1. The periodicity of payment for energy sales by client (EVN) to IPP
The IPP and EVN will together read the metering result on a monthly basis on a mutually agreed date to determine the power delivered and received in a month. The IPP will record the result in writing and send it together with the invoice to EVN within 10 working days from the result reading date. The payment deadline for EVN is within 15 working days from the receipt of the IPP’s invoice.
2. Frequency of price adjustment such that payment in VND reflects equivalent USD value
It is not clear in both Decision 11 and Circular 16, but we understand that the adjustment will be made at the time of payment for grid connected projects. For on-grid rooftop projects, the adjustment is made annually. Provision have been included in previous power project documents.
3. Mechanism for price adjustment (e.g. is applicable price adjustment is weighted average of adjustment period such that seller is not exposed to changes to VND/USD exchange rate).
For on-grid projects, the adjustment is made at the time of payment. For on-grid rooftop projects, the adjustment is made annually. It means that the FiT for on-grid rooftop projects remains the same in a year. The FiT for on-grid rooftop projects for the next year will be adjusted based on the announced VND/USD exchange rate on the last working day of the preceding year.
