Recent research led by Daniel Parrado from the Natural and Environmental Resources Engineering School at Universidad del Valle has unveiled promising opportunities for tidal energy development in Buenaventura, Colombia. Published in the journal Infrastructures, the study utilized advanced three-dimensional hydrodynamic and computational fluid dynamics (CFD) modeling to assess the feasibility of a tidal barrage power plant without sluicing in Buenaventura Bay.
Tidal energy is a renewable resource that harnesses the movement of tides to generate electricity. The study highlights that Buenaventura, located on the central coast of the Colombian Pacific, exhibits significant potential for this type of energy production due to its favorable tidal conditions. The research revealed that during specific tidal events, particularly the Syzygy phase, water velocities across the proposed barrage gates reached impressive speeds of 9 to 11 meters per second. This suggests a strong potential for electricity generation through tidal turbines.
Parrado noted, “The results during the Stoa condition were interesting because flow velocities higher than 1 m/s were not expected. This is promising because the plant might produce electricity even during the Stoa condition.” This finding indicates that the proposed tidal barrage could generate power during various tidal phases, enhancing its viability and reliability as a renewable energy source.
The commercial implications of this research are significant. As Colombia seeks to diversify its energy portfolio and reduce greenhouse gas emissions, tidal energy presents a sustainable alternative to fossil fuels. The potential for electricity generation in Buenaventura could not only meet local energy demands but also stimulate economic growth through job creation in construction, maintenance, and operation of the tidal power facility. Additionally, the development of tidal energy infrastructure could enhance local tourism and fishing industries by improving coastal resilience and connectivity.
Parrado’s research also emphasizes the need for further studies on water quality dynamics and the ecological impacts of constructing tidal barrages. He stated, “It is important to define which operation mode of the tidal barrage plant would be appropriate for Buenaventura Bay, not only in terms of power but also considering the dynamics of water quality and the risk of injuring native species.” This highlights the importance of balancing energy production with environmental stewardship.
As Colombia moves toward a clean and fair energy transition, the insights from this study provide a foundational understanding of how tidal barrage plants can be successfully implemented. The findings not only demonstrate the feasibility of generating electricity in Buenaventura Bay but also open the door for further exploration of tidal energy opportunities across the country. With continued research and investment, Colombia could position itself as a leader in marine renewable energy in the region.
