Don't Let the Power Grid's “Mood Swings” Eat Into Your Profits

If you operate a manufacturing facility in northern Vietnam or an industrial park in the south, the outlook for electricity in 2026 is grim: industrial electricity consumption has already reached the limit of 72%. With renewable energy accounting for nearly 40% of the mix, the power grid is no longer a stable supplier but a volatile source of risk.

The "spillover" of solar power in the south and power shortages during the dry season in the north mean that every voltage dip could result in production line downtime costing hundreds of thousands of dollars. In early 2026, the issuance of the Prime Minister's Directive No. 1 marked the end of an era: the model of relying on the whims of the weather is dead, and battery energy storage systems (BESS) have officially moved from behind the scenes to the forefront of strategic planning.

The Dual Policy Engines: An In-Depth Analysis of Two-Part Tariffs and DPPAs

The two most critical variables in Vietnam's energy market this year directly determine how factories calculate their costs:

1. Two-Part Tariff: From "Paying by Volume" to "Paying by Capacity"

Under the latest pilot program, Vietnam is transitioning from a single-rate tariff to a "two-part" system. This is not merely a change in billing methodology, but a revolution in financial logic:

• Energy Charge: Corresponds to the actual amount of electricity consumed.
• Capacity Charge: Corresponds to the amount of grid capacity you occupy (transformer rated power).

The Benefits of Energy Storage: In the past, to handle momentary peak loads, you had to apply to EVN for expensive, high-capacity transformers. Now, by using energy storage for demand management, you can discharge the battery during peak hours, thereby reducing the requested transformer capacity and directly eliminating that hefty fixed "capacity fee".

2. DPPA (Direct Power Purchase Agreement): The "Green Ticket" to Breaking the Monopoly

Under Decree 80/2024/ND-CP and subsequent amendments, large-scale consumers can now bypass intermediaries and purchase electricity directly from wind and solar power developers.

• Challenge: Green energy is inherently intermittent. When the sun goes down or the wind stops, your production lines cannot stop.

The Value of Energy Storage: Energy storage serves as the "balancing mechanism" following the implementation of DPPAs. It allows you to store green electricity when prices are low and release it during peak demand or power shortages. This is not only about saving money but also about securing green orders from international giants by meeting RE100 and ESG certification requirements.

Decoding Circular 62: The First Year of "Legalization" for Energy Storage Assets

Circular 62, which took effect on January 26, 2026, marks the starting gun for Vietnam's energy storage market. For the first time, it provides a commercial framework for independent grid-connected energy storage:

• 12% IRR Cap: The government has set a 12% cap on the internal rate of return (IRR). While this cap prevents excessive profits, it establishes the bankability of energy storage—meaning energy storage has transitioned from a "venture capital" investment to a "certainty asset".
• Pricing Transparency: The maximum price is precisely calculated based on fixed costs, variable costs, and operations and maintenance (O&M) costs. This framework provides commercial and industrial users with a clear cost benchmark.

Targeted BESS Solutions: Addressing Regional Challenges of "Surplus in the North, Shortage in the South"

• Southern Factories: The focus is on increasing the rate of self-consumption of solar power to avoid unnecessary "power curtailment" during periods of electricity surplus.
• Northern Factories: The focus is on load shifting and preventing voltage fluctuations. For the precision manufacturing industry such as semiconductor and Electronics, the millisecond-level switching response of BESS serves as the ultimate safeguard for production line assets.

Three Recommendations for Investors in Vietnam's BESS Sector in 2026

As the leading BESS supplier with deep roots in the Vietnamese market, we recommend that decision-makers focus on the following three points:

• Compliance First: Be sure to review the model PPA contract mentioned in Circular 62 to ensure projects are connected to the grid quickly while policy incentives are still in effect.
• Avoid “Tropical Adaptation Issues” : Vietnam's high temperatures and humidity are detrimental to battery lifespan. Liquid cooling technology, combined with high protection ratings, serves as the core hardware foundation for maintaining a 12% IRR target.

• Phased, Lean Approach: First, address the essential need for uninterrupted power supply (UPS), then shorten the payback period by leveraging “peak-off-peak price differentials” and “capacity fee reductions.”

Conclusion

Vietnam's energy storage market has entered its "regulation-driven" 2.0 era. Circular 62 is more than just a document; it is the starting gun for the energy transition. Do you want to continue bearing the "hidden tax" of grid fluctuations, or transform "costs" into "assets" through lean management?

FAQs

Q1: What is the core value of Circular 62 for commercial and industrial (C&I) energy storage investors in Vietnam?

A: The greatest significance of Circular 62 lies in "certainty". Not only does it provide a pricing framework for standalone grid-connected energy storage, but by setting a 12% IRR (internal rate of return) benchmark, it also enhances the "financeability" of energy storage projects. For investors, this means that energy storage is no longer a vague experiment, but a certain asset backed by law and accepted by banks.

Q2: After the implementation of the "two-part tariff”, how can factories profit from energy storage?

A: Under the two-part tariff, factories are required to pay a "capacity charge". The core value of energy storage systems lies in demand management: by discharging during peak usage periods, they reduce the maximum demand declared by the factory to the grid, thereby directly and significantly lowering monthly fixed capacity charges—rather than merely arbitraging electricity price differentials.

Q3: Given Vietnam's extreme climate, which metric should be prioritized when selecting energy storage equipment?

A: Thermal management efficiency and safety ratings. Vietnam's hot and humid environment accelerates battery degradation, directly threatening the 12% IRR target. We strongly recommend selecting liquid cooling technology over air cooling, combined with an IP55 or higher protection rating, to ensure the system maintains optimal efficiency over a 10-year operational lifespan.

Q4: How can energy storage help Vietnamese factories meet the ESG requirements of international buyers such as Apple and Samsung?

A: International giants require their supply chains to achieve RE100 (100% renewable energy). However, solar or wind power obtained through DPPA (Direct Power Purchase Agreements) is intermittent. Energy storage acts as an "energy balancer”, smoothing out renewable energy output and ensuring factories maximize the use of renewable energy during 24/7 production, thereby securing their place in the green supply chain.
