As part of this 15-year PPA, GreenYellow will deploy self-consumption photovoltaic systems on the rooftops of 15 Dohome stores, with a total capacity of 10.5 MWp, combined with battery storage systems totaling 13 MWh, equivalent to the annual consumption of + 5,000 Thai inhabitants. Once operational, the system will reduce CO₂ emissions by +6,700 tons per year. This combination of technologies makes it possible to respond to a critical double challenge for the retail sector: maximizing the self-consumption of green energy while securing the network.
In concrete terms, the addition of batteries (BESS) will allow Dohome to:
- Smooth peak consumption (peak shaving) to reduce peak demand costs.
- Ensuring the operational stability of the stores via backup power.
- Reduce the overall electricity bill by 25 to 30%.
A sustainability strategy at the heart of the partnership
Salintip Ruangsutthiphap, Deputy Director of Accounting, Finance, and Business Support at Dohome, said: “The signing of this PPA with GreenYellow fully aligns with our sustainability policy, which aims to balance business growth with social responsibility and environmental commitment, including reducing greenhouse gas emissions and transitioning to a low-carbon business model. Collaborating with a global leader like GreenYellow, recognized for its end-to-end expertise in solar energy and battery storage, strengthens our ability to achieve our sustainability goals. Beyond significant energy savings, this partnership lays the foundation for positioning Dohome as a ‘green retailer’ actively contributing to the national net-zero target.”
This project is based on GreenYellow's CAPEX-free model, which carries out the study, finances, designs, installs and operates the entire system over the entire contract period.
Jeerapa Kongswangwongsa, Commercial Director of GreenYellow Thailand, emphasized: “This partnership with Dohome represents a major milestone for Thailand’s retail and building materials sector. It demonstrates our ability to deploy innovative large-scale solar and battery storage solutions and to transform how energy is used in this industry. We are proud to contribute to Dohome’s sustainability strategy while reinforcing our ‘Solar Frontiers’ vision, which aims to expand the adoption of clean energy across all sectors.”
A model for the entire industry
The signing of this PPA marks a significant shift in Thailand’s retail and building materials sector, where companies are increasingly adopting clean energy in response to the government’s accelerated net-zero target, now advanced from 2065 to 2050.
Thanks to its scale and technological integration, this project will serve as a reference model, encouraging other operators in the sector to seriously invest in clean energy solutions and contribute meaningfully to national greenhouse gas reduction efforts. The agreement also highlights the sector’s dual mandate: reducing operating costs while minimizing environmental impact.
Work on the 15 branches will begin in the 4th quarter of 2025 for full commissioning scheduled for the 2nd quarter of 2026.
