This project, developed by Vietnam Electricity (EVN) in collaboration with the Asian Development Bank (ADB), Rocky Mountain Institute (RMI), Global Energy Alliance for People and Planet (GEAPP), and the Vietnam Energy Institute, marks a crucial step towards Vietnam’s target of developing 300MW of energy storage by 2030, as outlined in the latest Eighth Power Development Plan (PDP 8).

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.

Through the “perfect combination” of flywheel and lithium battery energy storage, it combines the advantages of flywheel energy storage with large instantaneous power, millisecond response, multiple charge and discharge times, lithium battery energy storage capacity and high frequency modulation range, and cooperates with thermal power units to assist frequency modulation.

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.

assessed the Grid/PV/Wind hybrid energy system viability to provide electricity in 25 sites of Chad . designed a solar/wind/diesel/batteries for three climatic zones of Chad . investigated the feasibility of solar/wind/diesel/batteries for the supply of energy needs of Amjarass (a town in Chad).
In this study, the hybrid energy systems are proposed for all the regions that are not yet electrified in Chad. The National Electricity Company (NEC) of Chad produces and distributes the electricity only in 7 of the 23 regions of Chad; meaning that 16 are un-electrified.
Access to reliable energy is fundamental for the development of any community. The electricity is produced in Chad solely from thermal plants that use fossil fuels, which are not environmentally friendly. In addition, the electrification rate of Chad is less than 11%.
The renewable energy implementation with hybrid system design can significantly reduce greenhouse gas emissions and increase electricity access rate in Chad. The National Electricity Company generates electricity using only the diesel generators.
For the Chadian government to solve the energy crisis, it can attract investors by exploring such type of feasibility study of options to electrify the isolated areas. The renewable energy implementation with hybrid system design can significantly reduce greenhouse gas emissions and increase electricity access rate in Chad.
It was observed that, the COE of these proposed configurations were between 0.367 and 0.529 US$/kWh, indicating that for some sites, it was less than the production cost of electricity in Chad (0.400 US$/kWh) and therefore profitable.

Home energy storage systems can typically store between 5 kWh to 20 kWh of electricity, depending on the technology and capacity of the storage unit chosen; this capacity translates to providing electricity for several hours to days, enabling homeowners to become less reliant on grid power; important factors influencing storage capacity include battery type, system size, and usage patterns; different technologies, such as lithium-ion, lead-acid, and flow batteries, offer distinct advantages and drawbacks in terms of energy density, lifespan, and cost.
