Lower Stung Russei Chrum Hydropower Project, Cambodia

The Lower Stung Russei Chrum Hydropower Project consists of an Upper Dam and power station and a Lower Dam and power station, both situated on the Russei Chrum river. The Upper Dam impounds an annual storage reservoir whereas the Lower Dam impounds a small daily storage reservoir.

The Upper Dam is a concrete faced rockfill dam (CFRD) with a maximum height of 124 m. On the right abutment the dam is connected to a gated ogee crest spillway with concrete chute and flip bucket.

From the power intake at the left abutment water is conveyed through the 3.2 km long headrace tunnel to a surface powerhouse with 2 vertical-axis Francis turbines of each 103 MW installed capacity will be installed. The rated net head is 132 m.

The Lower Dam is an RCC gravity dam with gated overflow spillway incorporated at the dam center. The maximum height of the dam is 67.5 m.

The headrace tunnel is located in the left abutment and has a length of approx. 3.15 km. The surface powerhouse is equipped with 2 vertical-axis Francis turbines of each 66 MW capacity. The rated net head is 86 m.

Pöyry has provided Independent Engineer Services for construction monitoring and inspection of the dam during construction for the design, quality control, material and dam's safety.
