Therefore, we have established the Occupational Health, Safety and Environment Policy (OHS&E) as as a framework for managing environmental impacts and optimising resource efficiently. This policy ensures that all internal departments and stakeholders operate in alignment with environmental, social, and community responsibilities, supporting the effective achievement of the company’s goals.
Governance Structure
B.Grimm Power has established the governance structure of Occupation Health, Safety and Environment (OSH&E) to ensure effective implementation of the OHS&E policy and to promote continuous improvement through regular reviews. It is the responsibility of all employees, at all levels, to comply with and implement this policy, under the supervision of key relevant management as outlined below:
- Board of Directors (BoD) is responsible for overseeing and approving policies, setting strategic direction, and reviewing the effectiveness of the Occupational Health, Safety, and Environment (OHS&E) management system annually.
- Corporate Occupational Health, Safety and Environment (OHS&E) Committee comprising members of the Management Committee and representatives from the OHS&E Working Team, this committee is responsible for developing policies and strategies, overseeing, and regularly monitoring OHS&E performance to ensure alignment with the organisation’s goals and direction.
- Occupational Health, Safety and Environment (OHS&E) Working Team consisting of senior management representatives and professional safety officers from both the Bangkok office and power plants, the team is responsible for supervising, monitoring, reporting, and setting operational guidelines on workplace safety, environment, biodiversity conservation, and forest resource protection in compliance with relevant laws and company policies. Monthly meetings are held to communicate policies, engage with key internal and external stakeholders, exchange perspectives, and share initiatives for improving the OHS&E management system. The team also promotes collaboration and awareness among employees, contractors, business partners, regulatory bodies, and other relevant stakeholders.
Integrated Environmental Management
Environmental Management in Accordance with International Standards
B.Grimm Power is committed to conducting its business with a strong emphasis on environmental conservation through a systematic and integrated management approach. This includes establishing operational frameworks aligned with international standards, conducting environmental impact assessments, managing risks, and implementing continuous monitoring and improvement. Our environmental management framework extends across our own operations, including subsidiaries, suppliers and contractors under our control. We adhere to relevant national laws, regulations, and international standards, using the ISO 14001:2015 Environmental Management System as the primary guideline to oversee and enhance the environmental performance of our power plants. Certified power plants strictly comply with all requirements, while those in the preparation phase undergo internal audits and/or external assessments to identify areas for improvement and readiness for certification.
Environmental Impact Assessment in Compliance with Legal Requirements
All B.Grimm Power projects undergo comprehensive Environmental Impact Assessments (EIA), evaluating potential impacts on natural resources, the economy, society, and community health. These assessments inform the development of preventive and mitigation measures, environmental monitoring protocols, and action plans throughout both the construction and operational phases. For projects subject to regulatory requirements, Environmental Impact Assessment (EIA) reports are prepared in compliance with applicable laws. For projects outside EIA scope, Initial Environmental Examination (IEE), Environmental Safety Assessment (ESA), or Code of Practice (CoP) reports are conducted as appropriate. Additionally, we continuously monitor potential environmental impacts from power plant operations and implement corrective and monitoring measures as needed. Environmental Monitoring Reports are submitted every 6 months to the Energy Regulatory Commission (ERC) and other relevant authorities.
Environmental Risk Management, Auditing, and Performance Improvement
B.Grimm Power continuously monitors and analyses its environmental performance across all power plants. This includes the ongoing development and improvement of environmental performance indicator databases to ensure clarity, completeness, and consistency. Strategic goals and success indicators are set at both project and corporate levels, guiding effective planning and operations. We place strong emphasis on minimising environmental impacts and optimising the efficient, responsible use of natural resources. Environmental performance is regularly reviewed, with continuous improvements implemented across operational processes.
