Section 1

METHOD FOR DETERMINING THE PRICE OF RAPID START-UP ANCILLARY SERVICES AND CONTINUOUSLY REQUIRED OPERATIONAL ANCILLARY SERVICES TO ENSURE ELECTRICITY SUPPLY CAPACITYOF POWER PLANTS

Article 4. Method for Determining Fixed Price

1. The fixed price (denoted as "P")_cđ) of the Service Support Unit is determined according to the following formula:

Where:

The Service Support Unit is responsible for determining the expected available capacity of the unit in year N to negotiate and include it in the service support supply contract with Vietnam Electricity Corporation as the basis for determining the fixed price of the Service Support Unit.

2. The planned availability factor () of the Service Support Unit for year N is determined according to the following formula:

Where:

Article 5. Method for Determining Total Fixed Revenue

Fixed revenue year N (R_cđ) of the Service Support Unit is determined according to the following formula:

G_cđVL_SCL(VND) from direct and indirect power plants participating in the electricity market;_OM,N(VND) from direct and indirect power plants participating in the electricity market;_{Depreciation expense}+ G_DC+ N_{N |||}

Where:

1. Total depreciation expense of fixed assets (D_SCL) of the Service Support Unit in year N is determined based on the value of existing fixed assets and those expected to be put into use in year N in accordance with regulations on management, use, and depreciation of fixed assets issued by the Ministry of Finance or authorized agencies. Total depreciation expense is the estimated depreciation value of fixed assets to be accrued in year N at the time when both parties negotiate the pricing plan for the approval of the service support price of the power plant providing service support.

In case there is a difference between the estimated depreciation value of fixed assets in the service support pricing plan for year N-1 and the actual implementation in year N-1, this difference will be considered and adjusted in the depreciation expense in the service support pricing plan for year N.

2. Total fixed operating cost year N (O_OM,N) of the Service Support Unit is determined according to the following formula:

For Service Support Units owning newly commissioned power plants that participate in providing ancillary services and have not yet had financial statements audited by independent auditors, during the first two years, such Service Support Units shall be responsible for establishing, negotiating, and agreeing with Vietnam Electricity Corporation on the total cost of purchased ancillary services for year N.

d) The method for determining other monetary costs (C_{signing and implementing Agreements})

Other monetary costs for year N (C_{signing and implementing Agreements}) shall be determined excluding taxes and fees.

Meal allowances and land rental fees for year N shall be determined according to regulations. Other monetary costs for year N (C_{signing and implementing Agreements}) shall exclude meal allowances and land rental fees based on data from the independent auditor's audit for year, excluding abnormal one-off costs in year, excluding abnormal expenses of year N-2, adjusted annually based on the average Consumer Price Index (CPI) of the three most recent years prior to the pricing establishment date published by the central statistical agency, and supplemented with reasonable anticipated expenses for yearN |||but not yet accounted for or fully accounted for in year N-2.

For Service Support Units owning newly commissioned power plants that participate in providing ancillary services and have not yet had financial statements audited by independent auditors, during the first two years, such Service Support Units shall be responsible for establishing, negotiating, and agreeing with Vietnam Electricity Corporation on other monetary costs for year N.

e) Exchange rate differential costs for year N shall be calculated based on foreign currency loan contracts, actual principal repayment plans for foreign currency loans, and the expected exchange rate payable for year N. In case there is a difference between the projected exchange rate differential in the ancillary service pricing plan for year N-2 and the actual implementation in year N-2, both parties may consider adjusting the exchange rate differential costs in the ancillary service pricing plan for year N.

For Service Support Units owning newly commissioned power plants that participate in providing ancillary services and have not yet had financial statements audited by independent auditors, during the first two years, such Service Support Units shall be responsible for establishing, negotiating, and agreeing with Vietnam Electricity Corporation on exchange rate differential costs for year N.

g) Where material costs, external service purchase costs, and other monetary costs for year N-1 have been audited and settled, both parties may agree to use these figures to calculate corresponding costs for year N.

3. Interest payment costs and fees for borrowing (C_{Depreciation expense}): Based on loan agreements or legally binding documents between the project owner and lending financial institutions or banks.

4. Adjusted fixed revenue (G_DC) of Service Support Units for year N shall be determined based on the difference between the actual availability factor and the planned availability factor in the pricing scheme due to changes in maintenance schedules and downtime for maintenance in year N-2 (excluding shortened downtime required by the system operator to ensure electricity supply efforts).
