In light of our earlier analysis of Decree 135/2024, we have further observations regarding the Decree's lack of clarity. This post is written by Le Thanh Nhat.

Firstly, the Decree lacks a clear definition of “self-generation and self-consumption rooftop solar power” (Self-Consumption RSP). This is crucial as only surplus power from Self-Consumption RSP systems may be sold to EVN, Vietnam's national electricity provider. Unfortunately, Decree 135/2024 only offers the rather ambiguous definitions for “self-generation and self-consumption power” and “rooftop solar power” (which are arguably the two ‘components’ of Self-Consumption RSP) separately, without clarifying their integration.

On 22 October 2024, the Government of Vietnam issued Decree 135/2024 on mechanisms and policies incentivising the development of “self-generation and self-consumption rooftop solar power” (Self-Consumption RSP). Unfortunately, there is still a great deal of ambiguity in the provisions of Decree 135/2024 that might create unnecessary confusion in applying and administering the implementation of Decree 135/2024. Please see our discussion of a few ambiguous provisions of Decree 135/2024 below.

1)       Potential risk from Decree 135/2024’s scope of application – Decree 135/2024 is said to only govern Self-Consumption RSP [systems] that are installed on the roof of construction works that were invested and constructed in strict compliance with law, including regulations on investment, construction, land, environment, safety, firefighting and fire prevention. As such, any noncompliance of the underlying building may cause the rooftop solar system to not be recognised as a Self-Consumption RSP system and therefore cannot enjoy the incentives policies under Decree 135/2024. It is unclear (i) whether mitigated noncompliance in the past (before the Self-Consumption RSP system is installed) would cause the building to be considered not “invested and constructed in strict compliance with law” and therefore prevents the installation of Self-Consumption RSP system on said building, and (i) whether noncompliance that arises after the Self-Consumption RSP system is installed and operated would affect the applicability of Decree 135/2024 to such system and what the outcome would be.

There have been numerous discussions about the new direct power purchase mechanisms (DPPA) introduced under Decree 80/2024 our own briefing note. In this post, we focus on issues which are unclear under Decree 80/2024 and require more clarification. Terms defined in our briefing note will have the same meaning when used herein.  These issues are:

• Decree 80/2024 introduces the concept of “Authorised Electricity Retailer in Zones” (Đơn vị bán lẻ điện tại các mô hình khu, cụm được ủy quyền). However, it is not clear who will verify and determine whether an electricity retailer will qualify as an Authorised Electricity Retailer in Zones. Decree 80/2024 does not make clear if the parties to the DPPA mechanism can verify the qualification of an Authorised Electricity Retailer in Zones or will require a third party (even the authority) to do so.

• To purchase power via a DPPA mechanism, a customer is required to consume an average 200,000 kWh per month. If a Consumer consumes less than 200,000 kWh per month then the DPPA relating to such Consumer may have to be terminated. However, it is not clear if the 200,000 kWh threshold includes the amount of power purchased from (1) both EVN and the RE Generator or (2) EVN only. In other words, it is not clear Decree 80/2024 requires a Consumer to purchase at least 200,000 kWh from EVN. This interpretation seems not logical but not impossible.

Decree 80/2024 outlining mechanisms for direct power purchase agreement (DPPA) between renewable energy generators and large electricity consumers (Decree 80/2024) was issued by Vietnamese Government and became effective 3 July 2024. This Decree is considered as a significant policy that aims to promote the development of renewable energy in Vietnam and enhance the competitiveness of Vietnam’s retail electricity market.

This briefing note discusses the significant highlights of DPPA mechanism to be applicable to renewable power developers, including rooftop solar power developers in Vietnam as introduced by Decree 80/2024. This post is written by Nguyen Thi Kim Anh and Ha Thanh Phuc and edited by Nguyen Quang Vu.
