Market Growth Factors

The Vietnamese government has promoted residential battery use as part of its energy policy to promote rapid renewable energy penetration and electricity grid modernization. In addition to providing a special tariff for solar plus storage projects, Vietnam fast-tracks grid connection when demand is high and offers easier licensing and permitting for homeowners and installers. In March 2025, Decree No. 58/2025/ND-CP, which incentivizes renewable projects and battery energy storage connected to the grid, highlights priority for dispatch at peak demand and priorities for developing solar energy technology and wind energy technology.

Solar-plus-storage for homes is the predominant market in Vietnam's energy storage systems sector. In rapidly urbanizing areas where grid connections are limited, households face intermittent peak demand problems, and are incentivized to invest in residential solar-battery systems for backup and cost advantages. Smart energy management systems can optimize the operation of both the energy consumption and grid to obtain the best return on investment and provide grid stability. The relatively high solar irradiation in southern and central Vietnam can develop rooftop solar power generation. Batteries can balance peak solar generation at midday with evening peak demand, and leasing and power purchase agreements lower the up-front costs of solar installations, further advancing adoption of solar batteries.

Low prices of lithium-ion batteries, due to competition from the global battery manufacturing industry, economies of scale from EV production, and new cell chemistry have made them more economical. Lithium iron phosphate cells produced by Vietnamese manufacturers that passed international safety tests have reduced the need for imported components and lower manufacturing costs. The global lithium-ion battery pack price was USD 112 per kWh in 2024, 20% lower than USD 140 per kWh in 2023, and in China fell 30% to USD 80 per kWh, making it cheaper for Vietnamese households and allowing the utilization of better cycle life, thermal management in tropical climates, and compact design.
