Chinese state-owned company Huanghe Hydropower Development has completed the construction of a 2.2 GW solar plant in northwest China, in the desert area of Qinghai province.
According to the manufacturer Sungrow, which supplied the inverters for the project, the photovoltaic plant was built in five phases. In total, RMB 15.04 billion (approximately US$ 2.2 billion) was invested.
The plant was built with monocrystalline bifacial modules and 900 MW of Sungrow SG250HX 1,500 V string inverters.
According to the Chinese state-owned company, Sungrow provided the highly integrated 250 MWh energy storage system, with a low-voltage design coupled to AC (alternating current), which can increase transformer utilization, ensuring a lower system cost.
Construction of the plant began in November 2019 and was completed in September this year. The storage system was implemented in four months, from May to September. The facility will sell power to the local grid at a price of RMB 0.34/kWh.
The complex is connected to an ultra-high voltage power line that China's State Grid Corp is building to connect the far northwestern parts of the country to the more densely populated eastern provinces.
