Dec 13, 2024 · Battery Energy Storage Systems (BESS) offer a transformative opportunity to modernize the energy sector. BESS enhances grid stability and facilitates renewable energy
5 days ago · Recently, the Ministry of Industry and Trade has issued Circular No. 09/2025/TT-BCT and Circular No. 12/2025/TT-BCT stipulating the method of electricity generation price
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.
In 2023, EVN PECC3 estimated that the cost for a 2 MWh BESS system was 360–420 USD/kWh, and that the investment would requires electricity prices in Vietnam above 18 UScent/kWh to be profitable – this is twice the current levels. However, BESS costs are declining rapidly.
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.
Sunita Dubey and Hyunjung Lee share how Vietnam is leveraging Battery Energy Storage Systems to stabilize their grid and accelerate the energy transition.
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.
Household BESS installations are typically in the range of 3-20 kWh. As an example, in the USA a 13.5 kWh Tesla Powerwall costs $11 500 with installation. These systems enhance self-consumption by storing surplus solar energy generated during the day for use at night or during cloudy periods.
The global residential solar storage and inverter market is experiencing rapid expansion, with demand increasing by over 300% in the past three years. Home energy storage solutions now account for approximately 35% of all new residential solar installations worldwide. North America leads with 38% market share, driven by homeowner energy independence goals and federal tax credits that reduce total system costs by 26-30%. Europe follows with 32% market share, where standardized home storage designs have cut installation timelines by 55% compared to custom solutions. Asia-Pacific represents the fastest-growing region at 45% CAGR, with manufacturing innovations reducing system prices by 18% annually. Emerging markets are adopting residential storage for backup power and energy cost reduction, with typical payback periods of 4-7 years. Modern home installations now feature integrated systems with 10-30kWh capacity at costs below $700/kWh for complete residential energy solutions.
Technological advancements are dramatically improving home solar storage and inverter performance while reducing costs. Next-generation battery management systems maintain optimal performance with 40% less energy loss, extending battery lifespan to 15+ years. Standardized plug-and-play designs have reduced installation costs from $1,200/kW to $650/kW since 2022. Smart integration features now allow home systems to operate as virtual power plants, increasing homeowner savings by 35% through time-of-use optimization and grid services. Safety innovations including multi-stage protection and thermal management systems have reduced insurance premiums by 25% for solar storage installations. New modular designs enable capacity expansion through simple battery additions at just $600/kWh for incremental storage. These innovations have improved ROI significantly, with residential projects typically achieving payback in 5-8 years depending on local electricity rates and incentive programs. Recent pricing trends show standard home systems (5-10kWh) starting at $8,000 and premium systems (15-20kWh) from $12,000, with financing options available for homeowners.
