The proposed dam is the fourth and largest of the Inga dams, {{convert|8|km}} from Inga-I, {{convert|7.3|km}} from Inga-II, and {{convert|6.5|km}} from the proposed Inga-III. The dam has an expected generating capacity of {{convert|39000|MW|abbr=on}}, with 52 turbines each with a capacity of {{convert|750|MW|abbr=on}}.[1] This is close to twice the capacity of the Three Gorges Dam, which is currently known as the largest energy-generating body ever built. The basisInga Falls on the Congo River is a group of rapids (or cataracts) in the latter portion of the Livingstone Falls. The Congo falls ~{{convert|96|m}} within this set of cataracts. The mean annual flow rate of the Congo River at Inga Falls is ~{{convert|42,000|m3/s}}. Given this flow rate and the 96 metre fall, the Inga Falls alone has a potential to generate ~{{convert|39.6|GW}} of mechanical energy and nearly as much electrical energy. Inga Falls is currently the site of two large hydro power plants and is being considered for a much larger hydro power generating station known as Grand Inga. The Grand Inga project, if completed, would be the largest hydro-electric power generating facility in the world. The current project scope calls for the use of a flow rate ~26,400 cubic metres per second at a net head of ~150 metres; this is equivalent to a generating capacity of ~38.9 GW. This hydro-electric generator would be more than double the current world record holder, which is the Three Gorges facility on the Yangtze River in China. Grand Inga is a "run-of-the-river" hydroelectric project in which only a relatively small reservoir would be created to back up the power of the river's flow. This would be so that the net head for the hydroelectric turbines could approach 150 metres. ProgressThe secretary general of the World Energy Council noted that the project is at a high level of success with the project being more feasible now than ever, during a two-day discussion regarding the development strategies.[2] As of January 2011, the project is in the feasibility study stage.[3] The project is expected to top US$100 billion in total development costs.[4][5] On May 2016 construction looked as if it would begin within several months.[6][7] However, on July 2016 the World Bank withdrew its funding following disagreements over the project. The first phase grant would have totaled US$73.1 million.[8] Some observers are skeptical of the project, citing its high cost in a country known for its endemic corruption—risking little benefit to the population.[9][10] See also{{stack|{{Portal|Democratic Republic of the Congo|Water|Renewable energy}}}}{{commons category|Inga Dams}}
