Clean Energy Towards Net Zero

Global Power Synergy Public Company Limited (GPSC) recognizes the risk and potential impacts of climate change. These impacts manifest themselves in different forms of natural disasters, such as storms, floods, rising sea levels, and drought, which have shown increasing severity and frequency. Such disasters may cause business disruptions in the form of water shortage for production or damage to operational machines/facilities. In addition, GPSC prioritizes the use of energy that does not generate carbon dioxide (decarbonization) through renewable energy production, which will help reduce greenhouse gas (GHG) emissions in the country and respond to changing consumer demands.

Currently, the global community places a high level of importance on the issue of climate change induced by greenhouse gases emitted by human activities. In response, the United Nations Framework Convention on Climate Change (UNFCCC) was founded. Based on this framework, various guidelines, requirements, and international cooperation have been developed to continuously reduce greenhouse gas emissions. Additionally, the Sixth Assessment Report (AR6), released by the Intergovernmental Panel on Climate Change (IPCC), states that “setting a goal to achieve net-zero greenhouse gas emissions by 2050 is too late to keep the global average temperature increase under 2Co compared to the pre-industrial times by 2100, at which point humans will be unable to reverse the impact of climate change.” The study’s results have prompted various countries to move up their net-zero greenhouse gas emissions targets.

However, in the wake of the UN Climate Change Conference in Glasgow (COP26), which centered on three topics 1) the expansion of greenhouse gas emission reduction targets, 2) adaptation to intensifying climate change, and 3) mobilization of finance, technology, and knowledge by developed countries for developing countries, the Glasgow Climate Pact was formed to support the three topics on the agenda. As a member nation, Thailand has declared its National Determined Contributions (NDCs) to reduce greenhouse gas emissions by 40% by 2030 as well as to achieve carbon neutrality by 2050 and net-zero carbon emissions by 2065, in line with Sustainable Development Goal (SDG) 13: Climate Action.

In 2022, the UN Climate Change Conference in Sharm El Sheikh (COP27) focused on establishing a loss and damage fund in response to intensifying global warming and climate change-induced natural disasters and reiterated the pledges of the member states at COP26 to raise a fund of 10 billion USD per year, take action to bring the Glasgow Climate Pact to fruition, make efforts at all levels to curtail the rise in global temperature as per the Paris Agreement, and develop a new Climate Solidarity Pact, pushed forward by small countries vulnerable to climate change.

As a member of the global community, GPSC is committed to providing its full support and collaborating actively with every sector to achieve the challenging goal of reducing greenhouse gas emissions by adopting the following climate change policy and management approach.

Climate Change Management Approach
GRI 3-3

GPSC has established a climate change policy with the expectation that every business unit throughout GPSC Group’s supply chain will adhere to the policy at each step of the project, starting from planning and designing all the way to implementation and completion.

In light of clean energy trends, which have amplified the role of renewable energy in the electricity business, GPSC has established strategies in response to climate change under the concept of “Moving towards a Low-Carbon Electricity Business and Net Zero Greenhouse Gas Emissions” through technology and innovation development and through the use of internal carbon pricing (ICP) in order to manage risks and seek new market opportunities to handle impacts of climate change. In addition, GPSC has set targets to achieve carbon neutrality by 2050 and net zero emissions by 2060 through four key action plans, as described below.

Reduce fossil fuel usage

  • This plan seeks to reduce GHG emissions from electricity production and consists of four sub-plans:
    • Adoption of best practices for operational excellence
    • Fossil-fuel plant retrofitting
    • Fuel and energy consumption reduction
    • Internal renewable energy consumption in place of fossil fuels

Grow renewables

  • This plan seeks to increase the production of renewable energy and consists of five sub-plans:
    • Phasing down fossil fuel-based power plants, with priority on coal
    • Investment in renewables through new projects or mergers and acquisitions both domestically and internationally, focusing on solar and wind energy, which are high potential energy sources.
    • Fuel switching from fossil fuels to renewables.
    • Considering green hydrogen (H2) as an alternative source of energy
    • The use of biomass with and without carbon capture, usage and storage (CCUS) technology

The production of energy from renewable energy, be it solar, hydro, wind, and biomass energy, all of which cannot be exhausted and are renewable in nature, has low environmental impacts as it emits significantly less GHGs in comparison to fossil fuel-based energy production.

