Sunita Dubey and Hyunjung Lee share how Vietnam is leveraging Battery Energy Storage Systems to stabilize their grid and accelerate the energy transition.
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.
At a meeting on Wednesday, the ADB side, represented by Andrew Jeffries, advisor, Energy Transition Mechanism and Partnerships, proposed building a pilot 50MW/50MWh BESS project near Hanoi. A meeting between EVN and ADB to discuss the BESS project, Hanoi, August 14, 2024. Photo courtesy of EVN.
The government anticipates a 10-12% annual surge through 2030 in the nation’s power consumption. This rapidly expanding energy demand presents a significant challenge to Vietnam’s transforming energy landscape, especially considering the urgent need to reduce global emissions and utilise renewable alternatives.
Vietnam is advancing its energy infrastructure towards a greener, more just, and energy-efficient future, simultaneously providing a valuable model inspiring the global drive towards an energy-resilient future.

Chad Iriba 2.5MW/7.776MWh distributed photovoltaic + energy storage project landed in the Iriba region of the Republic of Chad in central Africa, using “photovoltaic + energy storage” integrated design, with a total installed capacity of 2.5 MW, supporting the 7.776 MWh lithium iron phosphate storage system, the goal is to solve the problem of local power shortages, and at the same time enhance the stability of the power grid to consume energy.
