Pak Mun Dam, a significant hydroelectric power generation facility in Thailand, ranks 94th among the country's 293 plants with a capacity of 136 MW. This facility constitutes approximately 0.14% of Thailand's total energy capacity of 99,456 MW. Commissioned in 1994, Pak Mun is an essential contributor to the national grid, utilizing the power of flowing water to generate electricity through advanced hydro technology. The dam is in proximity to other hydro plants, including the Pak Mun plant, which shares its capacity of 136 MW, and several smaller facilities like Tha Thung, Sirindhorn Dam, and Khan Rai - BSP Solar Power Plant, each contributing to the overall energy mix in the area. Thailand's energy profile is heavily influenced by natural gas, but hydroelectric power plays a vital role in balancing the energy supply, especially during peak demand periods. The Electricity Generating Authority of Thailand operates Pak Mun, reflecting the country's focus on harnessing renewable energy sources. The strategic positioning of Pak Mun allows it to support local energy needs while minimizing environmental impact, as hydroelectric power is one of the cleanest forms of energy generation. As the nation continues to explore sustainable energy options, Pak Mun Dam represents a forward-looking example of how hydroelectric facilities can contribute to energy stability and environmental sustainability, helping Thailand move towards a greener future while meeting the demands of its growing economy.
