Energy consumption

There are two types of energies that Tatung consumes – direct energy and indirect energy. Direct energy sources are from diesel fuel oil, LPG, and diesel. Indirect energy source is purchased electricity from Taiwan Power Company. The most consumed energy in 2016 was purchased electricity and the amount was 199,598.13 GJ(90.38%) which equaled to 55,443.93 kkw-hr; followed by LPG with 13,753.87 GJ (6.23%) which equaled to 272.52 tons. The total amount of energy consumption in 2016 was 79,629.69 GJ lesser than in 2015, which was 26.50% reduction. The main reason was Crystal Growing Center was no longer operated by Tatung. When compares to 5 years ago, there is 48.19% reduction in total.

Greenhouse gas emission

In order to investigate the amount of GHG emission thoroughly and comply with the regulation, Tatung actively implements ISO14064-1 greenhouse gas management system into three factories. Once the GHG inventory is completed, verification will be conducted by the third party based on reasonable level of assurance. For the purpose of enhancing the ability to do greenhouse gas inventory in the factories, Tatung runs ISO14064-1 Internal Verification Class every year. We are expecting to have more well-trained employees through these classes and they are able to do the greenhouse gas inventory well and pass the verification by the third party in the future.
Due to Tayuan Plant and headquarter is still undergoing the establishment of ISO14064-1, the GHG emissions (scope 3 is not included) in this report are calculated as follows: the amount of energy sources disclosed in previous paragraph multiplied by each emission factor. The total GHG emission in 2016 was 30,702.54 tons CO2e, 95.35% of the emission was from purchased electricity. The second largest portion was from LPG which was 2.83%. The emission was 11,120.52 tons CO2e lesser than in 2015. When compares to 5 years ago, there is 50.59% reduction in total.

Energy saving and GHG reduction

Global warming greatly increases the frequency of extreme weather and directly causes impacts to the operation of a business. In order to fulfill corporate social responsibility and reduce operating costs, Tatung sets short and medium term goals which are based on energy intensity per product and the baseline year is 2013. The goals are: Short term – reduce 3% in 2016, Medium term – reduce 6% in 2018. The result for each year is listed as follows:
From the table we can see there are few represented products did not meet the target due to the production amounts were less. In order to understand where are the significant power consumption areas, the headquarter and the factories have completed "The first phase: smart power monitoring system" project. The project installed smart meters and monitoring systems on the main power circuits to instantly monitor the real-time energy consumption, energy demand, power factor and other important information. The historical records were used to enable more accurate energy management works. We will have "The second phase: the monitoring and management of significant energy consumption equipments" project in 2018. The project will implement temperature control and power scheduling management to the air conditioners at public area, the office, and the telecommunication room. For the production equipments which have large energy consumption and long operating times will be installed monitoring systems to define the variables may affect the energy efficiency. The variables will be managed to save the energy. Other the other hand, energy management staffs in the factories will inspect the work sites from time to time to find out a place where energy is wasted or can save energy and propose energy saving plans. The company will also participate in Taipower Company's demand suppression activity to supplement the power supply system's reserve capacity in order to make efforts to energy conservation and carbon emission reduction to the nation.

To achieve the goal, Tatung conducts annual energy audit and reports the energy consumption information to the government as well as implements energy saving projects in the headquarter and the factories. In the subsidiaries, Tatung checks the energy saving performances during 3P program on-site audit to ensure the energy saving target can be achieved. In 2016, Tatung reduced about 2 million kwh of purchased electricity consumption via 5 dimensions which equaled to 1,086 tons of GHG emission reduction (2.8 Daan Forest Park's carbon reduction amount).

In addition, San-Hsia Factory has implemented ISO 50001 energy management system and passed certification in 2015. In 2016, Tayuan Plant and Taoyuan Wires and Cables Plant have also completed implementation of ISO 50001 and passed the certifications. We commit that we will continue to conduct energy review to find out where the energy is greatly consumed according to ISO 50001 and tries hard to reduce the amount of energy without compromising the quality of products.
