6 FAQs about [The rationality of Longyangxia solar power generation]

What is a Longyangxia coupling of PV and hydropower?

Large-scale centralised PV power is still in its infancy, and the Longyangxia coupling of PV and hydropower is the first of its kind and provides a valuable example for future hybrid systems linking variable renewables and hydropower.

How big is Longyangxia PV plant?

The Longyangxia PV plant has a capacity of 320 MW and covers a 9 km2 area. It is connected directly to one of the turbine units by a 330 kV transmission line. As one of the largest solar PV stations in the world, without the balancing power of the Longyangxia hydro turbine, this could pose a serious problem for the stability of the grid.
