Impact of Cold Weather on Silicon Metal Production and Price

The production of silicon metal in northern regions indeed faces unique challenges during winter, primarily concentrated in energy supply, production operations, logistics and transportation, as well as environmental policies. The table below summarizes these core challenges.

Challenge Categories

Specific Manifestations

⚡ Energy Supply Pressure

South Enters Dry Season:

Reduced hydropower generation in water-dependent southern provinces like Yunnan and Sichuan leads to higher electricity prices, causing a significant drop in operating rates for silicon plants.

During extreme weather like cold waves, the power grid is also under strain, leading to unstable supply

🏭 Production Challenges

Equipment Insulation: Some enterprises are required to perform "rotating insulation" during high electricity price periods, directly impacting effective production time.

Especially in the Northeast, temperatures often drop to -20 to -30°C, causing materials like silicon mud to freeze easily, making drying more difficult and costly.

🚚 Logistics Bottlenecks

Transportation Disruptions: Heavy snowfall may lead to temporary highway closures, severely affecting the transportation of raw materials and finished products.

•

Poor road conditions and higher risks in winter keep shipping costs high.

🌱 Environmental Policy Constraints

During the heating season, environmental policies are stricter, and many plants have to cut production to meet emission targets.
