Energy "greener" helps add "new" to the economy of the old industrial city
Climbing to the roof of the factory building of Gezhouba Yicheng Cement Company of China and overlooking the factory, what you see is a new "light" scene-rows of photovoltaic panels are neatly arranged on the roof, standing towards the sun.
"We have used the roof of the factory to install more than 9000 photovoltaic panels, with an installed capacity of 4.95 MW. Not only can we use it spontaneously, but the remaining electricity can also be connected to the Internet." Lu Jianxin, deputy director of the production management department of China Energy Construction Gezhouba Yicheng Cement Company, said that the photovoltaic power generation projects in the plant provide an average of 4.6442 million kilowatt-hours of green electricity every year, save 1310 tons of standard coal every year, reduce soot emissions by 14.64 tons and sulfur dioxide emissions by 37.29 tons.

Lu Jianxin said that the "green" in the factory area does not stop there. On the basis of photovoltaic power generation, the company also makes full use of cement kiln low-temperature waste heat power generation, lithium battery energy storage power stations, etc. to build a green microgrid, and carries out energy-saving and carbon-reduction transformation on the production line., achieving that the proportion of green renewable energy consumption in the factory area exceeds 40%, and the average annual energy cost has been reduced by 0.07 yuan/kWh.
China Energy Construction Gezhouba Yicheng Cement Company is located in Yicheng City, Xiangyang City, Hubei Province. It is a large-scale cement production enterprise. In the past, coal was used as the main fuel. The carbon quota could not meet the normal production of the enterprise, and the difference could only be purchased in the carbon market. In recent years, with the transformation of energy use methods, the proportion of "green electricity" in enterprises has continued to increase. Last year, enterprises had a carbon quota surplus of 23,000 tons. Enterprises are also constantly innovating on the production side, such as cement kiln collaborative disposal of domestic waste production lines, as well as various green and environmentally friendly cement products.
Xiangyang, located in northern Hubei, was once an important base for "third-line construction". In recent years, driven by the "double carbon" goal, this old industrial city has used the rich "scenery" resources in northern Hubei to promote the transformation of the energy sector and enter the fast lane of green and low-carbon development.
Data from State Grid Xiangyang Power Supply Company shows that as of the end of August 2024, the installed capacity of wind and solar power in Xiangyang City reached 5.2832 million kilowatts, accounting for 47.54% of the total installed power generation in Xiangyang City. "Not only that, in order to improve local new energy utilization and power supply reliability, Hubei has also launched the construction of a provincial-level cross-city northern Hubei (Xiangyang, Suizhou) new power system pioneer area to promote the in-situ balance of new energy in Xiangyang and other northern Hubei regions." Yang Hui, chief engineer of State Grid Xiangyang Power Supply Company, said that with the further improvement of power grid regulation capabilities, the application scope of "green power" is accelerating in the local area.

"Since the factory adopted clean energy at the end of 2022, the utilization rate of green electricity has continued to increase. Preliminary estimates have reduced carbon dioxide emissions by approximately 6400 tons." Wang Hu, head of engineering technology of Camel Group Xiangyang Battery Co., Ltd., said that using green electricity to produce supporting parts and components products further enhances the company's competitiveness in the downstream green industrial chain. Currently, the company is continuing to promote energy conservation and carbon reduction through equipment updates and upgrades, control system optimization, etc., and is stepping up the construction of new energy and low-carbon industrial parks to create intelligent green factories.

Energy pursues "green", promoting the continuous increase in the "green" content of energy used by enterprises, retaining a clean background for high-quality economic development and injecting new impetus. "Old industries are embarking on a 'new' path, and new industries are more 'quality'." said Wang Guangning, deputy director of the Xiangyang City Development and Reform Commission.
The Foundry Branch of Dongfeng Motor Co., Ltd. shut down the old factory area and invested 920 million yuan to build a new generation of green casting intelligent factory. The photovoltaic panels laid on the top of the workshop have an average annual power generation of 11.25 million kilowatt-hours; Huazhong Pharmaceutical Co., Ltd. actively promotes The construction of 5G Pharmaceutical and Chemical Smart Park, relying on the Internet of Things, has reduced enterprise energy consumption by 10% and production costs by 10%; Hubei Huadian Xiangyang Power Generation Co., Ltd. carried out energy-saving transformation on the second-phase unit, saving 20 grams of standard coal for every kilowatt hour of electricity generation under design conditions...
"Since the beginning of this year, the city has implemented a total of 34 energy-saving and carbon-reduction technological transformation projects, reducing carbon emissions by more than 100,000 tons." Wang Guangning said that in the future, Xiangyang will continue to use green transformation in the energy sector to drive the green and low-carbon transformation of the industrial structure, improve energy efficiency, and help the coordinated development of energy with economy, society and environment.
