Tiếng ViệtIn 2025, Decree 58/2025/ND-CP on renewable energy officially comes into effect, introducing significant changes for businesses, particularly in the implementation of rooftop solar power. While the new policy creates opportunities for cost savings and incentives, it also demands that enterprises prepare thoroughly to comply with regulations and embrace the green transition trend.
1. A New Legal Framework: Decree 58/2025 Paves the Way for Renewables
On March 3, 2025, the Government issued Decree 58/2025/ND-CP, providing detailed guidance on several articles of the 2024 Law on Electricity concerning the development of renewable and new energy. This Decree reaffirms the concept of “rooftop solar power” and the right to self-produce, self-consume, and sell surplus electricity to the national grid, provided grid connection conditions are met.
The incentive policies within Decree 58 are heavily focused on new energy projects (such as green hydrogen and green ammonia), but also include support for solar power projects that are combined with energy storage and grid connection.
2. Key Incentives Businesses Need to Know
- Priority Dispatch for Systems with Storage: Renewable energy projects that include an electrical storage system (battery) and are connected to the national grid will be given priority for dispatch during peak hours.
- Support for Research & Domestic Technology: The State encourages and supports technology development in the solar power sector, from photovoltaic panel manufacturing to power conversion equipment.
- Clear Regulations for Surplus Power: Organizations and individuals owning rooftop solar systems can sell surplus electricity to the grid, with the purchase mechanism being factored into the wholesale and retail electricity pricing plans.
3. What Businesses Must Prepare to Comply with the Policy
- Grid Connection Registration/Notification: Even if the system is primarily for self-consumption, businesses must still notify or register with the provincial Department of Industry and Trade and the local power utility as required.
- Meeting Technical Connection Requirements: The system must ensure electrical safety, comply with technical standards, have a bi-directional meter, and, for large capacities (≥100 kW), must integrate monitoring equipment compatible with the grid dispatch system.
- Operational Data Transparency: Businesses must provide weekly and monthly data on power generation, sunshine hours, and operational performance to support the monitoring and planning of the national grid.
- Financial and Technical Preparation: Enterprises need to prepare a clear financial plan (payback period, O&M costs), select quality-certified equipment, and account for weather factors and future expansion capabilities.
4. Cautions and Implementation Notes
It is important to note that Decree 58/2025 will still require detailed implementing circulars from the Ministry of Industry and Trade (MOIT) and the Ministry of Finance (MOF). The allocation of capacity according to provincial and district-level power plans will also be a decisive factor in whether rooftop solar systems can truly integrate without being “grid-stranded.”
Businesses must closely monitor subsequent guiding documents to avoid errors in procedures, grid connection, or failure to properly realize benefits.
The new policy in Decree 58/2025/ND-CP presents a significant opportunity for businesses wishing to invest in renewable energy, especially rooftop solar. However, to capitalize on it, businesses must prepare technically and financially, adhere to procedures, and monitor detailed guiding documents.
