(Yicai Global) Oct. 23 -- A subsidiary of utility giant China Huaneng Group has put eight units at the San River Secondary Hydropower Station, Cambodia's largest such plant, into operation.

Huaneng Lancang River Hydropower finished a 72-hour test of unit eight at the facility on Oct. 21 before official starting commercial operations, the firm said in a statement.

Located on the San River in the east of the country, the power station has an installed capacity of 400,000 kilowatts and a designed average annual output of 2 billion kilowatts. The station consists of 8 bulb tubular turbine generator sets with an installed capacity of 50,000 kw each. It will make up more than one-fifth of the total installed capacity in the country and can ease Cambodia's power supply shortage.

Construction of the facility started in late 2013 and the company used a building-operation-transfer approach for its investment, development, and operation. Key electromechanical equipment was imported from China, and the first generator set began commercial operation at the end of last year.

Huaneng Lancang River Hydropower is a large-scale river basin hydropower company that mainly works on the development, operation and integration of water-power resources in the Lancang River Basin and surrounding areas in southwest China. The Lancang River is the source of the Mekong River that flows through many Southeast Asian countries.
