Recently, the Department of Industry and Information Technology of Guizhou Province announced the results of energy-saving supervision of cement flat glass enterprises in Guizhou Province in 2025. The last announcement of energy conservation supervision was "the results of the first batch of national industrial energy conservation supervision in 2023" in September 2023. There are few provinces that can fully publicize the results of energy-saving supervision of cement enterprises in the province! Moreover, the first publicity of energy-saving monitoring results "selling" should be said to be a bit ugly, but still dare to publicize, urge enterprises to improve, courage is commendable! Fortunately, just one and a half years later, the energy-saving achievements are very proud. It can be seen that publicizing the results of energy-saving supervision of enterprises has played an important role in strengthening the leading role of energy efficiency benchmarking and benchmarking constraints, encouraging and guiding enterprises in the industry to base themselves on long-term development, and implementing energy-saving and carbon-reducing transformation and upgrading with high standards. In
2023 , there were 71 cement enterprises (excluding grinding stations, the same below) that could be assessed, 31 of which failed to meet the energy efficiency standards, accounting for 43%, 26 of which reached the benchmark level, accounting for 37%, 14 of which reached the benchmark level, accounting for 14%, and 34 of which had backward mechanical and electrical equipment in the production line. Accounting for 42% of the total number of enterprises.
In 2025 , there will be 59 cement enterprises in production that can be assessed, of which 0 enterprises fail to meet the energy efficiency standard, accounting for 0%, 24 enterprises reach the (benchmark level) standard, accounting for 41%, 35 enterprises reach the benchmark level, accounting for 59%, and 11 enterprises have backward mechanical and electrical equipment in the production line, accounting for 16% of the total number of enterprises.
From the above data, it can be concluded that:
1. The energy efficiency of cement enterprises in production (all-round) has been cleared if it fails to reach the benchmark level. In June 2023, the National Development and Reform Commission and other five ministries and commissions issued the requirements of "Energy Efficiency Benchmarking Level and Benchmark Level in Key Industrial Areas (2023 Edition)", that is, by the end of 2025, the energy efficiency transformation will be upgraded to above the benchmark level, and the projects that can not be completed on schedule will be eliminated. In principle, the technical transformation of cement clinker should be completed or eliminated by the end of 2025.
2. The proportion of enterprises reaching the benchmark level is close to 60%. The benchmarking level and benchmark level of energy efficiency in key industrial areas (2023 edition) did not put forward the requirement of reaching the capacity share of benchmarking level, and put forward the stock projects with energy efficiency between benchmarking level and benchmark level, encouraging the application of green low-carbon technology and equipment, guiding enterprises to change as much as possible, to raise as much as possible, and to improve the energy efficiency. Drive the whole industry to increase energy saving and carbon reduction transformation efforts, improve the overall level of energy efficiency. It seems that the proportion of enterprises reaching the benchmark level in Guizhou Province has increased from more than 10% to nearly 60%, which should be mentioned as much as possible.
3. The proportion of enterprises with the problem of updating backward mechanical and electrical equipment has also dropped significantly, from 42% to 16%, and 11 enterprises have the problem of updating backward mechanical and electrical equipment. In January 2024, the National Development and Reform Commission and other six departments issued the Advanced Energy Efficiency Level, Energy Conservation Level and Access Level of Key Energy-using Products and Equipment (2024 Edition). For industries with saturated production capacity, the energy efficiency of major energy-using products and equipment should reach the advanced level in principle. Departments in charge of energy conservation, industry and information technology at all levels should strengthen energy conservation supervision, urge enterprises to strengthen energy efficiency management of products and equipment, and eliminate old and backward energy-using products and equipment in accordance with the law and regulations. It is expected that in the next energy-saving monitoring results, the problem of updating backward mechanical and electrical equipment will be cleared. The energy efficiency of cement enterprises
in Guizhou Province should be raised as much as possible! Still have potential, keep up the good work! 33 clinker production lines in Guizhou will face elimination in two years
if we do not grasp the technological transformation of energy saving and carbon reduction!
