Who Are We

Founded in 2007 in France, the GreenYellow model is based on the fundamentals of enhancing the unused spaces of our clients by installing solar panels and focusing our development on green and local energy. Since then, we have expanded our expertise and become an energy partner for businesses and institutions, offering a wide range of solutions: solar power plants, energy efficiency, storage BESS, EV chargers, and more.

We operate under the BOOT model: Build, Own, Operate, and Transfer. We are investors and operators, helping our customers consume greener energy or less energy.

We have been operating in Thailand since 2015. In no time, we have developed a large portfolio of customers in both solar PPA (Power Purchase Agreement) and Energy Efficiency. With more than 170 MWp of signed projects, of which more than 100 MWp are already in operation, we have become a leader in energy transition in Thailand and Southeast Asia.
