cement production, the energy cost accounts for a large proportion of the total cost. Because cement enterprises have space resources such as mines or factories, they naturally have the conditions to develop photovoltaic projects, and more and more cement enterprises begin to build photovoltaic projects. Through the construction of photovoltaic power plants, enterprises can use their own vacant land, building roofs and other resources to generate electricity, reduce the cost of purchased electricity, and improve energy efficiency.
In response, Fan Jinji, deputy general manager of Beijing Shengyun Energy Technology Co., Ltd., general manager of energy storage industry and doctor of China University of Science and Technology, pointed out that photovoltaic power generation has strong volatility and uncertainty. When there is plenty of sunshine in the daytime, photovoltaic power generation is abundant, but at night or in rainy days, the power generation will decrease. In order to make full use of the benefits generated by photovoltaic power plants, cement enterprises need to be equipped with energy storage systems.

with China Cement Network. For example, a cement plant in Yingde, Guangdong, has built an 8 MW photovoltaic power station, which can generate about 10 million degrees of electricity a year. After that, the plant was equipped with a 100M Wh energy storage system, which saved 20 million kilowatt-hours of electricity a year, equivalent to an increase of more than 20 million yuan in net profit.
At present, the integration of photovoltaic power generation and energy storage system is the general trend. However, Fan Jinji pointed out that the vast majority of optical storage projects on the market are not real integration of optical storage. These "fake" projects only build two separate systems of photovoltaic and energy storage, photovoltaic power generation is connected to the grid separately, and energy storage system is charged from the grid. The
real photovoltaic storage integration project is a photovoltaic power generation system combining photovoltaic power generation and energy storage. Photovoltaic power generation can not only be directly connected to the grid, but also solve the problem of unstable power generation in photovoltaic power generation through the storage of energy storage system, reduce the pressure of grid-connected photovoltaic power generation, and improve the efficiency of energy utilization. At the same time, combined with the peak and valley power consumption period, the flexibility of charging and discharging of energy storage system is used to reduce the cost of power consumption of enterprises, so as to increase the benefits of photovoltaic power generation and maximize the use of energy.
Fan Jinji introduced that Beijing Shengyun Energy Technology Co., Ltd. (Hereinafter referred to as "Beijing Shengyun") takes word-of-mouth and quality as its business strategy, and provides a new way of income for cement enterprises in the current difficult market of cement industry.
Beijing Shengyun's integrated photovoltaic and storage solution can reduce the cost pressure of cement enterprises without bearing the project investment cost; after the project is put into operation, the benefits generated by photovoltaic power generation can be fully utilized, which not only creates additional economic benefits for enterprises, but also has important significance for promoting the optimization of energy structure and environmental protection.
Beijing Shengyun focuses on new energy storage technology research and product development, is an integrated service provider of energy storage equipment, energy storage system integration and energy storage services, and is also a veteran of the new energy industry. Beijing Shengyun will devote itself to increasing investment in technology research and development, promoting innovation in photovoltaic and energy storage technologies, establishing close cooperation with cement enterprises, and providing sustained and reliable support for cement enterprises to reduce costs and increase efficiency.
