The Electricity Generating Authority of Thailand (EGAT) has invited bids to develop a 280 MW floating solar project at the Srinagarind Dam, Si Sawat district, in Thailand. EGAT’s fund will finance the project.

Bids must be submitted by December 16, 2025. Bids will be opened on the same day.

The bid document can be purchased until September 26, 2025.

Bidders must submit a bid security of ฿358 million (~$10 million).

The scope of work covers the design, procurement, manufacture, fabrication, shop tests, construction, installation, testing, and commissioning of the floating solar project.

It also includes providing insurance, project management, project guarantee, and equipment.

Selected bidders must set up the anchoring and mooring system, 33 kV electrical system and transmission lines, and control and monitoring system for the floating solar project.

The project must utilize double-glass crystalline silicon modules supplied by solar module manufacturers with a production capacity of at least 5,000 MW/year. The manufacturers must also have been included in the latest revision of BloombergNEF’s Tier 1 Manufacturer List.

Successful bidders must use 1,500-volt solar string inverters from manufacturers who have had a production capacity of at least 4,000 MW/year in the past two years.

Additionally, the solar string inverter manufacturer must have designed and manufactured solar string inverters for at least one solar project with a minimum capacity of 30 MW. This project must have been operational for at least one year.

They must also procure high-density polyethylene (HDPE) floaters for the project from suppliers who have designed and manufactured such floaters for at least one floating solar project with a minimum capacity of 8 MW.

Bidders must have conducted project management for at least one solar project with a minimum output of 20 MW.

Thidade Eiamsai, Deputy Governor at Power Plant Development and Renewable Energy of EGAT, said that the Srinagarind Dam floating solar project will be commissioned in 2028.

The project will share the main infrastructure and equipment with an existing hydropower project.

The project is part of Thailand’s Power Development Plan for 2018-2037, which aims to develop floating solar projects on EGAT’s dam reservoirs nationwide, to achieve a total generating capacity of 2,725 MW by 2037.

In 2024, the U.S. Department of Commerce announced its preliminary affirmative determinations in the anti-dumping duty investigations of crystalline photovoltaic cells, whether or not assembled into modules, from Thailand, and three other southeast Asian nations.
