How is solar energy regulated in Vietnam?Vietnam’s solar power sector is governed by a number of key regulations and policies aimed at promoting the development of renewable energy while managing the challenges associated with rapid growth.
Is Vietnam ready for a competitive bidding mechanism for solar energy?Vietnam is now developing a competitive bidding mechanism for solar energy to improve grid efficiency, promote competition, and ensure a stable energy supply, but it’s currently in the works and hasn’t been implemented yet. As such, Vietnam has been in a transition phase since the end of the FiT policy.
What is the solar energy potential of Vietnam?In terms of the solar energy potential, Vietnam is endowed with unique solar resources. The total technical potential of photovoltaic power generation is high as 1,646GW, of which 1,569GW is land-based photovoltaic and 77GW is water-based photovoltaic.
How do private solar power plants work in Vietnam?Previously, owners of private solar power plants, whether rooftop or large-scale, could only sell electricity to the grid through conventional power purchase agreements (PPAs), with no option for direct sales to consumers. In Vietnam, there are two types of DPPAs: private-wire DPPAs and on-grid DPPAs.
How has the FIT program impacted solar power development in Vietnam?The FiT program has been a major driver of solar power development in Vietnam, offering a tariff of 9.35 cents per kilowatt-hour (kWh) for projects completed by June 2019. This program led to a surge in solar capacity, reaching 4.46 gigawatts of new installations.
How much solar power does Vietnam have in 2025?As of 2025, Vietnam boasts an installed solar capacity of around 16 GW, a dramatic increase from approximately 4 MW in 2015. This growth trajectory has made Vietnam one of Southeast Asia’s leading solar energy marke
