EGAT Unveils 280 MWac Floating Solar Power Plant Project at Srinakarin Dam 3

Strategic Insights -

The Electricity Generating Authority of Thailand (EGAT) has initiated the 280 megawatt (MWac) floating solar power plant project at Srinakarin Dam 3, with bidding open from August 26 to September 26, 2025. This project is part of EGAT's strategic plan to develop clean energy power plants, with the aim of utilizing solar panels mounted on floating pontoons in the dam's reservoir, sharing the same structure and core equipment as existing hydropower plants, reducing electricity production costs and ensuring reasonable electricity prices. The project is designed to be environmentally friendly, with the use of solar panels installed at a slope to allow light to penetrate without impacting the environment and underwater ecosystems. This project is aligned with the Thailand Power Development Plan 2018-2037, Revision 1 (PDP2018 Revision 1), which aims to develop 2,725 megawatts of surface renewable energy capacity in EGAT's dams nationwide by 2037, supporting the country's goal of achieving carbon neutrality by 2050 and net-zero emissions by 2065 through concrete mechanisms supporting carbon dioxide emission offsets and avoidance.
