The World’s Largest Hydro-Floating Solar Hybrid Project in Thailand

Feb 2022

The Electricity Generating Authority of Thailand (EGAT) has moved forward with its policy of using clean energy and reducing carbon dioxide emissions with smart technology by deploying Siemens’s solutions in the world’s largest Hydro-Floating Solar Hybrid Project at Sirindhorn Dam, Ubon Ratchathani Province.  The project is the first installation of microgrid control, photovoltaic plant control and distributed energy optimization (DEOP) in Thailand. It has a solar power generation capacity of 45 megawatts and a hydroelectric capacity of 36 megawatts, capable of generating electricity from renewable sources day and night.

Siemens is responsible for installing, testing, and commissioning the Microgrid Control that works together with Photovoltaic Plant Control systems for the Hydro-Floating Solar Hybrid Project at Sirindhorn Dam. The company deployed and fully activated the Control systems in October 2021, and it has been in commercial operation since then. In addition, Siemens is installing DEOP, its cloud-based software for the optimization of distributed energy resources. DEOP’s capability to present real-time hybrid power distribution data on the dashboard helps EGAT manage power distribution more efficiently.

Operators can use a dashboard to monitor important parameters including the status of electrical equipment, electric power generation, weather measurement and electric power generation forecast. These solutions can properly address Egat’s needs for efficiently managing, forecasting, and supporting the commercial distribution of large amounts of electricity.

The energy ecosystem in Thailand is changing rapidly as technological innovations transform energy management. Thailand has stepped up to increasingly generate electricity with renewable energy by using integrated hybrid technology to meet the needs for decentralization, decarbonization, digitalization and smart electrification. This will enable the country to transition to electric power generation in a new context that requires energy stability and security amid economic, social, and environmental changes.
