Technical FAQs 4

Are battery energy storage systems economically feasible in Vietnam?

However, in Vietnam, there is a widely held industry perception that Battery Energy Storage Systems (BESS) are not economically feasible at this moment, while the country's first pumped storage hydropower (PSH) project Bac Ai with a capacity of 1,200 MW will not be commissioned until 20289.

How much money does Vietnam need to build a grid?

According to PDP8, the total investment required for the development of grid from 2021 to 2030 amounts to $14.9 billion, equivalent to $1.5 billion per year or 0.4% of Vietnam's GDP in 2020 (Table 1). The strained state budget alone may struggle to accommodate such substantial financial requirements.

Does Vietnam have a strong electricity sector?

Vietnam's electricity sector has experienced substantial growth, becoming the second largest in Southeast Asia in terms of installed capacity, behind Indonesia.1The country has witnessed a significant increase in electricity consumption, with an average annual growth rate of 12% between 2000 and 2020.

Does Vietnam have a power shortage?

Vietnams total power demand is expected to grow 10% annually during the period 2021-2024, and power shortages are expected to increase in different regions of the country.
