Longyangxia Dam
The dam is composed of its main body and a gravity pier and secondary dam on both its left and right flank. The dam's service spillway contains two 12 metres (39 ft) wide gates that discharge water into two 260 metres (853 ft) and 280 metres (919 ft) long chutes. Downstream discharges are also controlled by a similar single-chute middle outlet and the lower outlet works.
Photovoltaic power station
In 2013 a solar photovoltaic station was built with a nameplate capacity of 320 MWp (Phase I), covering 9 square kilometres (3.5 sq mi). An additional 530 MWp (Phase II) was completed in 2015, covering further 14 square kilometres (5.4 sq mi), making Longyangxia Dam Solar Park, with 850 MWp capacity, one of the largest photovoltaic power stations in the world.
The solar power station is integrated with the hydroelectric power station. The park is coupled to one of the hydroelectric turbines, which automatically regulate the output to balance the variable generation from solar before dispatching power to the grid. This limits the problems connected to variable solar generation while helping to conserve water.
