Vietnam’s government promulgated Decree No. 243/2026/ND-CP, expanding the direct power purchase agreement (DPPA) framework and lifting the surplus rooftop solar purchase cap from 20% to 50%. According to Watson Farley & Williams and 365energy.vn, the June 2026 update targets industrial parks, data centers, and EV charging infrastructure to accelerate renewable integration.
The Bottom Line
- Regulatory Shift: Decree 243/2026/ND-CP amends previous guidelines under Decree 57 and Decree 58, broadening corporate access to clean energy.
- Capacity Expansion: Surplus self-produced rooftop solar electricity sales to the grid jump from a maximum of 20% to 50%.
- Sector Inclusion: Data centers and electric vehicle charging operators connecting at 22 kV or higher can now participate directly in grid-level DPPA markets.
Decoding Decree 243: Restructuring Vietnam’s Clean Energy Access
Promulgated on June 26, 2026, Decree No. 243/2026/ND-CP directly amends earlier frameworks established by Decree 57/2025/ND-CP and Decree 58/2025/ND-CP.
While the regulation unlocks opportunities for manufacturers and digital infrastructure operators, it imposes strict technical prerequisites. Entities must navigate rigorous metering mandates, grid hosting capacity limits, and localized data collection standards. According to legal analysis from Norton Rose Fulbright and VILAF, certain rooftop solar setups must maintain strict “zero-export” configurations to prevent grid destabilization in capacity-constrained zones.
Expanding the DPPA Participant Pool
The core structural change within Decree 243 lies in its broadened definition of eligible market participants. Under prior rules, the private-wire DPPA framework primarily bridged renewable generators and heavy industrial consumers. Today, the scope accommodates electricity retailers operating within closed economic zones, export processing zones, high-tech parks, and industrial clusters.
This aggregation model enables a licensed industrial park retailer to purchase wholesale renewable power and distribute it across multiple tenant factories. Furthermore, digital infrastructure operators and commercial electric vehicle transport networks have entered the fold. Data centers, EV charging stations, and battery-swapping facilities connecting at voltage levels of 22 kV or higher can now procure clean energy directly from developers or state power corporations.
| Regulatory Parameter | Previous Framework (Decree 57/58) | Revised Framework (Decree 243/2026) |
|---|---|---|
| Rooftop Solar Surplus Cap | Maximum of 20% eligible for sale to the grid. | Maximum of 50% eligible for sale to the grid. |
| Eligible DPPA Consumers | Traditional manufacturing and heavy industrial users. | Expanded to include data centers and EV charging infrastructure. |
| Zone-Level Intermediaries | Excluded from direct contracting structures. | Electricity retailers inside approved industrial zones integrated via aggregation models. |
Grid Integration, Metering, and Zero-Export Mandates
Capital deployment into Vietnam’s renewable sector requires precise alignment with infrastructure realities. Projects operating in constrained distribution networks face mandatory zero-export requirements to protect local transformers from reverse-power overloads.
