Solar power is promoted as a low-cost source of electricity. However, making it available when the power system needs it most requires pairing it with expensive battery storage systems, increasing generation costs.

The debate over battery storage is becoming central to Vietnam's energy transition as policymakers weigh higher investment costs against long-term grid benefits.

The utility argues that while battery storage raises investment costs, its effectiveness for large-scale solar projects remains insufficiently defined.

Rooftop solar power is showing clear effectiveness amid soaring electricity prices, which explains why thousands of households rushed to install solar systems in April.

Experts warn of a high risk of power shortages as no major power projects have been implemented in the past decade, while over 170 renewable energy projects remain stalled.

Vietnam has launched its first research project on combining solar energy with agriculture, aiming to increase farmers' incomes while accelerating the country's energy transition.

The Ministry of Industry and Trade has proposed that the Prime Minister direct Vietnam Electricity (EVN) to urgently resolve the obstacles and reach agreements with investors involved in wind and solar power projects.

To support an ongoing investigation, the Ministry of Public Security has requested the People's Committees of Ha Tinh and Quang Binh provinces to provide detailed information and documents related to solar power projects in their respective areas.
