Energy Management

LITEON has implemented the ISO 50001 Energy Management System at 10 operating sites to continuously improve energy efficiency and production performance. The energy management system covers electricity, diesel, natural gas, liquefied petroleum gas (LPG), and other energy sources used across operations.

LITEON regularly reviews energy consumption, identifies significant energy uses, and applies Energy Performance Indicators (EnPIs) to monitor and analyze energy-use patterns in relation to production activities. Energy efficiency improvements are implemented through equipment upgrades, process optimization, operational management, and energy management system enhancements. The Company also provides energy-saving education and training to strengthen employees’ awareness and participation.

In 2025, LITEON implemented 33 energy efficiency projects, achieving total electricity savings of 8.97 million kWh and reducing greenhouse gas emissions by approximately 4,304 metric tons CO2e. Key initiatives included improving compressed air systems, optimizing exhaust ventilation and HVAC controls, recovering waste heat, integrating production lines with utility systems, and deploying equipment with power recovery functions.

LITEON continues to increase renewable energy utilization through energy conservation initiatives, rooftop solar power generation systems, and the procurement of international renewable electricity certificates. The Company also actively engages renewable energy suppliers and enters into long-term green power purchase agreements to support low-carbon manufacturing and reduce operational carbon emissions.

In 2025, LITEON’s renewable energy consumption, including electricity associated with bundled and unbundled renewable electricity certificates, reached 138,778 MWh, accounting for 39.6% of total electricity consumption and exceeding the annual renewable energy target of 38.3%. The primary renewable energy sources were solar and wind power. LITEON remains committed to achieving 100% renewable electricity use by 2040.

Direct and Indirect Energy Consumption

Purchased electricity represents the largest share of energy consumption across LITEON’s operations and manufacturing sites, followed by purchased steam. Indirect energy consumption accounts for more than 97% of LITEON’s total energy use.

Direct energy consumption includes fossil fuels such as diesel, gasoline, natural gas, liquefied petroleum gas (LPG), and acetylene. These energy sources are primarily used for emergency generators, forklifts, company vehicles, cafeterias, and dormitory boilers.

In 2025, total energy consumption at LITEON’s major operating sites reached 1,274,380 GJ, an increase of 139,707 GJ, or 12%, compared with 2024. Energy intensity was 8.10 GJ per NTD million of revenue, representing a 10.5% decrease from 2024. This improvement was mainly attributable to enhanced energy management, increased automation, and higher production value.
