The 80/2024/ND-CP decree, which came into effect on July 3, 2024, outlines Vietnam's Direct Power Purchase Agreement (DPPA) policy. This policy seeks to encourage investment in renewable energy and decarbonise the country's economy to achieve net zero emissions by 2050. It is a big step towards putting renewable energy at the forefront of a competitive power market.
Vietnam as the solar powerhouse in Southeast Asia
As Vietnam's economy continues its rapid growth, the country faces an unprecedented surge in energy demand to fuel its industrialisation. Capitalising on its excellent natural conditions for solar energy, Vietnam is poised to become a regional leader in renewable energy development. The DPPA policy is expected to drive the projected 3.39% annual growth in the solar industry from 2024 to 2029, solidifying Vietnam's position as a renewable energy hub in Southeast Asia.
Scope of (DPPA) via National Grid:
- Seller: Renewable energy power plant with a capacity of 10 MW or above
- Buyer: Large electricity consumers with a consumption rate of no lower than 200,000 kWh/month
- Voltage Level of Connectors: No lower than 22 kV
- Mini SCADA (Supervisory Control and Data Acquisition): Required for monitoring and control
Scope of DPPA via Private Wire:
- Seller:
- No capacity limit for renewable energy generation companies (RE GENCOs) or power generation project employers.
- Must possess licenses for planning, investment, construction, and power operation.
- Authorised to sell electricity directly to consumers through private wires.
- Buyer:
- Must have a consumption rate of no lower than 200,000 kWh/month.
- Required to prepare and submit a report along with a copy of the DPPA to the local Provincial People’s Committee and notify the local grid company in writing.
Vietnam's Direct Power Purchase Agreement (DPPA) policy offers several significant benefits for companies operating within the country:
Strengthened Sustainability Profile: By engaging in DPPAs, businesses can demonstrate their commitment to environmentally responsible practices and reduce their carbon footprints. This aligns with the increasing global emphasis on corporate social responsibility.
Financial Predictability: DPPAs provide a more stable cost structure for energy procurement. Unlike the volatility associated with traditional fossil fuel prices, renewable energy contracts through DPPAs can offer long-term price certainty, potentially leading to cost savings over time.
Market Differentiation: Companies that adopt renewable energy through DPPAs may gain a competitive advantage. This proactive approach can appeal to environmentally conscious consumers, investors, and partners, potentially opening new business opportunities.
Future-Proofing Operations: As regulations worldwide increasingly focus on reducing carbon emissions, businesses that proactively transition to renewable energy sources via DPPAs are better positioned to comply with future requirements. This strategic move can help companies avoid potential regulatory challenges and associated costs in the future.
By capitalising on these advantages, Vietnam businesses can contribute to the country’s sustainable development goals and enhance their operational efficiency and market position.
The United States has applauded Vietnam’s approval of the DPPA decree highlighting it as a significant milestone in the renewable energy sector. The U.S Agency for International Development (USAID) has provided technical assistance to Vietnam’s Ministry of Industry and Trade since 2017 on the design, development and finalisation of DPPA.
U.S Ambassador to Vietnam Marc Knapper stated “Our comprehensive strategic partnership marks a new era of collaboration between our two nations, and the DPPA is a testament to our deepening ties and shared commitment to sustainable development”
As Vietnam implements its Direct Power Purchase Agreement (DPPA) policy to promote renewable energy, Growatt provides reliable inverter solutions designed for commercial and industrial applications. The MAX 100-150KTL3-X LV/MV series and the WIT 50-100K-HU + APX 129-200kW systems are well-suited to support this initiative.
In 2022, Growatt was awarded the "All Quality Matters" award by TÜV Rheinland for its MAX 125KTL3-X LV inverter and was recognised as the best commercial and industrial (C&I) inverter in the 100-150kW category for its unparalleled performance.
With 10 MPPTs, the MAX 100-150KTL3-X LV/MV is a step ahead of other competitors, allowing solar investors to maximise their solar harvest by optimising two strings per Maximum Power Point Tracker (MPPT), rather than conventional C&I inverters which handle multiple strings with limited MPPTs. This multiple MPPT design enables solar investors to generate higher energy yields from the whole system, allowing them to see returns on their solar investments quickly. Furthermore, it can handle a string current of up to 16A and an MPPT current of up to 32A, making it perfect for high-power modules used in C&I applications. It is the ideal choice for C&I investors who need a high-power inverter perfectly suited to the DPPA policy.
Some of the functions of MAX 100-150KTL3-X LV/MV include:
High Efficiency: With a maximum efficiency of up to 99.00% and European efficiency of 98.50%, the MAX 100-150KTL3-X LV/MV inverter ensures optimal energy yield, maximising returns on investment.
Advanced MPPT Technology: Featuring up to 10 MPPTs, this inverter series allows for precise energy harvesting from solar panels, even under varying conditions.
Hardy Design: Built to withstand harsh environments, the IP66 protection rating ensures durability and reliability in diverse weather conditions.
Flexible Capacity: The series supports a DC/AC ratio of up to 1.5, making it compatible with high-power and bifacial modules, enhancing overall system performance.
Smart Monitoring and Diagnostics: Equipped with intelligent string monitoring and smart I/V scan capabilities, users can easily track performance and diagnose issues remotely.
Safety: The MAX 100-150KTL3-X LV/MV inverter includes optional AFCI protection and Type II surge protection devices (SPDs) on both DC and AC sides, ensuring safe operation.
The WIT 50-100K-HU C&I storage inverter combined with Growatt’s APX commercial battery system is for solar investors looking to increase the power capacity of their solar installations. It is designed with system flexibility in mind, allowing for scalability of up to 300kW. In terms of MPPTs, it features 7 to 10 MPPTs, making it as efficient as the MAX series inverters.
