Through the continuous operation and improvement of the energy management system, the Company aims to create sustainable energy use, deliver high-quality products and services, and achieve the GHG emission reduction targets required by customers.
Energy Management Policy
In line with the energy laws and regulations and customer requirements, Ta Ya instills energy awareness among employees, conducts green procurement, and manages targets for continuous improvement. To further maintain sustainable operations and fulfill its responsibilities as a good corporate citizen, Ta Ya promotes all personnel to engage in the energy management system based on risk management, green production, and energy performance management for compliance with regulations and customer requirements, and improved energy efficiency.
Energy Management System
Ta Ya has adopted the ISO 50001 Energy Management System and obtained third-party verification. The system effectiveness is tracked through energy performance evaluation, energy targets and management programs, and internal and external audits. The progress of energy targets and the results of external audits are reviewed at a committee meeting in Q1 of the following year.
Following the ISO50001:2018 international standard, Taya Company has developed an energy manual that outlines its energy management system. This system ensures ongoing compliance with energy regulations while effectively preventing or reducing negative energy impacts to achieve the company's energy policy.
Internal Audit & Third Party Verification
TA YA conducts regular internal audits to verify the effectiveness and adequacy of its energy management system, ensuring compliance with the ISO 50001:2018 international standard. According to the Energy Management Internal Audit Procedure, regular audits are performed annually, with additional unscheduled audits conducted based on customer or government agency requirements.
TA YA’s total energy consumption in 2025 amounted to 139,077 GJ, of which electricity accounted for 98%, diesel 2%, gasoline 0.17%, and liquefied petroleum gas 0.05%. Total energy consumption decreased by 6.5% compared with the previous year, while energy intensity decreased by 16.2%.
The significant decrease in energy intensity was mainly attributable to an 11.5% year-on-year increase in standalone revenue, while energy consumption declined by 6.5%. This indicates that energy consumption has been decoupled from revenue growth, reflecting the effectiveness of TA YA’s energy management efforts.
Energy Targets
TA YA continued to implement energy-saving initiatives in 2025, achieving recognized electricity savings of 1,115,291 kWh and an annual electricity savings rate of 2.79%, successfully meeting the annual electricity savings target.
In terms of renewable energy use, TA YA began purchasing renewable electricity from subsidiary BOYA in 2025, increasing the share of renewable electricity use to 8.7%. However, TA YA did not meet the RE10% target, mainly because the renewable electricity wheeling process took longer than expected and did not commence until November 2025, resulting in insufficient wheeled electricity to meet the full-year target.
Energy Saving Initiatives
TA YA implemented a range of energy-saving initiatives in 2025, including replacing aging wire drawing machines, improving heat dissipation in the air compressor room, replacing air-conditioning systems with energy-efficient models, installing variable-frequency controls at the municipal water booster station, and replacing motors. In 2025, TA YA reported total electricity savings of 1,115,291 kWh, achieving an annual electricity savings rate of 2.79%.
