As a result of the global emphasis on social and environmental responsibility in the industrial sector, which includes the reduction of greenhouse gas emissions resulting from different forms of energy use, the Company consumes a considerable amount of electricity to manage all its industrial estates. Additionally, major domestic and international companies that operate in industrial estates are increasingly interested in adopting renewable energy. Failing to meet the current and future demands of customers may have long-term consequences for the Company's competitiveness and revenue generation.
The Company perceives an opportunity to develop products and services to meet the needs of current and future customers, such as the production and use of clean energy in industrial estates, promoting the use of electric vehicles, and selecting technologies that increase energy efficiency, etc. The Company is committed to becoming a carbon-neutral city by 2040 through the implementation of the Smart Energy project, which is one of the projects under the AMATA Smart City initiative. This project primarily focused on leveraging renewable energy sources and deploying smart grid technologies to optimize energy utilization and bolster power system resilience. The adoption of clean energy will preserve the environment, mitigate pollution from fossil fuel power plants, and lower greenhouse gas emissions. These opportunities will help mitigate the impact on the industrial sector, build confidence, and generate income and competitiveness for the Company.
The main energy-consuming activities in the Company’s operation are as follows:
Electricity is the primary energy source used in company operations and a significant indirect source of greenhouse gas emissions (Scope 2). Therefore, the Company has established an energy management policy under its “Climate Change Management Policy” to demonstrate its commitment to efficient energy use, especially electricity. Efforts include reducing non-renewable electricity consumption through technology and innovation and seeking safe, environmentally friendly renewable energy sources. The Company also aims to increase the proportion of renewable energy use in its operations to reduce greenhouse gas emissions and support sustainable business practices.
The Company has established operational guidelines to reduce electricity consumption in main business processes, assigning shared responsibility to employees and contractors involved in each activity to ensure the achievement of established targets.
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 encourage all employee participation in energy conservation and responsible utilization of natural resources through the implementation of the following actions:
Furthermore, the Chonburi Office has increased the use of solar energy to replace electricity consumption by installing solar cell spotlights to provide lighting in the parking area.
In 2024, the Company's office buildings had a total electricity consumption of 619,789 kilowatt-hours, representing a 29.34% reduction compared to 2023. The reduction in energy consumption is the result of sustained and proactive energy-saving measures, such as transitioning to energy-efficient LED lighting systems, performing regular maintenance on air-conditioning units to optimize performance, and promoting employee engagement in environmentally friendly behaviors to reduce overall energy use.
The Company is responsible for managing common areas within its industrial estates, including overseeing the street lighting systems throughout both estates. At present, all lighting fixtures in shared areas have been fully converted to LED bulbs to enhance energy efficiency. To further improve electricity usage efficiency, the Company has installed smart control and monitoring systems for street lighting operations, replacing the previous control system that relied on sunlight sensors combined with timers. There is a possibility of system abnormalities in the main power supply causing the streetlights to remain on during the day or malfunction at night. This leads to energy wastage and customer complaints, as well as increased safety risks due to aging equipment and streetlights mounted on regional electricity poles, resulting in higher chances of power loss and leakage.
To address these challenges, the Company developed and implemented its own smart streetlight control boxes at AMATA City Rayong Industrial Estate, installing 10 units in 2023 and an additional 20 units in 2024. Additionally, they developed a platform to record and view lamp operation data and electricity usage information. This platform enables real-time control of streetlight switching via mobile applications, computers, and tablets. Furthermore, it includes a notification system (LINE notification) to alert authorities in case of electrical malfunctions, allowing efficient monitoring of streetlight status by the AMATA Command Center (ACC) security personnel.
In addition, in 2024, the Company expanded the use of solar-powered equipment across common areas within AMATA City Chonburi and AMATA City Rayong Industrial Estates.
As a result of these initiatives, total electricity consumption for street lighting within the industrial estates was 587,224.84 kilowatt-hours in 2024, representing an 18.84% reduction compared to 723,575.5 kilowatt-hours in 2023.
The Company installed 11 smart weather stations that exclusively utilize solar energy for weather forecasting and monitoring to promptly track atmospheric changes. This allows for efficient water reservoir management within the industrial estates and enhances preparedness for climate variability and extreme weather conditions.
In 2024, the Company upgraded the water distribution system at the Khao Ta Paek pumping station, a key booster station serving the AMATA City Rayong Industrial Estate. The upgrade aimed to improve both water distribution efficiency and energy performance. As a result, the Company successfully reduced electricity consumption for water distribution from 0.249 kilowatt-hours per cubic meter to 0.142 kilowatt-hours per cubic meter, representing a 43% reduction.
As a result of these initiatives, the Company successfully reduced its purchased non-renewable electricity consumption across all business operations to 26.21 million kilowatt-hours in 2024, representing a 24.98% reduction compared to the 2019 base year and a 19.86% reduction compared to 2023.
In addition to improving energy efficiency and reducing energy consumption across business operations, the Company actively promotes the adoption of renewable energy in various activities, particularly within industrial water systems, representing the most energy-intensive operations. AMATA U Co., Ltd., responsible for managing water and wastewater treatment within AMATA Industrial Estates, has been tasked with implementing solar energy solutions to replace conventional electricity. Since 2017, the Company has installed rooftop solar panels on its buildings housing the Water Reclamation System. In 2019, the Company further developed and planned the deployment of floating solar panels in its reservoirs. Currently, annual solar-generated electricity replacement consumption is 4.47 million kilowatt-hours, which represents 8.73% 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 2,237 tons of carbon dioxide equivalents per year.
In 2024, the Company consumed all types of energy within and outside of the organization for main activities in its supply chain, totaling 187,178.49 gigajoules, reduced by 11.85% compared to 2023, and the energy consumption intensity in 2024 was 5.56 gigajoules per rai, or 34.74 gigajoules per hectare, reduced by 13.08 % from 2023 and 11.76 % from the 2019 base year. This reduction in energy consumption is primarily attributed to improved efficiency in utility systems, particularly the upgrading of industrial water pumping systems. The proportion of renewable energy use in the Company’s business operations reached 8.61% in 2024, up increasing from 6.79% in 2023, aligning with the Company’s stated targets. The Company remains firmly committed to increasing its proportion of renewable energy use, reducing overall energy consumption, and enhancing energy efficiency to the fullest extent possible.
