Summarize this article for a 10 year old
The Xayaburi Dam is a run-of-river hydroelectric dam on the Lower Mekong River, approximately 30 kilometres (19 mi) east of Sainyabuli (Xayaburi) town in northern Laos. Commercial operation of the dam started in October 2019.[3][4] The main purpose of the dam is to produce hydroelectric power, 95% of which is to be purchased by the Electricity Generating Authority of Thailand (EGAT).[5] The project is surrounded in controversy due to complaints from downstream riparians and environmentalists. Preliminary construction began in early-2012, but work on the dam itself was suspended shortly thereafter due to complaints from Cambodia and Vietnam downstream.[6] After making modifications to the dam's design, Laos started construction with a ceremony on 7 November 2012.[7] The Xayaburi Dam is the first of the 11 dams planned on the lower Mekong.[8]
