Energy Management
AES is a professional lithium-ion battery module manufacturer, and the main energy used is purchased power, followed by the utilization of diesel and gasoline. In 2023, the energy consumption decreased by 28% from the previous year, and the energy intensity increased by 17%. Trend Power (Changshu) has introduced the ISO 50001 energy management system in 2023 and obtained third-party verification.
In the future, it will continue to monitor and develop energy-saving measures. Lighting and ancillary equipment will be changed to low-energy-consuming equipment to reduce energy consumption and achieve energy conservation and carbon reduction.

Usage of Renewable Energy
The Simplo Group is responding to the global transformation to low-carbon energy by installing rooftop solar photovoltaic systems, entering into renewable energy certificates to increase the proportion of renewable energy use. This gradual approach aims to achieve the RE100 target by 2040. In 2023, the group's use of renewable energy accounted for 65% (note). The usage status of various renewable energy sources is explained below:
- Install rooftop solar photovoltaic systems: Since 2022, the main operational sites have installed rooftop solar photovoltaic systems, with a total capacity of 10.8 MW. The cumulative electricity generated amounts to 8,955 MWh, with a total investment of approximately NTD 250 million.
- Signing a Power Purchase Agreement (PPA).
- Purchasing renewable energy certificates: Purchase locally sourced renewable energy certificates such as International Renewable Energy Certificates (I-RECs). Trend Power (Changshu) have purchased 4,500 MWh of IREC (wind power generation) in 2023.
Energy Conservation
AES is not high energy consuming industry, we committed to enhancing the energy utilization efficiency. For the energy saving, include the lighting, air-compression, chiller and other energy saving apply to effectively lower energy consumption.
| Solution | Energy saving measures | Energy saving volume in 2023 (GJ) | Carbon reduction volume in 2023 (ton CO2e) |
| Lighting system and air compression system | 1.Warehouse lighting with infrared light control 2.Replacing office LED tubes with inefficient light decay 3.Replacing high-energy-consuming air compressors |
969 | 133 |
| Chiller system | 1.Cleansed the air-handling unit/cooling tower regularly 2.Replaced with high-efficiency water pumps 3.Lowered the chilling water temperature 4.Turned off central air-conditioners during winters, introduced fresh air to lower temperature 5.Set up backup ice machine |

Water Resource Management
AES does not use water for manufacturing, but mainly for the domestic use of employees in the factory. Water withdrawals and discharge are following local government regulations, and all waste water is piped and discharged into the sewer system designated by the municipal government for treatment. There is no interaction of shared water resources.
The company regularly tracks water consumption, and regularly entrusts testing units to monitor the discharge of water bodies in the factory area, all of which compliance with local discharge standards and have no impact on the local environment.
| Year | 2021 | 2022 | 2023 |
| Water withdrawal (million liters) | 48.45 | 58.24 | 48.57 |
Water Saving Measures
- The discharge water from the pure water treatment equipment was originally discharged directly for treatment, but it was recycled and used for toilet flushing.
- The toilet sink was originally a manual valve, but now it is an automatic sensor outlet valve.
Waste Management
AES has established management procedure to ensure compliance with the regulatory requirements. We insist on a philosophy of “reduction at the source, and converting waste into resources” to reduce waste and convert waste into resources as the basis of our waste management. Waste generated during operations process includes hazardous waste and non-hazardous waste, all of which are managed and qualified local contractors for cleanup. Recyclable and household waste are sorted and then handed over to qualified contractors for cleanup and recycling. Waste management focuses on recycling and reuse. Waste that cannot be recycled is incinerated for energy recovery, and finally, any remaining waste will be disposed of in landfills.
