A company-wide project to assess the energy consumption
of each production process and identify opportunities for
energy efficiency. The project has enabled distilleries to
reduce energy consumption by applying new technology.
For example, beer and spirit product groups installed
once-through boilers to increase energy efficiency and
reduce the use of non-renewable fossil fuels. The beer
product group cut its use of coal by 428 tons per year,
resulting in a reduction of 702 tCO2e emissions per year.
The spirit product group was able to lower fuel oil consumption by 280,823 liters per year, which decreased greenhouse gas emissions by 836 tCO22e per year. In addition, the beer product group has introduced the use of high-efficiency motors, which reduced electricity consumption by 150,000 kilowatt hours (kWh) per year, and reduced emissions by 87.3 tCO2e per year.
This project consists of the installation of solar panels on the rooftops of 27 factories in Thailand, and one factory in Myanmar. The installation will be completed by 2025, with a total capacity of 20 megawatts (MWp). It is projected to reduce the amount of electricity purchased from the Provincial Electricity Authority by 26,000 megawatt hours (MWh) per year, and lower greenhouse gas emissions by 12,000 tCO2e per year. It is expected that the project will reduce the cost of electricity purchased from the Provincial Electricity Authority by 96,200,000 baht.
Two additional biogas plants will be constructed in Nakhon Sawan and Nong Khai provinces, in addition to the five existing biogas plants in Prachin Buri, Khon Kaen, Ubon Ratchathani, Buriram, and Surat Thani provinces. The biogas plants use the by-products of alcohol distillation to generate energy. Vinasse, a by-product of the spirit distillery process, produces methane as a fuel for steam production, and can also be used to generate electricity. This can reduce average annual fuel oil consumption by 2 million liters per factory per year, and lower greenhouse gas emissions by 38,000 tCO2e per factory per year. The electricity produced from biogas can be transmitted back to the grid.
