Vietnam’s Ministry of Industry and Trade (MOIT) has introduced Circular 62/2025/TT-BCT, the nation’s first pricing framework for standalone, grid-connected battery energy storage systems (BESS) with capacities of 10MW or higher connected to the 110kV national grid. Effective January 26, 2026, this regulation aims to incentivize investment in energy storage, crucial for integrating intermittent renewable energy sources and bolstering grid stability, but its practical implementation remains a key uncertainty for project viability.
The Bottom Line
- Circular 62 establishes a regulated price bracket for BESS, capped at a 12% internal rate of return (IRR), providing a baseline for investor expectations.
- Although a significant step forward, the framework excludes BESS integrated with renewables or owned by state-owned power corporations, limiting its immediate scope.
- Successful market rollout hinges on clear implementation of annual price reviews and dispatch planning by the National Power System and Market Operator (NSMO).
Navigating Vietnam’s Evolving Energy Landscape
Vietnam’s energy sector is undergoing a rapid transformation, driven by increasing electricity demand and a commitment to renewable energy targets. The country aims to achieve 50% renewable energy in its power mix by 2050, according to the National Power Development Plan VIII (PDP8). Reuters reports that this transition necessitates substantial investment in energy storage to address the inherent intermittency of solar and wind power. Circular 62 is a direct response to this require, providing a regulatory foundation for standalone BESS projects.
Decoding the Pricing Mechanics
The core of Circular 62 lies in its pricing methodology. The regulation establishes an annual regulated electricity-generation price bracket, ranging from 0 VND/kWh to a maximum price determined by a formula incorporating average fixed price, variable price linked to charging costs, and fixed operation and maintenance expenses. This approach, while complex, aims to provide a transparent and predictable revenue stream for BESS operators. However, the framework’s reliance on annual price reviews introduces a degree of regulatory risk. The 12% IRR cap, while providing a benchmark for acceptable returns, may prove restrictive for projects with higher capital costs or financing challenges.
Beyond the Formula: Implementation Risks and Market Dynamics
The true test of Circular 62 will be its implementation. The NSMO’s role in capacity planning and dispatch is critical. Effective dispatch prioritization and scheduling are essential to ensure BESS projects can reliably generate revenue. Delays or inconsistencies in these processes could significantly undermine project economics. The exclusion of BESS integrated with renewable energy plants – a common deployment model – limits the immediate impact of the regulation. This exclusion is particularly noteworthy given the rapid growth of solar and wind power in Vietnam. **NextEra Energy (NYSE: NEE)**, a major player in US energy storage, has been closely monitoring the Vietnamese market, and analysts at Morgan Stanley suggest that the exclusion of integrated BESS could slow down overall investment in the sector.
“The Vietnamese government’s commitment to energy storage is evident, but the current framework is a first step, not a final solution. The exclusion of integrated BESS projects is a significant limitation, and the success of standalone projects will depend heavily on the NSMO’s ability to effectively manage dispatch and ensure fair pricing.” – Dr. Nguyen Anh Tuan, Senior Energy Analyst, Viet Capital Research.
Comparative Market Analysis: Vietnam vs. Regional Peers
Vietnam’s approach to BESS pricing differs from that of other Southeast Asian nations. In Thailand, for example, the regulatory framework for energy storage is still evolving, with a focus on pilot projects and feed-in tariffs. ASEAN Briefing highlights the challenges of navigating complex permitting processes and securing long-term power purchase agreements (PPAs) in Thailand. Similarly, Indonesia is developing regulations to support energy storage, but progress has been slower due to competing priorities and bureaucratic hurdles. Vietnam’s Circular 62, despite its limitations, represents a more concrete step towards establishing a dedicated regulatory framework for BESS.
Financial Implications and Investor Sentiment
The introduction of Circular 62 has been met with cautious optimism by investors. While the framework provides a degree of clarity, concerns remain regarding the IRR cap and the potential for regulatory interference. **AC Energy Corporation (PSE: ACEN)**, a Philippine-based renewable energy company with investments in Vietnam, has publicly stated that it will carefully evaluate the implications of the regulation before committing to modern BESS projects. The market capitalization of companies involved in energy storage solutions, such as **Fluence Energy (NASDAQ: FLNC)**, could see a slight uptick as investors anticipate increased demand in Vietnam. However, the overall impact on stock prices will depend on the successful implementation of Circular 62 and the broader macroeconomic environment.
| Company | Ticker | Market Cap (USD) | Revenue (2023, USD) | EBITDA (2023, USD) |
|---|---|---|---|---|
| Fluence Energy | FLNC | $2.85B | $1.65B | $238M |
| NextEra Energy | NEE | $152.3B | $27.05B | $9.48B |
| AC Energy Corporation | ACEN | $2.2B | $1.1B | $450M |
The Path Forward: Expanding the Scope and Addressing Implementation Gaps
To unlock the full potential of energy storage in Vietnam, the MOIT should consider expanding the scope of Circular 62 to include BESS integrated with renewable energy plants. This would align the regulation with the country’s broader energy transition goals and attract a wider range of investors. Streamlining the PPA negotiation process and providing clear guidance on dispatch prioritization are crucial steps to address implementation gaps. The government should as well explore mechanisms to incentivize the deployment of advanced storage technologies, such as flow batteries and compressed air energy storage.
“Vietnam has the potential to become a regional leader in energy storage, but realizing this potential requires a comprehensive and forward-looking regulatory framework. Expanding the scope of Circular 62 and addressing implementation gaps are essential to attract investment and accelerate the deployment of BESS projects.” – Le Van Khoa, Partner, Rajah & Tann LCT Lawyers.
Circular 62 represents a significant milestone in Vietnam’s energy storage journey. While challenges remain, the regulation provides a foundation for growth and innovation. The coming months will be critical in determining whether Vietnam can successfully translate policy intent into commercial reality.
