Development of Renewable Energy

      Taiwan Sugar Corporation promotes bagasse power generation, waste heat generation from waste incineration, solar power generation and biogas power that uses livestock excreta and biogas with bio-potential agriculture waste materials. We are studying the feasibility of overall use of renewable energy in 3-5 years, aiming at setting an example of zero energy consumption (renewable energy output= total electricity consumption) for the manufacturing industry in Taiwan for the promotion of the renewable energy market in Taiwan, supporting the transition process toward a low carbon future. In 2018, the total power generation from green energy and renewable energy amounted to 34.43049 GWh, reducing approximately 190,744.9 tons of CO2e.

Long-term Goal Project Content Schedule
Independent supply of green energy Relevant power supply plans and facilities procurement and contract issuing are carried out based on the green energy gap and the progress of related progress of solar PV power generation and biogas power generation projects. The rooftop solar PV energy generation and biogas power generation in the TSC’s livestock farms will be completed in 2021.
Consolidate the company’s land data and invite solar PV manufacturers to discuss the feasibility and ask for their recommendations for whether to make the investment for the operation of solar PV equipment or to lease it. In the forms of providing land, cooperative construction or lease for the royalties, the company is expected to complete the installation of equipment with the capacity of 123 MW and will increase the installation year by year.    
Regional energy and resource center for agricultural waste Evaluate the feasibility of eliminating the old direct-fired boilers and renovating them into new gasifiers in Huwei and Shanhua Sugar Refinery. The waste heat of the gasifiers can be used as a source of thermal energy for the rapid fermentation drying system.  The evaluation of bagasse and pig manure or biogas residue solidification technology will be completed in 2019.
Evaluate and research the way to recycle agricultural waste for the use of feed or fertilizer. The remaining unusable parts can be decompressed to reduce moisture to be used as fuel. 
Evaluate the establishment of a storage site for agricultural waste sources and/or transport and store them in RDF-5 fuel rods.  
The exploration of the energy production model of sugar factories is expected to be completed in 2019~2020.

Solar Power Generation Plan

      2.89 MW rooftop PV systems have been installed in TSC’s three sugar factories (Xiaogang, Huwei, and Shanhua), 40 gas stations, Nanshalun Livestock Farm and Evergreen Plaza Hotel. The installation of 857.4KW rooftop power generation equipment on the roofs of large-vehicle parking lots in Kaohsiung started from January 2018 and is scheduled to complete the installation at the end of January 2019. Inventory and planning of a total of 131.45MW solar power generation equipment has been conducted in 11 flood detention pools, roofs of 104 buildings, 16 livestock farms and the Dong Hai Feng Agricultural Circular Park.    
      The cooperative construction project of ground-type power generation equipment in the factory area of the closed Dalin Sugar Factory has completed the grid-connection on October 18, 2018, with the capacity of 1MW. We have also taken inventory of 520 hectares of land unfavorable for farming and will plan the construction of ground-type power generation equipment in the future. 

Agricultural Waste Resources for Power Generation

      To develop renewable energy and implement circular economy, TSC applies agricultural waste resources in power generation. The total capacity of the green electricity from agricultural waste resources amounted to 340.1471 million kWh.

Utilization of remaining sugarcane bagasse for cogeneration Huwei and Shanhua Refineries of the Sugar Business Division make use of the remaining bagasse for power generation for their own use, generating 10.5654 million kWh of electricity in 2018.
Use waste heat from incineration for power generation Kanting and Gangshan Refuse Incineration Plants of the Environmental Protection Business Operation Center utilize the waste heat generated by incineration of waste for power generation. In 2018, 329.1934 million kWh of electricity was produced, and among all, 79.3292 million kWh was for self-use, while the remaining 249.8642 million kWh was sold to Taiwan Power Company.
Use of pig manure and urine for biogas power generation In the four livestock farms of the Livestock Business Division, pig manure and urine are used for biogas power generation through the anaerobic digestion process. In 2018, 388,300 kWh of electricity was produced, and among all, 116,900 kWh was for self-use, while the remaining 271,400 kWh was sold to Taiwan Power Company.
