Chapter III

PRINCIPLES OF ELECTRICITY MARKET OPERATION

Article 10. Limit of offered price

1. The offered price of generating sets in the electricity market is limited from the price floor of quotation to price ceiling of quotation.

2. The price ceiling of quotation of the thermoelectric Units is determined annually and adjusted monthly and calculated based on the following factors:

a) Heat rate of generating set;

b) Performance degradation coefficient as per the operational time of generating set;

c) Price of fuel;

d) Coefficient of auxiliary expenses;

dd) Price varying under electricity sale contract.

3. Price floor of thermoelectric set is 01 dong/kWh.

4. Limit of offered price of generating sets is specified in Article 10 of this Circular.

Article 11. Water value

1. The water value is used for setting the operational plan for the next year, month and week and is the input data to determine the limit of offered price of the generating set in the electricity market.

2. The electricity system and market operating Unit shall calculate and announce the water value as per the electricity market operation schedule specified in Annex 1 of this Circular.

Article 12. Full market price

The full market price for the transaction cycle is calculated by the sum of 02 (two) components as follows:

1. Price of market power

2. Price of market capacity.

Article 13. Price of market power

1. The price of market power is calculated by the electricity system and market operating Unit after the operational time based on the unconstrained scheduling method.

2. The price of market power must not exceed the market price ceiling which is calculated by the electricity system and market operating Unit and approved by the Electricity Regulatory Authority annually.

3. The determination of price of market power is specified in Article 67 and 69 of this Circular.

Article 14. Price of market capacity

1. The price of market capacity for each transaction cycle is calculated by the electricity system and market operating Unit during the operational planning for next year and there is no change in the applied year.

2. The price of market capacity is calculated on the principle of ensuring that the best new power plant recovers its variable and fixed costs sufficiently.

3. The determination of price of market capacity is specified in Article 25 and 26 of this Circular.

Article 15. Electricity sale contract for difference

1. The electricity generating Units directly doing transaction and the single wholesaling Units  are responsible for signing the electricity sale contract for difference under the form issued by the Ministry of Industry and Trade.

2. The yearly contract output is calculated by the electricity system and market operating Unit based on the yearly planned output and the ratio of paid output at the contract price specified in Clause 5 of this Article. The annual planned output is calculated by the electricity system and market operating Unit during the operational planning for next year as stipulated in Clause 2, Article 27 of this Circular.

3. The monthly contract output is determined by the electricity system and market operating Unit during the operational planning for next year based on the allocation of yearly contract output in the months specified in Article 28 of this Circular.

4. The hourly contract output is determined by the electricity system and market operating Unit during the operational planning for next month based on the allocation of monthly contract output at the hours in months specified in Article 37 of this Circular.

5. The Electricity Regulatory Authority shall determine and announce the percentage of paid output at the contract price of the electricity generating Units each year depending on each technology model on the following principles:

a) Ensuring the harmonization of objectives:

- Encouraging the effective competition in the electricity market;

- Stabilizing revenues of the electricity generating Units;

- Stabilizing the average price of electricity generation in accordance with regulation capabilitys on setting the electricity retailing quotation.

b) The percentage of power output paid at the contract price is specified separately for different types of hydro and thermal power. This percentage must not higher than 95% and lower than 60%.

Article 16. Principle of payment in electricity market.

1. The electricity generating Units directly doing transaction is paid at the electricity market price and under the electricity sale contract for difference.

2. The payment at market price is applied only to the electricity generating Units directly doing transaction and is calculated based on the following factors:

a) Price of market power;

b) Price of market capacity;

c) Power output and mobilized capacity.

3. The payment for the electricity generating Units directly doing transaction is done as stipulated in Chapter VI of this Cicular.

4. The electricity generating Units indirectly doing transaction is paid under the provisions in the electricity sale contract.