As such, in order to promote decarbonization, GPSC recognizes the importance of increasing the proportion of renewables-based energy production as a driver of greenhouse gas emission reduction. To this end, GPSC promotes the use of clean energy towards a low-carbon society, in line with the S2: Scale-up Green Energy strategy; the increased development of clean energy projects, including both solar and wind energy; and the integration of renewable energy with energy storage systems. GPSC’s long-term goals are to increase the proportion of renewable energy to 7,236 megawatts in 2025, thus amping up its renewables-based electricity production to 38%.

GRI 102-15

In 2022, GPSC conducted a climate change risk and opportunity assessment in order to formulate measures for coping with impacts and for creating new business opportunities, which are integrated into GPSC’s corporate risk management under the operations of the Task Force on Climate-related Financial Disclosures in order to assess two main types of risks: risks from physical changes and risks from other changes. In addition, GPSC reported its risk analysis method utilized to supplement the severity and likelihood assessment through a scenario analysis.

The Climate Change Management and Corporate Sustainability Taskforce has developed a comprehensive risk assessment to encompass all stakeholders in the value chain, namely suppliers (upstream) and customers (downstream), taking into account the following:

  • Scientific evidence identifying physical shifts based on the findings of the Intergovernmental Panel on Climate Change (IPCC)
  • Reports of impacts on the electricity business at the international level
  • Trends in climate change policy formulation at national and international levels
  • Trends and expectations on climate change of investors and stakeholders

GPSC convenes an internal risk identification meeting annually to review, monitor, and consider emerging risks.

GPSC considers both the severity and likelihood of physical impacts based on a climate change model known as the “Representative Concentration Pathway (RCP),” which simulates greenhouse gas emissions events referenced in the IPCC’s fifth assessment report and consists of four scenarios: RCP2.6, RCP4.5, RCP6, and RCP8.5, each showing the different levels of CO2 concentrations affecting radiation on the Earth’s surface. These scenarios are forecast results of the implementation of the climate change policies of various countries from 2000 to 2100.

GPSC has chosen scenarios RCP2.6, RCP4.5, RCP6.0, and RCP8.5 in considering the severity and likelihood of impacts and annually assesses potential climate-induced financial losses through risk review meetings. Furthermore, as scenarios are also required for the risk severity and likelihood assessment, GPSC has chosen Thailand’s Nationally Determined Contributions (NDCs) as a reference case.

GPSC has summarized the results of the physical and transitional risk assessment for the years 2021, 2027, and 2030, with the specification of risk issues, impacts, countermeasures, and adaptation as follows:

Risks with high to very high levels of severity and frequency in 2021:
  • Increased extreme weather events
  • Drought
  • Rising average global temperatures
Risks with high to very high levels of severity and frequency in 2027:
  • Increased extreme weather events
  • Drought
  • Rising average global temperatures
  • Changes in consumer behavior

  • Adjust the business model to meet customer needs with a diverse range of services and products.
  • Conduct feasibility studies on a transition to smart grid systems in Thailand.

GPSC has studied internal carbon pricing (ICP), which assigns a monetary value to greenhouse gas emissions produced by an organization, in order to drive climate change actions in the organization, including preparing for climate change risks and impacts, setting greenhouse gas emissions reduction targets, and using carbon pricing as a basis for making investment decisions and a mechanism for driving long-term low-carbon operations. GPSC has been selected as one of the first six companies to receive technical support from the Thailand Greenhouse Gas Management Organization (Public Organization) and has cooperated with the World Bank in capability development as well as in establishing and applying internal carbon pricing (ICP) mechanisms appropriate to the context and strategies of the organization, while also fostering environmentally friendly investments. At present, GPSC’s guidelines involve the following three activities:

The use of “shadow prices” to assess the risks and impact of carbon pricing on the future earnings of the company

The use of shadow prices as one of the criteria for investment decisions (CAPEX)

The use of carbon pricing as one of the criteria for decision related to operating costs (OPEX)

GPSC has appointed a committee and a task force responsible for conducting internal carbon price projects and investments in GHG emission reduction, with the objective of planning and monitoring the adoption of internal carbon pricing to ensure suitability for the business operations. They are also tasked with assessing the financial situation and green financing guidelines as well as offering opinions on the development of operational guidelines to further strengthen its capabilities and in-depth knowledge of carbon pricing and other financial instruments to maximize effectiveness.