To strengthen risk management, we have adopted the Essential ERM platform to effectively identify, assess, manage, and monitor risks. This centralised platform consolidates both current and potential risks across the organisation, along with designated response measures from each department at the power plants and Bangkok office. Risk data is presented through a real-time dashboard, providing a comprehensive enterprise-wide overview. Key environmental risks identified include those related to natural disasters, declining raw water quality from suppliers, hazardous waste or wastewater leakage, and increased production costs due to natural gas (energy) price fluctuations.
Regular internal audits on occupational health, safety, and environmental practices are also conducted by the Corporate SHE Department. These audits cover legal compliance and standards such as ISO 14001:2015 and ISO 45001:2018, as well as general requirements on environmental and safety practices. Topics assessed include proper segregation and disposal of hazardous and non-hazardous waste, legal waste management practices, and awareness-raising on environmental and workplace safety. Audit results are documented in detailed reports highlighting improvement areas and practical corrective actions tailored for each power plant.
Circular Economy Application
B.Grimm Power recognises the limitations of the linear economy model (Take–Make–Dispose), which drives excessive waste generation and unsustainable resource depletion. In response, we have adopted circular economy principles to guide its operations, focusing on system design and comprehensive waste management to maximise resource efficiency. This approach promotes resource efficiency through reuse, recycling, and returning materials to the production cycle (Make–Use–Return), while also minimising pollution. It aligns with the 3Rs (Reduce–Reuse–Recycle) and the concept of industrial symbiosis, which encourages the exchange of waste and by-products among industries. As a result, we reduce natural resource loss, lower waste generation, and mitigate long-term environmental impacts. Circular Economy principles are embedded in our project planning and operational processes, including increasing the use of renewable energy, reducing reliance on virgin raw materials, extending equipment lifespan, and recovering waste for reuse. We also pursue collaborative initiatives to enhance resource efficiency, such as developing alternative fuels to natural gas for combined cycle power plants and investing in energy storage systems.
Energy Management
B.Grimm Power generates electricity primarily from thermal energy using natural gas as the main fuel. We place strong emphasis on maintaining and enhancing machinery efficiency to reduce fuel consumption, optimise thermal energy usage, and increase electricity output. Our energy management approach focuses on the responsible use of energy, the adoption of advanced technologies from globally recognised manufacturers, and the preparation of annual energy management reports, verified by certified energy auditors. These reports follow an 8-step energy management process:
- Establishing an energy management working team to develop plans and preventive maintenance strategies.
- Conducting preliminary assessments to evaluate the energy management status at each power plant, considering energy conservation policies, responsibilities, awareness, information systems, communications, and investment in energy-saving projects.
- Establishing an energy conservation policy to demonstrate our commitment to energy conservation efforts.
- Assessing energy-saving potential through detailed analysis of energy consumption across 3 levels: organisation, product, and equipment.
- Setting energy conservation targets and plans at both the power plant and corporate levels, along with related training programmes and awareness activities.
- Implementing the energy conservation plan including performance monitoring and analysing aligned with the established goals.
- Conducting energy management audits.
- Reviewing, analysing, and correcting areas for improvement in the energy management process.
We also promote energy conservation awareness through ongoing training and campaigns, such as Senior Personnel Responsible for Energy courses, office energy-saving programmes, and annual awareness-raising initiatives. These efforts encourage innovation and operational improvements to reduce energy use, promote energy recovery, lower operational costs, and support long-term sustainability.
Energy Management
Performance 2024
The total non-renewable energy consumption increased by 1,175,295 megawatt-hours or 7.52 percent from 2023 due to the first full 12-month data reporting from BGPAT2-3. However, the ratio of non-renewable energy consumption per unit of electricity generated remained stable at 1.23, slightly above the target of reducing this ratio by 1 percent from the previous year (not exceeding 1.22). To address this, the company implemented energy efficiency improvement initiatives, resulting in a total reduction of more than 6,867 MWh—equivalent to approximately THB 31.7 million in cost savings.

