Prime Minister Pham Minh Chinh has signed and issued Directive No. 10/CT-TTg dated March 30, 2026 on strengthening electricity conservation and promoting rooftop solar power development.

The Directive emphasizes that ensuring safe, stable, and continuous electricity supply for production, business, and daily life is a key and urgent task, decisive for economic growth and national energy security. The year 2026 marks the first year of implementing the 2026–2030 Socio-Economic Development Plan, which targets double-digit growth, placing significant pressure on electricity supply—especially the development of baseload power and domestic clean energy sources. Meanwhile, global energy markets remain volatile and unpredictable, posing risks to national energy security. Without timely, synchronized, and effective solutions, there is a risk of supply–demand imbalance, particularly during the 2026–2028 period.

Therefore, the nationwide implementation of demand-side management and efficient electricity use is essential to reduce peak load, enhance system efficiency, and limit the need for new power investments. At the same time, the development of self-produced, self-consumed rooftop solar power systems combined with appropriate energy storage solutions will supplement on-site generation, improve system flexibility, and strengthen national energy security.
