EGAT expected to open Lam Takhong Hydro Power and Wind Power Plants and the learning center to the public; and would bring the biggest hydrogen fuel cell in South-East Asia to operation in the learning center.


          Mr. Ratanachai Namwong, Deputy Governor – Power Plant Development, revealed that EGAT was ready to open Lam Takhong Hydro Power and Wind Power Plants as well as the learning center, complying with the concept of developing power plant to be tourist attraction. It would open to the public by 2017 when all the mentioned development projects were completed. Interested people could visit to see the pumped storage hydro power technology which was Lam Takhong Hydro Power Plant, wind turbine, and power learning center. The students from the nearby schools of the power plant would be the tour guides for the visitors.

          The Deputy Governor said that inside the center, it would present various power generation technologies and domestic power situation. The information would be always up-to-date. The electrical power used in the building was from 12 wind turbines, each of which was 2 MW, through hydrogen fuel cell system. The electricity from wind turbine was used to separate water (H2O) to hydrogen and oxygen. The hydrogen would then be used to generate constant alternating current electricity used in the building, while oxygen would be circulated. The hydrogen fuel cell EGAT would use would be the biggest one in South-East Asia and was a part of EGAT’s research and development on power.

          EGAT expected that the combination between renewable energy and modern storage tools would be interesting and attract those who passed by the power plants. Apart from the various technologies used to show potential and limit of renewable energy and other power, there is also interesting information on domestic power situation.

          Lam Takhong Power Plant was the first and single underground plant in Thailand that had the smallest reservoir on the mountain top. The power plant used the power from the system during the low demand, which was after midnight until morning, to pump the water from the old reservoir and store in the new upper reservoir on Yai Tieng Mountain before releasing the water through the generator to generate electricity during the peak demand. It had the total capacity of 1,000 MW. The project was operated in 2 phases. The first phase was to set up the pumped storage generators 1 and 2 with 250 MW each. Their commercial operation date was in 2004. The second phase was to set up the pumped storage generators 3 and 4 with 250 MW each, and they would commercially operate in November 2018. They would enhance the power system in northeastern provinces and the nearby areas.

          On the upper reservoir, the wind speed was 5-6 meters per second. It was the potential point to develop the big wind turbine to be the model for other turbines in the future. EGAT had installed two wind turbines with the total capacity of 2.5 MW that commercially operated on March 16, 2009. They could generate 4.60 million units of electricity per year, replace the import of oil for 1.10 million liters per year, and reduce CO2 emission that was the cause of global warming for 2,300 tons per year.

          Moreover, EGAT implemented the Lam Takhong Wind Power Project Phase 2 in response to the Minister of Energy’s renewable energy strategy B.E. 2551-2565. The power development site was on Yai Tieng Mountain, the northern side of the Lam Takhong Hydro Power Plant’s upper reservoir, where there were 12 turbines with 2 MW each, contributing to the total capacity of 24 MW. They were expected for commercial operation in July 2017.