Outstanding Energy Efficiency Projects
Reduction Power and Fuel Consumption in Machinery Operations
We are committed to continuously improving machinery and equipment efficiency to reduce electricity consumption. Key energy efficiency enhancement projects includes:
- Cooling Tower System: Improved heat dissipation by reducing fan operation during low-load periods and optimising operation patterns according to required heat rejection. Modifications include adjusting the cooling tower make-up water pump operation and installing Variable Speed Drives (VSD) on cooling tower fan motors to reduce energy consumption.
- Gas Turbine System: Modified the operation of cooling fans to automatically shut down during gas turbine shutdowns without causing damage to the machinery (implemented at ABP1-2).
- Steam Turbine and Steam Pipeline System: Reduced pump operating time during shutdowns and replaced steam traps to minimise steam loss.
- Compressed Air System: Installed smaller, more energy-efficient air compressors equipped with integrated Variable Speed Drives (VSDs), enhancing operational flexibility and energy efficiency in line with production needs (implemented at ABPR3-4).
Reduction of Non-Process Electricity and Fuel Consumption
Continuous monitoring of internal electricity consumption is carried out by the Energy Management Committees at each power plant to identify opportunities for improving efficiency and reducing energy use. In 2024, initiatives were implemented to reduce electricity consumption in utility systems, such as raw water treatment, and office operations, including:
- Raw Water and Wastewater Treatment Systems: The raw water pipeline was restructured to shorten transmission distance and reduce pump usage. Variable Speed Drive (VSD) systems were also installed on water pumps to enhance efficiency. In addition, degraded solar panels from our solar power plants were repurposed to power flood prevention pumping systems within the project area.
- Lighting Systems and Office Buildings: LED lighting was expanded in project areas, and motion sensor systems were installed to automate lighting based on occupancy, optimising electricity usage in offices.
Water Management
B.Grimm Power is dedicated to conserving and efficiently utilising water resources throughout our value chain, as well as planning and managing wastewater effectively. We continuously collaborate with communities and external organisations to promote water conservation. Recognising the increasing risks of drought caused by climate change, we conduct watershed-level water risk assessments to ensure our operations do not affect community access to water. We also promote efficient water use of water in our production processes, following the 3Rs (Reduce-Reuse-Recycle) principle, such as increasing the recirculation cycle of cooling water and partially replacing freshwater usage with treated wastewater to reduce consumption and minimise drawing water from public sources. Additionally, we regularly monitor wastewater quality to ensure compliance with legal standards and prevent negative impacts on the environment and communities surrounding our power plants.
Water Related Risks Assessment
B.Grimm Power conducts annual assessments of short- and long-term water scarcity risks, evaluating both water quantity and quality risks (Water Stress1) across our operating sites using the AQUEDUCT Water Risk Atlas developed by World Resources Institute. In 2024, it was found that 78.7 percent or 37 out of 47 B.Grimm Power's projects2 were located in areas classified as high to extremely high water-stressed . These projects accounted for 16.41 million cubic metres, or 77.37 percent of the total net freshwater consumption. They also contributed 88.2 percent of total cost of sales and services.
All combined-cycle power plants are situated in high to extremely high water-stressed areas. In respone, we prioritise sustainable water management, particularly by reducing dependency on natural water sources. This is achieved through the reuse of treated wastewater from the industrial estates where the power plants are located. Furthermore, internal water recirculation is optimised, such as increasing cooling tower water recirculation cycles to maximise water use efficiency. We also actively engage stakeholders through regular meetings with industrial estate operators and surrounding communities to understand concerns, jointly develop risk mitigation strategies, and plan future water demand management. We also prepare annual water scenario planning as part of our Business Continuity Plan (BCP), to assess external water source trends and establish emergency water supply plans, ensuring uninterrupted plant operations while safeguarding community access to water.
For other types of power plants, 84.2 percent of solar power plants are located in high to extremely high water-stressed areas, although water consumption is minimal at 0.03 cubic metres per megawatt-hour. Meanwhile, wind and hydropower plants are not situated in high to extremely high water-stressed areas. Nevertheless, we remain vigilant in monitoring water-related impacts across all types of power plants, recognising water as a vital operational input and a natural resource that must be preserved to ensure long-term sustainability.

