Tidal energy has a low-frequency intermittent behavior and its predictability is guaranteed because it is related to astronomical phenomena. The North and Northeast regions have the largest tidal ranges on the Brazilian coast, ranging from 6 to 10 meters. In this article, a comparative performance's study of three configurations of a commercial hydrokinetic turbine, when subjected to the annual tidal profile observed in the Boqueirão Channel, using performance metrics based on the total energy production.
