In 2013, personnel with Canadian provincial utility Hydro-Quebec performed penstock intake flow comparison tests to measure characteristics of the flow to its turbines at the Manic-5 powerhouse, part of the Daniel-Johnson hydroelectric facility, constructed between 1959 and 1970. Daniel-Johnson Dam is a multiple-arch buttress dam on the Manicouagan River that creates the Manicouagan Reservoir, 133 miles north of Baie-Comeau in Quebec, Canada. The facility produces hydroelectric power and supplies water to the Manic-5 and Manic-5-PA powerhouses that have a combined capacity of 2,596 MW. The dam is 702 feet tall by 4,311 feet in length making it the largest dam of its type in the world and one of the company's largest hydroelectric plants. Information from the tests allow plant engineers to achieve optimal performance from Manic-5's eight 190-MW Francis turbines.
