On 20 July 2026, EVN said rooftop solar in Hung Yen is being used by businesses and households to secure their own power supply, lower operating costs, and reduce pressure on the power system during high-load periods.
The article says the trend is spreading thanks to communications, guidance, and grid-connection support from the local power unit. From garment factories to households, several examples are presented as showing practical results: lower electricity costs and a more stable power supply for production and daily life.
EVN also cites Hung Yen power staff as saying that most current systems are self-produced and self-consumed, so only a limited amount of electricity is exported to the grid. The article says the power sector buys only about 20% of surplus output, so the impact on the grid is minimal.
At the end, the article says local power units continue to promote efficient electricity use, including switching off unnecessary appliances and making better use of natural daylight during peak hours.
