What does Vietnam's Solar Policy update mean for energy storage?

Vietnam’s solar policy update highlights growing role of energy storage. (Photo: iStock) Vietnam’s Ministry of Industry and Trade (MOIT) has announced a new round of feed-in tariffs (FIT) for solar power, introducing location-based pricing and, for the first time, incorporating energy storage systems.

How much does a solar project cost in Vietnam?

Overall, projects with storage receive higher FIT rates. Previously, Vietnam’s FiTs were relatively low. In January 2023, the top rate was NT$1.49/kWh for ground-mounted solar and NT$1.89/kWh for floating solar, with no regional or storage-based distinctions.

What are the conditions for solar storage in Vietnam?

Conditions for systems with storage include a minimum storage capacity of 10% of the solar plant’s installed capacity, a charge/discharge time of 2 hours, and at least 5% of total generation used for charging the storage system. Overall, projects with storage receive higher FIT rates. Previously, Vietnam’s FiTs were relatively low.

What is the new tariff structure for solar projects in Vietnam?

Under the updated tariff structure, solar projects are now divided into ground-mounted and floating categories, and segmented further by region—North, Central, and South Vietnam. Tariffs are calibrated based on solar resource availability, infrastructure costs, and local electricity demand, with higher rates awarded to projects that integrate ESS.

What are the FIT rates for solar systems?

The tariff breakdown is as follows: Conditions for systems with storage include a minimum storage capacity of 10% of the solar plant’s installed capacity, a charge/discharge time of 2 hours, and at least 5% of total generation used for charging the storage system. Overall, projects with storage receive higher FIT rates.

What is the capacity of a solar power plant?

Capacity: Minimum 10% of the installed capacity of the solar power plant. - Storage/discharge duration: 2 hours. - Charging power output ratio: 5% of the total output of the solar power plant./.
