LoRa wireless communication technology realizes multi-site energy dispatching and creates a benchmark for energy storage in the building materials industry
I. Project background: The cement industry ushered in an energy storage revolution
As a typical high-energy-consuming industry, China's cement industry is accelerating the green transformation under the "dual carbon" goal. Recently, a large cement group in Hunan put into operation a 4.2MW/9.03MWh industrial and commercial energy storage system (ESS), becoming the country's first 110kV anti-reverse flow energy storage project for cement plants. The project successfully solved the problem of multi-site coordinated dispatching through the innovative application of LoRa wireless communication technology, and provided a replicable "source-grid-load-storage" integrated solution for the building materials industry.
II. Technological breakthrough: analysis of three major innovations
1. 110kV anti-backflow system design
The project adopts a grid-level anti-backflow protection device to ensure the stable operation of the 110kV main grid in the plant area, while achieving precise coordination between the energy storage system and production equipment to avoid the impact of reverse power transmission on the grid.
2. LoRa wireless communication networking technology
Innovative application of long-distance and low-power LoRa technology to build a wireless communication network within the 3.5 square kilometers of the plant:
Communication distance extended to 5 kilometers, covering all 12 process sites
Power consumption reduced by 60%, annual operation and maintenance cost savings of more than 200,000 yuan
Data transmission reliability reaches 99.99%, supporting real-time energy management
3. Whole-plant energy scheduling optimization algorithm
The AI algorithm is used to optimize the energy consumption of the entire process of "crushing-grinding-calcination":
✅ Energy storage charging during valley power periods, and discharge during peak power periods to supply production lines
✅ Dynamically adjust the operating sequence of heavy-duty equipment such as ball mills
✅ Comprehensive electricity costs reduced by 31.7%, annual electricity bills saved by more than 5 million yuan
III. Economic benefits: Industry benchmark with a 4-year payback period
Indicator Data Industry comparative advantages
Investment scale 32 million yuan 18% lower than traditional solutions
Annual cost savings 5.28 million yuan Peak-valley price difference utilization rate is 92%
Investment payback period is 4.1 years, which is shorter than the industry average of 5.3 years
CO₂ emission reduction is 6,280 tons/year, which is equivalent to planting 340,000 trees
The project has been selected as a typical case of energy storage application in the industrial field of the Ministry of Industry and Information Technology of the People's Republic of China. Its technical combination of "anti-backflow + wireless communication + intelligent scheduling" provides a quantifiable transformation path for the building materials industry.
IV. Industry enlightenment: building materials energy storage has entered the scale stage
According to data from the China Building Materials Federation, the potential market size of energy storage in the national cement industry exceeds 120 billion yuan. This project verifies three major trends:
High-voltage direct connection technology has become the standard for large-scale industrial energy storage
Wireless communication networking reduces the deployment cost of complex scenarios
Process coupling algorithm releases the potential for deep peak regulation
At present, cement companies in Anhui, Guangdong and other places have started the construction of similar projects. It is expected that the installed capacity of energy storage in the building materials industry will exceed 2GW/4.2GWh in 2025.
