Analysis of Off - Grid News Dynamics in Cement Factories

Core Conclusion‌: Off - grid technology in cement factories centers on energy storage, focusing on “cost reduction and efficiency improvement + energy transition”, and presents three major trends of policy - driven, technology iteration, and scenario expansion, becoming a new direction for industry technical transformation.

1. Policy and Market Driven: Energy Storage Becomes a “Must - Have” for Cement Factories

Under the “dual - carbon” goal, the energy structure transformation of the cement industry accelerates, and energy storage becomes a key means for enterprises to respond to power restriction risks, electricity price fluctuations, and decarbonization pressures:

Cost Optimization‌: By arbitraging peak - off - peak electricity price differences, energy storage power stations can save cement factories over 20 million yuan in electricity fees annually (e.g., a cement factory in Guangdong with a 43.2MW/107.3MWh energy storage system saves 21.3 million yuan annually);

Policy Redefinition‌: Many regions provide subsidies for energy storage projects (e.g., Guangdong Province subsidizes the above - mentioned project by 2.7 million yuan annually), further improving the return on investment.

2. Technological and Scenario Innovation: Energy Storage Systems “Custom - Made”

Cement factory energy storage systems continue to break through in technology selection and scenario adaptation:

Technology Path‌: Lithium iron phosphate batteries become mainstream due to their “high energy density and long cycle life” (e.g., a certain cement factory’s 4MW/8MWh energy storage power station uses lithium iron phosphate);

Scenario Integration‌: Energy storage is combined with photovoltaic power generation, green micro - grids, etc., to create integrated energy systems such as “photovoltaic + energy storage” and “micro - grid” (e.g., a certain cement factory’s “cement cabinet + energy storage” cross - border solution, adapting to high - difficulty scenarios).

3. Industry Trend: Energy Storage Becomes a New Trend for Cement Factory Technical Transformation

Currently, cement factory energy storage projects show three features of scaling, intelligence, and cross - border integration:

Scaling‌: The capacity of single - unit energy storage power stations has leaped from “hundred - megawatt level” to “hundred - megawatt - hour level” (e.g., a 43.2MW/107.3MWh energy storage system);

Intelligence‌: Energy storage systems integrate BMS, EMS, PCS, etc., to achieve flexible adjustment of charging and discharging strategies;

Cross - Border Integration‌: Energy storage deeply integrates with cement cabinets, micro - grids, etc., to expand application scenarios (e.g., the “cement cabinet + energy storage” solution by Xingxing Charging).

4. Future Outlook: Energy Storage Helps Cement Factories “Green Transformation”

With the maturation of technology and policy support, cement factory energy storage will extend to directions such as “off - grid + micro - grid” and “energy storage + carbon management”, becoming a core support for the industry’s cost reduction, efficiency improvement, and green transformation.
