Management Approach
The main energy-consuming activities in the Company’s operation are as follows:
The Company remains committed to continuing the process to ensure that its overall use of energy, both from electricity and fuel, is efficient. Approaches to reduce the use of energy are as follows:
Energy Saving in Office Building
The Company has organized "ALL SAVE ALL WIN" project to cultivate energy conservation awareness among its employees across Bangkok, Chonburi, and Rayong offices. This initiative is designed to nurture environmental consciousness and promote collective engagement in energy conservation and responsible utilization of natural resources through the implementation of the following actions:
- Promote the practice of turning off air conditioners and unused lights during the one-hour lunch break
- Encourage staff to use stairs instead of elevators
- Maintain the office air conditioning temperature at no lower than 24 degrees Celsius
- Turn off computer monitors when not in use
- Replace 46-watt fluorescent bulbs with energy-saving 18-watt LED bulbs
- Schedule air conditioning maintenance at least twice a year
Furthermore, the Chonburi office has reduced conventional electricity consumption by installing solar-powered spotlights in the parking area, increasing its use of solar energy.
In 2023, the Company's office buildings had a total electricity consumption of 877,150 kWh, representing a 33.24% increase from 2022. This increase can be attributed to a continuous and positive trend and direction following the COVID-19 pandemic, with employees returning to work in the office and engaging in more office activities.
Energy Saving in Common Areas
In terms of road lighting systems within the industrial estates, the Company is responsible for all maintenance. In 2023, it achieved a 4.67% reduction in energy usage in these common areas compared to 2022, with all lighting now using 100% LED bulbs. Additionally, the Company began installing solar cell lighting systems at 88 locations in 2023, with plans to continue expanding these installations in the coming years to further reduce electricity consumption. Furthermore, the Company has implemented intelligent control and monitoring systems for the lighting control panels and developed a platform for effective management of the lighting systems' operations. As part of its sustainability commitment, a total of 190 solar traffic lights were installed in both AMATA City Chonburi and AMATA City Rayong Industrial Estates, significantly contributing to the reduction in overall electricity consumption.
The Company installed additional smart weather stations that exclusively utilize solar energy for their control units in 2023. Three stations were installed in AMATA City Chonburi Industrial Estate and four in AMATA City Rayong Industrial Estate this year, bringing the total number of smart weather stations to 11.
In 2023, the Company was able to reduce purchased electricity consumption from non-renewable sources to 32.71 million kilowatt-hours, a decrease of 6.4% compared to the base year of 2019. However, there was an increase of 6.3% compared to 2022, attributed to employees returning to work in the office and increased office activities. This increased consumption encompasses usage for various essential systems, including raw water pumping systems, water supply systems, and wastewater collection systems into the central wastewater treatment system, which significantly increased due to increased water usage by industrial estate operators.
Promotion of the Use of Renewable Energy in the Company's Public Utility System
The Company encourages subsidiaries in its supply chain to increase energy management efficiency and reduce electricity consumption, particularly in industrial water systems, which are the most energy-intensive activities. AMATA Water Co., Ltd., which is responsible for water and wastewater management in AMATA Industrial Estates, has therefore conducted a study on utilizing renewable energy from solar power to replace conventional electricity in the operational process and has installed solar panels on the roof of the water reclamation system building since 2017. Furthermore, in 2019, AMATA Water Co., Ltd. started to develop a plan to install floating solar panels in its reservoirs. Currently, annual solar-generated electricity replacement consumption is 4,004,318 kilowatt-hours, which represents 7.62% of the total electricity consumption of the water supply system, wastewater treatment system, reclamation system, and raw water pumping system. As a result, greenhouse gas emissions were reduced by 2,002 tons of carbon dioxide equivalents per year.
In 2023, the Company consumed all types of energy within and outside of the organization for main activities in its supply chain, totaling 212,315.13 gigajoules, an increase of 9.4% compared to 2022, and the energy consumption intensity in 2023 was 6.38 gigajoules per rai, or 39.88 gigajoules per hectare, an increase of 1.3% from the 2019 base year. This rise is attributed to employees returning to the office and an increase in office activities, and the expansion of company operations. However, the Company remains steadfast in its commitment to increasing the use of renewable energy, reducing energy consumption, and enhancing energy efficiency in the future.
