Energy Conservation Practices and Project Achievements

Since 2007, Aikte has remained focused on the recovery and hierarchical utilization of residual heat, with particular success in the complex extraction and efficient reuse of medium- and low-grade thermal energy. As of 2024, Aikte has completed 205 energy-saving projects across eight provinces in China, including 198 engineering-based projects where clients independently enjoy the energy-saving benefits, and 7 performance-sharing projects under the Contract Energy Management (CEM) model.

The recovered heat sources include typical forms such as mine ventilation exhaust, equipment heat dissipation, and underground geothermal water. These technologies have been comprehensively applied across mining office buildings, residential zones, public facilities, workshops, shaft insulation, and underground thermal hazard mitigation. Through these efforts, Aikte has established a wide-ranging implementation network and rich experience in mining-sector deployment.

Below is a table summarizing the energy savings from seven CEM projects implemented between 2014 and 2023. All data has been verified through strict calculations, third-party certifications, or media reports. Specific data is as follows:

Notes:
1. List of Projects:

(1) Beisu Coal Mine Water Heating EPC Project

(2) Juncheng Mine Comprehensive Energy Retrofit and New Energy Utilization Project

(3) Gaojiapu Mine Integrated Energy Utilization Phase II BOT Project

(4) Yangcun Coal Mine “Clean Energy Utilization” EPC Project

(5) Zhaolou Coal Mine Centrifugal Air Compressor Energy Efficiency Upgrade Project

(6) Jining No.3 Coal Mine Centrifugal Air Compressor Waste Heat Recovery Project

(7) Yangcun Coal Mine “Clean Energy Utilization Phase II Project”

2. Aikte’s "Average Energy Sharing Ratio": This reflects the average annual share ratio based on contractual agreements for profit sharing, actual operational durations, and any delayed benefit collections. Since the share ratios vary by project and may overlap in collection periods, an annual average of shared energy savings across all active projects is used for estimation.

3. Remaining 198 Projects: These are engineering construction projects solely implemented by Aikte, where the client purchases the system outright and independently benefits from the energy savings. These projects have not been submitted for third-party certification or formal project confirmation filings, but engineering documentation is available upon request.

4. Cumulative Energy Savings Estimate: The 7 CEM projects have collectively saved 264,055.69 tons of standard coal over 10 years, averaging 3,772 tons per project per year. Assuming a 20-year operational lifespan across all 205 projects, the estimated total energy savings could reach approximately 15.46 million tons of standard coal. (This is an estimated figure for reference only and not legally binding.)

5. Coal Transport Equivalent (for visualization purposes): Based on the standard Chinese railcar load of 60 tons per carriage and converting 1 ton of raw coal into 4400 kcal/kg standard coal for thermal power plants (assuming 100% efficiency), the equivalent of 24.6 million tons of coal saved would require approximately 410,000 train carriages to transport.
