The Imboulou Hydroelectric Plant is a major power generation facility located on the Léfini River, approximately 215 kilometers north of Brazzaville. With an installed capacity of 120 megawatts, provided by four 30-megawatt turbines, it is one of the most significant energy projects in the Republic of the Congo. The plant was constructed by the China Machinery Engineering Corporation (CMEC) and was officially inaugurated in 2011 to address the country's chronic electricity shortages. The dam structure creates a reservoir that regulates the flow of the Léfini River, ensuring consistent power production throughout the year. Electricity generated at Imboulou is transmitted to the capital and the national grid via a high-voltage 220-kilovolt transmission line. The project has played a transformative role in stabilizing the power supply for industrial and domestic consumers in the southern and central regions. It stands as a testament to the country's efforts to harness its abundant water resources for sustainable development.
