Generating Capacity
         Lamtakong pumped-storage hydropower plant is situated 350 meters underground. The total capacity will be 1,000 MW. The project is divided into 2 phases.
         - Phase 1
         There has been an installation of two pumped-storage generating units, and each has the generating capacity of 250 MW.
         - Phase 2
         Two more pumped-storage generating units will be installed, and each has the generating capacity of 250 MW.

Background
         The northeastern part of Thailand covers a large area and is the most populated region of the country. The expansion of towns during the past years has increased the higher demand for electricity than the available capacity of power generation in the region. Therefore, the Electricity Generating Authority of Thailand had to consider the construction of the first reversible pumped-storage hydropower plant which is the modern technology in power generation in this region.
         The power plant construction had started in 1994 and was completed in 2004. On July 17, 2009 the power plant was named by His Majesty King Bhumibol Adulyadej as “Lamtakong Jolabha Vadhana Power Plant” meaning “Lamtakong Power Plant is the place where the light is created by means of water.”
         On 13 June 2013, Her Royal Highness Maha Chakri Sirindhorn represented His Majesty King Bhumibol Adulyadej in performing the opening ceremony of the power plant. Lamtakong Jolabha Vadhana Power Plant is the last power plant in the reign of His Majesty King Bhumibol Adulyadej which has received the auspicious name by the King.

Lamtakong Wind Turbines
         As it has been discovered later that the average wind speed over the upper reservoir of Lamtakong Jolabha Vadhana Power Plant is averagely 5-6 meters per second suitable for the development of wind turbine farm, two 1,250 kW wind turbines totaling 2,500 kW of installed capacity were constructed by EGAT. Later, the additional 12 wind turbines (two MW each), have been installed to make the total generating capacity of 26,500 kW.

EGAT Learning Center
         The learning center at Lamtakong which is under construction will exhibit electricity generation technologies such as pumped-storage and wind power as well as storage system for renewable power. The electricity supplied to the building comes from the 12 wind turbines through hydrogen fuel cell system, while the oxygen produced from the system will be circulated in the leaning center building as well.
