❓ Frequently asked questions

How is the fixed price of ancillary service providers calculated?

The fixed price of ancillary service providers is determined by the formula: Gcd = (Pkd,i * H) / n, where Pkd,i is the expected available capacity of unit i, H is the planned annual availability factor of the unit, and n is the number of generating units of the provider.

How is the variable price determined?

The variable price () of ancillary service providers when providing ancillary services at the request of Power System Operation Units and Electricity Market is determined by the formula: = (bi,j * Gnl + CvIp,i) / kWh, where bi,j is the refined fuel consumption rate of unit i at level j, Gnl is the fuel price for electricity production, and CvIp,i is the material cost rate for producing 01 kWh of electricity from unit i.

What responsibilities do ancillary service providers have in determining prices?

Ancillary service providers are responsible for developing fuel consumption curves for generating units and material cost rates to negotiate with Vietnam Electricity Corporation, serving as the basis for determining the variable prices of generating units.

What are the procedures for establishing, reviewing, and approving prices for ancillary services?

Before November 1st of year N-1, Vietnam Electricity Corporation establishes and submits to the Electricity Regulatory Authority for review, which is then approved by the Ministry of Industry and Trade. By December 15th of year N-1, the Ministry of Industry and Trade approves the ancillary service prices for year N for units providing rapid start-up reserve, cold start-up reserve, and forced generation to ensure power system security.

What does the model contract for providing ancillary services stipulate?
