Energy Management

Energy Management Policy

Upholding the duty as a corporate citizen, we spare no effort to implement environmental and social responsibilities while operating the company and developing technology. Therefore, we established the Energy Management System Promotion Committee in 2016 to actively promote the continual improvement plans and activities of various energy conservation measures. In addition, to implementing an energy management system meeting international standards, we have established an energy management policy and made the following commitments:

• Continuously improve energy performance and reduce energy consumption costs.
• Implement the energy management system and reduce GHG emissions.
• Abide by energy regulations and prioritize procurements of energy-efficient products.
• Improve the green corporate image and promote eco-design and green production.
• Secure acquisition of information and resources to achieve energy and resources targets.

Status of Energy Consumption

• In 2021, the total energy consumption in Taiwan was 16,274 MWh and in China was 51,617 MWh. The largest was electricity consumption. The total annual electricity consumption was 15,907 MWh (accounted for 98%) in Taiwan and 49,016 MWh (accounted for 95%) in China. The proportions of the natural gas, gasoline, and diesel consumption did not reach 5%, respectively. Each plant proposes programs to improve the energy resource utility rate and reviews the implementation statute of the goal regularly by the Environmental Protection Committee.
• Total energy consumption in Taiwan decrease by 27% in 2021 compared to 2019 due to the introduction of magnetic suspension ice machines in Headquarters and Chunan plant, the implementation of electricity consumption monitoring and management, and the continued promotion of energy conservation measures, resulting in a slowdown in electricity consumption and a decrease in overall energy consumption.
• The plants in China have implemented in the improvement plan for energy saving since 2018. For example, to respond to the extreme weather caused by global warming and climate change, the plant used the energy-saving lighting equipment, introduced the energy-saving measures to the air-conditioning system, and reviewed and shared the improvement actions with the Environment Protection Committee on a quarterly basis. In 2021 the expansion of Wujiang Plant (established Coretronic Optics (Suzhou)) increased the intensity of electricity consumption by 7.7%. To reduce energy consumption, the solar system was built at the Wujiang Plant to replace ordinary electricity consumption with clean energy in order to reduce the intensity of electricity consumption.
• Chunan plant introduced the ISO 50001 energy management system in 2016 and obtained certification; also established an energy management system implementation committee with dedicated energy management personnel to establish energy management policies and employee proposal and incentive systems; systematically manages energy usage, regularly reviews energy saving benefits, and continuously promotes energy saving measures and related promotional activities.
• 100 energy saving programs were implemented from 2015 to 2021 in Chunan plant, with an accumulated reduction of 2.41 GWh of electricity, and a 1.5% reduction in electricity consumption in 2021 compared to 2020, achieving the annual electricity saving target.
