Vietnam BESS outdoor power supply

Is battery energy storage systems a new wave in Vietnam?

A New Wave in Vietnam’s Energy Sector: Battery Energy Storage Systems (BESS)! Vietnam is at the forefront of a transformative shift towards renewable energy, with Battery Energy Storage Systems (BESS) emerging as a cornerstone technology in ensuring grid stability.

What is Bess & how can it help Vietnam?

Energy Management: BESS can help manage the intermittency of renewable energy sources, ensuring a balanced and stable supply of electricity. Vietnam has 20.1 GW of solar and wind power, and congestion in the electricity transmission grid sometimes lead to waste of electricity.

What is battery energy storage system (BESS)?

Battery Energy Storage Systems (BESS) play a pivotal role in addressing these challenges by minimising the intermittency of renewables, enhancing grid flexibility, and ensuring reliable power supply. In a significant development, Vietnam Electricity (EVN) has secured approval for its first pilot BESS project with a capacity of 50 MW/50MWh.

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.

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 to find a suitable Bess power rating in Vietnam's power system?

In order to find the suitable BESS power rating and placement in Vietnam’s power system for frequency stability improvement, the frequency response is firstly simulated under various values of BESS power ratings. After that, the simulation for the selected BESS’ rating with various placements is conducted.
