Vietnam has more than doubled the amount of surplus rooftop solar power that projects can sell to the grid and widened access to its direct power purchase agreement (DPPA) mechanism, with the aim of improving distributed solar economics and expanding corporate clean energy procurement.
The government raised the rooftop solar export cap from 20% to 50% of total generation, according to a policy update released by state utility Vietnam Electricity (EVN) on June 26.
Until the end of 2030, installations may be allowed to sell more than 50% of their output if the regional grid can safely absorb the additional electricity. Projects in mountain, border and island areas that are not connected to the national grid will not be subject to an export limit.

Vietnam has raised the rooftop solar grid export cap from 20% to 50%, with projects permitted to exceed the threshold through 2030 where grid conditions allow, strengthening the financial case for distributed solar investment.
Decree 243/2026 formally extends DPPA eligibility to large electricity consumers operating data centers, giving the sector greater access to direct renewable power procurement.
EVN has warned that expanding DPPA participation to electricity retailers could shift system costs onto other users, while the Ministry of Industry and Trade is seeking to formalize such access through amendments to the Electricity Law.
