Hydroelectric reservoir higher than dead water level, North has enough electricity

According to the report on June 24 of the Department of Industrial Safety Techniques and Environment (DAST), the flow to hydroelectric reservoirs in the Northern and Central Highlands regions increased compared to yesterday; in the North Central, South Central Coast, and Southeast regions, the flow to reservoirs was low, slightly decreasing compared to yesterday.

Water levels in hydroelectric reservoirs increased significantly.

The water level of hydropower reservoirs in the Northern region increased, 5.5m to 20m higher than the dead water level; The North Central, Central Highlands, Southeast, and South Central Coast regions decreased slightly compared to yesterday. The water level of reservoirs in the South Central Coast and Central Highlands regions is within the minimum water level range according to the operating procedures.

The flow and water level at hydroelectric reservoirs in the Northern region have increased, these reservoirs are raising the water level, limiting the mobilization of electricity generation. The Northern region has entered the flood season, the water flow to hydroelectric reservoirs has improved, however, these reservoirs are still limiting the mobilization to prepare for the next heat wave.

The report of the National Power System Dispatch Center (A0) shows that the total electricity output of the system on June 23 reached 834.3 million kWh, of which the Northern electricity output was 384 million kWh, with the largest capacity of 20,613 MW.

For hydropower in the North, with the continued mobilization of Hoa Binh , Lai Chau, Thac Ba, Bac Ha, and Nam Chien 1 hydropower plants, the hydropower output exploited on June 23 reached 61.5 million kWh.

Regarding hydrology, the flow to the reservoirs all increased; the basins of the reservoirs all had rain from 7:00 p.m. on June 23 to 7:00 a.m. this morning, June 24, with rainfall ranging from 30 to 100 mm.

The highest flows to the lakes last night and this morning were as follows: Hoa Binh Lake 1,020 m3/s (at 4:00 a.m. on June 24), Ban Chat Lake 1,390 m3/s (at 9:00 a.m. on June 24), Son La Lake 1,450 m3/s, Tuyen Quang Lake 1,490 m3/s, Lai Chau Lake 721 m3/s. It is estimated that the flows to the lakes will continue to increase for a few hours in the morning of June 24 and will gradually decrease.

The output of coal-fired thermal power plants in the North reached 275.1 million kWh (about 3.5 million kWh higher than June 22) and recorded an increase in output compared to June 22 for some thermal power plants such as Thai Binh 2, Thang Long, Uong Bi 2 expansion, Mong Duong 1. Some of these plants promptly overcame problems and capacity reduction to put them into operation. The coal supply situation for thermal power plants is guaranteed.

According to the Electricity Regulatory Authority, the temperature forecast for the last days of June and the first to mid-July will not be as extreme as the last days of May and early June, so the demand for household electricity is unlikely to skyrocket as in the past.

The average daily load in the North is forecasted to be around 421.7 million kWh. If there is a reasonable operating regime and good implementation, synchronous solutions to ensure electricity supply, the Northern power system will basically meet the load demand.
