Energy Management Program

Climate change is an issue of common concern to all mankind. TWM will continue to work towards the goal of controlling temperature rise within 1.5 degrees Celsius, developing climate strategies and moving towards net zero emissions, participating in relevant unions/associations, and advocating organizations in order to comply with the global climate accord of the 'Paris Agreement'. TWM will minimize the footprint of the company and its value chain using the latest IoT and AI technologies, not only reduce the environmental impact but also create a more comfortable and beautiful ecosystem.

TWM commits to a 1% annual electricity reduction from the 2024 baseline. In 2025, we outperformed our goal by saving 24.75 million kWh (5.3%), far exceeding the 4.65 million kWh objective. Looking ahead, we aim for 18% renewable energy and 30% fleet electrification by 2026, increasing to 22% and 50% respectively by 2027, ensuring alignment with our RE100 (2040) and EV100 (2030) commitments.

1. Data Center and Server Room Optimization: Implementing dynamic airflow management, natural cooling systems, and high-efficiency power supply equipment. All server rooms are equipped with LED lighting. These technical enhancements are continuously monitored through ISO 50001 systems to maintain high-standard Power Usage Effectiveness (PUE).
2. Office Resource Efficiency: Offices maximize natural illumination by utilizing transparent glass windows to reduce the demand for artificial lighting. We supplement this with motion-sensing LED lamps that automatically adjust to occupancy levels to prevent energy waste. Regular infrastructure reviews and the promotion of energy-saving behaviors among employees further drive continuous improvements in energy performance. Retail Store Energy Management: Our retail stores undergo rigorous daily maintenance and strategic equipment upgrades to minimize operational carbon footprints. We utilize a comprehensive equipment database to manage assets and prioritize the replacement of legacy lighting with LED fixtures. Furthermore, TWM is systematically phasing out older air conditioning units in favor of advanced energy-efficient inverter models.
3. AI-Driven Base Station Optimization: TWM utilizes AI-driven smart energy-saving technology at base stations to analyze customer traffic behavior and dynamically adjust equipment loads. By introducing diversified smart methods and using big data to identify high-consumption equipment, we successfully saved over 18 million kWh in 2025, significantly reducing the carbon footprint of our mobile network infrastructure.

We track energy performance across 100% of our operations through the ISO 50001 Energy Management System and vehicle monitoring tools. Progress is reviewed every six months by the Environmental Working Group to identify further optimization opportunities.

There are 2 sources of our green energy:

1. Diversified Renewable Energy Portfolio: TWM utilizes diversified green power sources to achieve carbon neutrality. We maintain self-owned renewable energy facilities with a 0.3168 MW capacity for cell tower stations and server rooms. Additionally, we have secured Power Purchase Agreements (PPAs) exceeding 110.37 MW, reaching a total renewable energy consumption of 137.4 million kWh in 2025.
2. Strategic Milestones and RE100 Commitment: We are accelerating our transition toward RE100 by 2040. In 2025, TWM reached an 18.6% renewable energy usage rate. Notably, our Cloud IDC operations achieved 100% green energy usage in 2024, six years ahead of schedule. To ensure continuous growth, we target 18% usage by 2026 and 22% by 2027.

1. AI in RAN: Utilizing offline models to predict traffic and optimize carrier configuration, which saved over 18 million kWh at base stations in 2025

2. Smart Cooling: Our Kaohsiung Qianzhen server room Introduced AI energy-saving solution, to use big data analysis of IT devices loading and cooling load to dynamically adjust the load of chiller and water pumps, reduce about 19.3 MWH power consumption.

Because of the good energy saving efficiency, in the future plans we will introduce step by step to applicable server rooms.

TWM announces Environmental and Energy Policy, as well as relevant environmental regulations, on a regular basis every year. Employees are encouraged to actively participate in energy-saving and carbon-reduction efforts to contribute to the planet. Energy efficiency training is provided on the intranet. Additionally, monthly statistics on office water and electricity consumption, waste generation, and printer usage are shared to promote various energy-saving measures. This initiative aims to raise employees' awareness of energy consumption reduction, encouraging them to start with water conservation, electricity savings, and plastic reduction.

* Non-renewable energy sources include electricity, fuel oil, and natural gas.
