Generating Capacity
         The power plant houses three 12 MW generators, totaling 36 MW of generating capacity.

Sirindhorn Solar Cell
         Sirindhorn Solar Cell Project was among the renewable energy projects included in the Power Development Project (PDP 2004) (B.E. 2547-2552). The construction commenced in 2007 and was completed in 2009.
         The power plant occupies an area of approximately 25 rai. The number of 7,476 solar cell panels are used with the total installed capacity of 1.012 MW. Two systems of solar cell panels have been installed namely the fixed installation and the solar weighted tracking system installation. For the latter system which is initiated by EGAT, solar panels are capable of moving along the orbit of the sun from morning to evening to generate electricity throughout the day. This system is regarded as an innovation developed by EGAT researchers.
         The electricity generation by solar cells can replace the use of 348,000 liters of bunker oil per year, reduce the carbon dioxide emissions of 851.1 tons a year, and provide carbon credit up to 701 tons amounting to approximately 112,000 Baht. The Sirindhorn Solar Cell Power Plant is the first project in Thailand which has provided carbon credit in compliance with the standard of the United Nations Framework Convention on Climate Change (UNFCCC).

         Being an important multi-purpose dam in the northeastern part of Thailand, the construction of Sirindhorn Dam started in June 1968 and was completed in 1971. Sirindhorn Dam was built across the Lam Dome Noi River in the area of Kaeng Sae Noi, Chong Meg Sub-district, Piboon Mangsahan District, Ubon Ratchathani Province.
         At the completion of the construction in 1971, the name Sirindhorn was given to the dam with the royal permission. The opening ceremony was performed by His Majesty King Bhumibol Adulyadej on November 27, 1971. Later on, according to the decision of the National Energy Policy Committee in 1972, Sirindhorn Dam has been under the responsibility of the Electricity Generating Authority of Thailand (EGAT) until today.


         The uniqueness of the accommodation at Sirindhorn Dam is its location that faces the reservoir. The visitors can enjoy the view and fresh air during their rest.

         Reun Dome Noi has been guaranteed by “Clean Food Good Taste” standard of Sirindhorn District Health Authority. The place is a large space beside the reservoir with full facilities. The recommended menus are comprised of fish caught from the reservoir.

Golf Course
         The golf course at Sirindhorn Dam is suitable for those who love exercise and natural beauty.

Recreational Park
         Sirindhorn Garden was built to commemorate the 36th birthday anniversary of Her Royal Highness Princess Maha Chakri Sirindhorn. It occupies an area of about 40 rai and has been designed to be a forest garden similar to the original condition. The garden comprises a botanical garden, fountains, rest pavilions, plants and flowers in purple color which represents the color of the Princess’s birthday. The uniqueness of this park is the sculpture of three elephants playing music placed in the middle of the fountain. Each elephant plays xylophone, fiddle, and flute which are the favorite Thai musical instruments of Her Royal Highness Princess Maha Chakri Sirindhorn.
