6 FAQs about [Vietnam PV inverter grid change requirements]

Can Vietnam achieve 12 GW of solar power by 2030?

To meet the country’s target of having 12 GW of solar power capacity installed by 2030, the Government of Vietnam should consider a deployment strategy that builds experience, lowers costs, and maximizes economic benefits.

Does EVN comply with Vietnam's solar fit regulations?

EVN’s rating aligns with Vietnam’s sovereign rating. The PPA template that accompanies Vietnam’s solar FIT regulations does not follow international standards, in that it contains imprecisions with regard to monthly payments, termination clauses, and curtailment.

Can a solar PV system be installed in Vietnam?

“PCs can strengthen the PPA terms to more bankable terms enabling low-cost long-term financing for industrial consumers.” There is currently no specific legal framework for installation of storage systems for solar projects in Vietnam.

Can grid-connected PV inverters improve utility grid stability?

Grid-connected PV inverters have traditionally been thought as active power sources with an emphasis on maximizing power extraction from the PV modules. While maximizing power transfer remains a top priority, utility grid stability is now widely acknowledged to benefit from several auxiliary services that grid-connected PV inverters may offer.

Why is ERAV proposing changes to the Vietnamese grid code?

To reflect the fact that this will cause substantial changes to the performance characteristics of the future Vietnamese power system, ERAV has proposed amendments to the Vietnamese Grid Code. These changes are considered necessary to ensure secure system operation of the future Vietnamese power system.

Are rooftop solar PV systems a viable alternative to HCMC and Da Nang?

With nearly 30% of the roofs in HCMC and Da Nang capable of installing rooftop solar energy systems effectively (World Bank study), Rooftop solar PV systems provide a viable alternative to address these challenges in these two cities.
