Tidal energy is an environmentally benign, practical, and cost-effective renewable energy source. The hydropower potential appropriate site for electrical power production accessible in Bangladesh's coastline region is investigated in this article. We propose a model for determining the feasibility of power production via the tidal barrage system using a Compact Axial Kaplan (CAK) turbine in a low-head water turbine. Tidal power supplies enormous quantities of electrical energy in coastal locations across the globe without generating carbon or harming the environment. The world's wealthiest nations are increasingly resorting to tidal power generation. Where tidal power is available, we may be used tidal energy to alleviate the power shortage in coastal areas. A hydropower station may supply clean energy and fulfill a significant amount of the country's electrical demands. The notion of establishing a tidal power plant with a barrage model system would be a better long-term outlook for energy production and flourishing economic expansion. Dublar Char is an ideal location for tidal energy to be used to solve the electricity crisis in distant coastal regions. This article analyzes the electricity generating capability of Dublar Char, estimated at 120.17 megawatts (MW).