1 Water stress: “When withdrawals are greater than 20 percent of total renewable resources, water stress often limited development opportunities; withdrawals of 40% or more represents high stress. Similarly, water stress may be a problem if a country or region has less than 1,700 m3/year of water per capita (Falkenmark and Lindh, 1976).” Source: IPCC Report 2001.
2 The scope of water scarcity risk assessment covers B.Grimm Power and its subsidiaries both in Thailand and oversea, representing 99.6 percent of total revenue. Exceptions include the Malacha Hydropower plant, which was invested in during the year. The scope of assessment excludes solar rooftop projects, as their water consumption is minimal and poses no material risk. It also excludes the LNG trading business, which commenced operations in Q3/2024.
Water Quality Management
B.Grimm Power has implemented a water quality management system at its combined cycle co-generation power plants to ensure that all wastewater complies with regulatory standards before being discharged into the central treatment systems of respective industrial estates. Monthly inspections are conducted by in-house chemists specialising in water quality testing, along with external assessments. These procedures are carried out in accordance with relevant laws and regulations, such as the Environmental Quality Promotion and Conservation Act B.E. 2535, and the Industrial Estate Authority of Thailand (IEAT) wastewater discharge regulations. They are also aligned with the impact prevention and mitigation measures outlined in each project’s Environmental Impact Assessment (EIA) report.
Although renewable power plants have relatively low water usage and generate minimal wastewater, water management remains a priority. The focus is to ensure that operations do not negatively affect surrounding areas. In rare cases where water diversion may occur due to natural events, rigorous monitoring and control measures are enforced to maintain compliance with local legal and environmental standards.
Water Management
Performance 2024
The net freshwater consumption increased by 1.53 million cubic metres or 7.8 percent from 2023 due to the first full 12-month data reporting from BGPAT2-3. However, the ratio of net freshwater consumption per unit of electricity generated was 1.43 cubic metres/MWh, slightly above the target of reducing this ratio by 1 percent from the previous year (not exceeding 1.41 cubic metres/MWh). To address this, we implemented water efficiency improvement projects that successfully reduced water usage by over 427,100 cubic metres, equivalent to a cost saving of approximately THB 5.2 million. For wastewater management, the company ensures all discharged water is treated in compliance with relevant standards and regulations before being transferred to the central wastewater treatment systems of each industrial estate. Monitoring results in 2024 confirmed that no cases of effluent exceeded the legal quality thresholds.

Waste Management
B.Grimm Power recognises the importance of adopting a circular economy, where the value of resources extends beyond the lifespan of individual products. This model promotes the reuse and recycling of existing resources through systematic and comprehensive waste management. By embracing this approach, we aim to reduce waste, maximise resource efficiency, and minimise our environmental footprint, particularly greenhouse gas emissions, which pose a critical global challenge.
We are committed to managing our production waste by focusing on minimising waste generation and maximising waste utilisation to ensure minimal residual waste. Our goal is to achieve Zero Waste to Landfill by implementing the 3Rs principle (Reduce-Reuse-Recycle). This includes reducing waste generation, reusing materials, and processing waste for reuse wherever possible. Additionally, we actively promote waste segregation into categories such as general waste, biodegradable waste, recyclable waste, and hazardous waste to ensure proper waste management. This approach optimises resource use, reduces costs, and minimises environmental impacts that could affect communities surrounding our power plants.

Outstanding Waste Management Projects According to 3Rs Principle
Reducing waste generation
Waste Reduction through Process and Chemical Optimisation
- Reduced chlorine usage over 90 metric tonnes per power plant per year by supplementing chlorine with food-grade industrial biocides during the raw water conditioning process, which improved water quality and reduced the volume of wastewater requiring treatment prior to discharge.
- Reduced sludge generation from water treatment processes by over 100 tonnes per power plant per year by reducing the use of Ferric Chloride in water treatment processes.
