The Electricity Generating Authority of Thailand (EGAT) has officially launched the tender process for a 140-megawatt (MW) floating solar farm on the reservoir of Srinagarind Dam, marking the third major installation in its ambitious Hydro-Floating Solar Hybrid project series. This initiative is a cornerstone of Thailand’s strategy to enhance its renewable energy capacity and achieve its national carbon neutrality goals.
Strategic Expansion at Srinagarind Dam
Set to be integrated with the dam’s existing 720 MW hydropower plant, the new floating solar facility aims to create a stable, hybrid power generation system. This project follows the successful commissioning of EGAT’s first 45 MW floating solar plant at Sirindhorn Dam and a second 24 MW facility at Ubol Ratana Dam, which became operational in 2024. The tender for the Srinagarind Dam project was accelerated under the Ministry of Energy’s “Quick Big Win” policy, with bid submissions closing on July 3, 2024, and the official bid opening scheduled for August 14, 2024.

Advancing Thailand’s National Energy Goals
This project is a critical component of Thailand’s Power Development Plan, which outlines a target of installing 2,725 MW of floating solar power across 16 projects at nine different dams by 2030. By leveraging existing reservoirs, the country can significantly boost its green energy production without consuming valuable land resources. The initiative directly supports Thailand’s long-term commitments to achieving Carbon Neutrality by 2050 and Net Zero Emissions by 2065.

The combination of hydropower with floating solar panels offers unique advantages. Hydropower can be dispatched during peak hours or when solar generation is low, while solar power can operate during the day, optimizing the use of the existing transmission infrastructure and ensuring a more reliable energy supply. Furthermore, the water’s cooling effect can increase the efficiency of the solar panels by up to 10% compared to ground-mounted installations, according to the World Bank, while the panel coverage helps reduce water evaporation.
A Roadmap for a Sustainable Future
The comprehensive scope of the Srinagarind Dam project includes the design, supply, construction, and commissioning of the floating photovoltaic systems, anchoring, and electrical infrastructure. This signifies a major step in building a sustainable and technologically advanced renewable energy fleet. As Thailand continues to expand its green portfolio, projects like this reinforce its position as a regional leader in the transition to clean energy, paving the way for enhanced energy security and a more sustainable society.
