China’s First Million-Kilowatt Solar-Thermal Project Connects to Grid in Qinghai

The pairing of a 900 MW PV array with a 100 MW molten-salt tower is the detail worth noting: storage-backed concentrated solar is what lets a large solar complex deliver into evening peaks rather than only midday, and the cited peak-shaving and absorption benefits point to that role. This is a grid-integration story more than a generation one, and it lands in a province already dense with renewables, where curtailment is the binding constraint. Whether the CSP share scales beyond a token fraction of such projects is the open question for storage economics.
