New regulations open up large-scale BESS market
The revised Power Development Plan VIII (PDP8) has marked an important turning point in Vietnam's energy industry. For the first time, New concentrated solar power projects are required to integrate a battery energy storage system (BESS). with minimal capacity 10% capacity for 2 hours.
This regulation not only ensures grid stability but also Opening up a large-scale BESS market and predictable, providing significant business opportunities for companies that manufacture, invest in and operate containerized BESS systems.
Why does the PDP8 revision require BESS integration?
Stabilizing the grid as the share of renewable energy increases
- Solar power fluctuates with the weather, easily causing excess electricity during off-peak hours and shortages during peak hours.
- BESS allows surplus power to be stored and discharged during peak hours, reducing power curtailment.
Reduce dependence on oil/gas plants (peaker plants)
- BESS provides instantaneous power, reducing the need to operate high-emission sources.
Answer meeting the Net-Zero 2050 target
BESS helps increase the rate of renewable energy use, reducing CO₂ emissions.
Minimum 10% capacity integration required – solid opportunity
According to the revised PDP8, Each new concentrated solar power project must have a BESS of at least 10% capacity for 2 hours.For example, a 200 MW project must have at least 20 MW BESS with enough capacity to operate for 2 hours.
This creates a predictable market demand, helping businesses plan production, invest in equipment and provide services.
Potential business model from solar BESS
1. Providing ancillary services for EVN
- BESS can participate in frequency regulation, power reserve, voltage stabilization.
- According to the Electricity Regulatory Authority of Vietnam (ERAV)
, ancillary services are being researched and expanded to encourage BESS investment [Not verified - no official implementation document yet].
2. Participate in the competitive electricity market
When the competitive electricity market is complete, BESS owners can sell peak-hour electricity and buy off-peak electricity for storage [based on the model applied in the US and Australia].
Technical requirements & standards for BESS containers

The requirement of a minimum 10% BESS integration for new solar power projects in the revised PDP8 is a significant milestone for Vietnam’s energy sector. This regulation not only creates a certain and predictable market demand but also opens up a variety of business models: from providing ancillary services, participating in the competitive power market to leasing BESS.
For BESS container manufacturers, this is an opportunity to expand their scale, meet international standards and participate deeply in the clean energy value chain. However, to seize the opportunity, businesses need to prepare technology, international certification and flexible financial models.
