Wanji Aluminium Smelter Starts Construction in Xinjiang With Green Power Focus

Wanji Aluminium

Wanji aluminium smelter construction has started in China’s Xinjiang region, marking another step in the country’s shift toward larger, more energy-efficient primary aluminium capacity. The 580,000 t/yr project will require total investment of 4.6bn yuan, or about $667 million.

The Wanji aluminium smelter will use Xinjiang’s clean energy resources, including integrated wind and solar power. This gives the project a lower-carbon positioning at a time when electricity source, power cost, and emissions intensity are becoming central to aluminium competitiveness.

Wanji aluminium smelter development also follows China’s capacity replacement policy. The company currently operates a 580,000 t/yr smelter in Luoyang, Henan province, which is scheduled to be demolished by December 2027 after the Xinjiang capacity is completed.

Xinjiang Project Targets High-Efficiency Aluminium Production

The Xinjiang smelter will use 600kA large-scale electrolytic cells, which Wanji described as the world’s most efficient technology. The project will also adopt advanced process systems to reduce energy use and improve operating performance.

Power consumption is expected to be as low as 12,430 kWh/t of aluminium. That level would place the facility among the world’s most energy-efficient aluminium smelting operations.

This matters because aluminium smelting is one of the most electricity-intensive industrial processes. Producers with access to low-cost renewable power and efficient electrolytic cells can gain a structural advantage over older smelters exposed to coal power, higher tariffs, or carbon costs.

Capacity Replacement Supports China’s Aluminium Upgrade Strategy

The project is moving forward in line with Wanji’s capacity replacement plan released in August 2025. China has encouraged aluminium producers to upgrade electrolytic baths and shift more production toward greener energy sources.

The replacement of Wanji’s Luoyang smelter with the Xinjiang facility shows how China is reshaping its aluminium industry. The strategy is not only about adding volume, but replacing older capacity with larger, cleaner, and more power-efficient assets.

Wanji also plans to build the Xinjiang site into a fuller industrial chain, covering alumina through processed aluminium products. This could strengthen value integration and support downstream aluminium fabrication in the region.

The Metalnomist Commentary

Wanji’s Xinjiang project shows how China is combining capacity replacement, renewable power, and high-efficiency smelting technology to strengthen aluminium competitiveness. The key global implication is clear: low-carbon aluminium will increasingly depend on power strategy as much as smelter scale.
