The Electricity Generating Authority of Thailand (EGAT) has launched a tender for the construction of a 205 MW floating solar-hydro hybrid project at the Bhumibol Dam, which is the largest arch dam in Southeast Asia, currently equipped with a 779 MW hydropower facility.
The tender is aimed at developing a hybrid project in the Sam Ngao district of western Thailand at the Bhumibol Dam. According to EGAT’s website, this dam is the highest and largest arch dam in Southeast Asia, hosting a 779 MW hydropower plant.
The project involves the construction of a 205 MW crystalline silicon solar power plant, which will include a floating photovoltaic system, anchoring and mooring systems, a 33 kV electrical system, transmission lines, control and monitoring systems, as well as related software.
Details from the tender indicate that the selected developer will be responsible for designing, procuring, manufacturing, delivering, insuring, managing, constructing, installing, testing, commissioning, and providing on-site training.
Interested applicants must purchase the tender documents from EGAT at a cost of $1,000 or 30,000 Thai Baht (approximately $885), which is non-refundable. The project will be financed by the EGAT fund, and the application deadline is set for July 14, 2025.
In July 2024, EGAT initiated another tender for a hybrid hydro and floating solar project that includes 182 MW of solar capacity. Additionally, another project featuring a 24 MW floating solar array commenced commercial operations in March 2024.
EGAT’s development of hybrid solar-hydro projects aligns with Thailand’s power development plan, which aims to establish 16 floating solar projects across 9 EGAT dams, with a total capacity exceeding 2.7 GW.
