According to Electricity of Vietnam (EVN), the list includes Lai Cau, Trung Son, Dong Nai 2, Huong Son, Tri An, Ialy, Song Ba Ha, Xekaman 1, Dakr Tih and Se San hydropower reservoirs.
Meanwhile, 21 hydropower reservoirs have a remaining capacity of less than 20 percent, including Son La, Tuyen Quang and Thac Ba. Sixteen other reservoirs have water levels below the minimum operating level for the inter-reservoir operation process.
Tri An hydropower Reservoir in the southern province of Dong Nai has dried out amid the ongoing heat. People can even drive their motorbikes or cars through the dry bed sections. It is also easy to see dead fish in the dried sections.

EVN reported that water inflow to 12 major hydropower reservoirs in the north has been extremely low.
Between April and May, the water amount flowing to reservoirs accounted for around half of the figure of many previous years. The rate was merely 20 percent in some reservoirs, resulting in severe water shortages for electricity production.
Meanwhile, electricity demand has spiked due to the prolonged heat. On May 6, the country’s total electricity consumption was measured at 43,000 MW, the highest since early this year and up 9.12 percent on-year.
The northern region would face more scorching hot days from now to the end of July.
