Energy group GreenYellow, specialised in decentralised energy solutions, has formalised a power purchase agreement (PPA) with Dohome Public Company Limited. The deal involves the deployment of a hybrid energy system combining solar panels and battery storage across 15 of the Thai retailer’s stores.
A reference project for Thailand’s retail sector
With an installed capacity of 10.5 megawatt-peak (MWp) in photovoltaic solar and 13 megawatt-hours (MWh) of battery storage, the system is expected to generate 15.9 gigawatt-hours (GWh) of electricity annually. This output will be fully self-consumed by Dohome’s stores. The 15-year agreement represents the largest hybrid solar installation in the country’s distribution sector.
The solution integrates lithium-ion batteries to optimise the use of generated electricity and reduce consumption peaks. This peak shaving mechanism is expected to cut Dohome’s energy bills by 25 to 30 %, according to GreenYellow. Stored energy will also provide backup in the event of grid instability, ensuring operational continuity.
A zero-CAPEX energy model for the client
The entire system is based on GreenYellow’s capital expenditure-free (CAPEX-free) investment model, under which the group finances, designs, installs and operates the equipment. The project will be rolled out in phases starting in the fourth quarter of 2025, with full commissioning scheduled for the second quarter of 2026.
The contract comes amid regulatory changes in Thailand, where the national carbon neutrality target has been brought forward from 2065 to 2050. In this context, companies in the retail sector are increasingly adopting energy solutions to reduce grid dependence and improve operational efficiency.
High-tech project with regional impact
The Commercial Director of GreenYellow Thailand stated that the project marks a new step in the group’s strategy to roll out combined solar and storage solutions in high-energy-demand sectors. The scale and complexity of the system are expected to set a benchmark for future energy developments in the region.
Dohome operates large-format stores specialising in construction materials and home improvement products. With this partnership, the group becomes the first Thai distributor in its sector to adopt an integrated hybrid energy system at scale.
