Thailand Tenders 280 MW AC Floating Solar Capacity

The Electricity Generating Authority of Thailand (EGAT) has invited interested bidders for a minimum of 363.95 MW DC and a maximum of 364 MW DC (280 MW AC) floating solar PV capacity for the Srinagarind Dam in Kanchanaburi Province. 

The Srinagarind Dam Floating Solar Project 3 (SNR-PV3) is part of the country’s Power Development Plan 2018-2037 Revision 1 (PDP2018 Revision 1) under which EGAT targets to deploy 2.725 GW floating solar capacity on its dam reservoirs by 2037 (see Thailand Plans World’s Largest Floating PV Capacity). 

The broad scope of work ranges from design, procurement, manufacture, fabrication, project construction, installation, testing, and commissioning, among other tasks. EGAT will finance the project from its own funds. 

It seeks bids from developers who will source double-glass crystalline silicon PV modules from only those tier I manufacturers that are listed in the latest BloombergNEF’s manufacturers list. Such suppliers must have at least 5 GW annual production capacity of such modules. Similarly, inverters must be purchased from manufacturers with at least 4 GW annual production capacity.

The floating solar power plant will share the transmission infrastructure of the existing hydropower plant on site to ensure lower project costs. EGAT targets commercial operations of this project in 2028. 

Bidding documents will be available to purchase from August 25, 2025, to September 26, 2025, on EGAT’s website. Bids are tentatively scheduled to be opened on December 16 this year. 

Srinagarind Floating Solar project 1 had 140 MW and project 2 had 280 MW capacity as per the agency’s plans revealed in 2019. In March 2025, EGAT launched a 205 MW DC/158 MW AC floating solar tender for Bhumibol Dam Reservoir (see Thailand Launches 205 MW Floating Solar Tender).
