s and annual generation around 8.5 terawatt-hours. Although work at the site began in 1976 with a cofferdam completed in 1978, construction was suspended owing to a slowing of demand for electric power. The project resumed in 1985, with the first generating unit delivering power in 1990 and completion in 1992. Construction cost was $CDN 1.43 billion; favorable economic conditions at the time resulted in lower cost than budget.Manitoba Hydro
