The Electricity Generating Authority of Thailand (EGAT) is forging ahead with its ambitious plan to develop floating solar power plants, launching the first phase of a 50-megawatt, floating solar project at Vajiralongkorn Dam in Kanchanaburi Province. The bidding process for interested contractors is now officially open and will run until 20 June.

The initiative is part of EGAT’s broader strategy to increase the share of clean energy in Thailand’s power generation mix and advance its commitment to carbon neutrality by 2050 and net-zero greenhouse gas emissions by 2065.

Mr. Thidet Eiamsai, Deputy Governor for Power Plant Development and Renewable Energy at EGAT, said that this floating solar installation will produce electricity from photovoltaic panels mounted on floating platforms across the dam’s reservoir. This project, referred to as Vajiralongkorn Floating Solar Power Plant Phase 1, is expected to begin commercial operation by 2027.

The development is part of Thailand’s Power Development Plan 2018–2037 (PDP2018 Revision 1) and its forthcoming updated energy roadmap. Under this plan, EGAT aims to deploy a total of 2,725 MW of floating solar power capacity nationwide by 2030. These projects will be built on the surface of EGAT-managed reservoirs across the country, leveraging existing hydropower infrastructure to minimise costs and optimise energy output.

This hybrid model, integrating solar with existing hydroelectric facilities, offers cost-effective power generation with reduced environmental impact. By using shared infrastructure and available water surfaces, EGAT can significantly lower production costs, which in turn benefits consumers with more affordable electricity.

EGAT’s floating solar initiative is also expected to stimulate private sector participation in Thailand’s clean energy transition. Interested companies can purchase bidding documents from now until 20 June 2025, with the envelope opening scheduled for 16 September 2025.
