Rooftop solar power helps strengthen electricity self-sufficiency in Northern Vietnam

Rising electricity demand

In the context of rapidly increasing electricity demand in northern Vietnam driven by the development of industrial parks, data centers, the electronics and semiconductor industries, and many large-scale economic projects, rooftop solar power combined with energy storage systems is being seen as one of the important solutions to supplement local power sources, reduce pressure on the national grid, and strengthen regional energy security.

According to the Northern Power Corporation (EVNNPC), Northern Vietnam is expected to continue experiencing high electricity load growth in the coming years. The rapid increase in large electricity consumers both creates momentum for economic growth and raises requirements for the development of distributed power sources and the efficient use of clean energy.

Mr. Nguyen Duc Thien, General Director of EVNNPC, said that along with the strong development of the economy, electricity demand in northern vietnam is increasing rapidly. Many projects in electronics, semiconductors, data centers, high-tech industries, and large industrial parks are being implemented, creating significant pressure on electricity supply assurance.

According to him, in this context, developing self-generated and self-consumed rooftop solar power combined with energy storage systems, along with efficient and economical electricity use, is an important solution to supplement distributed power sources, reduce pressure on the national grid, and improve electricity supply reliability in Northern Vietnam.

EVNNPC leaders noted that rooftop solar power not only helps customers reduce electricity costs but also contributes to lowering investment pressure for new power sources, reducing transmission losses, and promoting the energy transition in line with government orientation.

In particular, when combined with energy storage systems, solar power can achieve higher efficiency in load regulation, improve the ability to supply electricity during peak hours, and support the safe and stable operation of the power system.

Mr. Nguyen Duc Thien, General Director of EVNNPC, emphasized: “Rooftop solar power combined with energy storage systems and efficient electricity use will be one of the key pillars in enhancing energy self-sufficiency and supporting electricity supply in Northern Vietnam in the 2026–2030 period.”

Boosting rooftop solar power development

Implementing Government Decree No. 58/2025 on the development of self-produced and self-consumed rooftop solar power, along with directives from the Prime Minister on efficient and economical electricity use, EVNNPC has deployed multiple solutions including communication campaigns, customer support, and coordination with local authorities to promote this type of power source.

To date, all 17 provinces and cities under EVNNPC’s management have issued plans or directives to develop rooftop solar power and promote electricity saving. Local power companies have also actively coordinated with local authorities, departments, and the business community to guide and support customers in installation.

According to EVNNPC, in 2026 the corporation aims to develop 680 MW of self-produced and self-consumed rooftop solar power. In May 2026 alone, the corporation added 2,376 new customers with a total capacity of 94.04 MW.

In the first five months of 2026, EVNNPC developed 6,416 customers with a total capacity of 298.5 MW, exceeding the set plan. From the implementation of Decree No. 58/2025 to the end of May 2026, EVNNPC has recorded 8,015 customers installing rooftop solar power for self-production and self-consumption with a total capacity of 622.1 MW. Among them, 91 customers have participated in selling excess electricity to the grid with a total capacity of 11.9 MW.

According to the revised National Power Development Plan VIII, the 17 provinces and cities managed by EVNNPC have the potential to develop more than 19,000 MW of rooftop solar power during the 2025–2030 period. This is considered a large potential for developing clean energy sources, mobilizing social resources for energy investment, and contributing to ensuring electricity supply for Northern Vietnam in the coming years.

However, the development of rooftop solar power still faces several challenges, such as relatively high initial investment costs, limited access to preferential financing, less attractive mechanisms for purchasing excess electricity, and the need to further improve procedures related to construction, fire safety, and environmental regulations.

Mr. Phan Tu Luong, Deputy General Director of EVNNPC, said the corporation will continue to improve customer guidance procedures toward simplicity, convenience, and accessibility. At the same time, EVNNPC will strengthen coordination with local authorities, departments, and financial institutions to support households and businesses in accessing capital, technology, and suitable technical solutions.

According to EVNNPC leadership, developing self-produced and self-consumed rooftop solar power combined with energy storage systems and efficient electricity use will remain a key task, contributing to ensuring safe and stable electricity supply, promoting green energy transition, and supporting sustainable socio-economic development in Northern Vietnam.