- Reduced chemical consumption for raw water treatment by an average of over 100 tonnes per year by optimisng chemical dosing based on raw water quality, resulting in cost savings of THB 400,000-500,000 per year.
Equipment and Spare Parts Life Extension Programme
- Extended the lifespan of air filters (pre-filters and final filters) from 12 and 24 months to 14 and 36 months, respectively. This adjustment was based on actual usage data and supported by the installation of differential pressure gauges to determine the optimal replacement time.
- Extended the replacement interval for lubricant oil filters from every 6 months to once a year, reducing both waste generation and spare part costs.
- Promoted the repair of damaged equipment instead of purchasing new parts, with notable implementations at ABP3 and ABP4–5 power plants. Solar power plants also repaired diodes in solar panels and reused wiring from damaged panels. These efforts led to a total cost saving of over THB 20.6 million.
Reuse/Recycle
- Soil conditioner from treated sludge Since 2016, ABP3 has pioneered the transformation of sludge from water treatment systems into soil conditioners. The initiative has since expanded to other power plants, reducing sludge disposal over 300 metric tonnes per plant annually. The soil conditioner is tested and verified to be safe for agricultural use before being donated to nearby schools and communities.
- Recycled plant pots from used air filters Used air filters from gas turbine systems have been upcycled into plant pots, adding greenery to the power plant premises while creating value from waste materials. Since the project's launch in 2020, a total of 770 filters have been repurposed and donated to local schools.
- Repurposing degraded solar panels In 2024, the pilot project “Second Life Solar PV” was launched to reuse degraded solar panels. These panels were adapted to generate electricity for lighting and office facilities at ABP4–5 power plant, resulting in 1,953 kilowatt-hours of electricity generation and annual cost savings of THB 6,838.
Waste Management with Minimal Environmental Impact
Diverted Over 46 Tonnes of Waste from Landfill through the Zero Waste to Landfill initiative launched in 2024 at the ABP and ABPR power plant groups. This project promotes sustainable waste management by shifting disposal methods towards resource recovery, such as selling certain waste types for recycling or converting them into Refuse-Derived Fuel (RDF). Notably, the ABP group successfully achieved Zero Waste to Landfill within the past year.
Air Quality Management
B.Grimm Power places great importance on controlling air pollution to minimise its impact on surrounding communities and the environment. We have established robust air quality management guidelines and measures to ensure thorough monitoring, assessment, and control. Air emissions from all combined cycle co-generation power plants are continuously monitored both within the plant premises and in nearby communities that may be affected. To further reduce environmental impact, we also implement operational process improvements, maintain machinery regularly, and upgrade equipment using advanced technologies to enhance efficiency and reduce emissions.
For our combined cycle co-generation plants that use natural gas as the primary fuel, Dry Low NOx (DLN) burners with automated systems are installed to control nitrogen oxides (NOx), the main air pollutant from these operations. We also utilise Continuous Emission Monitoring Systems (CEMS) to measure air pollutants emitted from stacks in real time. These systems are complemented by routine audits every 1–3 years and random stack sampling at Heat Recovery Steam Generators (HRSG) to monitor levels of nitrogen oxides (NOx), sulphur oxides (SOx), dust, oxygen (Oâ), stack temperature, and flue gas flow rate. The sampling and testing procedures comply with the U.S. Environmental Protection Agency (U.S. EPA) standards and are conducted in accordance with regulations issued by the Ministry of Industry. In addition, ambient air quality in surrounding communities is regularly monitored and measured every 6 months.
Performance 2024
Overall, Nitrogen Oxide (NOx) and dust emissions increased due to the first full 12-month data reporting from BGPAT2-3. However, we have ongoing efforts to reduce air emissions such as optimising gas turbine control parameters to enhance combustion efficiency which helps lower NOx concentrations. All air quality parameters complied with legal and regulatory standards without any complaint related to air pollution in 2024.
