At the end of 2021, the calcium carbide market was affected by the "power rationing and production limit" caused by the 

shortage of electricity and the dual control policy of energy consumption, the price fluctuated and hit new highs repeatedly. 

Under the background of "carbon peaking and carbon neutrality", the calcium carbide industry, as a high energy-consuming 

industry, is affected by multiple influences that limit the overall supply capacity of calcium carbide. The supply of calcium 

carbide throughout the year was relatively tight, the strengthening of the power curtailment policy, and the demand for high 

profits of downstream PVC made calcium carbide difficult to find at one time and the overall supply was in short supply, 

especially the Energy Bureau of the Department of Industry and Information Technology of the Development and Reform 

Commission of the Inner Mongolia Autonomous Region of the Inner Mongolia Government issued: Submerged arc furnaces 

of 30,000 kVA and below, in principle, will all be withdrawn before the end of 2022; those that meet the conditions can be 

replaced by capacity reduction at a ratio of 1.25:1. For calcium carbide, which is in short supply, the new production situation 

in 2022 has become the focus of the market.
