Review of Use of Energy Resources
The energy resources used at Innolux are mainly electricity, diesel, and natural gas. In 2018, a total of 20,543,950GJ of energy were consumed, of which power consumption made up the largest proportion. Power consumption for the year was 19,774,347GJ, accounting for 96.3% of total energy resources used, followed by natural gas at 508,510GJ, or 2.5%, and diesel at 261,094GJ, or 1.2%.

Review of Power Consumption Efficiency

In 2018, Innolux consumed 5,493GWh in total. The Taiwan sites consumed 5,117GWh, accounting for 93.2%, and the mainland China sites consumed 376GWh, or 6.8%.



In 2018, the unit output area power consumption at TFT-LCD plants in Taiwan was 67.2kWh/m2, a 2.4% decrease from 2017’s 68.8kWh/m2, which achieved the 2% target.


At mainland China sites, power consumption per unit output quantity was reduced by 1% at Ningbo, 1% at Foshan, 2% at Nanjing, and 1.5% at Shanghai compared to 2017. Analysis showed that the 1.4202kWh/pc at the Ningbo site and 3.39kWh/pc at the Foshan site reached the target. However, the Nanjing and Shanghai sites, in spite of their continued efforts to promote power savings, failed to achieve the target because the two sites underwent modification to produce items with high unit prices and the automation systems and new production processes consumed more power.

Jhunan The clean rooms on the 3rd, 5th, and 7th floors and RCC pump in the SUP Building were shut down to stop power consumption. 367,200 1,321.9
The first stage of power consumption reductions in the uninterrupted power supply system was completed. One of the DUPS machines can now be shut down to save energy and reduce maintenance expenses. 700,800 2,522.9
Inverters (60HZ->48HZ) were installed on the MAU washing pumps in the Array 1 Plant and the SUP Building.
Inverters (60HZ->45HZ) were installed on the MAU washing pumps in the Array 2 Plant and Array 3 Plant.

Tainan The air compressor coolers rusted and cooling efficiency dropped. They were replaced with new coolers to recover the performance standard and reduce energy consumption. 1,460,899 5,259.2
The old vacuum machines ran at a fixed frequency and a number of them operated at full capacity to meet maximum demand. In reality, however, demand varied and the unnecessary operation was a waste of energy. Therefore, new variable-frequency vacuum machines were installed to allow adjustment in accordance with actual needs. 2,688,122 9,677.2
A coating was added to the pumps to reduce friction and increase energy savings.
‧Coating was used first on pumps with greater than 200HP capacity.
‧Machines needing repairs and maintenance were consolidated. Rust removal, cleaning, and coating were performed on the runners to reduce friction on the surface.
‧New machines were purchased and coated before they entered the plant
497,403 1,790.7
Ningbo High-performance compressor stations were installed and Energy Performance Contracting (EMC) was adopted to bring in high-performance compressors to reduce energy consumption and operating load at the same time. 631,870 2,274.7
Foshan Water was used to replace iced water to cool compressors while saving on power consumption. 776,190 2,794.3
Water-chilling system engineering: The difference between peak and off-peak electricity rates was utilized. Cylindrical containers were installed to store cold water at nighttime and release the coldness in daytime to decrease electricity consumption. -- --
