Dak Pru 1 hydropower project is built on Dak Pru stream – (class I branch of Po Ko river originating from Ngok Peng-dia mountain range in Dak Glei district, Kon Tum province with the average elevation of the basin from 700m – 1700m).

Dak Pru 1 hydropower project is about 85 km northwest of Kon Tum city, 6.5 km from Dak Glei town. The project is about 8.0km from Ho Chi Minh Road. The project has a relatively convenient traffic infrastructure when the dam is located right next to the inter-commune road of Dak Glei district.

Dak Pru 1 hydropower project is built in the form of BOO (investment, business and ownership), operates and sells electricity to Electricity of Vietnam (EVN), which is a grade III construction project according to classification. granted in TCXDVN 285-2002.

Dak Pru 1 hydroelectric project has a weir which is a concrete gravity dam about 14m high on the rock foundation, with an installed capacity of 7MW, including items with the following main parameters:

– The dam route has a total length of 70.0m along the dam crest, in which the spillway is 32.5m wide (including 2 pin posts and 2 side posts, each pier is 2.5m thick), arranged in the river bed, Next to the spillway of the river bed is the left bank weir and the right bank.

– The energy route includes the following items: Water intake; steel pressure pipe with diameter D1800 with a length of 1.3km;

– The path-type hydropower plant is located on the right bank of Dak Pru stream with the main parameters:

– The outlet channel of the plant with a length of 86m, a width of 6.0m is responsible for ensuring the continuity of the flow from the water chamber after passing the turbine into the Dak Pru stream in a stable mode;

– Other items include: Operation manager; Operational transport system, 22kV power transmission line 8km long.

Implementation progress of the project: Started in the fourth quarter of 2017, completed in the fourth quarter of 2018

Total investment value of the project: 215 billion VND

After completion of Dak Pru 1 hydropower project in the fourth quarter of 2018, it will provide electricity for the load demand of Dak Glei district and part of Kon Tum province through the national grid with a capacity of 7MW and daily electricity output. about 30.2 million kWh per year to meet the increasing demand for electricity today.

To Buong hydropower project is located on To Buong stream in the area flowing through the territory of Chieng Luong, Loong Phieng and Tu Nang communes of Yen Chau district, Son La province.

To Buong stream is a branch on the right bank of Sap Viet stream, with the main stream flowing in the direction of Southwest – Northeast. In the area where the dam and the plant is planned to be built, the stream flow has many fast-flowing sections, swirling, high and bumpy waterfalls, which is a place with great potential to exploit hydroelectric energy.

Traffic conditions to the work are quite favorable: The factory location is about 2.5km from National Highway 6, the dam location is about 2km from Provincial Road 103. From the center of Yen Chau district to the project is about 22 km, and from the center of Moc Chau district to the project is about 30 km.

To Buong hydropower project is built in the form of BOO (investment, business and ownership), operates and sells electricity to Electricity of Vietnam (EVN), which is a grade III construction work according to the decentralization. in TCXDVN 285-2002.

To Buong hydroelectric project with a weir is a concrete gravity dam about 8m high on the rock foundation, with a capacity of 8MW, including items with the following main parameters:

– The dam route with a total length of 102m is arranged with an overflow weir on the river bed, the two dam shoulders are the non-spill part of the dam, the sand discharge sluice and the inlet to the canal;

– The energy route includes the following items: Water intake; aqueduct with a total length of 1,568.38m, a non-pressurized water tunnel with a length of 986.0m; pressure tank and steel pressure pipeline (length 687.46m, diameter d = 1.0m);

– The hydropower plant is located on the right bank of To Buong stream, with the main parameters:

– The outlet channel of the plant with a length of 36.8m, a width of 2.0m is responsible for ensuring the continuity of the flow from the water chamber after passing the turbine into To Buong stream in a stable mode;

– Other items include: Operation manager; transportation system; 110kV power distribution station and 110kV single-circuit transmission line with a length of about 2.5km.

Project implementation progress:

– Initial approval schedule: Started construction in the first quarter of 2010 and completed in the second quarter of 2012;

– Adjustment progress: Started in the fourth quarter of 2013, completed in the fourth quarter of 2015.

Total investment value of the project:

– Total initial investment approved: 183,220 billion VND;

– Total adjusted investment: 194,617 billion VND.

To Buong hydropower project, after completion in the fourth quarter of 2015, will combine with existing power sources to supply electricity for the load demand of Yen Chau district through the national power grid with a capacity of 8MW and an output of 8MW. annual electricity is about 36 million kWh to meet the increasing demand for electricity today.

The basic parameters of the Factory:

• Installed capacity: 6MW.
• Annual electricity output: 21.9 million kWh.
• Total investment: 102 billion VND.
