CPI completes massive hybrid solar PV/hydro plant in Western China

A subsidiary of China Power Investment Corp. (CPI, Beijing) has completed 320 MW solar photovoltaic (PV) plant co-located with an existing hydroelectric dam in Qinghai Province, Northwestern China.

Through this design, the 1.28 GW Longyangxia Hydro Power Station will smooth the output of the PV portion of the plant. This is one of the largest PV plants in the world, as well as the largest PV/hydro project to date.

Hydroelectric generation has been used successfully in other regions of the world to balance the variable output of renewable energy sources cheaply on a very large scale. The very high rate of wind penetration on the Danish grid – around a third of electricity demand – is made possible by balancing the variable output with hydroelectric generation in Sweden and Norway.

Yingli, JA Solar supply modules

The plant incorporates 15 MW of Yingli YGE series PV modules as well as JA Solar modules. Construction work on the project began in March 2013, with commissioning in the first week of December 2013.

During its 25 year lifetime, the PV portion of the project is expected to generate 498 gigawatt-hours (GWh) of electricity.
