- Thachang Green Energy Public Company Limited engages in the renewable energy business in Thailand, primarily generating and supplying electricity and steam from biomass and waste-to-energy sources. The company operates through two main segments, Biomass Power Plant Business and Waste Power Plant Business; it utilizes agricultural residues including empty palm bunches, palm fiber, chopped roots, and wood chips as primary fuels for electricity generation, while also providing waste management and construction services. Founded in 2011 and headquartered in Surat Thani, the company maintains operations centered in southern Thailand, particularly Tha Chang district, with a current installed capacity of approximately 76.6 megawatts across its facilities including the TGE, TPG, and TBP biomass power plants, of which 20.3 megawatts are sold to the Provincial Electricity Authority under long-term power purchase agreements. Targeting agricultural communities and local administrative bodies, Thachang Green Energy supports sustainable practices by converting organic waste into energy, contributing to waste reduction and eco-friendly power solutions in the utilities sector. In recent developments, the company plans significant expansion with seven new waste-to-energy power plants utilizing community waste, located in Sa Kaeo, Ratchaburi, Chumphon, Samut Sakhon, Chai Nat, Ubon Ratchathani, and Prachinburi, each with capacities of 8-9.9 megawatts and scheduled to commence operations between 2025 and 2026; these projects, developed under a build-own-operate model with 25-year contracts, are supported by long-term loan agreements entered in April and May 2025, aiming to boost revenue to 2.5 billion baht by 2026 and increase total capacity toward 200 megawatts by 2032, including explorations for waste-to-energy plants in the Asia-Pacific region.
