Bangkok, June 18, 2025 – GreenYellow (Thailand) Co., Ltd., a global investor and operator in solar energy production (Solar PPA) and energy efficiency, has joined forces with Thai Airways Public Company Limited, Thailand's national airline. This collaboration was formalised through the signing of a Power Purchase Agreement (PPA) to invest in, install, operate, and maintain a comprehensive solar power generation system, including both rooftop and carport installations, at Thai Airways’ Head Office. Under the 20-year agreement, the system will have a total installed capacity of 999.7 kilowatt-peak (kWp) and is expected to generate 1,359 megawatt-hours (MWh) of electricity annually, reducing carbon dioxide emissions by approximately 589 tonnes per year. This marks a significant step, underscoring Thai Airways’ commitment to driving environmentally friendly and sustainable operations.
This solar rooftop and carport project aligns with Thai Airways’ sustainability management policy, which emphasises conducting business under the Circular Economy principle to create sustainable value. The company prioritises transparency, good governance, and responsibility towards society and the environment. Key objectives include minimising environmental impact, promoting the efficient use of resources, reducing greenhouse gas emissions, and supporting the transition to clean energy. Additionally, Thai Airways is committed to enhancing the quality of life for employees, communities, and all stakeholders, while adhering to strict governance principles to ensure long-term transparency and sustainability.
Ms Chuntarica Jotikasthira, Chief Human Resource Officer, Thai Airways Public Company Limited, stated: “Thai Airways is strongly committed to being a leader in propelling the Thai aviation industry towards a sustainable energy era. This partnership with GreenYellow is therefore a tangible step towards achieving this vision. This solar rooftop and solar carport project at our Head Office will serve as a model for significantly enhancing the organisation’s energy efficiency. The clean energy produced will be utilised to power all operations at the Head Office buildings, while tangibly reducing our reliance on fossil fuels and cutting greenhouse gas emissions by 589 tonnes per year. This aligns with the Net Zero goals of the International Civil Aviation Organization (ICAO) and our policy to create a sustainable future. This collaboration not only directly benefits Thai Airways but also serves as a crucial driving force to inspire other businesses to adopt renewable energy for a better world.”
Mr Frank Glück, Chief Executive Officer of GreenYellow Thailand and Asia, commented on the collaboration: “Our partnership with Thai Airways, the national airline and an industry leader, represents a significant milestone for GreenYellow in expanding our role into the aviation sector – one of the key industries rapidly accelerating towards sustainability. We are proud to offer comprehensive clean energy solutions under our proven Build-Own-Operate-Transfer (B.O.O.T.) model, which demonstrably helps large organisations reduce energy costs, increase efficiency, and tangibly cut carbon emissions. This collaboration not only reaffirms our commitment to supporting Thailand’s energy transition but also showcases the potential of solar energy to meet the demands of diverse industries. We are ready to be a trusted partner for Thai Airways and other leading organisations in transitioning to sustainable energy use and building a cleaner future.”
GreenYellow has consistently initiated and operated solar energy projects and energy efficiency solutions with leading organisations in Thailand, including Nestlé, Betagro, Tipco, and Unilever. This reflects the company’s success in driving clean energy adoption across Thailand’s industrial and commercial sectors, with a total installed capacity exceeding 200 megawatt-peak (MWp) and an annual reduction of over 150,000 tonnes of carbon dioxide emissions. This represents a significant contribution to advancing sustainable energy use among Thai businesses.
The expansion of GreenYellow’s collaboration into the aviation sector with Thai Airways further solidifies its role as a leader in solar energy, ready to support all industries in transitioning towards a low-carbon economy.
