From the beginning of 2023 until now, the hydrology of Ham Thuan hydropower reservoir has been unfavorable when the water level at the beginning of the year is 4,9m lower than the normal water level rise, corresponding to a water shortage of 23% compared to the useful capacity. In order to ensure the water supply for agricultural production in the downstream areas of the Ham Thuan and Da Mi hydroelectric reservoirs in the dry season of 2023, at the beginning of the year, DDD Company actively worked with Duc Linh and Tanh Linh districts, the Department of Agriculture and Rural Development (DARD) of Binh Thuan province to agree on a water supply plan for agricultural production and local people's lives. Besides, the Company has actively coordinated with the National Load Dispatch Center in mobilizing power units to meet the local water demand.
The useful capacity of Ham Thuan lake on May 17, 5 is 2023 million m .3
In order to ensure water supply for agricultural production during the peak period of the dry season and the remaining time of the dry season in 2023, on May 17, 5, DHD Company actively worked with the Department of Agriculture and Rural Development and the Department of Agriculture and Rural Development. Binh Thuan Irrigation Department and Binh Thuan Irrigation Works Exploitation One Member Company Limited evaluated the results of water supply in the Winter-Spring season 2023 - 2022 and agreed on the water supply plan for the Summer-Autumn crop in 2023.
According to the results of the local assessment, in the first 04 months of 2023, DHD Company has fully met the water demand in the downstream area. The parties have agreed on a water supply plan for the last months of the dry season and the remaining time of the dry season in 2023. The water supply plan is agreed on the basis of the current water capacity of the reservoir with the forecasted discharge to the reservoir. Ham Thuan in the remaining months is equal to 50% of the average flow of many years and based on the water use demand in the downstream districts of Tanh Linh, Duc Linh at the peak production period of the summer-autumn crop in 2023 in the current situation. hot weather, severe drought.
From the downstream water supply plan in the last months of the dry season, DHD Company will coordinate with the National Load Dispatch Center to operate the Ham Thuan - Da Mi generating sets to ensure the downstream water supply flow as planned, and at the same time coordinate closely with the districts of Tanh Linh, Duc Linh and the Binh Thuan Irrigation Works Exploitation One Member Company Limited to update the hydrological situation, and adjust the daily rainfall in the downstream basin to ensure the efficient operation of the downstream basin and the Duc Linh basin. until the drought ends.
By May 17, 5, the water level of Ham Thuan lake was 2023 m, 581 m from the dead water level.
As of May 17, 5, the water level of Ham Thuan lake is at an elevation of 2023 m, 581 m from the dead water level, corresponding to the remaining useful capacity of 6 million m69.3. Information from the National Center for Hydro-meteorological Forecasting said that in the coming time, the weather will continue to experience extreme changes with little rain, and the flow to the lakes is lower than the average for many years. Therefore, the Company will face difficulties in supplying water for production and daily life in the downstream areas of Tanh Linh and Duc Linh districts, Binh Thuan province.
According to hydro-meteorological forecast information, the weather will become more and more extreme. It is likely that from May to July 5 will be the peak of heat, so the water demand of the downstream will increase, the load will increase, the power system will face many difficulties in providing electricity. DHD Company is trying to implement synchronous solutions to both ensure water supply for downstream and fulfill production tasks assigned by Vietnam Electricity and Power Generation Corporation 7.
