Is a large-scale battery energy storage system (Bess) being deployed in Vietnam?

Steps forward have been taken for the first pilot deployment of large-scale battery energy storage system (BESS) technology in Vietnam.

What is the current state of Bess in Vietnam?

The Current State of BESS in Vietnam As of 2024, Vietnam has practically no BESS installed. So far, only private renewable power projects have trialed BESS development, there is nothing at the utility scale. The largest electricity storage project in Vietnam is the Bac Ai Pumped Storage Hydropower Project.

How much does a Bess system cost in Vietnam?

In 2023, EVN PECC3 estimated that the cost for a 2 MWh BESS system was 360–420 USD/kWh, and that the investment would requires electricity prices in Vietnam above 18 UScent/kWh to be profitable – this is twice the current levels. However, BESS costs are declining rapidly.

Why is Bess important in Vietnam's energy transition?

Regulatory Landscape The Vietnamese government has recognized the importance of BESS in the country's energy transition. The revised National Energy Policy includes new incentives for BESS installations, such as tax credits and subsidies, which are aimed at accelerating the adoption of energy storage solutions.

Can Bess be integrated into Vietnam's power grid?

In an effort to facilitate the integration of BESS into Vietnam’s power grid, the Electricity and Renewable Energy Authority (EREA) of the Ministry of Industry and Trade recently hosted a technical workshop in collaboration with GEAPP.

How will Bess work in Vietnam?

The legal framework for BESS in Vietnam is still developing, but it will likely build upon existing energy laws. The Law on Electricity provides the overarching framework for the power sector, while specific regulations will need to be developed for BESS.
