Laos's largest hydroelectric project, Nam Theun 2 Dam (NT2), began operation in March 2010. The scheme diverts water from the Nam Theun, a tributary of the Mekong River, to the Xe Bang Fai River, enabling a generation capacity of 1,070 MW, from a 350 m (1,148 ft) difference in elevation between the reservoir and the power station. At the time of signing in 2005, NT2 was the largest foreign investment in Laos, the world's largest private sector cross-border power project financing, the largest private sector hydroelectric project financing, and one of the largest internationally financed IPP projects in Southeast Asia. The dam also marked a return by the World Bank to funding large-scale infrastructure, after a decade-long hiatus. The dam also exports energy to neighboring Thailand, thus is important to the regional economy. Along with Khammouane and Savannakhet provinces, it is one of the main tobacco producing areas of Laos, and also one of the main producers of sugar cane and oranges.
