Sirinthon (สิรินธร)

Name of the second daughter and third child to King Bhumipon and Queen Sirikit. Born at Phra Tihnang Amphon Sathaan in Dusit Palace, on 2 April 1955. Her full name and royal title are Somdet Phra Chao Look Teh Chao Fah Sirinthon Thep Rattana Rachasudah Kittiwattanah Dunlasohpahk (สมเด็จพระเจ้าลูกเธอเจ้าฟ้าสิรินธรเทพรัตนราชสุดากิติวัฒนาดุลโสภาคย์), whilst the King later changed her ceremonial title into Somdet Phrathep Rattana Rachasudah Sayaam Boromarachakumarih (สมเด็จพระเทพรัตนราชสุดาฯ สยามบรมราชกุมารี). Having been born on a Saturday, the princess' personal flag (fig.) consists of a purple background, with her initials, i.e. a ส (s) in blue and a ธ (t) in yellow (or sometimes in white), underneath a golden (orange) crown (fig.). Whereas the crown, which is smaller than those of the King and Queen, refers to her royal status as a princess, the blue and yellow of her initials are the colours of the days on which the queen and king respectively were born, i.e. blue for Friday and yellow for Monday (see sih prajam wan), which could indicate that she is their offspring, though the colour of the ธ (t) is sometimes left white. The day of her birth, the king had been scheduled to present words to graduates of the Police Academy (fig.), but appointed prince Wiwattanachai to officiate in his place. Both the Sirinthon Dam and the district in which the dam is located, in Ubon Ratchathani province, are named after her (fig.). On the artificial lake created by the dam, which is fed by the Lam Dom Noi River, the Electricity Generating Authority of Thailand (EGAT) in November 2021 begun generating power from its hydro-floating solar hybrid farm project, which is said to cover an area the size of about 70 football fields and purportedly the largest hydro-floating solar farm in the world. Whereas 145,000 solar panels harness power from the sun during the day, at night 3 turbines convert energy from the flowing water. The project is part of the country’s push to achieve carbon-neutral status by 2050. Her first name in Roman script is also often transliterated Sirindhorn. 回