Additionally, GPSC has formulated a 10-year internal carbon pricing adoption plan, beginning in 2020, and developed implementation guidelines suitable for the established timeframe. GPSC seeks to apply three internal carbon pricing mechanisms, namely the price determined by the amount of money an organization spends for reducing greenhouse gas emissions (implicit price), the hypothetical greenhouse gas price (shadow price), and the determination and collection of greenhouse gas emission fees of each business unit in the organization (internal carbon fee/ internal trading system), in order to make tangible contributions and cover all emission scopes, as detailed below.

Short-Term (2021-2022) Long-Term (2023-2030)

GPSC has utilized the shadow price to supplement its decision for new investments that cover Scope 1 and Scope 2 emissions through collaboration with other business groups related to the electricity business. In 2022, the Strategic Investment Management Committee (SIMC) approved the use of internal carbon fees as a component in the calculation of the return on investment of conventional projects. In addition, GPSC has planned to develop tools to expand the data collection of its GHG emissions and marginal abatement cost curves to strengthen its ability to recover from the impacts of climate change and achieve its long-term emission reduction goals.

In 2022, GPSC participated in the Low Carbon and Sustainable Business (LCSB) assessment, conducted by the Greenhouse Gas Management Organization (Public Organization), in which participating business organizations were assessed on their GHG management and reduction efforts in accordance with Thailand’s sustainable development goals. GPSC received an excellence award for the third consecutive year and met low-carbon and sustainable business organization criteria in three categories: 1) low-carbon and sustainable environmental development, 2) low-carbon and sustainable economic development, and 3) low-carbon and sustainable social development.

GPSC also was selected in 2022 as one of the four companies to receive an “excellent” rating for their outstanding climate actions, including GHG emission reduction, life cycle assessments (LCA), carbon footprint product (CFP) development, participation in the Thailand Voluntary Emission Reduction Program (T-VER), supporting sustainable development goals, and the achievement of the zero-waste to landfill target.

GPSC has joined and has been selected as a member of the Thailand Carbon Neutral Network (TCNN) committee in collaboration with Climate Neutral Now under UNFCCC to promote cooperation between the government, the private sector, and the local/community sector in order to expand GHG emission reduction. The objective is to foster sustainable growth in a climate-friendly society and achieve net zero greenhouse gas emissions in accordance with the intent of the international community, as evidenced in the targets of the Paris Agreement and Thailand’s climate goals. This cooperation will create demand for carbon credits from the T-VER project, which will contribute to the expansion of the domestic voluntary carbon market as well as enhance liquidity. GPSC foresees that the participation in this program will bring benefits through the exchange of knowledge between members with regard to studies of feasibility, potential, and preparedness; operational guidelines; and the declaration of its corporate carbon neutral targets, as well as bolster joint benefits in terms of sustainable development thanks to GHG reduction activities and projects, particularly at local and community levels, carried out in cooperation with private businesses in the network, such as joint support for nature-based activities that help absorb carbon dioxide.

GPSC has also joined the Carbon Market Club and the RE100 Thailand Club, marking an important step for the company as an energy business in promoting GHG reduction activities and demonstrating its corporate social responsibility, thus underlining its readiness to transition to a low-carbon society and acheive net zero GHG emissions. Through these memberships, GPSC has engaged in discussions with other member organizations about the trading of carbon credits and international renewable energy certificates (I-RECs), and has stayed up-to-date on the latest updates, registration processes, relevant climate change-related policies, and how to join the United Nations Global Compact (UNGC). GPSC has also pledged to develop sustainable operation policies and further prioritize corporate social responsibility to ensure its operations benefit society. This is in line with the 10 international principles of human rights, labor, the environment, and anti-corruption efforts, particularly Principles 7, 8, and 9, which pertain to the environment, for which GPSC has developed operational plans and directions specifically to drive the net zero GHG emission target in order to truly address the problem of climate change.

Furthermore, GPSC has lent support to the Thailand Business Council for Sustainable Development (TBCSD), founded by the World Business Council for Sustainable Development (WBCSD) to promote sustainability among businesses and provide a platform for private organizations to share knowledge and drive sustainable development in collaboration with the government and other agencies, with emphasis on the development of policies that foster business competitiveness and public awareness of environmental issues, including climate change.

