The Manuel Piar Hydroelectric Power Plant (Tocoma Dam) is a stalled hydroelectric development project in the Lower Caroní River Basin of Venezuela. The project, started in 2006, includes the installation of 2,320 megawatts (3,110,000 hp) MW to generate annual average energy of 12,100 gigawatt-hours (44,000 TJ). As of 2019, the project is unfinished. The project was awarded to OIV consortium, consisting of Odebrecht (50%), Salini Impregilo (40%) and Vinccler (10%), with an initial budget US$3,061 mil. Ten Kaplan generator units, of 230 megawatts (310,000 hp), manufactured by an Argentinian company IMPSA, were predicted to begin operations between 2012 and 2014. These units had the world record as of 2012 in power generation at nominal head for Kaplan turbines. The diameter of the runner is 8.6 metres (28 ft) and nominal head is 34.65 metres (113.7 ft) with claimed output up to 232 megawatts (311,000 hp). The first generator was installed but not yet commissioned in April 2012. Behind schedule, the dam began to impound its reservoir on 16 November 2015. The budget tripled to $9,4 billion in 2017, as of 2019 the project is still unfinished. Odebrecht spent between 2007 and 2015 at least $118 million on bribes related to the project.
