Zhanjiang Iron and Steel's first distributed photovoltaic project successfully connected to the grid

On December 15, 2021, the photovoltaic power generation (phase I) project of 48.2MW installed capacity of Zhanjiang Iron and Steel Co., Ltd. was successfully connected to the grid and successfully sent out the "first" photovoltaic power on the roof of Zhanjiang Iron and Steel Plant.

Baowu Qingneng, State Power Investment Group Xuwen Wind Power Co., Ltd., as well as representatives of Zhanjiang Iron and Steel functional departments, energy project team and project participants jointly witnessed the moment of grid connection.

In recent years, Zhanjiang Iron and Steel has adhered to the new development concept and achieved high-quality development by leaps and bounds in the process of pursuing extreme efficiency, ultimate cost, ultimate quality and extreme environmental protection. Zhanjiang Iron and Steel, as the "dream factory" of Baowu, China, low-carbon metallurgy, energy saving and emission reduction, green development are imperative. To this end, Zhanjiang Iron and Steel has made great efforts to explore the construction of hydrogen-based shaft furnace green metallurgical project, but also actively layout clean energy such as photovoltaic power generation. Baowu Qingneng and State Power Investment Group Xuwen Wind Power Co., Ltd. adopted the contract energy management project mode for investment and construction.

Photovoltaic plate

The Zhanjiang Iron and Steel Photovoltaic Power Generation (Phase I) project installs photovoltaic modules on the housing surface of the steel plant. Using the roofs of wide factory buildings such as 4200mm thick plate, 2250mm hot rolling, 1550mm cold rolling, 2030mm cold rolling, railway product depot, etc., a total of 100981 single crystal silicon photovoltaic panels are installed, with a total area of 412500 square meters and a total installed capacity of 48.2MW. The average annual power generation of 47.55 million kWh, is equivalent to saving 15700 tons of standard coal every year. It can reduce carbon dioxide emissions by 46900 tons every year, providing a continuous supply of green electricity for Zhanjiang Iron and Steel.

The construction of Zhanjiang Iron and Steel Photovoltaic Power Generation (Phase I) project has made full preparations. According to the situation of the roof of the plant, the three parties have made detailed designs on the load-bearing structure, installation mode, construction, operation and maintenance, etc., to make reasonable and efficient use of the idle space on the roof to ensure the efficiency of power generation. Since the formal start of the project on September 15, 2021, after on-site test, equipment installation test, reverse power transmission and grid connection, the project and construction team have overcome the influence of high temperature and epidemic situation, worked together to build a solid safety line and create a high-quality project. work together to ensure that the safety, quality and progress of the project are fully controlled. Zhanjiang Iron and Steel will continue to tap the potential of green power generation and start the second phase of photovoltaic power generation project to further improve green power generation.

Zhanjiang Iron and Steel will unswervingly follow the development path of ecological priority, green and low carbon, follow China's Baowu "double carbon" action plan, actively build hydrogen-based shaft furnaces and other green metallurgical projects, and vigorously promote the development of clean energy industries such as green electricity and green hydrogen. we will increase the proportion of renewable energy and contribute Zhangang to China's Baowu carbon peak carbon neutralization goal.
