convertible bonds received at the date of issuance. The amortization of the premium and conversion right adjustment is recorded as a component of interest expense.

Discount (Premium) on Debentures

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

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 salary rates 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 non-consolidated balance sheets. A portion of the liability is covered by an employee’s severance benefits trusts where the employees have a vested interest in the deposit with the insurance company in trust. The deposit for severance benefits held in trusts is, therefore, reflected in the accompanying non-consolidated balance sheets as a reduction 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 for employees to the National Pension Fund. The amount transferred reduces the retirement and severance benefit amount payable to employees when they leave the Company and is accordingly reflected in the accompanying non-consolidated financial statements as a reduction of the retirement and severance benefit liability. However, due to the new regulation effective April 1999, such transfers to the National Pension Fund are no longer required.

Reserve for Self-Insurance

In accordance with the Accounting Regulations for Public Enterprise Associate Government Agency, the Company provides a self-insurance reserve for loss from accident and liability to third parties that may arise in connection with the Company’s non-insured facilities. The self-insurance reserve is recorded until the amount meets a certain percentage of non-insured buildings and machinery. Payments made to settle applicable claims are charged to this reserve.

Foreign Currency Translation

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 (Won)938.20 to US$1.00, the rate of exchange at December 31, 2007 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 companies accounted for using the equity method 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 are offset and the balance is accumulated as accumulated other comprehensive income.

Derivatives

Derivative instruments are initially recognized at fair value on the date on which a derivative contract is entered into and are subsequently remeasured at their fair value. Changes in the fair value of derivative instruments are recognized immediately in current operations.

Provisions, Contingent Assets and Contingent Liabilities

Provisions are recognized when all of the following are met: (1) an entity has a present obligation as a result of a past event, (2) it is probable that an outflow of resources embodying economic benefits will be required to settle the obligation, and (3) a reliable estimate can be made of the amount of the obligation. Where the effect to the time value of money is material, a provision is recorded at the present value of the expenditures expected to be required to settle the obligation.

Revenue Recognition

The Company recognizes revenue from the sale of electric power based on meter readings made on a monthly basis. Revenue other than sale of electric power 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.

Income Tax

Income tax on income or loss for the period consists of the corporate income tax and resident tax surcharges currently payable, and the changes in deferred income tax assets and liabilities during the period.

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 in which the carrying amount of assets and liabilities will be realized or settled, using tax rates enacted or substantially enacted at the balance sheet date.

Use of Estimates

The preparation of 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.

Prior Period Financial Statements’ Reclassification of Accounts

According to SKAS No.21-”Preparation and presentation of Financial Statements”, the Company restated financial statements as of December 31, 2006, which has no effect on the net assets, income before income tax and net income.

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 (a component of capital surplus) or offset against accumulated deficit by the resolution of the shareholders.

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

Until December 10, 2002 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 received 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 reserve for dividend equalization, which is considered a voluntary reserve, is appropriated by the Company to reduce fluctuation of dividend rates for the purpose of stabilizing the Company’s stock price and credit rating.

Independent Accountant’s Review Report

on Internal Accounting Control System (“IACS”)

English Translation of a Report Originally Issued in Korean

To the Chief Executive Officer of

Korea Electric Power Corporation:

We have reviewed the accompanying Report on the Management’s Assessment of IACS (the “Management’s Report”) of Korea Electric Power Corporation (the “Company”) as of December 31, 2007. The Management’s Report, and the design and operation of IACS are the responsibility of the Company’s management. Our responsibility is to review the Management’s Report and issue a review report based on our procedures. The Company’s management stated in the accompanying Management’s Report that “based on our assessment of the IACS as of December 31, 2007, the Company’s IACS has been appropriately designed and is operating effectively as of December 31, 2007, in all material respects, in accordance with the IACS Framework established by the Korea Listed Companies Association.”

We conducted our review in accordance with the IACS Review Standards established by the Korean Institute of Certified Public Accountants. Those standards require that we plan and perform a review, objective of which is to obtain a lower level of assurance than an audit, of the Management’s Report in all material respects. A review includes obtaining an understanding of a company’s IACS and making inquiries regarding the Management’s Report and, when deemed necessary, performing a limited inspection of underlying documents and other limited procedures.

A company’s IACS represents internal accounting policies and a system to manage and operate such policies to provide reasonable assurance regarding the reliability of financial statements prepared, in accordance with accounting principles generally accepted in the Republic of Korea, for the purpose of preparing and disclosing reliable accounting information. Because of its inherent limitations, IACS may not prevent or detect a material misstatement of the financial statements. Also, projections of any evaluation of effectiveness of IACS to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Based on our review, nothing has come to our attention that causes us to believe that the Management’s Report referred to above is not fairly stated, in all material respects, in accordance with the IACS Framework established by the Korea Listed Companies Association.

Our review is based on the Company’s IACS as of December 31, 2007, and we did not review its IACS subsequent to December 31, 2007. This report has been prepared pursuant to the Acts on External Audit for Stock Companies in the Republic of Korea and may not be appropriate for other purposes or for other users.
