Energy Management

Energy Management

In 2022 non-renewables including natural gas and purchased electricity were the major types of energy we consumed, while diesel was the second highest. The total 2022 energy consumption included 6.8197m3 of natural gas, 73.5551 GWh (including non-renewables and renewables) of electricity, 1.234Ml of petroleum, and 1.994Ml of diesel. In terms of heat value, it was 522,826.11 GJ (109 joule), reducing by 1.94% over 10,339.90 GJ in 2021.

Self-developed renewables

In 2021 we began to build solar PV systems in each plant for self-generation of electricity for self-consumption to reduce purchased electricity and carbon emissions. The solar PV projects at Yunlin Tech Plant and Taoyuan Plant were completed in 2022. Operation will start in 2023Q1 to supply electricity for self-consumption. The annual general capacity of all plants will reach 2.53GWh. In 2023 we will continue the PV system expansion of Yunlin Tech Plant.
