Officials at the Liujiaxia Hydroelectric power plant in Gansu province in north-west China reported in early April that the volume of water in the plant's reservoir was only 2.6Bm3, or less than half its total capacity, according to the Xinhua news agency.
The plant, located on the upper reaches of the Yellow river, has an installed capacity of 1MkW, and begun generating electricity in 1969. It plans to generate 3BkWh of electricity this year, 1.5BkWh less than the average annual production over the past few years.