1. Suppliers

GPSC has established a green procurement policy and a sustainable supplier management policy, specifying qualifications for supplier selection, such as the use of clean energy in the operating area, production efficiency, as well as proper waste management and recycling. All suppliers providing products or services to GPSC are required to sign a form to acknowledge and pledge to comply with the requirements in order to encourage all suppliers to implement climate change management and demonstrate environmental responsibility and to collect data beneficial to GPSC’s annual report of operating results. In addition, GPSC hosts Supplier Day annually to present vital information to suppliers and share its knowledge and experience on sustainable development in order to promote their sustainable development, particularly regarding climate change management./p>

2. Customers

As energy demand shifts farther towards renewable energy, GPSC has been expanding its renewable energy production capacity consistently to meet consumer demand in pursuit of a low-carbon society. In 2021, the company installed over 873.84 KWp of rooftop solar power generation systems for customers, reducing Scope 2 emissions by approximately 725 tonsCO2eq per year. GPSC also offers floating solar installation services, which not only meet customer needs but also bolster customer satisfaction thanks to the fact that a floating solar power generation system can maximize space utilization and reduce the evaporation rate in the water reservoir. This system can reduce greenhouse gas emissions by up to 830 tonsCO2eq per year. Recognizing the importance of providing renewable energy options to customers, GPSC has set a target to reduce greenhouse gas emissions by over 1,555 tonsCO2eq per year.

3. Partners

GPSC seeks to prioritize and promote open innovation in collaboration with its partners, focusing on combining internal and external bodies of knowledge to develop electricity storage systems, which are key components in the installation of renewable energy systems and critical to the efficiency optimization of such systems. In addition, GPSC is committed to becoming a leader in energy storage system (ESS) production, and its primary objective is to deliver ESSs to domestic and overseas renewables-based power plants to meet the rising demand for renewable energy among other businesses.

In 2022, GPSC established the Carbon Capture, Utilization and Storage (CCUS) Technology Development Consortium (CCUS Consortium) in collaboration with the Bio-Circular-Green-economy Technology & Engineering Center (BCGeTEC) of the Department of Chemical Engineering, Faculty of Engineering, Chulalongkorn University; seven companies across different industries; government agencies; the Thailand Greenhouse Gas Management Organization (Public Organization), an organization that plays a vital role in providing Thailand’s climate change knowledge and data; as well as other organizations in the network. CCUS Consortium has four primary objectives: 1) foster a cooperative network between academic and industrial sectors and government agencies, 2) address public concern over climate change, 3) accelerate CCUS technology development, and 4) drive research towards actual applications. Since 2021, CCUS Consortium has conducted three projects as follows:

  1. Research on CCUS technology development and application to Thailand’s core industries
  2. Building international collaboration on the conversion of carbon dioxide into various products, such as methanol and methane, based on hydrogen produced with a membrane-assisted zero-carbon process
  3. Development of technology with a high technology readiness level (TRL)

Furthermore, GPSC has conducted a feasibility study on the application of PTT Group’s carbon capture and storage (CCS) technology (PTT Group CCS Hub Model) in collaboration with five companies under PTT Group with the objective of studying the feasibility of comprehensive CCS technology application in support of PTT Group’s GHG emission reduction efforts in Rayong and Chonburi. The project will serve as a vital model for scaling up CCS application to the national level and involves the study of two types of carbon capture and storage:

  1. Offshore carbon capture and storage for developing Thailand’s first pilot project and creating opportunities for future CCS applications
  2. Offshore carbon capture and storage for studying carbon capture and transportation methods and seeking opportunities for on/nearshore CCS applications
4. Communities

In collaboration with PTT Group, GPSC has developed a smart farming project with the goal of promoting job creation for local residents in communities and exchange of knowledge and experience by the company’s employees and of supporting the installation of renewable energy systems in water pumping and electrical systems in plantations in order to reduce GHG emissions in the agricultural sector. The project also seeks to foster skills and capabilities beneficial to residents in remote areas and to give them access to new renewable energy technologies. In 2022, GPSC also carried out its reforestation and seagrass planting, which could absorb carbon dioxide by 590 tonsCO2eq, with a long-term target of expanding the reforestation area to 2,000 rai by 2030.
