Under the influence of energy saving and emission reduction plans such as carbon peak and carbon neutralization formulated by the state, the contradiction between power supply and demand has become increasingly prominent, and the price difference between peak and valley of power has been widening. Peak cutting and valley filling and optimizing the way of power consumption have become an inevitable way for industrial enterprises to reduce the cost of power consumption, and more and more industrial enterprises have begun to focus on energy storage systems.
1. Application value
of energy storage technology in cement industry As a high energy-consuming enterprise, cement has a complex power consumption environment, which requires not only stable power consumption quality, but also low power consumption cost. Especially when the power is suddenly cut off in the factory, it may cause different degrees of damage to the key equipment such as motor, fan, rotary kiln, mill and so on, which not only affects the continuous production process, but also causes huge economic losses. Based on the above situation, the application of energy storage power station in cement plant not only solves many practical problems for enterprises, but also brings remarkable economic and social benefits.
1 Energy cost optimization
The cement plant is equipped with an energy storage system, which can charge at low electricity prices and release the stored electricity for production at high electricity prices, thus reducing the cost of electricity expenditure. In recent years, peak electricity price policies have been set up in many places in China, and the economy of installing energy storage in cement enterprises has been significantly enhanced. According to the agent purchase price announced by power grid enterprises in March, the maximum peak-valley price difference is 1.33 yuan per degree, and 14 places exceed 0.7 yuan per degree.
2 Stability
of Energy Supply Cement production requires a continuous and stable energy supply, and any power interruption may lead to production stagnation, resulting in huge losses. The energy storage system can be used as a standby power supply to provide emergency power support for the cement production line to ensure the continuity of production when the power grid fails or the power supply is unstable.
3 Boosting the consumption
of renewable energy With the increasing application of renewable energy in the cement industry, the problems of intermittency and instability have gradually become prominent. Energy storage technology can store the excess electricity generated by renewable energy and release it when needed, improve the utilization rate of renewable energy and reduce the dependence on traditional fossil energy.
In recent years, user-side energy storage subsidy policies have been frequently introduced and continuously increased, mainly focusing on electricity price and market transactions, planning layout and subsidies. According to the statistics of Polaris Energy Storage Network, in 2018-2023, a total of 15 provinces and municipalities explicitly put forward 96 energy storage subsidy policies, including Anhui 6, Beijing 2, Guangdong 32, Henan 2, Jiangsu 13, Inner Mongolia 2, Sichuan 3, Zhejiang 24, Chongqing 6, Qinghai/Shanxi/Shaanxi/Tianjin/Fujian/Hunan; A total of 34 policies explicitly propose energy storage subsidies in 2024.
Second, the head cement enterprises have laid out energy storage
in succession. Under the guidance of the "double carbon" target and the promotion of multiple benefits, the energy storage layout of cement enterprises has become increasingly hot, and almost all the head cement enterprises have taken action.
Taking Hangzhou Shanya Southern Cement as an example, the 15.05 MWh user-side energy storage project invested and operated by Guangdong New Juneng Energy Technology Co., Ltd., a member of the Three Gorges Water Conservancy Group, has created huge economic and environmental benefits.
According to the energy demand and characteristics of South Shanya, Xinju Energy has constructed a three-in-one solution of "stable supply and stable production + cost reduction and efficiency increase + policy value-added". After the implementation of energy storage, the annual electricity expenditure is expected to be reduced by 15%; the transformer utilization rate is increased by 18%; the carbon emission intensity is reduced by 12%, and the carbon emission is reduced by 496.5 tons; and the emergency and response power grid scheme is added to effectively improve the emergency power supply and peak regulation and frequency modulation capacity.
As Ma Bo, general manager of New Juneng, put forward in his speech at the 14th China Cement Industry Summit in 2025, "Energy storage is not only a technical option, but also a strategic asset for cement enterprises to reconstruct their energy competitiveness."
It is understood that since 2023, Xinjuneng and Tianshan Materials under China Building Materials have cooperated in several bases in Jiangsu, Zhejiang, Hunan and Anhui, with more than ten cooperative energy storage projects and installed capacity of about 150 MWh.
Third, with the goal of increasing revenue, "energy storage + electricity sales" two-wheel drive
new giant energy is the core member enterprise of Chongqing Three Gorges Water Conservancy and Electric Power (Group) Co., Ltd. As an important member of the Three Gorges Water Conservancy Group in exploring the new power market, Xinjuneng has the full link service capability of investment, design, construction and operation.
In addition, Xinjuneng also strives to build a "energy storage + electricity sales" service model, through direct supply of green electricity, optimizing power procurement and other ways, to help enterprises build green cement brand, reduce electricity costs, and meet the needs of sustainable development.
As a leading one-stop digital intelligent energy storage operator in China, the new Juneng self-developed virtual power plant platform has real-time monitoring, operation alarm, strategy optimization, data analysis, demand management and other functions, which can provide better investment returns and technical support for energy storage projects through cloud edge collaboration.
When cement meets new energy, it is the right time to break the situation. We believe that with the support of excellent new energy service providers such as Xinjuneng, more and more green cement plants like South Shanya will emerge in the cement industry. We hope that the upstream and downstream industries will work together to promote the cement industry to achieve energy structure optimization and green low-carbon transformation, and contribute to the realization of the "double carbon" goal.
