The Generating Authority of Thailand(EGAT) has confirmed that a 24 MW hydro floating pv system, located at Ubol Ratana Dam in Khon Kaen province in northeastern Thailand, has started commercial operation.
The hydro floating pv system integrates solar energy, hydropower and a Solar Battery Storage (BESS). It harnesses solar energy in the day and hydropower at night, while the BESS allows continued electricity generation during the transition between the two. EGAT said an energy management system and weather forecast system have been incorporated to enhance stability of the electricity generation system.
The authority has collaborated with Thailand-based Fisheries Research Center to promote the conservation of aquatic animal species in the area. Fishery is integral to the quality of life of people living in the vicinity of the dam, with many millions of fish released into the reservoir annually.
EGAT said the solar panels, fixed on floating solar mount which cover less than 1% of the reservoir's total surface area, are installed in a way that allows sunlight to penetrate the water surface without impacting the underwater ecosystem. It noted that it plans to develop a solar-powered shrimp farm in the area, acting as a learning centre so communities can generate income and achieve self-reliance.
The Ubol Ratana Dam project is EGAT's second floating solar hybrid project developed in accordance with Thailand's Power Development Plan. The authority is planning to develop 16 hydro floating pv system across nine of its dams with a total installed capacity of 2,725 MW.
According to the International Renewable Energy Agency (IRENA), Thailand deployed 3,065 MW of solar by the end of 2022. The country expects renewable energy to constitute more than 50% of its power generation mix by 2037.
