TREE NEWS update: Unit 3 of Huaneng Changjiang Nuclear Power Phase II, the first Hualong One reactor in the Hainan Free Trade Port, entered commercial operation on September 17. The project in Changjiang Li Autonomous County, Hainan, plans two 1.2-million-kilowatt units; once both operate, they are expected to save over 6.3 million tonnes of standard coal and cut about 11.68 million tonnes of CO2 annually. Unit 4 completed cold testing on September 7 and is slated for commercial operation in August 2027.
Hainan’s First Hualong One Nuclear Unit Enters Commercial Operation
AI take
This matters less as a single reactor milestone than as a template: a Chinese-designed large reactor anchoring an island grid that has no hydro or coal hinterland, inside a free-trade port being positioned for energy-intensive industry. The grid-absorption profile of two 1.2 GW units on Hainan, and whether that capacity is reserved for industrial users or exported, is the open question. Unit 4's 2027 timeline is the next hard checkpoint.
