We provide Advanced Solution for
Energy and Environment
As the global energy transition accelerates, Vietnam is also speeding up efforts to expand renewable energy and strengthen energy security. But can increasing energy production alone resolve the country’s power challenges? Due to the intermittent nature of renewable energy, a solution for stabilizing the grid is essential.
In this context, Energy Storage Systems (ESS) are emerging as a core solution. ESS offers strategic value by managing peak demand, stabilizing the grid, and enabling electricity trading and carbon reduction. As such, ESS is expected to play a central role in Vietnam’s energy transition.
However, for the ESS industry to fully take off, not only technological advancements but also policy support and clear regulatory frameworks must be established. In response, the Vietnamese government amended the Electricity Law in 2024 to specifically promote the development of renewable and new energy sources, while expanding incentives and R&D support for appropriate technologies in solar and wind energy. These changes are expected to mark a major turning point in Vietnam’s energy market.
In this issue, we examine the growth potential and driving forces behind Vietnam’s ESS market, explore the technological and policy-related challenges it faces, and consider how a sustainable energy ecosystem can be built around ESS.
1. Creating Energy Value Through ESS
(1) The Current State and Growth Drivers of Vietnam's ESS Market
Currently, demand for ESS in Vietnam is concentrated around industrial zones, but it is gradually expanding to commercial and public sectors. Enterprises are especially drawn to ESS for its benefits in managing peak loads, reducing blackout risks, and cutting energy costs.
In line with this trend, the government is improving the ESS investment environment through initiatives such as the Direct Power Purchase Agreement (DPPA) and the 2024 Electricity Law revision.
Looking ahead, legal and institutional frameworks will allow businesses equipped with ESS to sell surplus electricity in the power market or convert reduced carbon emissions into carbon credits for profit. These developments will shift the role of ESS from a simple storage tool to a core asset in energy monetization, and the ESS market in Vietnam is expected to grow steadily.
(2) Bigtorage’s ESS Capabilities and Market Expansion
In Vietnam’s rapidly growing ESS industry, the most critical competitive advantage lies not just in product supply but in proven on-site experience and system integration capabilities.
Bigtorage has already deployed small-scale ESS and EMS (Energy Management Systems) across a wide range of applications in Korea, including EV charging infrastructure, commercial buildings, and cold chain logistics. Based on this accumulated expertise, the company offers high-quality, integrated energy solutions.
This field-based approach translates directly into a competitive edge in the Vietnamese market. Rather than merely supplying products, Bigtorage is fully prepared to deliver differentiated solutions tailored to local energy conditions and climate requirements, while ensuring operational stability.
Through pilot projects in collaboration with global partners, Bigtorage has proven the reliability and scalability of its solutions across diverse scenarios, including demand response, solar integration, and EV charging.
As Vietnam expands its power trading system and decentralized energy infrastructure, Bigtorage’s PMS (Power Management System) and EMS integration technologies serve as powerful tools for lowering market entry barriers. The company is increasingly seen as a strategic contributor to Vietnam’s energy transition.
(3) The Future of ESS in Power Trading and Carbon Markets
ESS will no longer function as a passive storage device but will play an active role in power markets. Models where stored electricity is sold via P2P trading platforms or where renewable-powered ESS output is converted into carbon credits are already being tested in Europe and South Korea—and Vietnam is moving in the same direction.
In particular, models that quantify carbon reductions based on renewable generation and ESS operational data, and convert them into tradable credits, are emerging as new revenue streams in global markets. These approaches link electricity and carbon markets, thereby greatly enhancing the asset value of ESS.
Conclusion
ESS is evolving beyond a simple energy storage system into a multi-dimensional infrastructure that contributes to grid stability, participates in energy trading, and supports carbon reduction markets.
The Vietnamese government’s regulatory improvements and market liberalization efforts will accelerate the expansion of the ESS industry. Only companies with strong technical foundations and proven experience will be able to achieve sustainable growth in this changing landscape.
Bigtorage is well-positioned to lead this transformation, leveraging its validated technology and scalable platform capabilities, both in Korea and internationally.
With its integrated PMS and EMS solutions—capable of connecting power trading and carbon markets—Bigtorage is set to become one of Vietnam’s most reliable strategic partners in implementing the National Power Development Plan (PDP8) and achieving carbon neutrality.
