In June 2025, Northern and Central Vietnam are experiencing a prolonged heatwave with daily highs of 37–40°C, and some areas surpassing 41°C. This extreme weather is driving a surge in electricity demand, particularly during peak midday and evening hours. According to Vietnam Electricity (EVN). . Hanoi, Vietnam (latitude: 21. 8516) is a suitable location for solar PV installations due to its consistent sunlight exposure throughout the year. The average daily energy production per kW of installed solar capacity varies by season, with 5. 97 kWh/day. . Vietnamese authorities are looking to retroactively revise purchase prices for 173 solar and wind projects, reducing revenues by 25% to 46%, risking bankruptcies across the renewable energy sector, and jeopardizing investor confidence needed to meet the government's 2030 targets of 73 gigawatts. . Vietnam has undergone one of the largest solar booms in Asia. The country's updated Power Development Plan 8 will continue this trajectory, with solar making up most of the. . Vietnam's power sector has been expanding alongside its economy—at USD223. 9 billion in 2017—one of the 20 fastest growing in the world with year-over-year growth rates ranging from above 5 percent per year to 7. 1 percent from 2013 through year-end 2018.
