Yalong River Hydropower Development, a Chinese state-owned hydropower developer, kicked off the construction of a 1-GW solar power station in Sichuan province, southwestern China.

Upon completion, the station will be connected to an operational 3-GW hydropower facility on the Yalong River through an existing 220 KV transmission line and a new 500 KV line, making the complex the world's largest integrated solar-hydropower station in the world.

With a total investment of 5.3 billion ($791 million), the solar station will be built on a plateau at an altitude of 4,000-4,6000km, also making it one of highest power stations in the world. The soar plant will feature more than 2 million solar panels and over 5,000 inverters.

Estimated to be able to generate 2 TWh of power each year, the innovative combination is more significant to be complementary in power generation. Hydropower compensates for the instability of solar power during the night, while turning to solar power can help save water in the long run.

The construction of the solar plant will be completed by the end of 2023, the developer said.

As the exclusive developer of energy infrastructure on the Yalong River basin, the company plans to deploy 80 GW of renewable energy capacity in the area, including 40 GW of wind and solar and 10 GW of pumped-hydro storage.
